I have 1 RGB layer; the background. Its background is white. There is a solid line on this image. I wish to fade its left end out to white. How can I do this please?
If you are drawing the line, use the gradient tool, and make your right end the color and the left end white.
If you are editing someone else's work, try this:
- Use the Selection tool and draw a marquee around the part you want to fade.
- Go into Quick Mask. It should be on Mask is Selected Area.
- Select the Gradient tool.
- Draw gradients until you like how it fades. That is, until you like how the gradient of the Quick Mask color covers your line.
- Exit Quick Mask.
- Layer → Layer Mask → Hide Selection.
If you don't like how it looks, back up in your History to the Quick Mask step and repeat as needed.
Quickly, young hero:
- Create a new layer
- Draw a line
- Select the area around it (the "background")
- Invert Selection
- Select your gradient tool
- Make the primary color the color you want, and the secondary color entirely transparent (Alpha?)
- Delete the contents of your selection (delete key?), and draw the gradient from one corner to the other corner of the line
- Merge layer into your main layer (or leave it alone, if you want)
May your sword stay sharp!
