Can a Gradient start at pixel 2?
Hi Gimp-user,
My goal is to understand tab-middle.png from Firefox chrome, and in
the process understand alpha transparency better.
The image is 1x75. I'm not sure of the correct way of saying this,
but from pixel 2 to 31 there is a decreasing amount of white visible,
(or an increasing value for the alpha channel). I think pixel 1 is gray.
Using the Gradient tool, I set Opacity to 70. I click the second pixel
in the image and hold the ctrl key while dragging. What I want to
happen is for the gradient to start at pixel 2 (where I clicked), but
it's starting at pixel 1. Is it possible to start a Gradient at
pixel 2 (or where ever I click), or do I just need to redo pixel 1
after the Gradient.
I've gone to the Channels Dialog and clicked off R, G, B, so I could
see the alpha channel. But some times it is so light that it is hard
to tell. Is there a better way to inspect the alpha channel?
Thank you.
