How to fill areas of a rotated image...?

Hello everyone,

I'm a very novice user so feel free to explain in detail....! And I apologize for my ignorance of the proper terminology in posing my question.

I'm trying to rotate an image. Actually, I figured out how to rotate it. But I can't figure out how to fill in the "empty" triangular areas that represent the area between the edges of the original image and the horizontal and vertical edges of the canvas. I would like to fill these spaces so it is not obvious that the image was rotated. How can I do this?

What is the standard way to manipulate images in this manner?

I've attached a sample image that I rotated.

Thanks in advance.

Pull out the crop tool ;)

There is no routine way to "fill in the blank spaces." You would have to pick an acceptable fill color and live with the little triangles, or crop the image to a rectangle containing only real picture elements.

Or you could apply your painting/drawing skill to fill in the triangles.

Your picture is reasonably rotated - however, the edges have been cropped to the "canvas" - the rectangle containing the original image. In order to keep all the detail in the picture, you would have had to "Fit Canvas to Layers" - a selection under the "Image" tab.

Have fun, and keep exploring.

I would crop the image, see:

When I rotate, I crop to the shortest corners. Unless you are rotating a large degree, you loose very little image. Your image was only rotated a couple of degrees and looses very little.

gud luk,

OK, thank you. I need to understand the "Fit Canvas to Layers" feature better. I read the documentation here http://docs.gimp.org/sv/gimp-image-resize-to-layers.html

So I guess I need to do this: 1. Create a new layer
2. Rotate the image
3. Execute the "Fit Canvas to Layers"

I have to play with it to understand what I'm doing....!
