What's that? Should I move this thread to the "Creating filters" forum?
Saying "Bug" is not a bug report. At least one should explain what they wanted to achieve, what they got instead and how to reproduce it. |

It's straight up cryptic but from what I gathered flip isn't behaving as expected.
Pixel X + 1 divided by image source = gradient on the X axis of the image (values between 0 and 1). When feeding this into the flip node it should flip the gradient along whatever axis chosen. In the example, it should be flipping on the x axis (and another on on the y). However that doesn't happen. So is this a bug or is this by design? |

Right, flip doesn't flip when used in pixel logic.

Because I first noticed this issue occurring with ONLY the Transform components, I posted five bugs. In addition to this one:
[Bug] Pixel Scale [Bug] Pixel Rotate [Bug] Pixel Offset [Bug] Pixel Lookup But, there are additional components that misbehave, such as the Elevation Gradient and Blur. Perhaps all the Processing components do. I am content with 7 bug points.  BugPixel_.ffxml _____________________________________________________

Just checked 5.007 and this is still a problem.

Already mentioned here. Although it is deceiving, it may be intended this way. Regular gradients are continuous, but Pixel X and Y are discrete. Or something like that. You can always use math to "transform" Pixel X and Y. For example: add=offset, invert=flip.

Thank you Indigo, the slight blur does it. But for flipping, for example, subtract nor invert don't work either, unless there is that slight blur attached.
So in my bug report defense, I say, Betis had [bug?] at the end of the title, whereas I declared [Bug] definitively at the start. Also, while his description was sufficient by GMM's standards, I provided the actual working examples of the problem. Merry Christmas to me.  _____________________________________________________

This is by design.
