Issue using Gimp: black+transparent image transformed in [color] + transparent image
by dedec0 from LinuxQuestions.org on (#4YXEX)
I saved the 800x618 px PNG image https://openclipart.org/image/800px/...1540361873.png, displayed in https://openclipart.org/detail/30883...ledge-transfer .
It is an image with two basic kinds of points: transparent and black. But the limits also contain varying amounts of transparency, so the several curves that this image has look perfectly smooth. Good.
Now, i want to make this image to be (for example) purple and transparent, instead of black and transparent. I thought that using Gimp's menu "colors > hue-saturation" would be just what i needed, and that it would be simply scrolling the color choosing controls. But when i click on that menu, i receive this error:
"hue-saturation operates only on RGB color layers"
The same error happens when i use menu "tools > color tools > hue-saturation".
I tried to search for this error, but i could not a good result, in the few i got for this search. Do you know what i should do?
