Given that the code fragment shows it as a message being sent to “self”, this
looks like
I have this piece of code in my program:
CGImageSourceRef sourceRef = CGImageSourceCreateWithURL( (CFURLRef) url,
NULL );
if ( sourceRef == NULL )
{
... display error message 1
return;
}
CFDictionaryRef fileProps = CGImageSourceCopyPropertiesAtIndex(
I don’t recall if the URL can be a remote URL in addition to a file URL, but
regardless, check the status of the source ref with CGImageSourceStatus first.
The index value is used for compound images like animated GIFs and PNGs.

img_orientation];

I would think so, but it is hard to say without knowing what

Yes, the NSImage will
I haven't released my software (screensaver) in many years,
so please bear with me, I am not up-to-date any more how this works.
I have tried to create a new scheme, then changed the Build Configuration to
"Release".
