I am getting closer, though. Enough that the action icons don't look too weird anymore.
Here are some of my notes. All images and adjustments are done with PNG files to support transparency. The sizes are rough, and can change a bit based on your source dimensions:
Scale the icon image size/canvas to roughly: 122 x 122 Final image offset (on the transparent background): 6 over x 6 down Final Size (roughly): 170 x 170
For the "Released" image:
1) "Select" the image
2) Create a drop Shadow Gray: Color: 21252a Offset X: 10 Offset Y: 10 Radius: 15 Opacity: 70 Allow resizing
3) Create a Drop Shadow Blue: (Repeat this step 3 or more times) Color: b2cbe7 Offset X: 0 Offset Y: 0 Blur Radius: 10 Opacity: 100 Allow resizing
4) Export as PNG (xxx_R.png)
For the Pressed image:
Scale the icon image size/canvas to roughly: 122 x 122 Final image offset (on the transparent background): 6 over x 6 down Final Size (roughly): 170 x 170
1) Select the image
2) Change the Layer Opacity to 15%
3) Create a drop Shadow Gray: Color: 21252a Offset X: 5 Offset Y: 5 Radius: 20 Opacity: 50 Allow resizing
4) Create a Drop Shadow Yellow: (Repeat this step 3 or more times) Color: ffae01 Offset X: 0 Offset Y: 0 Blur Radius: 10 Opacity: 100 Allow resizing
5) Export as PNG (xxx_P.png)
Let me know how this works for you ...
Now I have to figure out how to blend a blank channel button with channel logos in GIMP to get the 3D button look.
I'm a total amateur with image manipulation and GIMP. Just enough to be dangerous.
