Yes you are - RIP stands for "raster image processing", in other
words, any drawing.
The only thing I can find that may be related (based on [NSWindow
displayIfNeeded] being in the report) is that my app has a single
window
with a single view and I call:
NSImage* theImage = [[[NSImage alloc]
initWithContentsOfFile:mapImagePath] autorelease];
[window orderFront:self];
You could try doing this step first, before alloc/init the image. I'm
wondering if this is causing a drain of the autorelease pool.
[imageView setImage:theImage];
[imageView setNeedsDisplay:YES];
The file that this image comes from will be deleted later on, but once
initWithContentsOfFile is called, I assume it no longer needs the
file,
right?
I assume the autorelease is ok since theImage will be retained by
imageView.
Yes, unless it was autoreleased before that step was invoked, in which
case <theImage> will be stale which could be crashing the RIP internals.
Why not just -release the image after calling setImage, rather than
autoreleasing?
