How can i remove the text from background of this image using gimp?

The text is composed by different colors so i cannot use "color exchange" option for every single color of the text.

Any idea?

  • Why are you asking how to remove the "PREVIEW" watermark? I assume whoever added it doesn't want you to use the image. Is the image copyright? If so, sorry but I won't help. – Billy Kerr Feb 26 '18 at 11:13
  • It may be that recreating the background is much faster than removing the text. – Takkat Feb 26 '18 at 13:02

  • @FlyBob - then why don't you just type it out again? – Billy Kerr Mar 6 '18 at 18:05

Deceptively simple. The orange color of the text is 100% red, 78% green, and 0% blue, and the rest of the image is black or white. So making a monochrome image from the red channel alone is enough. For this use Color>Components>Channel mixer, set to "Monochrome", and use Red=100%, Green=Blue=0%.

  • Then accept the answer :) – xenoid Feb 26 '18 at 23:43
