GIMP 2.8.10/Win. 7 Prof., 64 Bit: Transparency, preserve color, use non-used color
A first hello,

I'm familiar with the basics of transparency. Let us assume I have a picture of an technical device ("object") with an white background. Now I want to set white as transparent color. But usually any object contains the backgroud color - here white.
How do you handle such a case? What is the most convenient way to slightly modify such a color in the object? Is there a way to find a non-used color in the picture which could then be used as background? Any other suggestions?


Many thanks and greetings
ypmig

Hi and welcome.
Firstly I suggest you have a read of the techniques described here.
Without seeing the image, I guess you could try the Fuzzyselect tool adjusting the tool options (threshold, Select by: etc) if the background is just a single color. Once you have the background selected use Edit->Clear to remove.
Hope this helps in some way.
