paint.kim Posted January 30, 2007 Share Posted January 30, 2007 hey, i was wondering if it is possible to set the layer transparency based on the color value. for example, i'd like a layer to be transparent wherever the layer is white (value>=255), or maybe i'd like this layer to be transparent where the underlying layer is dark-grey or darker (value<=30). there is something similar for layers in photoshop. if it's not possible at this point, i think this feature would be useful. thanks for a great program!

barkbark00 Posted January 30, 2007 Share Posted January 30, 2007 Alpha Mask Import Plugin I think this is what you are looking for. Let me know if it is not. I know that I use to do exactly what you are saying. Quote Take responsibility for your own intelligence. 😉 -Rick Brewster Link to comment Share on other sites More sharing options...
paint.kim Posted January 31, 2007 Author Share Posted January 31, 2007 hi! thanks for the reply. this plugin is very useful for masking, and will come in handy, but what i had in mind originally was a little simpler. E.g., "here is a picture with a person in front of a white wall. i want the wall to be transparent, therefore i will say Blend If Layer Is >= 230 (out of 255)." just something i've found useful in the past for simple stuff, but i'm sure i'll manage without. :wink: Quote Link to comment Share on other sites More sharing options...

The selection is now transparent. Quote My DeviantArt | My Pictorium | My Plugins | Donate via Paypal Link to comment Share on other sites More sharing options...

I'm sure one of these programmer guys could write something like that. Other that that, I think MadJik's solution would kinda work for you.

I'm sure one of these programmer guys could write something like that. Other that that, I think MadJik's solution would kinda work for you. Right... of course, in the example I gave, the magic wand works perfectly fine. So let me change my example from a person to a tree in front of a white wall. Where little bits of white are showing through. Then the magic wand is... less magic and more tedious, and just choosing white to be transparent would be much simpler. Anyway, I appreciate the suggestions, but I'm not really looking for workarounds. I'll just file this one under "Feature Request". Thanks again for the replies!

barkbark00 Posted January 31, 2007 Share Posted January 31, 2007 What program did you use to do this before? Can you post a screenshot of that dialog? Quote Take responsibility for your own intelligence. 😉 -Rick Brewster Link to comment Share on other sites More sharing options...

paint.kim Posted February 2, 2007 Author Share Posted February 2, 2007 What program did you use to do this before? Can you post a screenshot of that dialog? Here is a screenshot of the layer blending options in action, from Adobe Photoshop CS (ugh). Click on to see full screenshot. In this case, I edited the "Blending Options" of the top layer, the trees, and chose to "Blend If" the gray value was greater than 80. As you know, photoshop is both (a) ridiculously expensive to legally own outside of work, ( heavy and takes 5 billion years to load, © does way more than i need, and (d) has the worst history/undo/redo system EVAR! so i don't even use it at work. i love paint.net, this is just one little feature i miss. Hopefully this illustrates what I had in mind! Quote Link to comment Share on other sites More sharing options...
Oneshot Posted February 2, 2007 Share Posted February 2, 2007 Thats funny, I just asked the same question here > http://paintdotnet.12.forumer.com/viewtopic.php?t=3346 Its called Croma-key BlotBait posted a few answers I'm going to try. I didn't try them yet because I'll need a RED or BLUE background in my case. BUT to be able to remove 1 color from a picture would be the same thing.
