Re: Render In Image Bug



It's a horizontal line going from the centre of the
image to the right edge, and appears to be displaced
pixels from another part of the image. Changing the
various properties of the Render In Image patch
doesn't seem to help. Replacing the RII with a static
PNG solves the problem, but I need to render the image
with different dimensions, and input it to a Core
Image Filter.

Anyone come across this problem, and/or know of a fix?

We've seen similar sampling artifacts around the mid-point, horizontally (similar to what your shot demonstrates), even without any special CI filters or image blends. I think it may be a CI bug, but I haven't do enough testing to isolate it to be certain. If you've found that identically-sized images cause it to go away, you could try putting your inputs through a resizer first, to make them uniform. The resizer may still introduce the glitch, but it's worth a shot.


Are your images very large, by chance? (>4096 pixels per dimension) That's where we start seeing this kind of stuff (since CI resizes transparently when you feed it images that are too big for GL to handle)
