Hi Laurent,
I am going to debug and let you know. Right now I have found these
lines.
Might they cause the trouble on Leopard && PPC?
number = CFNumberCreate(NULL, kCFNumberFloatType,
&destSize.width);
options = [NSDictionary dictionaryWithObjectsAndKeys:
(id) kCFBooleanTrue, (id) kCGImageSourceShouldCache,
(id) kCFBooleanTrue, (id)
kCGImageSourceCreateThumbnailFromImageIfAbsent,
(id) number, (id)
kCGImageSourceThumbnailMaxPixelSize,
NULL];
options = [NSDictionary dictionaryWithObjectsAndKeys:
(id) kCFBooleanTrue, (id) kCGImageSourceShouldCache,
(id) kCFBooleanTrue, (id)
kCGImageSourceShouldAllowFloat,
NULL];
I'm deeply suspicious of those typecast CFBoolRefs. Not every Core
Foundation class is toll-free bridged. CFNumber is, but I don't
see any
indication in the CF reference that CFBoolean is. Have you tried
using
NSNumber objects instead of those kCFBooleanTrue constants?
CFBoolean *is* toll free bridged to NSNumber.
OK, so where is that documented then? As I said, the CFBoolean
reference
says not a word about it:
<
http://developer.apple.com/documentation/CoreFoundation/Reference/CFBooleanRef/Reference/reference.html
By contrast, every other toll-free bridged CF class I can think of
explicitly documents that fact.
sherm--
I don't know but that what Apple do in the samples on ADC (http://developer.apple.com/samplecode/ImageApp/listing4.html).If
this is the cause of the crash, i think this sample should be change.
NSDictionary* options = [NSDictionary dictionaryWithObjectsAndKeys:
(id)kCFBooleanTrue, (id)kCGImageSourceShouldCache,
(id)kCFBooleanTrue,
(id)kCGImageSourceShouldAllowFloat,
nil];
