UIImage size method before save it

[carlosl3g]

Hi, is it posible to do that?:

NSLog(@"SIZE OF IMAGE: %d ", sizeof(UIImageJPEGRepresentation((imageView.image), 0.5)));

because I got 4 as answer so I think it's a pointer.

How could I get an image size if I don't have the path yet?
I've seen:

- (NSDictionary *)attributesOfItemAtPath:(NSString *)patherror:(NSError **)error

but I need the size before the image is saved.


Thaks for your help.

There is a property that returns the size like:

805300712

but this is a CGSize wich is actually widht and heigh and I want to get the size in bytes.

It's OK I've found it:

NSData *imageData = [[NSData alloc] initWithData:UIImageJPEGRepresentation((imageView.image), 0.5)];
	int imageSize = imageData.length;
	NSLog(@"SIZE OF IMAGE: %i ", imageSize);
	if( imageSize > 0)
