Hi,
I have a very annoying crash/hang on snow leopard 10A432 when
converting CIImage to NSImage.
Here is the stack :

Is anyone familiar with this issue?
Best Regards.

The method I use to convert a CIImage to an NSImage :
@implementation CIImage (IMImagesUtilities)
- (NSImage *)nsImageWithSize:(NSSize)size {
if (([self extent].size.width == 0) || ([self extent].size.height ==
0))
{
return nil;
}
CIImage * imageToAdd;
//NSCIImageRep * ciImageRep;
NSImage * resultingImage;
NSRect newRect;
if (CGRectIsInfinite([self extent]))
{
newRect = NSMakeRect(0, 0, size.width, size.height);
imageToAdd = [IMImagesUtilities cropImage:self
withRect:newRect];
}
else
{
newRect = [IMImagesUtilities NSRectWithCGRect:[self extent]];
newRect = NSMakeRect(0, 0, newRect.size.width,
newRect.size.height);
imageToAdd = self;
}
// Create a new NSBitmapImageRep.
NSBitmapImageRep * theBitMapToBeSaved = [[NSBitmapImageRep alloc]
initWithBitmapDataPlanes:NULL
pixelsWide:newRect.size.width
pixelsHigh:newRect.size.height
bitsPerSample:8
samplesPerPixel:4
hasAlpha:YES
isPlanar:NO
colorSpaceName:NSDeviceRGBColorSpace
bytesPerRow:0
bitsPerPixel:0];
// Create an NSGraphicsContext that draws into the NSBitmapImageRep.
(This capability is new in Tiger.)
NSGraphicsContext *nsContext = [NSGraphicsContext
graphicsContextWithBitmapImageRep:theBitMapToBeSaved];
// Save the previous graphics context and state, and make our bitmap
context current.
[NSGraphicsContext saveGraphicsState];
[NSGraphicsContext setCurrentContext: nsContext];
// Get a CIContext from the NSGraphicsContext, and use it to draw
the CIImage into the NSBitmapImageRep.
[[nsContext CIContext] drawImage:imageToAdd
atPoint:CGPointZero
fromRect:[imageToAdd
extent]];
// Restore the previous graphics context and state.
[NSGraphicsContext restoreGraphicsState];
resultingImage = [[NSImage alloc] initWithSize:newRect.size];
[resultingImage addRepresentation:theBitMapToBeSaved];
[theBitMapToBeSaved release];
return [resultingImage autorelease];
}
@end
Best Regards.
