Dear anthony,
thanks for your little lesson to become a good programmer :P
my needed code
echo system("$IM_CONVERT -font includes/arial.ttf -fill none -stroke white
-pointsize 28 -draw 'gravity center rotate -45 text 0,0
\"$COPYRIGHTTEXT\"' -resize $GENERALSIZE $IM_JPG_Q80 $filename $PICNAME");
i have found your examples before you replay my question... i wrote i have
search a lot for some example, later i have found your great example site,
you have do a great work there. that what i wanted before. just an example
site. but in your answer you told nothing about your example site ?
and my if i have can a wish ... was like the google i feel luck today...
button :)

When starting out in any API, it is best to start with a simple trival
case.
I would look for a simple load and save image API example. Examine it
and then try to fit the various operations you want to perform into
that.
Actually if you are a reasonable programmer I would first start with
a command line version, then do to Perl or PHP, and finally work my way
down to C. You get a real good understanding of the librarys and thw
way things are done by doing that.
If you can't find a specific function in the manuals (or source) then
you can ask the specific question to the email list and IM forums, but
a general one like what you asked, which basicaly requests a final
version, is likely to be ignored, as few have the time to do all the
work.

Nope, it still doesn't work.
PNG8 supports partial transparency (and has for a while). Internet
Explorer only supports PNG8 boolean transparency, though. This has
lead to limited use of partial transparency on the web.
A quick google search pulled up this bug from a while ago:
http://studio.imagemagick.org/pipermail/magick-bugs/2003-September/

I wonder if it's the same problem.

Well, I'm not here to tell you guys how to implement your PNG8
support, but from the looks of it, you may be falling behind.
It looks like PNG8 partial transparency is part of the spec. From
http://www.libpng.org/pub/png/pngstatus.html :
"Many applications now support both basic GIF-like transparency
(palette-based with a single, fully transparent color index) and full
alpha transparency (32-bit RGBA); a handful also support PNG's "RGBA
palette" mode (8-bit with a multi-entry tRNS chunk)."
Example images are on this page:
http://www.libpng.org/pub/png/pngs-img.html
And it *even* looks like IE7 will be supporting PNG8 partial
transparency. See screen shots of previous page here:
http://www.libpng.org/pub/png/pngs-img-ie7w32.html
For more technical info, see here:
http://www.libpng.org/pub/png/book/chapter08.html#INDEX-618
As far as my "bug" goes: I just tried saving as a 24 bit PNG from
montage, then using pngquant to reduce the colors, and it worked
fine. I have the transparency like I wanted, with the palette I
wanted. Hopefully pngquant will also be able to handle my large (4 GB
uncompressed) images, but it will be a number of hours before I can
test that.
Maybe you should take a look at the pngquant source for quantization
algorithm ideas?

It could very well be.
IM png8: is by defination the same pallette structure as GIF.
and so isn't incorrect in IM terms.
Prehaps a png8t: format is needed for a 8 bit pallet with partical
colors.
Their was some recent work done with color distances last March so
that
all pure transparency colors are of disance zero. This was needed for
layer optimizations as without it a near transparent colors can be
very
distant from each other, distorting color reduction and other color
tests (EG -fuzz color matching stuffs up badly)
This is a linear adjustment as such the RGBA distance between
half-transparent red to half-transparent blue is half the ditance of a
fully opaque red and blue distance.
Hmm my auto sinature picker picked a good on for this topic!

Hi, I'm not sure if this is a bug or if I did something wrong.
I can successfuly build configure.sln in .Net 2003. However, when I try to
finish the Visual Magick configuration, it gives me this error:

This is wierd! I just downloaded Windows source distribution for 6.2.7
(over 5500 files), and I couldn't find a file called thrdcore.cpp.
Does anybody know where the file comes from?

Hi
I think it's MFC CWinThread source file.
Check in MS VC MFC sources (I have VC++ version 6, so I can't tell you exact
line),
it looks like:
ASSERT_VALID(pThread);
or
ASSERT(pfnThreadProc != NULL);
in VC++6.

To: <[email protected]>
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset="iso-8859-1"
Hi
I ve to create an outline text with ImageMagick. So I ve used -stroke,
-strokewidth and -fill options to do the same. I m able to create the
outline text image by providing color names to fill and stroke options like
red,blue,green etc. What I want is provide the RGB combination to do the
same......like rgb(255,0,255) or hex equivalent like #ffff00.
Is there any way I can do it.
My cmmand is as under.....
convert -size 300x100 xc:transparent -font Arial -pointsize 25 -fill white
-stroke black -strokewidth 2 -annotate +20+50 'Test Message' convert_img.png
Plz help

Did you try:
convert -size 300x100 xc:transparent -font Arial -pointsize 25 -fill
"rgb(255,255,255)" -stroke "rgb(0,0,0)" -strokewidth 2 -annotate
