I think you misunderstand what I'm trying to do (or maybe I'm the one misunderstanding what you're trying to say ) To elaborate, I'm not tampering with the original layer in any way other than setting it to multiply. Doing this will let the layer below show through in the white areas, but not if the layer below is transparent. Sarkut reasoned this was because the Multiply layer blending mode disregards the alpha channel, thus blending white with white resulting in white. While this holds true for a completely transparent background with a colour value of #FFFFFF, it shouldn't work that way with a completely transparant #000000.

If I fill the background with #000000, Alpha: 0.0, I should expect to get a completely black result as the net is #000 * #000 and the spaces are #FFF * #000. The result is actually the same as the original: a black net with white, non transparent holes. It seems there is either an invisible white bottom layer that gets added at the very end of the process, or that #000000:0.0 somehow translates to #FFFFFF:1.0...

It performs beautifully, thank you (On the same note, would anyone kindly explain why Multiply didn't act as I had hoped?)

Hello everyone! My scenario is this: I have a high contrast black-and-white fishnet pattern, this one in fact, and want to remove the white background. As you can see there is some small white specks amidst the black threads which makes the magic wand produce less than desirable results. Now, what I tried was to simply add a new transparent layer beneath the B&W original and setting the original's blend mode to Multiply. In my mind, this would superimpose the black threads over the transparent blackground, alas I was proven wrong. The annoying thing is I can fill this new layer with red and have the threads come through beautifully with no aliasing and no white specks. Indeed, the process seems very simple if only there was some way of preserving the transparency through the process. Am I doing something wrong and is there a solution better than the not-so-magic wand? I've heard there is an [outdated] plugin that does approximately what I'm after but I'd rather keep to "vanilla Paint.net" if possible.
