Hi,
I have a problem when scaling a black white image using
CIAffineTransform.
I want to scale up a image from e.g. 16x16 px to e.g. 160x16 px.
I thought the result should be the same as in Photoshop but is isnt.
The egdes are anti-aliased. So left and right of the image are
gradients to transparent. This is not what I want :-). Is there a way
to scale the image without Anti-Aliasing?
I loaded up a source image (http://www.thomasdingler.de/unscaled.jpg)
and the resulting screenshot (http://www.thomasdingler.de/scaled.png)
for explanation.
Thanks for every hint!
Thomas Dingler
