Hi list,
i use this method the create a snapshot image from a QC published image output:
NSString *time = [[[self getSnapshotsDirectory]
stringByAppendingFormat:[[NSDate date]
descriptionWithCalendarFormat:@"%Y-%m-%d-%H:%M:%S" timeZone:nil locale:nil]]
stringByAppendingString:@".png"];
CGImageRef cgRef = (CGImageRef)[mainRenderer
valueForOutputKey:@"outForMasterImageWet" ofType:@"CGImage"];
NSBitmapImageRep *bitmap = [[NSBitmapImageRep alloc] initWithCGImage:cgRef];
[[bitmap representationUsingType:NSPNGFileType properties: nil]
writeToFile:time atomically:NO];
[bitmap release];
working fine, but the image always brighter then the original. I tested with
CIImage and NSImage too, but the same, wrong result.
Any idea what is wrong?
Thanks a lot,
.lov _______________________________________________
