flip images

[gimpygirl]

Hi

See image

- from this image I generate layers: each layer is a square of the image. So the layers have the symbols as you see them (wrong orientation).

- I need an existing plugin or plugin code to flip the layers so they are in correct orientation. How can I do this with existing plugin or plugin code or gimp operation?
(only for A -> Z and 0 -> 9)

Did you try to search flip in the Procedure browser?

... but if you use flip you have to flip twice (H&V), os better do a 180° rotation (search rotate-simple)

What is the correct to,go through all layers of image?

In the layers box next to the eye you can see a chain link. Shift + click in that row links the layers. From there you can go to Layer > Group > pack linked layers. This makes them all behave like a single layer. Then Layer > Transform > flip horizontally.

I work with multiple layers like this often. You can also resize them. When done just unpack and unlink.

Thanks but I was also looking for the correct code to loop through all layers of image. I'm making a plugin

Well, for an "apply to all layers", the attached snippet of code works for me. Equivalent is Layer -> Transform -> Flip Vertically for each layer.

You could of course just flip the whole image Image -> Transform -> Flip Vertically then no need to cycle through the layers.

Sorry I didn't realize you were making a plug-in. Good luck with it
