Basically what I want is to have the space around the question mark transparent, but have the edges keep their antialiasing.
Ok, so the way I've been making images transparent is by selecting Images/Mode/Indexed Color, which seems to flatten the image but retain the transparency of the question mark layer (unlike simply using the "Flatten" feature, which seems to get rid of the transparency of the layer and assume the color of "Background"). However, when I do this, Photoshop turns the pixels on the very edge of question mark (the antialiasing pixels, as it were; see red arrows) into solid black lines, making the edges very pixelated. What I'm wondering is how do I keep Photoshop from doing this?
Also, perhaps more importantly, is this the best way to do transparency? This method seems so roundabout and bizarre and I can't believe there isn't a more sensible way to doing transparency (but I haven't been able to find an easier way, even with tutorials).
Anyway, I'd really appreciate some help, I need this thing done by tonight. Thanks in advance.http://imagecorner.sorrowind.net/172/10.png
