Hi there, I've been experimenting with GIMP plug-ins. At present, I'm following the tutorial's example:- http://developer.gimp.org/writing-a-plug-in/3/myblur5.c My question is this; "How can I use GimpDrawable-functions on a preview window without modifying the original image?" To clarify:- In the example, blur() is passed a Drawable (from the main image itself), and uses it to make an "input" GimpPixelRgn (rgn_in). The raw pixel info from rgn_in is then processed and written as more raw pixels, to a different GimpPixelRgn, rgn_out. Rgn_out forms the basis of the preview: gimp_drawable_preview_draw_region (GIMP_DRAWABLE_PREVIEW (preview), &rgn_out) However, I want to annotate the PREVIEW (*without* modifying the original image's drawable) using gimp_pencil(). That requires a GimpDrawable, but rgn_out- i.e. the processed pixels which are used to create the preview's contents- is in GimpPixelRgn format. How do I draw on the output window? Getting the Drawable associated with the preview widget via gimp_drawable_preview_get_drawable() simply returns the main image's drawable, which we already have. Drawing to this (a) messes up the *original* image, and (b) has no effect on the preview (since that is taken from the processed rgn_out data). Any help would be appreciated, thank you. - triffid@xxxxxxxxxx _____________________________________________________________ Get your FREE OiNK-Mail ---> http://www.oink.co.uk Adopt an animal today and help support wildlife conservation ---> http://www.adoption.co.uk The Rainforests.
