Reverse transpareny

Probably something very simple but I'm stuck. I have a png file of an arrow. I want the arrow a color and the bg transparent. Currently the arrow in transparent and the bg is color. It seems this should be a simple fix.

In that png, the background is already transparent, but so is the inside of the arrow. Just do a fuzzy select of the inside of the arrow and fill it with a color, if you want to keep the outline, or fuzzy select the outside of the area, then invert the selection and fill with a color

I already have one image layer open..a blank highway sign. Added a couple text layers (street names) Now I want to add a couple of arrows. When I open arrow as layer it is much larger than what I am already working with Scaled it to proper size
If you posted yout Gimp file it would help, but is sounds like the arrow layer needs to be resized. Either layer->resize layer, or you could use the scale tool in the toolbox

don't want the arrow outline. grabbed fuzzy select tool, filled outside arrow. BG is color arrow is transparent. How do I invert the colors?

Edit Reason: typo

Your arrow looks terrible, scaling that original large image down so much is not a good idea.
My advice since it is such a simple shape, trace the arrow with the path tool Select Select -> All and clear the layer Delete Fill the path with a colour Edit -> Fill Path something like this https://i.imgur.com/gDPwW5f.mp4 You can use the same path in other parts of the image. All the transform tools (move / scale / rotate...) have a path mode.
I think you should not invert the colors, but the selection.
I mean, use the fuzzy select tool, select the outside of the arrow, then reverse the selection by going selection->invert THEN filling it with you foreground color, either by edit->fill with FG color, or even the bucket tool Something like that? But really, maybe Rich has a better approach. For something as simple as an arrow, maybe even drawing it with the pencil or paintbrush tool using straight lines with shift or shift+control for certain angles, and then just bucket filling it. By the way, I like the artwork there |
