Hello all..
In my Core Data app, Im fetching a NSData property corresponding an image.
Now Im binding an NSImageWell value to the Entity's array controller and
setting the propper keypath and setting the value transformer to
IZImageTransformer
The image value for each MO appears but I realized that its opacity its less
than 1.0, I mean its not 100% opaque.
this is what Im doing in the IZImageTransformer
+(Class)transformedValueClass{
return [NSImage class];
}
+ (BOOL)allowsReverseTransformation
{
return NO;
}
-(id)transformedValue:(id)value{
if(value == nil)return nil;
NSImage * image;
if ([value isKindOfClass:[NSData class]]) {
image = [[NSImage alloc] initWithData:(NSData *)value];
}
else {
[NSException raise: NSInternalInconsistencyException
format: @"Value (%@) is not a NSData.",
[value class]];
}
return [image autorelease];
}
any idea why Im not getting full opacity?
Thx
Gustavo
