An incredibly capable (and therefore very convoluted) image editor.

I use this:

• For converting .svg files to .jpg or .png
• (On Windows For editing .png files which have transparency, since mspaint.exe can't do that.
• For importing a page from a PDF, as an image.
• For transparent backgrounds

• For transparent masking

• GNU Image Manipulation Program

I don't think this came with Lubuntu, but if it didn't I got it from their repository.

• The first time it is launched it will complete its installation. Its first launch will be slow because of this. Don't worry, GIMP isn't as terribad as it used to be.

• Gimp's multiple windows IS FUCKING FUNDAMENTALLY WRONG. It's the main reason I've long-despised it.

  • Windows > Single-Window Mode
