I am using Imagemagick as installed in Ubuntu 11.10. When try to annotate with Thai characters in UTF-8 format the font does not render. I just get question marks instead. The font I specify is known to support Thai script in other applications. Can I remedy this by building IM from source?

Thanks,
Bob Parker

Perhaps IM is not seeing the font with the thai glyphs, or the Thai glyphs are not in UniCode positions
Use "-debug annotate" to see exact what font file is being used by IM.

I have replaced -annotate in the script with -debug annotate.
Tahoma font produces good results with Thai script in many applications.

Works fine for me!

Not certain about the added funny squiggle above the second letter though.

Ok thanks. So it looks like something is wrong with the Ubuntu build of it then.
I have tried the:
./configure
make && make install
on the source. It builds ok but all I end up with is a program that does nothing at all.
I suppose missing delegates.
Is there a list of possible libraries I can check out and download?
I've googled on this a bit and come up with tales of failure only.
BTW the funny squiggle over the text on your result is required to be there. It's a tone mark

I tried your command literally and I still just get question marks. Also I had to fully specify the location of the font because this Ubuntu version seems to have no idea of a font path.

There was a recent change where ImageMagick did some switch from using freetype libraries to pango But that should not effect things too much.

Have a look at the list of dependancies given on
http://www.imagemagick.org/Usage/api/#build

I do not have an understanding of the package management generation under ubuntu and no one with the appropriate knowlegde has stepped forward to define how to create ubuntu packages, as such I have not yet listed anything specific.

I followed your link to here
http://www.digitalsanctum.com/2009/03/1 ... buntu-804/
and installed the recommended packages.
I've now compiled and installed IM from source and at least it is able to render a gif but it still does not render the Thai script.
Nor does it have any idea of font path, I have to fully specify the path.

I think I'll file a bug report with Ubuntu.

to get IM to know where your fonts are so that you can just specify the name, you need to run Anthony's script imagick_type_gen at http://www.imagemagick.org/Usage/scripts/
