Here's the end result: Thanks, Jeff

I couldn't get it to behave. I've settled for hosting the sign on a rounded-corner black square that itself has a gradient transparent drop shadow. There's more than one way to skin a cat. Thanks, Jeff

I like that, it's definitely easier to use. It still leaves jagged edges, though. I need to fade in the alpha, from 0 to 255 accordingly. Right now I'm working on some VB.NET code for this; the results it's producing are the closest I've gotten yet. I was hoping there'd be something available 'out of the box,' but it's looking like I have to roll my own. I'll post the code back here if I get it to behave. Thanks, Jeff

For the life of me, I can't get past square one with Tanel's Color-to-Alpha plugin. I'm trying to get this foreground image: to look halfway decent on both of these backgrounds: To complicate matters further, there'll be more backgrounds to come, too, certain to be lighter in color (homage paid to Murphy's Law). I think it's me. The concepts of hue, saturation and brightness escape me. I've tried combinations of settings all over the map, but nothing gets even close. The jagged edge just won't go away. Any ideas? Thanks, Jeff

Ah, that makes perfect sense. The obvious solution, then, is to just slow down the release rate

I gave it a run, still got the white halo. Maybe my settings are off. I fired off a quick note to the plugin's author, with a link to this thread. With any luck he'll spot it and check in.

I think it will. I'll give it a try tomorrow and report back here. Promise

Gosh, I hope not. I'll keep digging.

Say, that looks like it might be the ticket. I can't be dangerous, 'cause I don't even know a little bit

Hmm... Is there a way to automate something like this: - Pixels with white color get full transparency - Pixels with white/green mix get the corresponding mix of transparent/green - Pixels with green color get no transparency

Yes, exactly. The tree needs to look like it was drawn originally on the striped blue background. I'm pretty sure Paint.NET can do this, and that it's just one of those 'easy if you know how' things.

OK, sounds good. Did that. Got the attached image, no tree, strange transparency. What did I miss?

I'm not sure, but I think you were able just now to say a lot with only a few words. I wish I could do that I'd like to try what you're suggesting, but I have no idea where to begin. Could you elaborate a bit? Thanks!

I'm absolutely new to Paint.NET, and not even that handy with graphics editors in general. I'll try to digest your reply as best I can, but I may need to ask for a bit more how-to breakdown. Thanks in advance for your patience... I've been searching the forum and experimenting with the program for just about a couple of hours now, but I'm not finding a thread that exactly addresses my problem. Many come close, but not exact. I don't know the program (nor its concepts) well enough yet to adapt these replies to what I'm looking for, so I find I have to ask. I'm building a website for which we have an artist sketching some drawings for us on white paper. They'll come to me as .jpg scans. My task for the banner image is to replace the white background with full transparency, with the transparency gradating to color at the same rate as the white gradates to color. I get bonus points that I'm willing to share if I can do all this without getting the trademark white halo that so often appears when replacing background colors. I'm attaching the site's banner background image 'Banner.jpg' as well as a second image 'Tree.jpg' that I plan to test with. The tree image seems a good one, as it has plenty of the above-described white/color gradient. If with your assistance I can create a .png with all of the above details we will have won the battle. In my searching I came up with links to a couple of plugins: http://paintdotnet.forumer.com/viewtopic.php?f=16&t=4394 http://paintdotnet.forumer.com/viewtopic.php?f=16&t=31446 Do either of these apply? If any, which would work best to accomplish all this? Naturally any discussion on how to use either of these is lost on me at the moment. Thanks, Jeff Bowman

Hello, just signed on. I probably won't be too terribly active here, as I'm more of a programmer (VB.NET) than I am a graphics aficianado. I do find a bit of an artistic streak in myself, though, however novice it may be. And, as I'm an absolute beginner at Paint.NET, well... with your gracious assistance I may be able to overcome that. First of all I'd like to extend a warm thank you and appreciation for all the hard work of our forum moderators. Folks, I have trouble keeping up with my own limited volume of a few emails a day—I have absolutely no idea how you manage to do this. I'm in awe I must admit I'm a bit curious about Rule #11. Please correct me if I'm mistaken, but it would seem quite valuable to be able to post a reply to any thread, even one that's "expired," especially when the reply is a solution to the stated problem. This way someone searching the forum at a later date can more easily find what he's looking for in a single thread, rather than wade through several trying to find a solution. Also, the original thread is more likely to more accurately describe the original problem. May I ask the history behind Rule #11? What sort of thing was happening to inspire its creation? You've got my curiousity piqued Thanks, Jeff Bowman
