Before I report them as problems, I thought I'd check with other users. First, I can't seem to get the Perspective Clone to perform the way it does in the video tutorial. The cloning operation doesn't appear to lean in the direction I've adjusted the perspective handles. I'm wondering if I'm misunderstanding the use of the handles or something. Anyone else having problems using it?

Second, I've noticed that the Healing tool clones garbage pixels after a while. It starts out working okay. After a short time, the first click to clone is fine, but if I hold down the shift key and then click again to perform a straight line clone operation the pixels cloned along this line are (for lack of a better term) garbage. Is anyone else seeing this? I've noticed that the problem is not consistant - it doesn't always show up.

FYI - I'm using 2.4.4.

I've posted examples of each on my web site:

Clone problem: http://www.graphics-muse.org/source/perspective.png In this example, I expect the perspective to be toward the left and back but that's not what happens when I paint the cloned area. Healing tool problem: http://www.graphics-muse.org/source/healing.png The problem is visible on the right side where three straight line operations have started adding colored pixels to the otherwise black and white image. Note that while it may appear the source location is too far right and the operation may have gone off the right edge of the image, it hasn't as the image extends to the right beyond the visible canvas border. So it's not a boundary edge problem.

Also using 2.4.4 on Linux, I have been unable to replicate your problems. The perspective worked intuitively and the heal seemed to work no matter what I did

I've assumed that, like the video tutorial, if I pull the upper left and right handles down toward the center of the canvas that I'm setting the far end of the perspective view. So a square cloned with the perspective clone tool would have it's left and right sides aligned with the left and right sides of the perspective box. This is my impression of what should happen based on the video tutorial. Is this how it's supposed to work? If so, it's not doing that, as the sample picture shows. In fact, it almost looks like the application of the perspective is opposite of what I'd expect. And the size of the clone object is not always what I expect. Sometimes it gets larger. Sometimes (as in my example) it gets smaller. What deteremines the cloned object's size?

From the example I've created I can't deteremine what the expected

results should be given the movement of the handles to specific locations.

Hi,

Howdy.

No, that's not how it's supposed to work and that is also not what the video tutorial is showing. Perspective Clone allows you to clone objects in the perspective plane. You are supposed to adjust the plane to match the perspective of your image. Then you can clone objects in that plane and their size will be adjusted accordingly.

I guess I'm not understanding what the perspective plane is, then (or at least how to adjust the handles to work within it). I'll play with this some more tonight and see if I can catch on. If not, I'll post some more specific questions.

Thanks.
