@bo,

All images are not decoded properly using the latest trunk (r2949).
image 1.jp2 appears as fully black. The other are "blurred", on a black 
background which isn't right.

"Blurred" issue : Number of tile part specified is not right (same issue as 
issue 254 or issue 423).

cmap box doesn't appear in the jp2 header box & is not read at all by OpenJPEG.
cmap box is "invalid" (not according to standard but according to what it is 
intended to show) :
  Red channel shall use palette mapping using palette column 0 : OK 
  Green channel shall use direct mapping : KO, should be  palette mapping using palette column 1
  Blue channel shall use direct mapping : KO, should be  palette mapping using palette column 2

With all of the above manually corrected, images are properly decoded.

I will let someone else (Antonin ?) have a look at this because I might be 
missing something regarding ISO-15444 (which ever part/amendment/...).
Another thing is the values for precedence & approx in the colr box which 
aren't what's expected (but ignored by OpenJPEG)

This is the exact same issue as issue 235.
I'm not marking this one as duplicate just yet.

Here's a patch to get those images to decode properly (with patch from issue 
254 applied as well).

Not sure we wan't this in the trunk like this but it gives the idea of what's 
going on.
Solves the issue 235 as well.

Forgot to mention that it's been tested against the test suite with no 
regressions. Nevertheless, it shall be reviewed.

'xpdf version 3.03' does show all images clear and sharp.

Is the patch in trunk now? Please let me know when I can update the code, 
thanks!

@matthieu could you clarify this bug please (eg. the title). What remains to be 
done ? Only patch from comment #5 is needed ?

@mathieu,

Those files are not valid jp2 files for multiple reasons (3 issues, see comment 
#2), not sure how we could modify the title in this case.

The patch from comment #5 does not correct the issue 254 which comes with its 
own patch.
