Jagged lines when using distortion correction

Unread postby dfmalan » 22.02.2009 12:41


I noticed that the output image sometimes displays "jaggies" after using a distortion correction filter. This seemed to be a problem only with earlier versions, but I now also spotted this in 4.92.

I include an image after processing with
* Barrel Distortion Correction -10
* Horizontal perspective +7
* Rotate + 9

I suspect that it's especially the perspective correction that's to blame. I indicated some of the jagged transitions with green arrows.

Are you aware of this problem? An interpolation issue maybe?

Thanks for reporting this. This bug appeas only if you apply geometrical corrections and rotation.
