 I have problems with that to, on similar hardware, an Allwinner A20.
 I've not experimented with it much though, so you have gotten further
 than me.

 For what it's worth, I have the A13 as well, but that's not meant for 3D
 work.  The A20 is mine, the A13 belongs to a client.


Nice to know I'm not the only one. :-)

I think GLSL rendering problems or inconsistency are quite common as google
showed me.
evas-gl.c runs fine though.  Only Evas 3D examples are causing troubles...

 Hi Brian,

 Unfortunately, Evas 3D hasn't been extensively tested on a lot of GPUs,
 especially on the one that you're using.  From what I know about Mali
 400mp, it's an older GPU with separate vertext/fragment processors.  By the
 way, I'm not the one who developed the library so I don't know all the
 details.  From what I know about GPUs and from what I recall, it was only
 tested on a qualcomm mobile chipset.  The developement happened on a
 desktop machine.

 Looking at your description, it appears that Mali 400mp has a hard time
 processing the shader code for other types of lighting mode, which would
 inevitabily require more complex shader codes.  I guess one thing that you
 need to find out is if Mali400mp supports the kind of shader code that's
 there.  like the number of uniforms and the complexity of the code.  If it
 doesn't support the code, then i guess you'd need to figure out if you can
 do a workaround.  Unfortunately, both of these require good understanding
 of shaders.

 I'm CC'ing Taekyun, the guy who wrote most of it, so he can aslo respond.

 Sorry for the late response.  I got completely swamped with work after the
 weekend.

 Hope you can get it sorted out.



Thank you, Sung.

I digged further and found:
--- Renders fine, SHADE_DIFFUSE ---

VERT_SRC
uniform mat4  uMatrixMvp;
attribute   vec4  aPosition0;
void main() {
vec4 position = vec4(aPosition0.xyz, 1.0);
gl_Position = uMatrixMvp * position;
}

FRAG_SRC
#extension GL_OES_texture_npot : enable
precision highp float;
uniform   vec4uMaterialDiffuse;
void main() {
gl_FragColor = uMaterialDiffuse;
}
---

--- No rendering at all, and it does not look too complex...
SHADE_VERTEX_COLOR ---
VERT_SRC
uniform mat4  uMatrixMvp;
attribute   vec4  aPosition0;
attribute   vec4  aColor0;
varying vec4  vColor;
void main() {
vec4 position = vec4(aPosition0.xyz, 1.0);
vec4 color = aColor0;
gl_Position = uMatrixMvp * position;
vColor = color;
}

FRAG_SRC
#extension GL_OES_texture_npot : enable
precision highp float;
varying  vec4vColor;
void main() {
gl_FragColor = vColor;
}
---

I played with the VERTEX COLOR part a bit and made some modifications on
the color (aColor from vec4 to vec3):
---
VERT_SRC
precision mediump float;
uniform mat4  uMatrixMvp;
attribute   vec4  aPosition0;
attribute   vec3  aColor0;
varying vec4  vColor;
void main() {
vec4 position = vec4(aPosition0.xyz, 1.0);
vec4 color = vec4(aColor0, 1.0);
gl_Position = uMatrixMvp * position;
vColor = color;
}

FRAG_SRC
precision mediump float;
varying  vec4vColor;
void main() {
gl_FragColor = vColor;
}
---

Now it renders!  I don't know why though...

Hopefully, this would give the experts more clues on what is wrong.

[E-devel] Problem running evas_3d_cube example

[Brian Wang]

Hello all,

I tried to run evas_3d_cube example on my board.  Lots of error messages
output like these:
---

EFL version is 1.11.  I had the gears test of elementary_test running ok.
I have no clue if this is my environment setup or a problem with EFL.

Any hints will be appreciated.

Thanks in advance.

Yes, elementary_test is run with ELM_ENGINE=gl.  The gears spin smoothly
without problems.
It is the evas_3d_cube and other evas 3D examples that are causing the
problem.

Is it a setup problem?

Thank you.

On Fri, Nov 7, 2014 at 6:28 PM, Sung W. Park sung...@gmail.com wrote:

 I could be wrong but it seems like your gles compiler's complaining about
 precision not being set in the shader.

 Some GLES compilers will complain and others gracefully ignores it if one's
 not found.

 I don't have time to look at the code as I'll be away for the weekend but
 you may look at the evas_3d  fragment shader code and see if there's
 something like

   precision mediump float;\n  or
   precision highp float;\n

 is in there somewhere

 that would be my guess.


Thank you for the hint.

I added to evas_gl_3d_shader.c:_fragment_shader_string_variable_add() the
following lines:
---
  ADD_LINE(#extension GL_OES_standard_derivatives : enable);
ADD_LINE(precision mediump float;);
ADD_LINE(precision mediump int;);
ADD_LINE(precision lowp sampler2D;);
ADD_LINE(precision lowp samplerCube;);
---

Now, evas_3d_cube does not complain about no default precision defined
anymore.
The first line is required for dFdx, dFdy(), fwidth according to the doc
(at least for OpenGL ES 2.0):
https://www.khronos.org/registry/gles/extensions/OES/OES_standard_derivatives.txt

However, there is nothing shown on the screen and there is no warning
message at all.

Running evas_3d_aabb will show the size-changing box but without the
animated Sonic figure.
I have no clue on how to solve the problem.

When running the evas_gl example, there are lots of warning/error messages:
---
ERR909:EvasGL modules/evas/engines/gl_common/evas_gl_core.c:1100

---
There is a 3D box shown.  However, when compared to the one running on my
x86 box, the colors and the sides are different.
Maybe this is a separate problem.

I am running EFL on Allwinner A13 with ARM Mali-400 MP (binary MALI r3p0).

Thanks in advance.

Hello all,

More findings here:

For EFL/Elementary 1.10.3, a sample gdb trace looks like when using edje

For EFL/Elementary 1.11.x, no elm_object_style_set will be called.
 Something's wrong with the from_params parameter when calling
external_common_state_set().

ExtButton of elementary_test will show blank buttons.

Hope it helps.

[E-devel] Elementary edje_externals Label Problem

[Brian Wang]

Hello all,

I just pulled the latest EFL and Elementary from git.
The labels on the buttons within all the ExtButton, ExtSlider, Ext* tests
of elementary_test are all blank.  No text is shown.

I am wondering if I am the only one having the problem, as my upgrade
method may not be proper.

Thanks in advance.

Hello all,
   
Are there any advantages when using the gl-x11 backend vs
 X11+software
rendering?
Any performance boost?
   
I am now on a ARM Cortex-A8 processor with a MALI GPU and wondering
 if I
should go through the hassle of setting up the driver/library.
   
Thanks in advance.
   
it depends, gl can be faster than the cpu - in many cases. but it
   comes at a
memory cost too. try and find out. it'll depend on each case
  
   And battery also. It depends on the application...
  
 
  OK.
  I thought that if I am only doing 2D graphics, gl won't be much help.
  Do blitting and scaling go through gl too or are they done in software
 only?
  Please bear with me since this is obviously a newbie question...
  I could not find any info on how each backend helps rendering.

 fgor the gl back end all operations are done with the gpu (except
 generation of
 font glyphs from ttf files and loading/decoding of images). blitting and
 scaling are just bi-products of drawing triangles. evas actually never
 blits
 in the sens that things that scroll get copied around the screen to make
 them
 move like traditional widget sets. every change is a redraw of the area
 that
 changed (that are may expand to the whole window/screen depending on back
 end
 etc.).

 so scaling an image in gl is drawign 2 triangles with a texture so the
 tringles cover an area of a different size to the texture. blending may be
 on
 or off depending if it's needed.

 the software engine just does all of these operations with the cpu instead.


OK.

I finally got some time to put the EGL-x11 driver all together.
The GLView Gears and GLView Many Gears tests in elementary_test work.
'top' shows elementary_test is eating 34% of CPU and X is eating 14% of CPU
when running
the GLView Many Gears test.  Are the figures reasonable?  This is the first
time I am
using a chip with a GPU...

When running other tests, I could not tell the difference between x11 and
gl backends except
that when running with gl, sometimes the test window of elementary_test
does not show up
properly.  It is invisible until I touch the window area...  Probably due
to faulty GPU drivers, but
I have no clue how to debug it...


Brian




  Thanks.

[E-devel] [PATCH] elm_index : set it-letter to NULL after eina_stringshare_del

[Brian Wang]

Hello all,

In elm_index.c, _item_del_pre_hook calls _item_free, where it-letter
is not set to NULL after eina_stringshare_del.
This will cause invalid access later on.  The attached patch fixes the
problem, which is reproducible in my code before the fix.
Please check if this makes sense.

I am sorry that I was unable come up with a simple test app to
demonstrate the problem.

Thanks in advance.

 Hey,

 Added a fix/workaround for your issue: r75730.

 The problem is that fit was only added recently and wasn't really tested or
 used. The second problem is that fit kinda changes how edje handles
 textblock and we now need to do fancier stuff like we do for text objects,
 e.g splitting recalc and recalc apply. This is a patch on the way to there.

The fix is good for the both the simple test case and my application.

Thanks!

  Git is able to clone from http protocol. So just give it the http://
  url and it will work out its magic.

 Thanks for the quick response.

 You mean something like this:
 1.  git clone http://git.enlightenment.fr/vcs/svn/eina.git
 -- just waits indefinitely
 2.  git clone http://git.enlightenment.fr/eina.git
 -- gives fatal: http://git.enlightenment.fr/eina.git/info/refs
 not found: did you run git update-server-info on the server?

 I am not sure about the URL.  Could you give me an example for cloning eina?

 
  By the way, I created clones of the main libraries on gitorious, which
  also supports git protocol. At the moment I'm updating the
  repositories every 5 minutes.
 
  http://gitorious.org/enlightenment

 I did find your git repos on gitorious.  It just isn't clear if this
 is a repo with your own patches or it is a purely a git-svn updated
 repo from the official svn repo.

 The French git is mentioned in
 http://www.enlightenment.org/p.php?p=contribute.
 If your gitorious repo is synced with the official svn, it should
 probably be listed on that page too. :-)

 What about

 git://git.enlightenment.org/git/e.git

This works!
How frequently is this synced with the official svn?

Thanks.  :-)

Yes!  It does work!  You must be a very patient man.

Thanks for trying. :)


brian

  From gitorious, it works too, just move to HTTP
 (https://git.gitorious.org/enlightenment/eina.git) and clone.

 Git is able to clone from http protocol. So just give it the http://
 url and it will work out its magic.
 Thanks for the quick response.

 You mean something like this:
 1.  git clone http://git.enlightenment.fr/vcs/svn/eina.git
  -- just waits indefinitely
 2.  git clone http://git.enlightenment.fr/eina.git
  -- gives fatal: http://git.enlightenment.fr/eina.git/info/refs
 not found: did you run git update-server-info on the server?

 I am not sure about the URL.  Could you give me an example for cloning eina?

 By the way, I created clones of the main libraries on gitorious, which
 also supports git protocol. At the moment I'm updating the
 repositories every 5 minutes.

 http://gitorious.org/enlightenment
 I did find your git repos on gitorious.  It just isn't clear if this
 is a repo with your own patches or it is a purely a git-svn updated
 repo from the official svn repo.

 The French git is mentioned in
 http://www.enlightenment.org/p.php?p=contribute.
 If your gitorious repo is synced with the official svn, it should
 probably be listed on that page too. :-)
 What about

 git://git.enlightenment.org/git/e.git

 ?

 Thanks.


 Brian

 Best regards, Etrunko

 Thanks in advance.

[E-devel] [BUG REPORT] elm_genlist inside elm_flip does not work

[Brian Wang]

Hello all,

For the recent elementary version, it seems that genlist does not work
when set inside elm_flip.  It used to work though.

Please refer to the short test code attached.  I totally have no clue
what went wrong...

Thanks in advance.

[E-devel] [BUG REPORT] elementary does not compile when EMAP support is turned off

[Brian Wang]

Hello all,

If HAVE_ELEMENTARY_EMAP is not defined, elementary does not compile.
I commented out some parts, added some semicolons and fixed some
spellings to get it compiled.

What I did is attached just for reference, as I did not check if it
affects when HAVE_ELEMENTARY_EMAP
is defined...

Thanks.

[E-devel] Possible Unmatched LKL and LKU in _ecore_thread_shutdown

[Brian Wang]

Hello all,

In ecore_thread.c:_ecore_thread_shutdown(),
   if there is still some _ecore_running_job,
   ecore_thread_cancel() will be called while
_ecore_pending_job_threads_mutex is being held.
In ecore_thread_cancel(),
   it will try to acquire the same mutex, causing
_ecore_thread_shutdown() to freeze.

That's how I read the code while I was trying to debug why my app does
not shutdown completely (there
is a thread running, without being cancelled before calling elm_exit()).

I do not know how to fix it other than moving LKU before calling
ecore_thread_cancel; however, I do not know
if it's safe to do or not.

Thanks in advance.

it will try to acquire the same mutex, causing
 _ecore_thread_shutdown() to freeze.

 That's how I read the code while I was trying to debug why my app does
 not shutdown completely (there
 is a thread running, without being cancelled before calling elm_exit()).

 I do not know how to fix it other than moving LKU before calling
 ecore_thread_cancel; however, I do not know
 if it's safe to do or not.

 Sadly, it is not as we need to take lock as long as we walk on that
 list. I will look at it and find a proper solution, but basically
 ecore_thread_cancel doesn't access the same list. So either I use
 another lock when accessing the _ecore_running_job or I tell somehow
 ecore_thread_cancel to not even try to access the
 _ecore_pending_job_threads and _ecore_pending_job_threads_feedback.
 Need to think, quickly, about it. I need to fix that before EFL
 release.

 Ok, fixed in r74953 by using another mutex.

Nice!  Tested!

Thanks. :-)

[E-devel] [BUG REPORT] Elementary, elm_genlist invalid access

[Brian Wang]

Hello all,

A large genlist within my app crashed here and there.  valgrind helps
point out an invalid access.
I do not know the exact sequence of how it occurs but it must have
something to do with race conditions
that probably only show up where the cpu is slow (running with
valgrind would do it on my desktop too).

Please find below a trivial inline patch to fix the problem.  Hope
it's the right fix. :-)

[E-devel] [BUG REPORT] edc 'inherit' keyword causing problems

[Brian Wang]

Hello all,

I am not sure if this is intended.  However, it used to work.

Case : A part with multiple states (sizes)
State #1 : default
State #2 : inherit State #1, with different size (different rel1, rel2)
-- State #2 seems to fail to change the rel1 and rel2 properties.

Please see the attached edc file for the demonstration of the problem.

Thanks in advance.

I just compiled jpeg62 lib and installed it to a tmp directory.
I am overring the LIBS, CFLAGS and LDFLAGS variables for eet and evas.
 Now they seem to be using the old libjpeg62 now.

Now, finally, compiling edc files works properly with 'LOSSY' and
without seg faults.  elementary_test is working properly finally as it
does not seg fault here and there!  I guess it's the new libjpeg8
stuff that is causing the troubles.  I will live with this for now :-)

However, there seems to be some momentum upgrading libjpeg to
libjpeg8/libjpeg-turbo8 for various Linux distros.  Fixing the issue
with libjpeg8 will be nice. :-)

[E-devel] [BUG REPORT] edje_cc seg fault

[Brian Wang]

Hello list,

I just checked out the latest EFL but failed to complete compilation.

The first thing to fail is that edje_cc doesn't seem to like LOSSY n
in some of the edc files.  I just changed them to COMP to pass the
compilation.

The next thing is when building elementary/data/objects/test.edj,
edje_cc seg faults.  Here is the relevant part of valgrind complaints:

[E-devel] Is Evas Compatible with libjpeg8/libjpeg-turbo8?

[Brian Wang]

Hello all,

I am using the latest EFL from svn.

The previous problem with edje_cc was related to references to sky.jpg
in elementary/data/objects/test.edc.
When I played a bit with elementary_test, it is getting faults here
and there.  glibc backtrace shows invalid free
in jpeg loader.  Therefore, I suspect there is something wrong with
the JPEG code.

I just upgraded to Ubuntu 12.04 and do not know if this touches the
default libjpeg in the system.

Thanks in advance.


Brian

sky.jpg is there though.

Is it the same issue as this one?

The system jpeg library is libjpeg8.

You mean the eina utf8 functions or elm_diskselector?

[E-devel] [BUG REPORT] elm_diskselector : Bad text cutting with non-ASCII characters

[Brian Wang]

Hello all,

elm_diskselector seems to support only ASCII characters when cutting
the text strings at the sides.
_check_string/_check_letter() may be examined.

Does evas has some handy exported functions to cut the text at proper
UTF-8 character boundaries?

Thanks in advance.

Hello all,

In some cases, evas_textblock_cursor_content_get() would seg fault due

The patch tries to avoid that.

Please check the attached trivial patch and adjust it as you see fit.

[E-devel] [BUG REPORT] elm_genlist/Edje : Invisible Text When Switching the Elipsis Attribute of an Item

[Brian Wang]

Hello all/tasn,

This is definitely a bug but quite tricky to reproduce the problem.
I'll do my best to describe the problem and my observation.

I have a custom compressed genlist theme, which sets the elipsis
attribute to 1.0 when an item is selected.
The label part of a genlist item with the label of a certain width
will become invisible when selected.
The _magic_ width of course depends on a certain combination of the
genlist scale, the text string and the font.  Thus it may be difficult
to reproduce the problem on different systems.  Probably some boundary
case in the text cutting code...

Please let me know if there's anything else to test or report.

Thanks in advance.

[E-devel] [BUG REPORT] elm_genlist : Missing ASCII Characters When the Label Contains Mixed Chinese and ASCII Characters

[Brian Wang]

Hello all,

I just svn'd up (r59145) and found this strange problem.

When a genlist item's label contains mixed Chinese and ASCII
characters, the ASCII characters within the string are all gone!
For example,   _CHINESE_ will be displayed for the actual string, 1
_CHINESE_.

Please see the attached for the demonstration of the problem.

[E-devel] Is it possible to make elm_scroller always show an item?

[Brian Wang]

Hello all,

The widgets are:
an elm_scroller contains an elm_box, which packs a list of elm_entry objects.

Loading a long list of elm_entries (100+) is somehow slow on my device
and the user may skip to the very end of the list.
Therefore, to improve responsiveness, when the user skips to a
particular entry, that entry is loaded immediately and the ones below
are loaded subsequently in an idler.
There is an entry populating idler that will later pack the remaining
elm_entries above the entry being viewed.  However, when the ones
above the currently viewed entry are getting packed into the elm_box,
the entry being viewed will be pushed down and go off screen.

Is there a way to maintain the viewport of the scroller, or fix the
viewport on a particular object?  Or there's a better way of handling
this?

Thanks in advance.

[E-devel] elm_scroller : _focus_region_hook() behaviour

[Brian Wang]

Hello all,

The current elm_scroller.c:_focus_region_hook() behaviour is somehow
troublesome.  The code snippet is pasted below.

Why does it scroll?  When I press/click on a scroller, the viewport
seems to change and the sudden jumpy change is annoying (at least to
me).  I commented out the code and have not found any strange
behaviour but I would like to know the reasoning of the code.

Thanks in advance.

static void
_focus_region_hook(Evas_Object *obj, Evas_Coord x, Evas_Coord y,
Evas_Coord w, Evas_Coord h)
{
   Widget_Data *wd = elm_widget_data_get(obj);
   if (wd-scr)
 elm_smart_scroller_child_region_show(wd-scr, x, y, w, h);
}

 Hi,

 So I've been a bit surprised by the change of icons in elm_toolbar
 from an Evas_Object * into a const char *.

 How do I use an icon not predicted by elementary now?

 elm_theme_overlay_add() your theme file, which contains
 elm/icon/toolbar/YOUR_ICON_NAME/default as the group.  Just copy and
 modify the part of the icon section of elementary's default.edc.

 I was surprised too. :-)

 Isn't that a bit too excessive just to change *one* icon?

Forwarding this to the list...

[E-devel] [BUG REPORT] evas / fontconfig problem? Chinese display problem

[Brian Wang]

Hello all,

I just svn'd up and my app doesn't show Chinese characters properly
anymore.  All of them become square blocks...
I tried embedding fonts in my theme file and it worked.  Thus,
probably a fontconfig usage problem?

Any pointers?

Thanks in advance.

 Can you by any chance tell from what revision and to what revision you
 updated?

Sorry... I should have written down the revision number before any update.

Anyway, I remember my previous bug report of elementary_config's
needing efreet and raster fixed it quite soon in r53945.
And r54074 is causing the problem.

I do keep the list of files updated for svn up.  For evas, it touches:
Uevas/src/lib/cache/evas_cache_image.c
Uevas/src/lib/include/evas_common.h
Uevas/src/lib/engines/common/evas_font_draw.c
Uevas/src/lib/engines/common/evas_font_load.c
Uevas/src/lib/engines/common/evas_font_private.h
Uevas/src/lib/engines/common/evas_font_query.c
Uevas/src/lib/engines/common/evas_font_main.c
Updated to revision 54074.

Is the info enough?

 Thanks,

 Seems so.

 Please try using commit 53986 (I think 53987 broke it, and that's the
 latest anyway). Does it fix it?

 Commit 53987 looks like it did evil stuff with the higher Unicode values
 (for example, Chinese), maybe that's it.

 Please let me know,

Right on!
With r53896, Chinese characters are shown properly.
With r53986, they become rectangles.

 lack of advertising when changes on elm API are made.

OK.  That seems to be me. :-)
However, I did suggest making a note on the subject line of the e-svn
mailing list mails whenever the API is touched.  Something like [API
CHANGE].  The subject line is where people, at least me, scan quickly
for something interesting.  If the particular commit touches whatever
I'm working on, I would expand the mail and read the commit message.

But I guess maybe there's some technical difficulty with it to make it
automatic.  Don't know...  I hope there's a better way that draws
attention to warn EFL users about API changes since API changes are
quite _scary_ when the application in development is to be shipped
commercially...

The heads-up warning is appreciated. :-)

 least trim the email so it's not got 64KB of code patch if all they
 need is to be informed.

 OK, I'll do it next time.

[E-devel] [BUG REPORT] invalid access to eina chained mempool (elm_toolbar_add - elm_theme - edje - eina mempool)

Hello list,

I just svn'd up.  A simple elm_toolbar_add call triggers this.  Don't
know which part of EFL is at fault (probably due to the newly
introduced valgrind macros in eina mempools?).

  doxyegen doc comments. should they go in .c files or in .h files? good
  question. eet has it all in Eet.h. the rest of efl has it in .c files. a
  good case has been made for it being in .h files instead of .c - that
  developers actually do read the .h files and then dont see the docs. they
  need to go get the src separately OR find the separately generated docs.
  having it all there in 1 place already shipped and installed is useful as
  docs are ready to read without needing to find the pretty generated html
  ones (or man pages). another bonus - it's instantly obvious what functions
  are and are not documented.
 
  what do people think? move docs to .h file(s)? (its really mostly a
  mechanical thing).
 
  It make a lot of sense to have the doc in the public header indeed. So
  I would vote for that too.

 -1 as it gets out of sync much easier, makes .h cluttered to be read
 by humans (elementary and evas are already bad)

 aaah. and this is actually the point made for having it there. if efl is
 released 1.0 - it gains many new novice efl users. they NEED docs. they are
 not experienced. they are not after a shorthand reference of function names.
 the first place they look is the header files and they are not finding the 
 docs
 there. so for us few experienced people they get cluttered - and that was part
 of the consensus. but when we are outnumbered 100:1 with novices looking for
 info... then this changes the view a bit - and the case has been made to me
 that this is actually happening already. we just don't know about it 
 happening.
 thus this email about it.

Count me in as a novice EFL user.  This is how I find the functions I need:
1.  Look into /usr/include/xxx/xxx.h
2.  If the header doesn't explain itself well, I'll google the
function.  Normally, the auto-generated doc goes to the top of the
search results.  However, sometimes it's buried in the search results.

IMHO, put docs in the source and let doxygen generate beautifully
formatted HTML.  Put the URL of the auto-generated docs of the library
on the top of the header file to make it easier to find.  If the
naming of the API is somehow confusing, simple docs in the header file
help too.

Reading doxygen comments isn't exactly a quick read and it doesn't
provide linking in the raw form.  Probably some vim plugins would
help...  Thus, cluttering the header file with doxygen comments will
make the header file more difficult to read.

By the way, I tried 'make pdf' and the resulting PDF doc is kind of
ugly, font-wise.  Is it a latex thing or is it because of my system
setup?  Beautiful doxygen-based PDF doc files are good too when I go
offline...

That's my two cents.

 so far i'd say the opinions are about evenly divided here. that makes this
 pretty much a 6 or half a dozen change so far.

   ok as a general thing. this isn't any api break.
  
   doxyegen doc comments. should they go in .c files or in .h files? good
   question. eet has it all in Eet.h. the rest of efl has it in .c files. 
   a
   good case has been made for it being in .h files instead of .c - that
   developers actually do read the .h files and then dont see the docs.
   they need to go get the src separately OR find the separately generated
   docs. having it all there in 1 place already shipped and installed is
   useful as docs are ready to read without needing to find the pretty
   generated html ones (or man pages). another bonus - it's instantly
   obvious what functions are and are not documented.
  
   what do people think? move docs to .h file(s)? (its really mostly a
   mechanical thing).
  
   It make a lot of sense to have the doc in the public header indeed. So
   I would vote for that too.
 
  -1 as it gets out of sync much easier, makes .h cluttered to be read
  by humans (elementary and evas are already bad)
 
  aaah. and this is actually the point made for having it there. if efl is
  released 1.0 - it gains many new novice efl users. they NEED docs. they
  are not experienced. they are not after a shorthand reference of function
  names. the first place they look is the header files and they are not
  finding the docs there. so for us few experienced people they get cluttered
  - and that was part of the consensus. but when we are outnumbered 100:1
  with novices looking for info... then this changes the view a bit - and
  the case has been made to me that this is actually happening already. we
  just don't know about it happening. thus this email about it.

 Count me in as a novice EFL user.  This is how I find the functions I need:
 1.  Look into /usr/include/xxx/xxx.h
 2.  If the header doesn't explain itself well, I'll google the
 function.  Normally, the auto-generated doc goes to the top of the
 search results.  However, sometimes it's buried in the search results.

 IMHO, put docs in the source and let doxygen generate beautifully
 formatted HTML.  Put the URL of the auto-generated docs of the library
 on the top of the header file to make it easier to find.  If the
 naming of the API is somehow confusing, simple docs in the header file
 help too.

 Reading doxygen comments isn't exactly a quick read and it doesn't
 provide linking in the raw form.  Probably some vim plugins would
 help...  Thus, cluttering the header file with doxygen comments will
 make the header file more difficult to read.

 By the way, I tried 'make pdf' and the resulting PDF doc is kind of
 ugly, font-wise.  Is it a latex thing or is it because of my system
 setup?  Beautiful doxygen-based PDF doc files are good too when I go
 offline...

 That's my two cents.

 the html docs should work offline too... just bring up index.html in a 
 browser.

Yes, it works!  Cool!

 Subject: E SVN: acidx IN trunk/TMP/st/elementary/src: bin lib

 Log:
  [Elementary] Use elm_icon_standard_set() on Elm_Menu items.

  This breaks the API *and* the ABI, but this should be consistent with
  Elm_Toolbar.  We'll probably need a tweak here and there, but I really
  think Elm_Menu should be rewritten.

 Sorry, the API is not 1.0 so we can do it (yet, probably last month).
 It was discussed at irc only. As Leandro said, few others may change,

 It's for good, but an annoyance :(

Perhaps, we may get some warnings on the dev list about modifications
to the existing API?

 That's a good practice I try to do, but sometimes it slips. However
 this one was mentioned in the e-svn ml.

You mean r53407 commit?  The subject line for e-svn ML, which I assume
is automatically generated by a post-commit script, only shows the
files that commit touches without a [WARNING: API Change] tag or
something like that.

Is it possible to monitor the commit diff that if there are changes to
header files, put a nice little warning prefix to the subject line?
Just an idea. :-)

Hello all,

It turns out that I'm not using elm_entry_cursor_content_get()
correctly.  I just assume it would return NULL if there's something
wrong.  Therefore, the infinity loop is my bad.

Sorry for the false alarm.

 Hello all,

 I'm using a fairly recent svn version (r53178).  Calling
 elm_entry_cursor_next() under a certain circumstance will cause an
 infinite loop somewhere.

 I'll try to describe the problem in my best:
 ---
 I have:
 elm_bubble
  |--- elm_scroller
            |--- elm_entry
 The elm_entry contains only a single line.  Pressing (mouse,down) on
 the elm_entry obj will in turn call elm_entry_cursor_next().
 The infinite loop happens when the mouse is clicked at the very bottom
 of elm_entry obj.  There seems to be nothing (no text) at the clicked
 point.

 If you need more information, please let me know.  It's probably very
 specific to my environment (theme).

[E-devel] [Question] How to use the new Elementary toolbar API (elm_toolbar_item_add) to load non-standard icons

[Brian Wang]

Hello list,

I just svn'd up and found elm_toolbar_item_add() API is modified to
take an icon string instead of the old Evas_Object * as its icon.
I have bunch of dynamically loaded icons (associated with modules
within subdirectories) and they are not part of a standard theme file.

How do I set the toolbar icons with the new API?

A side question: How is this kind of API change discussed?  As an EFL
user, I find it sometimes quite troublesome failing to compile my apps
after a svn update.

Thanks in advance.

[E-devel] [BUG REPORT] Edje edje_object_part_text_cursor_next() never returns (infinite loops)

[Brian Wang]

Hello all,

I'm using a fairly recent svn version (r53178).  Calling
elm_entry_cursor_next() under a certain circumstance will cause an
infinite loop somewhere.

I'll try to describe the problem in my best:
---
I have:
elm_bubble
  |--- elm_scroller
|--- elm_entry
The elm_entry contains only a single line.  Pressing (mouse,down) on
the elm_entry obj will in turn call elm_entry_cursor_next().
The infinite loop happens when the mouse is clicked at the very bottom
of elm_entry obj.  There seems to be nothing (no text) at the clicked
point.

If you need more information, please let me know.  It's probably very
specific to my environment (theme).

The gdb backtrace (captured when it's in some loops and I interrupted
in the middle of the loops):

[E-devel] [PATCH] _edje_text_fit_x problem with non-ascii strings

[Brian Wang]

Hello list,

Edje's text chopping code seems to be mixing up the usage of UTF-8
character index with Unicode character index.  This causes Chinese
text strings to be cut off at the very beginning leaving lots of
spaces following the elipsis.

Please see the patch for the fix/hack.  And it's not a properly patch
since my own comment is not removed.

Thanks in advance.

[E-devel] [Question] Is it possible to copy the image snapshot of an Evas_Object to another Evas_Object?

[Brian Wang]

Hello list,

My question is pretty much as the title.

I want to take a snapshot (just the rendered image) of an Evas_Object
to another Image Evas_Object and so some effect on the new object.
It's like store a screenshot of an evas object in another evas object.

Thanks in advance.

 I put everything in edje_private.h. I don't like that at all, but it was the

 update edje and try again

Nice!  It's working again!

 Those changes are printf left-overs while I was debugging EFL startup

 I'll try with cross compilation too

 I tried, and I have no problem :/

 in elm top dir, run:

 make maintainer-clean
 ./autogen.sh --prefix=/home/torri/local/mingw --host=i586-mingw32msvc
 --with-edje-cc=~/local/e17/bin/edje_cc --with-eet-eet=~/local/e17/bin/eet

 replace the prefix, host and edje_cc/eet values by what suit your
 configuration, and tell me if there is still the problem

Hello Vincent,

After make maintainer-clean, the problem persists.

Actually, there are two problems with elementary when compiling with
cross mingw32.  edje_externals is one of them.  The other one was
mentioned in my previous emails regarding having to pass
ELEMENTARY_WIN32_LIBS=\-lecore_win32 -levil -ldl\ to
autogen.sh/configure in order for the core elementary to be built.
IIRC, you said you have no problem without passing
ELEMENTARY_WIN32_LIBS.

Is there any chance that you have set some env variables in your bash
rc file that might solve the problem automagically?

 I don't think so. Remove ELEMENTARY_WIN32_LIBS and give me the error and
 the
 link command (don't forget V=1)

 As attached.

 There is something very strange : evil does not appear. Are you sure you
 have compiled and installed it ?

Yes.  The rest of EFL (evas, ecore, edje, etc.) compiles just fine and
I think they depend on evil as well?

 Hey,

 I've followed the guide
 @http://trac.enlightenment.org/e/wiki/EFLWindowsXP.
 Thanks to the wiki, with just a few glitches, I've finally built my
 EFL + Elementary!!!

 The question now is: how do I move the whole runtime environment of
 EFL to Windows (XP)?
 My dev/compile environment is:
 * x86 ubuntu box
 * i586-mingw32msvc cross toolchain

 1) just get the DLL (EFL + dependencies). Not easy, as, for example, evas
 modules must be placed correctly.

 2) you can use on Windows the MSYS/MinGW SDK I created to have a working
 environment:

 http://www.maths.univ-evry.fr/pages_perso/vtorri/files/msys.7z

 Untar it (using 7zip for example) in a path without space. You'll be able to
 launch an MSYS terminal. All the needed dependencies should be there. Just
 check out the libs and compile them using the wiki.

I'm sticked to my linux box...  It's a personal preference.  I feel
much more comfortable with ubuntu.


 3) You can wait 2 days. I'll finish a new installer quite soon.

 Vincent

 PS: if the wiki has some errors, please fix them or report them to me.

How do I fix them (wiki) or how do I report them?  Sorry, newbie question...

 @http://trac.enlightenment.org/e/wiki/EFLWindowsXP.
 Thanks to the wiki, with just a few glitches, I've finally built my
 EFL + Elementary!!!

 The question now is: how do I move the whole runtime environment of
 EFL to Windows (XP)?
 My dev/compile environment is:
 * x86 ubuntu box
 * i586-mingw32msvc cross toolchain

 Thanks in advance.

 why would you want to? :)

 I'm writing a WIN32 gui helper utility for my device.  I'm using
 wxWidgets right now and after some experience of EFL, I feel like
 moving to EFL (a lot fancier).  I want to package the
 app/libraries/config files in one self-contained file.  Maybe the
 question should be how to package my EFL app?

 I've figured out some parts.  elementary_test.exe runs on my Windows
 XP but it feels _slow_ (a lot slower than wxWidgets).  Maybe it's
 because it's running inside VirtualBox.  I'll definitely test it on a
 native Windows box.

 Windows is slow, so Windows in VirtualBox... Well, there are several reasons
 why it is slow:

 * The quantity of messages sent via printf is just too huge. I'm sure it
 slow down the app.
 * are you sure you compiled with -O2 or -O3 ?

yes (-g -O2).

 * for now, only GDI (the default) and DirectDraw are working. I had no time
 to update the gl engine, nor the direct3d one. GDI is slow, as it is not
 hardware accelerated.

So, I should switch to DirectDraw and that is working properly?


 I'm still trying to figure out how to get my font right.   The font
 used in elementary_test.exe looks ugly...

 Well, I have nice fonts. Note that if your fontconfig setup is messed, the
 chosen fonts will be ugly.

Any example fontconfig setup files?  I'll play with it a bit.  Thanks. :-)

 about a self contained file, everything can be linked statically. I tried it
 on Linux and it works (it's just a matter of passing the correct flag to
 libtool). I think it should work on Windows too

Can evas modules be statically linked too?
Since my app is the sole user of EFL, I guess it's better to
statically link all the stuff to save some space and that should also
improve the startup speed.  That's what I'm going to try next.

 I'm sticked to my linux box...  It's a personal preference.  I feel
 much more comfortable with ubuntu.

 then use wine, it should work.

 PS: if the wiki has some errors, please fix them or report them to me.

 How do I fix them (wiki) or how do I report them?  Sorry, newbie
 question...

 report them to me. Privately or in the ML. That will be sufficient

OK.  I'll definitely do that after some experiments. :-)


 thank you

Re: [E-devel] EFL on WindowsXP Slowness (Startup time) --- eet_open()

[Brian Wang]

On Thu, Sep 16, 2010 at 1:13 PM, Vincent Torri vto...@univ-evry.fr wrote:

 Hey,

 EFL/Elementary app is slow to launch on Windows XP (gdi-based).
 Please find the log (captured by Process Monitor) in CSV format as
 attached.  There will be some garbage characters displayed (Chinese
 characters, I think).  Please ignore them.

 Here are the two lines with big timestamp gaps:
 *
 09:54:11.0247158,eMBK.exe,3204,RegCloseKey,HKLM\System\CurrentControlSet\Services\WinSock2\Parameters,SUCCESS,
 *
 09:54:17.9069715,eMBK.exe,3204,CreateFile,C:\home\kma\local\mingw\share\elementary\config\profile.cfg,PATH

 -- 6.x seconds!!!

 strange :-) When i launch elementary_test, it takes less than 2s

 Anyone knows what EFL is doing right before opening elementary's
 profile.cfg?  There's no stdout/stderr message in between.

 I have to look at the code, i don't know that part.

 Anyway, process monitor could be a good tool, but it's hard to find
 informations in the main window. Too much garbage...

I just did a dummy printf exercise and found
eet_open($HOME/.elementary/config/profile.cfg) is causing the
slowdown:

elementary/src/lib/elm_config.c:_profile_get()
   // usser profile
   snprintf(buf, sizeof(buf), %s/.elementary/config/profile.cfg, home);
   ef = eet_open(buf, EET_FILE_MODE_READ);

The file passed to eet_open() does not exist on my system.  I just
commented out the code and set ef to NULL.  Now elementary_test.exe
and my testing eMBK.exe pop up within 2 seconds!  Much better and good
enough for now!

I briefly looked at eet_open code.  It's not a straight file open/read
stuff and involves with some cache mechanism.  That's probably causing
the problem.  I'm moving on as a happy EFLWindowsXP user!

[E-devel] [BUG REPORT, RE: Edje cursor content get?] elm_entry_cursor_content_get BROKEN with tags

[Brian Wang]

Hello all,

If there are tags (babc def/b) in elm_entry,
elm_entry_cursor_content_get() returns the wrong character.
It seems to be off by the length of the starting tag and may be short
due to the closing tag.

Please see the attached source for demonstration of the problem.

 Hi Brian,

 This is not an official one, but if everyone else approves, it could
 be. Feel free to use it:

 Of course some designer could send some idea too, but it hardly can
 become better than this one.

 PS: The drawing was made by Luis Felipe (lfelipe) and I colored it.

 We already told you guys : NEVER DO DESIGN AND DRAWING AGAIN ! GO BACK TO 
 CODE !

Good advice. :-)

 Hello raster,

 I stole some time and made an app for showing bitmaps in bmpsuite.zip.
  Please see the PNG screenshot disguised in txt as attached.  All

 And yes, 32-bit bmp is a format i care a lot of since the loading is a
 lot faster.  :-)  On a platform with weak computing power, i have to
 save bits and pieces here and there.
 If there's no problem, please check my patch and correct it when you see fit.

 hmm well the text file attached corrupted - cant see it. but... i also created
 a mini image viewer too for this purpose. as such your patch will break
 transparent bmp's (100%) which is really an incorrect thing. if you can find a
 way to make it not incorrect - no problems. i really don't like the fix 
 because
 of its nature.

Well, that's what GIMP does.  I guess it's a workaround and it'll be
99.99% accurate since 100% transparent BMPs aren't exactly popular.
32-bit BMPs aren't popular either.  If my patch is not ok for the
upstream, I'll just keep it private.  I'm perfectly ok with it.


 but what i'm more concerned about is.. why are bmp's faster to load? really?
 seriously? you've tested? vs what other formats? i really didnt make any 
 effort
 to make the bmp loader fast. i just implemented it to follow the
 standards (that's why u find evas's bmp loader beat gqview by a large mile as
 the gtk one is enferior with standards support than evas's). when i do
 something i tend to like to do it right.


 now - you'll need to convince me much more that your hack is a valid patch as
 it really doesnt follow a standard. what is more of interest to me is the bmp
 loading being faster than... something else? what is that something else?

I haven't benchmarked BMP vs PNG loading speed with Evas.  The 'BMP is
faster to load' argument is based on various icon-loading (small 32x32
icons) tests I performed on my prior project (ARM920T device @400MHz),
which uses SDL/SDL_Image.  I think Evas is smarter with images but I
just assume loading/render of raw data (BMP) would be faster than with
compressed PNG files.

 sure - though it's once thing being a paining program (gimp) and getting a bmp
 load of a totally blank bmp wrong and being a generic library that loads
 images generically for any purpose. gimp can afford to get it wrong without
 much hassle - it's a bigger problem for evas to get it wrong as the intended
 usage is much less clearly defined :)

OK.  That's a sane argument.
Please note that Evas does not load 32-bit BMP with non-opaque pixels
created by GIMP properly.  I guess GIMP just creates those based on a
standard with added flavors.  By the way, SDL_image loads those just
fine (Evas also beats it on compatibilities too).

If I ever have time and come up with a patch that does not break 100%
transparent 32-bit BMPs, I'll let the list know. :-)

 well that depends. you pay a decompress cost - cpu time, but uncompressed 
 (raw)
 images you pay an IO cost. so which is worse. load 50kb from flash and spend
 cpu time decompressing... or load 200kb from flash and spend no cpu time
 decompressing. also with png you can select your compression level and tune
 things. i suggest you do some actual examining of this with your current
 target and try png's with various compression levels. you also can use eet 
 to
 store images (all even in a single file) and then use lossy or lossless
 compression, as well as zero compression (raw argb). so if performance is an
 issue - bmp isnt your only option. other formats give you a wider choice.

On my device and based on my experiments, raw data I/O beats
compressed data I/O + decompression.  Of course, it doesn't apply to
all platforms with different I/O performance and computing power.

Just for the record, I'm not saying BMP offers a _huge_ performance gain.

I'll try to find time and play with different formats. and thanks for
the eet tip.  I'll see if that causes any problem with my icon/UI
artist. :-)

 Hello Tom,

 Thanks for looking into this problem.

 Is r50887 fresh enough?  r50887 is what I first tried and failed.
 I reverted evas to r50594 and r50595 (while all other EFL libraries
 stay at r50887) to confirm it's the r50595 commit the causes this
 problem.
 METRIC_CACHE and WORD_CACHE are not enabled in all cases (they're
 disabled by default, I believe).

 I am not sure if you performed the same test I did.  If you use the
 source code attached previously, you have to click on elm_entry and
 check the stdout output (preferably with gdb to show the returned
 strings in bytes).

 It seems I didn't perform the same test, mind explaining exactly what
 you did? I just tried entering chinese characters and saw everything is
 fine. :)

Hello Tom,

Please use the test source code I previously attached.
** Within the elm_entry object (three chinese characters in the front,
followed by some english letters), click with your mouse on any of the
chinese characters at the start of the string and check stdout.  There
are garbage characters returned.

I guess the problem is somehow with the usage of Eina_Unicode.  Are
Eina_Unicode strings the same as the usual UTF-8 strings?  Please find
below the backtrace of gdb (r50595 evas) for your investigation.  The
new evas_common_font_query_char_at_coords() returns the INDEX of the
CHARACTER, while the old evas_common_font_query_text_at_pos() returns
the INDEX of the BYTE of the start of the character.  This returned
value is kept as _Evas_Textblock_Cursor's pos.  Does 'pos' mean the
number of bytes into the string or the number of character into the
string?  I guess the recent discussion of the docs would help here.

 I will, terribly busy ATM :P (I need to finish the textblock overhaul
 until tomorrow).

That's ok. :-)


 I guess the problem is somehow with the usage of Eina_Unicode.  Are

 No, as stated in the Eina_Unicode docs, Eina_Unicode are unicode code

OK.

 Yes, but this is ok because we now handle it as an index, and not a byte
 index.

OK.


   Ths returned value is kept as _Evas_Textblock_Cursor's pos.  Does 'pos' 
 mean the
 number of bytes into the string or the number of character into the

 As said, it's ok, because I also changed textblock to conform with that
 change.

OK.  Is Edje handling strings in UTF-8 or Eina_Unicode/Unicode?  It
seems to be using utf8 seems the use of Eina_Unicode does not exit in
Edje code.  However, it passes the cursor position (CHARACTER index)
to evas_string_char_next_get()...

Please find below the gdb backtrace.

In Frame #1, the 'pos' argument to evas_string_char_next_get() is the
CHARACTER index, which is then passed onto
evas_common_encoding_utf8_get_next() in 'iindex', which seems to be
used as the BYTE index.  The usage of the cursor position as the
CHARACTER index and BYTE index seems to be mixed up.

Maybe in Frame #2, _edje_entry_cursor_content_get() should call a
different evas API to reflect the string is in utf8 and pos is in
CHARACTERS?

 Hi all,

 Although the commit (and log) gives enough information by itself, I
 decided to write this post to further clarify the subject.

 This commit changed the font engine, textblock object and text object to
 use Eina_Unicode instead of utf8 internally. This commit does not affect
 API in any way (except for engine writing API which is pretty internal).
 There are a couple of reasons for this commit:
 1. With utf8 you can't jump to specific string indexes for example: the
 4th letter of a string.
 2. All the internal font functions already work with Unicode code
 points, so we had to convert encodings all the time.
 3. The BiDi algorithm in general and fribidi in specific, require the
 text to be encoded in Unicode because jumping between text positions,
 resolving visual-logical indexes and reordering letters are pretty
 common there.
 4. This cleaned the code quite a lot, because retrieving specific
 indexes was now made easier.

 In this commit I also started relying on the new FriBiDi version
 (0.19.2 which was released an year and a half ago) as implied in my
 previous mail about BiDi.

 This commit also includes a bit of renaming, evas_intl_* got renamed to
 evas_bidi_*, evas_common_font_utf8_* got renamed to
 evas_common_encoding_utf8_* (the previous ones still exist but marked as
 deprecated).

 Currently, the changes I did in the font engine are pretty clean, though
 I can't say same about the textblock object. In the textblock object I
 still do stuff as if the string is stored in utf8, that is, I still kept
 the current design and didn't do any major changes (that change flow too
 dramatically). The code works, and it's not uglier than it was, it's
 just not a clean as it will be once I get over with it. I had to commit
 now in order to allow raster to uncrustify everything, let other
 people continue to work on other parts of Evas without a merging hell,
 and because it's better than how it was.

 I will overhaul the textblock object in the following weeks (hopefully
 will do a small API breaking commit tomorrow in order to make get it in
 efl 1.0) and after that will redesign textblock to work more naturally
 with unicode.

 I did a lot of testing, but I still can't be sure everything works ok,
 to me it seemed that everything is exactly as it was except for the bugs
 I fixed. If you find anything fishy, please let me know. Sorry for the
 big commit, but it includes many interdependent changes. It's also time
 to mention I did *not* test on Mac OS/Windows/Exotic engines, although I
 did modify the code where needed, I can't assure it works there, so
 again, if you find anything, drop me an email.

 If you have any questions, please let me know,
 Tom.

Hello Tom,

I can confirm this commit breaks evas text handling for Chinese characters.
Please find the attached file for reproducing the problem.

I reverted evas to r50594 and elm_entry_cursor_content_get() works properly.
Then I tried r50595 evas, which is this svn commit, it fails.  Chinese
characters are returned with garbage bytes appended.
Any ideas what went wrong?  I am happy to help test more.

Thanks.


brian

 I found a bit of spare time, tried it here, and it looks like it works
 (latest rev,not the one you mentioned,
 and it makes sense, since there were fixes added especially if you used
 word/metric caches).
 I can only verify it works to some extent, I see white squares (chinese
 fonts did not get detected
 here for some reason, not sure if I even have them) which is what expected,
 no garbage added.

Hello Tom,

Thanks for looking into this problem.

Is r50887 fresh enough?  r50887 is what I first tried and failed.
I reverted evas to r50594 and r50595 (while all other EFL libraries
stay at r50887) to confirm it's the r50595 commit the causes this
problem.
METRIC_CACHE and WORD_CACHE are not enabled in all cases (they're
disabled by default, I believe).

I am not sure if you performed the same test I did.  If you use the
source code attached previously, you have to click on elm_entry and
check the stdout output (preferably with gdb to show the returned
strings in bytes).


 I suggest you try later revs just to make sure it's not something fixed in a
 later commit.

See above.

 Tom.

[E-devel] Question: how to force using bitmap fonts when the font size if smaller than NN?

[Brian Wang]

Hello all,

For Chinese characters, small text looks bad with all those
anti-aliasing edges and it affects readability of the text.  How do I
make sure that Evas/Edje/Elementary uses bitmap fonts when the font
size is small and uses scalable fonts when the font size is larger?

Or is it a font setup problem?

I just put my Chinese bitmaps fonts (*.pcf) on my device and Evas is
complaining NOT SCALABLE! a lot and text becomes 'invisible'.

Thanks in advance.

Re: [E-devel] [PATCH] evas BMP loader - fix for 32-bit BMP files saved by GIMP

I have tested the broken image.  I guess you mean they're invisible
with my patch?
GIMP can load them correctly.  I briefly browsed GIMP's bmp plug-in
code but could not find how it determines the correct alpha mask for
32-bit BMP.  I could not find relevant specification about ARGB 32-bit
BMP in BMP v3 specification.  Without proper reference, I can only
come up with a workaround...  Any BMP wizards here?

However, I think the attached patch does the trick.  It first sets
hasa flag and if all pixels are transparent (I guess it's an
uninteresting/useless image if the user can't see any pixel of it), it
set the Image_Entry's alpha flag to zero.

g32def.bmp, g32bf.bmp and the attached Icon.bmp can all be loaded
properly.  Any more interesting BMPs?  :-)

Thanks for looking into this.


brian


 Hello all,

 GIMP (2.6.8) seems to save 32-bit BMP in the Windows 3.0 + (v3)
 format mentioned in evas_image_load_bmp.c.
 I'm not sure if the patch breaks anything (or images created by other
 tools).  Please correct it if you see fit.
 This patch should enable support for ARGB BMP files for evas.  It's
 tested on my x86 box.

 Cheers,


 brian
