[Gimp-developer] Scaling Plugin (This is not what you think!)

2007-09-07 Thread Campbell Barton
Hey. has anyone seen this?
http://www.youtube.com/watch?v=c-SSu3tJ3ns

Its an interesting method that attempts to move elements in the image 
without scaling them so you can resize the canvas have a quick look 
at the video to get the idea.

BeBraw is working on a plugin for blender3d that does this but thaught 
you might be interested. Once his finished maybe it can be ported to 
gimp (blender is in C so might not be t hard)

Id like to see this followed more strictly. people who post feature

These seems to be tension between developers and users who want to 
influence the development direction of the gimp.

This adds a fair bit of noise to the list and means the quality of 
discussion is lower with interjections by people who are not developers 
and dont appreciate the purpose of the list.

Im not a gimp developer so I cant speak for you guys, but from my 
involvement in other open source projects and reading development 
mailing lists, this problem is especially bad here.



for Blender3d we have a Blender functionality list, since discussing 
improvements to software isnt exactly a user issue either.

features can be kicked out on this list and suggestions made be

 Hi Sven,
 
 Isn't there a way on the channels (IRC, bugtracker, mailing list) to 
 simply restrain the access to a specific individual when things get to a 
 point where repetitive demands and persuasion don't seem to give any 
 results?
 
 Let's face it, I realize this is pretty unusual and must very rarely 
 happen but there is a possibility that someone else steps in one day 
 with the same behavior. While there are of course no ways to prevent 
 this upstream can we at least make sure there are ways to prevent this 
 person from being in contact with the community once the problem has 
 been clearly identified?
 
 I really wish we can sort this out because this might happen elsewhere 
 in any other project. It is not an exclusivity of the gimp team!

 Sven

 From my experience in a few OSS community's, this would seem to be a 
fairly rare incident.

Some developers can probably come over snobby or arrogant but to be 
abusive (thats what I gather has happened) is something I havnt seen before.

If I ever acted in a way that hurt the Blender3D community, I would be 
kicked out before I did too much damage.
Its most surprising this behavior has been this tolerated for so long.

Since carol had the composure to be civil with people face-to-face makes 
me think that she does KNOW BETTER... and that her behavior is something 
she allows herself online where one can have less inhabitation's saying 
offensive stuff.

Its not like you are being unreasonable, Sven has said he wanted the old 
Carol back and if one day Carol decides she is ready to come back into 
the community - She could could earn back some respect and contribute again.

I have know people to go through mental illness and have sympathy for 
her if this is the case, but that dosnt mean you let her hurt a project 
thats important to many people and the linux community at large.

Re: [Gimp-developer] Blur tool darkens image?

2007-04-24 Thread Campbell Barton
just did a simple test

* 16x16 rgb image
* select half (vertically in my case) and fill in
* run the Gaussian blur, 1 blur pixel
* Hold  Ctrl+F to rerun the filter many times

- Image will eventually turn black
- Happens for RLE and IIR

If its a rounding error, you could see if theres some way to give a more 
accurate result (cast to float?) - you probably alredy do that..

At worst, you could dither so every second pixel rounds up.

 Your video shows the blur tool being used on large areas of black color
 and small areas of white color. The average of this is a dark gray. Now
 when you continue to blur, you are mixing a dark gray with black. If you
 go further, you end up with all black.

 But there could very well be rounding errors in the blur tool code.
 There are even most definitely rounding errors as we are only working
 with 8bit per channel and rounding errors are unavoidable then. But
 please take a look at the code and see if there's anything we could
 change to improve this.


 Sven
 
 Jasper , your bug says:
 
 It's algorithm
 appears to favour dark colours when they are included in the blur.
 
 Why do you say that? Does it still favour dark colours if the image is  
 predominantly white?
 
 From my understanding, the average lightness of a given image should  
 always
 remain constant as it is blurred.
 
 What is your understanding , of what blur tool?
 Is there some specific blur algorithm that you believe does preserve  
 lightness or is this just an assumption you were making?
 
 Maybe you could be more precise about what blur you are refering to ,  
 there are several IIRC.
 
 Please try to be a little more specific about what you are reporting.
 
 Thanks.

I see where your coming from, we have a similar problem maintaining 
Blender/Python Scripts -

Could the Verse plugin be added after the next stable release, and its 
author given commit rights if his changes/code is good quality. - If the 
author dosnt maintain it or there are problems that dont get resolved it 
cant be removed before a Gimp stable release.
This way, you dont need to suffer an unmaintained plugin and your have 
the possibility of an extra contributer to the gimp.

 What's the problem with the plug-in being distributed seperately? For
 one, this plug-in is not useful for most of our users, it would just
 clutter the menus for them. But more importantly, we don't have the
 developer resources to maintain even more plug-ins. The plug-in seems to
 be well maintained outside the source tree. Write the author a mail and
 encourage him to continue doing so.

Hey, is it ok to report bugs her?
With Blender3D we sometimes report bugs on the ML if the features are in

It is actually too early to report any bugs in the new tool. It has only
just been merged into the HEAD branch and a lot will change before it
starts to make sense to report bugs for it. Mentioning problems on the
mailing-list is OK though as it doesn't create as much hassle as a bug
report in the bug tracker does.

  
The perspective clone tool crashes if you make the perspective square 
concave or a 'bow tie' where 2 of the lines intersect.


This also locked X11 after crashing, tho thats another issue,



Why is that another issue? GIMP crashes while the pointer is grabbed and
it needs to do that while you drag the perspective plane around.


Sven

  


On the last point,

previously I mentioned Gimp stealing the mouse focus, causing me to kill 
X even though other X application were responsive.


This happened again with the perspective tool, if it had crashed and 
closed it would have been ok, but in this case it gave the [segfault 
error, continue, exit... etc] in the command line prompting me for 
input, but the input being locked didnt let me enter in a value.


I mean to say that a tool crashing and the tools locking the input are 
seperate issues.- its not the perspective-clone tools fault X11 is 
locked. ;-)

[Gimp-developer] healing brush hanging X11

2006-09-04 Thread Campbell Barton

Hey,
Just tried the healing brush for the first time, on an 8mp image with a 
200px brush.

- Useually works ok for most tools.

With the healing brush it was very slow, thats ok too- I assume theres a 
lot of math to go for this tool


But after a click+drag it was so slow, it would not finish after about 
2min... even worse, I could not move any windows or click anywhere while 
it was thinking.


Only quick way out  was to kill X11 with a ctrl+alt+backspace. (or boot 
up another PC and kill the gimp via SSH)


it looks like this is more of a problem with the way gimp locks X11 then 
the healing tool its self.

IMHO, Gimp Should probably change its name, though I have no strong 
feelings on the matter, kind of like the name since I have used it for 
so long it has no negative associations.
I WOULD - say I use the Gimp on my CV, but not like... I use Linux, 
Blender3D and the Gimp
just say... I use Linux, Blender3D and the Gimp Image Editor, If you 
are obviously serious in other areas then theres no reason for people to 
think your being Rude.
If the job dosent require image editing then perhaps leave it off for 
shallow minded HR, Im guessing the Gimp is American? (Pulp Fiction) - In 
Europe/Australia it might not be seen so badly.

Re: [Gimp-developer] gimp with large files. test.

It is only possible by recompiling all of GIMP and you end up with a
version of GIMP that writes incompatible XCF files and cannot read the
XCF files written by a version of GIMP compiled with a different tile
size. I have done this at some point and did some tests. I had the
impression that using a larger tile size doesn't make any noticable
performance difference.

If someone wants to rewrite the XCF routines so that tiles are always
written and read with a size of 64. no matter what the native tile
size is, we could make the tile-size configurable. But I am not sure
if that's worth the effort.

  

On the other hand, Photoshop may be working on a smaller copy of the
image at 1:1, has this been considered by the gimp dev's?



Yes, this has been considered and for the color correction tools, it
would actually be a good idea. But as far as I know, no attempt has
been made to actually implement this.

Gimp CVS as of today and Photoshop 7 under wine.

* Painting with an 1000 size brush, both performed about the same on both.
* Curves was much faster on photoshop.

I tried gimp and photoshop with nice -20, highest priority) -
Gimp was noticable faster..
Photoshop didnt make much difference, (not sure how wine handels nice)

Invalid?
Well photoshop 7 runs fast in wine. fast enough that it even 
significantly out performs gimp in areas.
there are even a number of benchmarks showing wine to be faster then XP 
on the same PC. winning about half the tests thrown at it.


There not exact benchmarks, but they indicate that Photoshop uses 
different methods then the gimp to operate on images.


EG. If painting in both apps are about the same for painting on a 
8000x8000 image.

you can assume they use a roughly similar painting method.

if Curves on Phoposhop is instant, and takes 3 second on the gimp. then 
photoshops doing somthing gimp isnt.


Also, a lot of people are interested in an image editor for Linux- 
Photoshop+Wine is that. (albeit X86 only)

[Gimp-developer] Accepting GSOC Students

2006-04-20 Thread Campbell Barton
Hi, with Blender3D we did GSOC last year and I was a mentor for one of 
the projects.

Some decisions have been made this year as to how we filter applicants.

in a nutshell- these seem obvious.

  1. They must be able to compile the software   (a few students ended
 loosing time by not having a propper dev environment)
  2. They must be able to submit a patch-(for blender, we are even
 requiring they write a small patch and submit, as a requirement
 for being an applicant )
  3. They have to know the language they are programming in.   (durr.
 but we had 1 guy who hadnt used C before, he had used other
 languages tho and did complete the project, but this is not ideal)
  4. Must be able to devote full time. no summer jobs, courses.   (had
 some problems with this also)

for full docs see.
http://mediawiki.blender.org/index.php/BlenderDev/SOC_2006_ideas


I hope gimp can get gsoc, no doubt many of the guys at google even use

Re: [Gimp-developer] Smaller toolbar and grouping

2006-04-01 Thread Campbell Barton

Hey Bart.. Another Blender3D person here!

As far as useability, goes- im that That fussed. though I tend towards 
the more common row of buttons under the button your pressing (alligned 
to the right/left)
This is simple because your not limited to a 4 options. (okay 5 would 
work but look silly) and since a diagonal button is not a part of the 
options but still outlined somewhat, (in barts example the measurement 
tool is outlined on 3 sides, though I can tell its not an option, a 
quick click and select may be more confusing in this case.)

its better to just have a row//

Another resion to use a left/right aligned row. is that many people 
place there toolbars at the side of there screen. no5. would have the 
LHS button off the screen.


Still I like the idea of having nested buttons, especialy for the 
transform tools that I rarely use but need to access.

However, from a usability standpoint it might be much harder to use

There could be an argument for it becoming second nature, like

Hah. your right. its not exactly logical. but its a tradeoff
Toolbox File-Extensions (uses a word people can understand)
Toolbox Xtns  (Is in a place people see)

if you want to be picky- Preferences is not a file operation either.  
But there is no Edit, Options, Settings, Tools menu on the 
toolbox to place it.

How many times will it take before people realize how much work it

It's simply not worth it, especially since it is a widely accepted
fact in user interface design that such modes are a bad idea.

We can improve the GIMP UI and it will improve. But if you really
think that the only acceptable user interface is a perfect clone of
Photoshop, then why don't you go ahead and start a project that aims
to create such a clone?



I am primarily a KDE hacker. I already donate piles of time to that effort, 
including writing docs. I use Gimp almost every day, but I hear it 
continuously about the need to have it at least have a PS compatibility mode, 
from graphic designers who would love to use it.

2006-03-21 Thread Campbell Barton

This is one of those debates which dosent thrill me.

Gimp != Photoshop.
People often misunderstand free software and think.
 Hey here is a free Photoshop, cool. What?? its not the same... 
why not???


People open the gimp. poke about. and complain if its not what there 
used to. *(Grrr)


I dont have much time for these people, because they obviously are not 
using the Gimp long enough to appreciate its advantages over photoshop.


The UI is important, but its only 1 aspect of a program.

Somthing people dont focus on as much is the application work-flow. 
which I feel is more important in the long run. (ok the UI has to work 
of course)


Basicly - Once you know where all the buttons are, how efficently can 
you get the job done?
- In my experience, The Gimps workflow is very nice, I have no 
complaints. so it always baffels me when people complain about the gimp 
not being like photoshop.



I use Blender3d every day and the gimp most days also for work as a 3d 
modeler.
Blender is more extreme in that its UI is not that good, but it has an 
excellent work flow.


In some ways its better to be different. - Because its very unique, we 
rarely get the   Why dont you work like 3dsMax?? posts anymore...

viva la difference!

2006-03-02 Thread Campbell Barton


Hey Gimp dev's (by the way, how many gimp dev's are there?)

it often annoys me that people value a program based on its support for 
a foreign format.
PS Dev's dont waist time supporting other apps so why should we? (I 
know, cos Gimp isnt the standard :/ )


As said afore, Im realy happy with the gimps direction, and have enjoyed 
using since 1999, and even use for commercial 3d projects now.


Supporting stuff like layer effects is okay, but Im guessing its not a 
small task...


BTW- One feature Id be interested in seeing is layers with linked bitmap 
data, so you could move thenm about but theyd share pixel info. have 
been in a number of situations whis would be nifty, also cut down filesize.

Like M$ Word for text the Adobe Photoshop is a standard app for creating
graphics (nearly 80% of all creatives use it). Gimp is a great
application too but working together with others a much improved PSD
support is needed:

- Gimp did not recognized which layers of the PSD visible or not and
show allways all layers
- if possible it would be cool if Layer-Effects could be converted to
Layers
- Text should be editable Text and  not just pixels
- May if Gimp supports one time herachies of layers it woulb be nice if
Gimp could support them too

this task at openusabilit.org (see

the subject.  It would certainly help to have a professional on board.

One of the projects that we started recently is trying to come up with
a collection of personas that represent GIMP user groups:

Since you seem to be working in Berlin, perhaps you want to join us at

I know you probably want an sdk that can handle images bigger then your

Large images + Low Ram + Fast editing just isnt that possible- unless 
the operations can be edited on tiles as you suggest. not all func's can 
be tiled, so probably to save your self some time - buy a 1gig chip.

[Gimp-developer] Idea for syck image on disk.

2005-06-09 Thread Campbell Barton

Hi, A while back I tried out a plugin for the gimp called Gimp-Verse
For those of you who dont know about verse, its a way to collaberate on 
multimedia/3d projects transparently over a network..
This plugin allowed the Gimp to edit data and have it visible in 3d over 
a network realtime.

See- to get the idea
http://users.pandora.be/blendix/verse/old/verse_gimp_blender_demo.png

Anyhow, I tried to get this working but compiler issues various other 
things stoped me from getting verse-gimp up and running.


I ended up with a very hackish solution that involved taking screenshots 
of the Gimps image window and reloading the file in Blender (3d 
application) 10 times a second, but this is far from Ideal.



A Nice inbetween solution would be to have some plugin that stored an 
image's tile cache as a flat image file (bmp/tif any format would do)
WHen the tile cache was updated, the image would be updated on the hard 
disk.
There would be lots of other issues to deal with- Like which resolution 
of tile cache to use, but Basicly All Im interested in is an updated 
image- Even if it changes to match teh view resolution, or some parts 
dont update of there off screen..


This would allow editing in a 3d application and painting at the same 
time which is very usefull.


Any suggestions?

Oh, by the way, only basic C coding experience, good with Python tho.

[Gimp-developer] Magic Wand idea~

2005-01-23 Thread Campbell Barton
Hi All, Just thinking about enhancements to the selection tool
I had in idea how to make the magic want very usefull in some situations.
When your selecting an area from a photo there is often natural specs or 
tiny dots, sometimes covering an entire image -
I was thinking of this when editing saterlite data..

Anyway, These specs are not selected with the body of colour and it 
becomes necessary to Manually
1) Select them with the lassoo (uses too much time)
2) Add them to the selection (Often select too much of other areas you 
want unselected)

A solution would be an Ignore Pixel Island option.
With a slider Pixel Area
... Mabe Bottleneck px length??, probably more complex to code.
This way you could still have pixel islands but ignore tiny stratches etc,
I like this because it would not have a filtered affect, just a 
threshold for small pixel islands,
This could also be added as an option to Colour select and would be 
usefull here too,

[Gimp-developer] Preview bug in all filter previews.

2004-11-08 Thread Campbell Barton
I small bug ois that the selected channels are ignored when makinf the 
preview.
- Try only select the red channel of an image and then apply a gausian blur

*The preview shows blur for all channels
*The result is only on the red channel-
Somtimes I only want to blur a channel so the preview isnt correct in 
these situations.

Its obviously less processing to compute the plugin on less chanels so I 
think this should be added.

[Gimp-developer] Gimp development

2004-10-11 Thread Campbell Barton
Hi, My names is Cam- I have been involved in Blender3D Plugin writing 
and development for a while now and have a little experience in C.
I use the gimp every day for imaging and texturing for 3D models.

Blender.org is realy good with its community, and web forum- I didnt 
find anything like this for the Gimp- (Not saying it isnt there),
Now Im on this list Id like to be involved with writing Plugins and a 
little C where I can.

Some things Id like to know tho are-
Is there any 'good place to start' with C programming in the Gimp. - 
Docs tutorials etc. (I have mainly used OpenGL in C/Python)

Is the Gimp serious about Python as a plugin language, from using 
Blender3D/Python, Gimp/Python would be easy- but I tried and couldent 
get a Scheme script running in python- (Could have been a silly mistake 
but I tried for ages)

Is there a way of refreshing python scripts without restarting??.
Im thinking I should probably just go wuith scheme since its the 
default... but Id liek some feedback on this one.
