openjpeg decompress issue

[gcode-importer]

Originally reported on Google Code with ID 326

I have a jp2 image,  it is fail to decompress to bmp when I run opj_decompress exe.


I found that p_colr_header_size == 35 not 7 in opj_jp2_read_colr function. 

If I ignore p_colr_header_size == 35, then jp2->enumcs get value 14, it is a CIELab
color space. Then I get a bmp, but the color is not the same to adobe acrobat. 

Can openjpeg support CIELab color space in the future?

Please help me, thanks a lot!!!

I have changed some code in openjpeg-2.x-trunk-r2833. With a reduction
factor of 2 I get the attached image.

Is this the image what you wanted?

change works?

thanks

There is no official code change until now. I have sent a patch, see Issue 324.
