openjpeg decompress issue #326

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
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?

great, that's correct image.

I got the r2833 sources from svn, there are many changes, could you tell me 
which code change works?

thanks

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