first of all: many many thanks for the quick reply and for your incredible help. This is really awesome - and i learn alot.
btw: the videoclip is very impressive - and shows many important steps.
especially the step: "select the color (of the background)" and "erase it!" - this is pretty important!
thank you
What it shows:
Quote:Check the alpha-channel Layer -> Transparency - OK it has one
The trick: Scale the layer up 200% Image -> Scale image Use Interpolation = NoHalo
Color Select the background and Edit -> Cut to delete it
Select -> Invert and click on a dot to select.
Fill the selection with color (black)
Select -> None
The trick: Scale the image down to 50% back to original size, the interpolation (NoHalo) adds anti-aliasing.
on a sidenote: btw: plz plz plz. keep this video clip alive:

i have had situations wehere some guys on the net produced helperclips (videoclips) that were very helpful - but they vanished one or two days after publishing date - what a pidy.
dear Rich 2005 thank you for all your continued help!! You are a Gimp-Hero!!
i also will have a closer look at the c2a things
Quote: Use Color-to-Alpha (C2A) to remove a single color background when possible. It keeps semi-transparency including the edge anti-aliasing. For your image, some color is also removed. Fixed to a certain amount using C2A opacity slider but this can also removes anti-aliasing. Up to the user to decide what is acceptable.
thanks for all - keep up your superb work here..
Greetings
update: i am so glad to be here at the forum. Its awesome:
Rich2005 i am learing alot - and its a great community - experience to be here. I like the place for idea and knowledge-sharing. Its so great!
i want to go further with some GIMP-Experiments: especially with some that cover the Gradient-Color-Sheme.
some extra steps (and kind of "learing-and experimenting-stuff")
well i have a background that contains a color-gradient - i want to play around with the colors: see here https://imgur.com/a/UEJ6wpr
well i have the currently existing assemblage-image- consisting of a foreground 'the dots - and a background - the background that has got a gradient-color-sheme.
Well - what is wanted and what is aimed: i want to create a color gradient with the so galled "Sunrise Gradient" color scheme using the following hex codes (2D1D7A, 804565, AA585B)
i guess that i can work with those data - in the graphic-editor - my GIMP, which is surely the most appropiate tool here (or perhaps incscape or even Kria - but i guess that gimp is much much more apropiate here). Okay - i guess that the most image editing and design software provides such tools to define gradients using the so called color stops and their corresponding positions.
So i thought that i should be able to input these hex codes as the colors for a gradient stops, and then adjust the positions along the gradient to achieve the desired effect.
that said: i think that the color stops are important here: working with the Color Stops: (note - as mentioned above: this is only a example-color-sheme and subsequently all the color-stops are only examples)
Afaiik Gradients are defined by the above mentioned color stops, which are points along the gradient where a specific color is applied. While we can have multiple color stops to create a smooth transition between colors i think that at least two or three are sufficient to work well. What do you say here?!
Rich 2005, i think that i could work with the Gradient Editor: in fact: On a sidenote: i guess that GIMP is easier than Inkscape: I need to add the mentioned color stops, adjust their positions, and change the color associated with each stop.
Applying the Sunrise Colors:
In the gradient editor, we should be able to add one or two (or hmmm even three) example (!!!) color stops, one for each hex code.
Stop 1: Assign the color 2D1D7A.
Stop 2: Assign the color 804565.
Stop 3: Assign the color AA585B.
/(note: as mentioned above: these are example-color-shemes and color-stops)
the question is: can i then adjust the position of each stop (e.g., 0%, 50%, 100%) to control the color transition.
furthermore - and another question: can i add some kind of gradient type too: Am i able to choose from different gradient types, such as linear, radial, or angular. I guess that the so called linear gradients create a straight color transition ( while radial gradients radiate from a central point). At the moment i do not need any further adjustments:
I guess that GIMP is a bit easier to use - for this kind of project.
Look forward to any and all ideas
greetings
