GNU Image Manipulation Program is an all-purpose graphic design application that works with all major operating systems: Windows, Macintosh and Linux. GIMP is capable of tackling almost any graphic design project, including the transformation of a photo into a line drawing or sketch --- a task it can accomplish in just a few clicks.

  1. 1

    Open GIMP. If it is not installed on your computer, use Synaptic Package Manager, YUM, or Yast --- whichever fits your Linux distribution --- to install the program. You can also find downloads at GIMP's website.

  2. 2

    Open the photo in GIMP.

  3. 3

    Select "Filters" > "Artistic" > "Photocopy."

  4. 4

    When the dialogue box opens, move the slider for "Percent White" up, toward 0.500. Watch the preview window to assess the look of the finished product.

  5. 5

    Click "OK" and wait for GIMP to process the change. After 10 to 20 seconds, you will see that your photo has been turned into a line drawing.

Tips and warnings

  • You can also use the Predator filter and then the "Color" > "Invert" tool to create a sketch.
