Tips

When trying to dock a "dockable dialog", you have to grab the tab of the dialog, not the dialog window.

Questions

Answered:

• Q: How do you paint with transparency?
  • A: Use the "eraser" tool - between the paintbrush and airbrush tools.
• Q: How do you dock the dockable dialogs (aka toolboxes)?
  • A: Supposedly you can drop toolboxes onto a horizontal bar in the main toolbar, but this doesn't seem to work in some versions of Gimp (the bar may display a popup claiming you can do this, but it doesn't work). Alternatively, you can click on the left-pointing triangle-in-a-box on the right hand side of the main toolbar, which opens a menu that allows (among other things) adding any toolbox to the main toolbar as a tab.
• Q: How do you fix glowy red eyes in photographs?
  • A: Filters -> Enhance -> Red-eye removal
• Q: After expanding the canvas (e.g. when making two images adjacent), the new part of the image seems to be undisplayable – anything placed there becomes invisible. How do you make it visible?
  • A: Image → Flatten
    • There's probably some better way of doing this that doesn't remove the transparent layer, but I haven't figured it out yet. I'm still not entirely sure what's happening here; I just know that flattening the image does fix the problem. --Woozle (talk) 09:40, 23 March 2015 (EDT)
