Re: Can image be loaded without loading profiles?

I should clarify that I am using the term "Profiles" as it is used within a certain portion of the ImageMagick code rather than in the more narrow sense of published standard profiles like ICC, EXIF. Specifically, I am concerned with TIFF images and the TIFFGetProfiles() method of tiff.c w...

Access Violation when TIFF tag value cannot be allocated

When TIFF tags are being read and the memory allocation for a tag's data fails, the tag's pointer is correctly set to 0 and the error is noted at that time. However, later in TIFFGetProfiles(), when such a tag is encountered, the 0 pointer is dereferenced, causing an access violation. Adding &&a...
