But this is interesting: with openjpeg-2.x-trunk-r2833 I get
colored images.
BMP is OK
PPM is OK
TIF is OK
TGA fails
PNG reports to have an alpha channel.
With has_alpha == 1 the white stripes are transparent in the foreground.
When I set has_alpha = 0 the transparency disappears.
So please try yourself.

But the resulting images (BMP, etc) are slightly blurred compared
with images from kdu_expand .

The attached file - from kdu_show on Win7- shows that the opj_decompress
image a4_2.png is nearly correct. Whereas the a4_1.bmp image of kdu_expand
on LINUX is wrong: the background is dark red-brown, the puppet is blue.
Why are the opj_decompress images blurred?

issue327-18_1805_a4_1.jp2 has an enumcs of 22: CMYK.
Adding OPJ_CLRSPC_CMYK in openjpeg.h and the function
color_cmyk_to_rgb() I got the attached image.

could you offer those addings?
will those addings be commited in openjpeg trunk?

CMYK (enumcs 24) can be found in part02_fcd15444-2annexm-JPX-2004.pdf.
Whereas openjpeg handles Part 1 with enumcs 16 .. 18.
So I suppose CMYK will never be part of openjpeg. Although several
issues exist with CMYK images:

I you want I can send you a patch for CMYK. It would contain the
files: openjpeg.h, jp2.c, color.h, color.c, opj_decompress.c .

CMYK could be part of openjpeg.
It already includes some Part-2 capabilities, like custom MCT.
Please provide the patch.

Here is the patch for CMYK files.
