Unknown values for 'colr' box should result in unknown colorspace, not an error during parsing #247

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
In the JPX format, an 'Meth' value of 1 in the 'colr' box can have additional 
data. For a strictly JP2 format this is not possible. The 2.0.0 code considers 
it an error when the 'colr' box has additional data. I think this should be 
fixed so that it ignores additional data (and results in an unknown colorspace).

This can be fixed by changing openjp2/jp2.c, line 1088 from:

if (p_colr_header_size != 7) {

to:

if (p_colr_header_size < 7) {
