Report-an-Apple-Bug Friday! 58
Slightly late because I had to devise a way to determine whether a GIF file is interlaced. (I settled on GifBuilder, in case you’re curious.) This ties in with the next two bugs; I’ll blog both at once next week.
This bug is NSImageInterlaced documented as working on half of known interlaceable types. It was filed on 2007-05-12 at 00:27 PDT.
Summary:
The NSImageInterlaced property is documented as only working on PNG files, despite GIF also supporting interlacing.
Steps to Reproduce:
Expected Results:
It describes NSImageInterlaced as applying to both PNG and GIF.
Actual Results:
It describes NSImageInterlaced as only applying to PNG.
Regression:
None known.
Notes:
It is possible to do interlacing in TIFF. The downsides are greater file size and the possibility that some readers may not understand the file.
