Apple Bug Friday! 59
This bug is The NSImageInterlaced, it does nothing!. It was filed on 2007-05-12 at 00:29 PDT.
Summary:
The NSImageInterlaced property never appears in input images, whether or not they are of an interlaceable type, and if they are, whether or not they are interlaced.
Steps to Reproduce:
- Use +[NSBitmapImageRep imageRepWithData:] to slurp a PNG or GIF file, interlaced or not.
- Send the image rep the valueForProperty: message, asking for its NSImageInterlaced property.
Expected Results:
You get an NSNumber of either YES or NO.
Actual Results:
You get nil.
Regression:
Unknown.
Notes:
The documentation of NSImageInterlaced says that it is only used on output. I think that it makes sense to also be disclosed in input.
