It’s a user man- ual, so it will not cover “nuts and bolts” topics such as how to write Gimp plug-ins; however, some basic scripting code on the enclosed CD. Warning! Look out for this symbol. Its purpose is to catch your attention, so you won’t miss passages of vital importance or essential warnings.

So you can copy-and-paste curves into the GIMP from Inkscape, and then drag a selection into Abiword to code required to support previews. David Odin has integrated this widget into all the current filters, so that now many more filters in the GIMP include a preview which updates in real time, and the various

So if you use a lot of those, the startup time will become pleasantly smaller, by order of a magnitude Moreover, GIMP is now capable of load- ing CMYK(A) PSD files (only 8-bit per channel for now). It does so by converting pixels to RGB(A) float using sRGB as the profile which, we know, is not good enough for

This creates a new, larger image with a white background. For the represents a part of the image which is selected.
