I skimmed the last 3 pages and didn't see this requested yet:

Load from clipboard...

I thought about doing something like that before, but just never got around to it. I see what I can do later today.

Hi APShredder,

Often I want to compare two layers A and B, yielding a third layer C which contains the signed differences between the respective pixels of A and B. The Difference blend mode in Paint.NET only gives the absolute difference, so I lose information about whether the pixel from the top layer was brighter than the pixel from the bottom, or the other way around.

Difference blend mode: C(x,y,channel) = |A(x,y,channel) - B(x,y,channel)|
Signed difference: C(x,y,channel) = [A(x,y,channel) - B(x,y,channel)] / 2 + 127.5

Technically this can be done with built-in blend modes, Invert Colors, and Levels. But it's a ten-step process

Could you potentially add this to BlendModes Plus? I'd be grateful! I can upload an example of the intended effect later, if you need one.

This is really fun to play with, and even more fun to legitimately alter pictures with.

I'll have to make an obligatory "Will it Blend?" parody video.

@Neil Cassidy - I don't see why not! I'll try working on it later tonight, but could you do me a favor, and upload an example of what it should look like. Thanks!

@Rail Tracer - Thanks! And if you do make that video, send me the link. That's something I'd like to see.

Thanks for agreeing to help! My current procedure gives the wrong result for color images (unless it's run individually on each channel). It takes almost 40 operations to get the correct result in Paint.NET. It should only be a few lines of C#.

Wow...WTF. I haven't noticed this until now. But it's awesome! Great job! You can be the blend modes master. LOL

Got em!
This will be AMAZING - Blend modes are my near favorite part of PDN. Thanks! ^^

UPDATE: Copy from clipboard feature added, Signed Difference blend mode added.

Several problems (v3.5 Stable on Windows 7 64bit):

--
Clicking the text copy image to clipboard doesn't select the radiobutton (seems illogical given that radiobuttons can have text).

--
Repro: Load an image and switch to clipboard mode.

Code:

Repro: Copy something to the clipboard, click copy image to clipboard, wait for it to render, copy another image, switch to file mode and back.

Bug: If the clipboard does not contain an image, there is a valid file path in the textbox, and the user selects the clipboard option, the plugin will crash.

If the image from the clipboard or file is a different size than the layer, it will be stretched to fit the whole layer. This, I think, should be optional and also respect selections. That is, if the stretching is enabled, it should stretch to the selection rather than the whole layer.

Also, an option to position the fake layer would be nice.

Thanks for the error reports guys. I'll probably have them fixed by tomorrow afternoon.

EDIT: Nevermind. They should be fixed now. And I'll try working on the resizing and placement things later.

"Signed Difference" works great, APShredder. Thanks very much!

APShredder · **Posted:** Sun Nov 08, 2009 11:12 pm

No problem. :wink:

You just keep adding more and more blend modes, don't you? :wink:

Love them all!

Got any other ideas for amazing plugins?
