Question from the GIMP novice:
I received a jpg image which shall be used as a logo. Here's a part of it:

enter image description here

I'd like to have the background transparent, but the letters filled white. I was able to make the whole thing transparent spending some time with GIMP - to demonstrate it, I put it on a yellow background:

enter image description here

I can also fill the inside of the letters by

  1. selecting the outlines of the letters with the magic wand
  2. inverting selection
  3. de-selecting what I don't need (i.e. the rest of the image)
  4. fine adjusting the selection by manually adding/removing pixels and/or groups of pixels to make the whole thing smoother
  5. filling the selection with white color

I feel there should be an easier way, but my Google resarch didn't help. Can you? Are there more comfortable tools than GIMP for this?

Open the solid JPEG image in GIMP

  1. Use the Fuzzy Select tool (aka the Magic Wand) to select inside the letters, while holding down Shift as you click, to add each inside piece to the selection. You may need to adjust the Threshold in the Tool options to get a good selection. In my example below I set the Threshold to 79.

  2. In the layers panel create a new transparent layer. Select the new layer and click Edit > Fill with FG colour (assuming you already chose white as the FG colour).

  3. Select > None

  4. Click and drag the new filled white layer to the bottom of the layer stack in the Layers panel.

  5. Select the top layer. Click Colours > Colour to Alpha > OK. This will make it transparent.

As to the second part of your question. Yes there are better solutions for logo creation. The best option would be to use a vector image editor such as Inkscape (also free) to recreate the artwork from scratch. If the logo is simple enough and you know the font, this could be a quicker approach, plus vectors can be scaled without degradation in quality to any size you want.

  • Thank you so much! So my mistake was to turn white into transparent before selecting the letters' inside...

  • @mic - Possibly, that would add unnecessary complications I think.
