Re: Transparency
Hi, First thing to do is make sure you have an alpha channel: right-click, image, alpha, add alpha channel. If this option is greyed out, you already have an alpha channel. Second, you select the region you want to remove. You can use select, by color for this, or with the various selection tools (circle, square, hand-drawn, contigious regions, ...). Then press Ctrl-C to cut out the selected region, and the rest will be transparent. Your flattening problem/black bg in ie is probably related to not having an alpha channel. Flattening an image merges all layers, and removes the alpha channel (no more transparancy). Hope this helps.

RE: Transparency
Under linux, the color-to-alpha permit to make this. For PNG: with PNG, you can save alpha transparency but in the browsers, this functionnality isn't implemented in all cases. So... -Message d'origine- De: Gerhardus Geldenhuis [mailto:[EMAIL PROTECTED]] Date: jeudi 08 février 2001 10:59 À: [EMAIL PROTECTED] Objet: Transparency Hi I have a big logo which I have resized. Now I need to make the white transparent. Is there a easy way to do this. At the moment I copy the picture and paste it into a new bigger picture that is transparent then I use the eraser to erase pixel for pixel. My second problem is that when I save it to png and open it with IE5/NC the transparent displays black also when I flatten the image the transparency becomes black. How do I get a picture to display transparent in IE5 and what does flattening a image acctually do. Thanks Any help would be much appreciated. Cheers Gerhardus Geldenhuis
RE: Transparency Selection
That worked, but with one problem. I am trying to make an image with multiple depths which will require me to use the drop shadow multiple times. Or will it?

RE: Transparency Selection
Sorry about the noise. Right after I sent this message out, I found a way to do it, though not pretty. I kept selecting the regions I wanted the drop shadow to appear on, then inverted the selection. I finally got the look I wanted, but I also ended up with a bunch of transparent squares with drop shadows onto transparent backgrounds... Thanks! CK -Original Message- From: Kulish, Chris (Des Moines) [mailto:[EMAIL PROTECTED]] Sent: Friday, June 16, 2000 1:51 PM To: [EMAIL PROTECTED] Subject:Transparency Selection I realize this is probably a newbie question ... Is there any way to select the transparent section of an image? What I am trying to create is an image that will look decent on any color background (hence the transparency). I want the image to have a *cut out* appearance so I was going to select the transparent portion and use the drop shadow script. Or, is there a better way to do this? Thanks! CK
