again dear Rich2005
i am really happe to be part of this forum. Your ideas and your support are really great. Now i am trying to recap and to undersrtannd each single step you made. Here my first try to work on the "soluion" here.
see what i have understood in your example "
hmmm - i think that i can use th Color to Alpha filter in GIMP
this "color To alpha " can be found in the "Color"-Menu.
Well Rich2005 i have addes another example of and image here...
see the example:
what is aimed here: i want to mount this image to a certain background - a background with a gradient color sheme.
AFAIK :: this should converts a selected color in my image to transparency. This filter - note it is located under the "Colors" menu and well i think it might be useful for removing a specific color: In my case i want to remove the green.
color of the dots - i want to make them all black.
well i think this should be possible, (( while preserving anti-aliasing and blending effects.))
Here's my first step:
well i think i could do this with the help of an alpha channel. ... but how !?
note: at the end the dottted netwok should be "mounted on a "gradient background". - and then the all the network (dots and lines ) should get white ....
i guess that we can do this step with the so called "inversion".
.but at the moment not all steps are clear to me!
Sorry for all my noob-questions - i am trying to go ahead - but my steps are very verry small
