Re: [Gimp-user] How to create jpeg files compatible with a sony

2005-12-04 Thread William Skaggs

The jpeg files that GIMP creates are perfectly valid.  I think
the basic problem is that you are trying to use a camera as a
storage device, which is not its intended purpose.  There are
some cameras that, when you take a picture, create a digital
watermark that the camera can use to tell if the file has
been altered or corrupted.  If the watermark does not match
the data -- which is bound to happen after editing in GIMP, 
because GIMP does not know about watermarks -- then the 
camera may treat the file as invalid and refuse to display it.

I should add that I'm going pretty far beyond my knowledge here. 
While I'm reasonably confident that this sort of digital watermarking
does exist, I am only speculating that this accounts for your
problems  -- particularly with the photo-printing service.

Best wishes,

 As for layer effects, well perhaps you should ask the users what it is

I think most of the developers already understand the value
of layer effects quite well.  Let me try to summarize the current
situation.  There are basically two possible ways of proceeding.
One is to add layer effects onto the current GIMP architecture,
which could be done, but in a somewhat hackish and ugly way.
The other is to defer them until the arrival of the long-planned
GEGL-based architecture, which will make layer effects and many
other nice things easy and natural to implement.  The decision
has been to wait for GEGL.  Whether this is the correct strategy
can be debated, but it definitely doesn't mean that we don't
care about layer effects.

 This is not at all about filetype association. GIMP help calls the
 default web browser, so that's what you should be looking for. It
 appears that Crimson is set to be the default browser on your system.

Actually this is not quite correct.  GIMP simply tells Windows to 
open the url, it does not specify that a web browser should be
used.  Now, if the url had an extension of .html, then the system
default browser would be used unless some other handler had been
associated with the .html extension.  But in many cases the url's used by
the help system are more complicated, e.g. ch03.html#gimp-tool-options-save.
It is not clear how Windows will react when asked to open such
a thing.

Over the past few days I've coded up a new interface for the rect

Sven wrote:
 I don't know who's feeding you your information but
 that person is highly misinformed since there are no vector layers.
 If you want postscript or even pdf files using vectors instead of
 bitmaps, you are looking at the wrong application. GIMP is an image
 manipulation program for editing raster graphics. If you want to edit
 vectors, please use a vector editing application. 

The Gfig plugin now creates its own layers, and they are vector layers
because if you run Gfig with the active layer being a Gfig layer, you
can manipulate the objects there as vector objects.  Dave Neary's GIMP 2.2
headlines mention this, with perhaps a bit more enthusiasm than is 
entirely justified -- this is presumably the source of the misinformation.
In any case, the capabilities of Gfig are quite primitive in comparison with 
well-developed vector graphics programs such as Sodipodi or Inkscape -- and 
strictly speaking, the functionality does not come from GIMP itself but rather 
from the plugin.  The rest of what you wrote I think is quite correct.

It may be interesting to note that it would theoretically be possible
to modify programs such as Inkscape or Sodipodi so that they would
be capable of running as GIMP plugins, creating their own special
layers and storing their data as layer attachments (i.e., parasites
in GIMP terminology), in the same way that Gfig now does.  (This is
also basically how the Text tool works, except it doesn't use parasites.)
Such an approach could give GIMP full-powered SVG-vector-editing
capabilities without requiring any major changes in the GIMP core.

Re: [Gimp-user] dpi from 75 - 300 ??

2004-09-13 Thread William Skaggs

Geoffrey wrote:
 So here's a question which will demonstrate my ignorance.  I've got some
 digital photos I took that, when opened with GIMP are identified as
 being 75dpi x72dpi.  I need images that are 300 dpi, so is it possible
 to convert the 75dpi image to 300 dpi??  I selected to scale the image
 and happened to notice that I can make this change at this point.  Is
 this doing what I'm expecting?

That is a question that only a mind reader can answer.  (Sorry :-))

Here's the thing:  a resolution in dpi is not a property of the image
per se, it's a property of the way the image is displayed, on the
screen or on paper.  When you see a resolution of 72x72 dpi for an
image, what those numbers represent is somebody's judgement that the
image will look good when displayed with 72 pixels per inch; and 
usually this means look good when displayed on a monitor, because
nothing looks very good when it is printed at 72 dots per inch.

Now suppose you have a 300 x 300 pixel image, with a nominal resolution
of 72 dpi, and suppose you want to convert it to 300 dpi for printing.
There are two approaches you could take.  (Actually more, but let's keep
it simple for the moment.)

(1) You caould say, okay, 300 pixels is about 4 inches at 72 dpi.  I
want my print to have the same size.  So, I will scale the image
to 1200 x 1200 pixels, and set the resolution to 300 dpi.

(2) You could say, okay, I don't want to make the image look blurry
by scaling up the number of pixels, so I will simply set the resolution
to 300 dpi without changing the pixel dimensions, thereby getting a
print about 1 inch across.

Both of these are legitimate choices, and so are many others.  The best
way to do it depends on your image and your printer.  What makes it
complicated is the fact that printer dots have much poorer color resolution
than monitor dots.  On most modern systems, a monitor dot encodes 24 bits
of color information.  On a typical high-quality printer, a single dot encodes
about 6 bits of color information.  Thus, simply changing the resolution so
that a single monitor dot becomes a single printer dot is usually not the
best thing to do.

Assigning one of 300 dpi is simply arbitrary.  A resolution only
exists when an image is physically displayed, on a monitor or paper.
The 300 dpi value is simply a recommendation of a resolution that
will give a decent-looking result when used for printing the image.

Anyway, the main reason GIMP does not show you the resolution is 
because it is stored in the EXIF data, and GIMP does not currently
read EXIF data, it simply passes it through unchanged.

 GIMP 2.0.3 Win32 

Yes, you are right that it does not work:  this is one of the
main reasons why Gimp 2.0.4 is going to be released very soon --
in the next few days.  It worked in 2.0.2, and it will work again
in 2.0.4.  See http://bugzilla.gnome.org/show_bug.cgi?id=148632
for more information.

Re: [Gimp-user] Invisible selection marching ant

 about this ?

This is kind of an annoying answer, but it is possible by playing
with display filters (View-Display Filters) to make the outline
visible in the cases where it normally isn't.  (This has no effect
on your image, and can be turned off when you don't need it 
anymore.)

Incidentally, this problem has nothing to do with marching ants --
the marching ants only appear after the selection is completed,
and they show up fine.

Anyway, this is a problem that if it were considered important
would not really be that hard to solve, but nobody has ever
considered it important enough to spend serious time on.

You didn't give enough information about your system for me to
be sure, but I bet you are seeing the bug described by the
following two URLs (which also tell you what to do about it):

http://gug.sunsite.dk/forum/?threadid=2009

http://bugzilla.gnome.org/show_bug.cgi?id=142252

Basically it is a problem with the library called libexif in
some recent SuSE OS's, and the solution is to replace libexif.

[Gimp-user] Re: how to change colors

2004-06-13 Thread William Skaggs


Rick Pasotto wrote:
 I have a fairly simple gif image that has various shades of 
 brown. I'd like to have the same image but with various shades 
 of grey instead.  What would be the easiest way of doing this? 
 Is there an algorithmic way of converting the brown range to a 
 grey range? Given that I could easily change the values in the 
 colormap. 

First, since you are a novice, I should probably tell you to
convert the image from Indexed type to RGB type, or you will
not be able to do very much with it.

After that, depending on exactly what is in the image there may
be easier ways than what I am about to describe, but I think for
a general solution you need to begin by creating a selection that
contains the parts of the image you want to modify.  Possibly the
Select by Color function will do this for you, or you may have
to do something more sophisticated.  

Once you have selected the parts you want to modify, the rest
is easy:  just activate the Hue-Saturation tool, and reduce
the saturation to zero.  Everything in the selection will then
turn to gray.

If this does not do what you want, please try to clarify the
problem.

 A while back there was a question on this list wheter or not it

 Unfortunately, I just re-installed my system, so I'm not sure where
 the mails about this went... I was therefor hoping that somemone
 could give me the URL for this tutorial -- and possibly give me tips
 about things to watch-out for when trying it with GIMP.

The archives of this list are available on the net, at:

Concerning the copyright question, the answer is that you would
not be breaking any copyright for PhotoShop per se, but you may
well be breaking copyright for the tutorial.  The only way to
tell is to read the copyright notice.  If you cannot find one,
then I suggest that you contact the author of the tutorial.

The Color to Alpha filter does exactly what you want -- access it using
the menu path Filters - Colors - Color to Alpha.

Thanks for the reminder.  Okay, I have uploaded the code to the

You should have a working gimptool-2.0 in order to install it.

[Gimp-user] Re: dynamic text glow, what happened to them?

2004-04-28 Thread William Skaggs

Dynamic text is no longer needed, because the things it did are 
now done by the regular text tool (and done a lot better, too!).

I don't know about the glow filter, but there are indeed some filters
that have not yet been ported from Gimp 1.2 to Gimp 2.0.

Re: [Gimp-user] gradient-blur

2004-03-24 Thread William Skaggs
For what it's worth, I went ahead and implemented a true variable blur filter,
by modifying the blur plug-in code from 2.0.  I'll put the code in the plug-in
registry after a little bug-fixing, but anyway, I put together a comparison of 
what you get with variable blurring versus what you get with variable blending
of blurred and sharp images -- you can see it at:

http://gug.sunsite.dk/pictures/1080149573.png

Please note that I am not saying that one is better than the other, just that they
are different.

 What is the best technique? What you suggest or the one that follows? Are
there any problems with these two ways, compared with the mod of the blur 
filter way?

Neither of these techniques work, as you will see if you try to apply them.
When you mix a blurred image with a sharp image, the result does not look like
a less-blurred image, it looks like a sharp image whose contrast has been reduced.

Re: [Gimp-user] gradient-blur

2004-03-20 Thread William Skaggs
Actually the reality is that Gimp, with the standard plug-ins, does not have the 
ability to do this, although there are ways to fake something that looks sort of 
like it.  The easiest way to get it would be to modify the blur filter (found in 
randomize.c in the plug-ins directory) so that the probability values are derived 
from a map-image rather than constant.  This would really be a valuable thing to have.
