I honestly don't know if this is the right forum, but here goes.
I am running paint.net v3.5.5 and was wondering if there was any kind of plugin that could turn shaded color variants into transparency.
And here's what I mean:
With a gray color that is shaded lighter or darker, you can use the "Overlay" mode in the layers tab to merge said layer to a layer of color, and it will then have a shaded color.
And with that, by this suggestion/request for a plugin, I am saying this:
Make some kind of plugin that can merge a color layer and/or a grayscale layer to a fully transparent layer, and just make it be black with a certain number in the alpha value corresponding to the value you began with for the shaded color.
I am mostly sure that this has been proposed before, and this is why I'm also labeling it as a request. It is a most necessary thing for me to find out if this has been made ornot in the past, and whether or not a download for my version of paint.net (v3.5.5) is available.
I tried to make this seem as little like a word wall as possible, so it is easier to read, and fewer people will tl;dr. (too long; didn't read.)
Just wanted to know because I frequently use my phone and it would be really awesome to be able to make my YouTube thumbnails and other pictures directly from my phone. (One of my ideas, if it does get ported to mobile, is that there is a "Font Shop" for devices that aren't rooted/jail broken where you can get fonts of your own, or even just an option to import font files from the internet.)
