Crop / NoCrop / Alignment question

[LGimmick]

Hi,

I have tried your program and I think the result is very good and it's realy fast.
But I noticed something concerning the crop-function:

The crop only works if the image content moves to the right - so the offset is oriented left. Otherwise the mirrored image content on the left side stays in the final image. [Global-Alignment and changed reference image does fix this, not sure about vertical movement].
And I have a few image-sets without any content-movement. The input-images have a resolution of 1600x1200 px. No matter what parameters I use, all aligned images (even the first one with reference = 0 and global-align) are created with 1664x1216 px and the result image contains the mirrored content on all edges, too.
I guess it's kind of the same effect and problem seems to happen somewhere in the calculation of the area with full data.

Hmm, I also received other report of similar problem.

Can you send me a test image set that reproduces the problem? If it is too large for upload here, you can mail me at petteri.aimonen (at) devembedded.com

I've sent you some images :).

@LGimmick Thanks for the logs. The key line was "Valid area not defined for aligned_Object3.bmp, using default.".

The OpenCL-accelerated code was not setting the valid area, so the bug only appeared when OpenCL was available. Fixed in commit 881e6b5.

There is new build for testing here:

New version works for me, too.

Thank you!
Works perfectly fine now.
