Re: [Gimp-user] pucker skin
On 2008-01-29 [EMAIL PROTECTED] Wrote Quoting Zhang Weiwu [EMAIL PROTECTED]: I wish to achieve the effect to add a deep pucker on the skin, as of the bone is broken underneath the sking or there is a joint underneath. Or should I use the word wrinkle or crinkle, I am not sure. I am a new gimp user who just managed to learn conceptual things like layers, path, selection, mask and channel, and now I don't know where to start to read if I wish to get it done. You might try using the Grow and Shrink options of the IWarp filter (Filters-Distorts-IWarp...). Thanks. Actually I tried these things first, this is the first plugin I managed to use, it can hardly achieve the effect having pucker on the skin. I knew it's difficult to express what I wish to have, thus here is attached a picture of sking with no pucker and a picture sking with a pucker. Have a look at the screen you can also correct my expression (actually, I am not sure at all of pucker is the right word). attachment: nopucker.jpgattachment: pucker.jpg___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Have a look at the screen you can also correct my expression (actually, I am not sure at all of pucker is the right word). At first glance it looks like a simple issue, just to use some plug-ins. Look deeper into it it's isn't simple.. Seems to me there are two options there: 1. Copy half of the sking, paste into a new layer with trasnparency, use IWrap on both layers (the move method), move both layers towards the 'pucker', make smart use of alpha channel and drop-shadow effect. This is too difficult to create something that really looks like 'pucker'. 2. Use the displacement map filter, as I was suggested through a private email from the list. The problem is lack of good methodology to create approciate X/Y Displacement Coefficient layer. Whatever I create, it just doesn't look like. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] generate png images with transparent pixel that filled with correct color on viewers do not support transparency
The email subject says it all, though it's very long. I am used to creating png images with transparent pixels/area that I can safely (safe = even work with the worst browser that people call IE) use on the web, the trick is to convert image with transparency to indexed color with less then 256 colors, save the png image. Now another challenge: I use very bright background color on the web for most png-pixel-transparent images, these images look very bad if they are put on dark background. And for one situation I am in now I have to make these images display fine on viewers that do not support transparency, e.g. xview. My png image (with transparent pixels) display on xview with very dark background color, close to black. First I thought it's because white color is not in the color index, and I open gimp to add white color in the index map (verified by adding a single white pixel stored and displayed), and save as png image (when saving, gimp's background color setting is also set to white), and I get a new png image that display very dark red color on xview. I think perhaps it's possible to set what transparent pixel color value in GIMP? How should I set this value?
