Interface
- If you run the GIMP under KDE, start it in a new desktop: that's currently the only way I found to get all the GIMP windows to reappear when working with multiple applications.
- All tools have simple key shortcuts that are very useful, try to remember them.
Saving
- PNG format allows you to choose the compression level. The default maximal compression level acts strangely (artifacts on the image), so if that happens reduce the compression level to 5-6.
Selection
- When making a selection, for example with the rectangle tool, you have to confirm it by clicking on it. Until this click, the selection is easily modifiable by using the sub-rectangles appearing
- A selection also usually shows the layer boundaries (which is a good thing).
- You can create a new selection based on a layer "contents" (parts that are not transparent). This is done by right-clicking on the layer and choosing "Alpha to selection".
- If you create a anti-aliased selection, this will apply to future operations. For example, a fill on an anti aliased rectangle will not fill uniformly the rectangle with the color; the edges will get a smooth transition.
