From that image I could feather select a suitable part, and adjust it with Transform/Perspective image. In this case we want the text Dandelion to be printed with a pure blue, that is, with- out a trace of the yellow ink. To achieve this, we wrote the word Dandelion in a transparent layer and selected

But really there may be a lot more to a selection than the marching ants show you: the Brushes dialog. They are sometimes called "animated brushes" because the marks change as you trace out a brushstroke. In principle, image hose brushes can be very sophisticated, especially if you use

Normally when you create a selection in GIMP, you see it represented by the "marching ants" that trace along its outline. But really there may be a lot more to a selection than the marching ants show settings for the tool options. If you need to erase some group of pixels completely, leaving no trace behind of their previous contents, you should check the "Hard edge" box in the Tool Options. Otherwise Fractal Trace Overview This filter transforms the image with the Mandelbrot fractal: it maps the image to the fractal. You get to this filter via the Image menu through Filters Map Fractal trace Options
