Using python, I'm trying to find the color that is used on a layer. The layer has an alpha channel and it only uses 1 color on the layer. The problem is, I don't know where the colored pixels are. It may only be one pixel anywhere on the layer, or the entire layer may be filled.

The only way I know is the slow way:

* initialize a pixel_rgn * iterate across rows and down columns * look at each pixel. if its alpha is non-zero (ie. ord(pixval[3]) > 0)) then store the color and exit the loop.

I also need to find the color used on a text layer...

This (and the other text data) is stored in a parasite attached to the text layer. The parasite data is textual, and easy to understand.

A destructive way (i.e., work on a duplicate) of doing this would be to scale your layer down to 1x1 pixels and then fetch the color of that pixel (using the PDB function 'gimp-drawable-get-pixel')

Anyone have any ideas ?

Thanks a million...
