How to add a solid background to an image thats transparent - jford11609 - 06-14-2018

I have an image of a clock and the background of the clock is transparent. Im wanting to add a solid background to it without making the whole canvas that solid color (around the clock). Its a pretty intricate clock with lots of little spaces so it would take me forever to fill it with the bucket. I know there has to be an easier way to do this. Please help! I posted a link to something similar im working with.

Do a fuzzy-select on the background: click in one corner of the backrground then shift-click in the other corners (and inside the chain ring) to add them to selection.
Select>Grow by two pixels, then Select>Invert
Add a new layer, filled with transparency
Bucket fill the selection on that layer with the required color. This shoul dgive you the silhouette of the watch
Move that layer below the watch layer (drag it down in the Layer list, or Layer>Stack>Lower layer

Btw, not very hard to have a different color for the dial:

Are you really using WinXP ?

Ofnuts method is the most efficient but another way using the selection tools. All good practice.

This is using Gimp 2.10 but Gimp 2.8 much the same. You might get Gimp 2.8 installed in XP Wink

Thanks so much! This worked out perfect for me!
