[Bf-committers] Accessing UV/Image Editor Image Data

[Brecht Van Lommel]

Hi,

I'd look at the text editor implementation of copy/paste and make it
work similar. That is, make copy/paste operators in the image editor,
have those call a new WM_clipboard_image_get/set function (like
existing WM_clipboard_text_get/set), which will then call GHOST.

Probably you'd pass the pixels and width/height. For how to access the
pixels in an image, you could look at the IMAGE_OT_invert operator in
the image editor.

Brecht.

Getting frustrated with having to save the result, open it in Pixelmator, making adjustments and repeating, I figured I'd code in a quick "copy to clipboard" operator.
