Re: [Gimp-user] Drop shadow
I have an idea for you, but I have no idea whether or not you want to spend this kind of time greating an animated GIF. GiMP can of course do it, but you would almost be better off drawing the cells by hand and usinging your smart phone and a GIF-making app to get the final result. If you care creating a drop shadow, you are using layers to get there, right? Even the filter uses layers. But in GiMP, to make an animation, each cell has to be a layer -- so you must effectively flatten the layers every time you make a new cell. My thought is this: you need to have 3 images open: 1. Your master image in which you are creating each cell (using layers) 2. a "slave" image in which you flatten the master and then convert from RGB to indexed 3. your animation file, in which you paste each new cell as a layer as you convert it If that workflow doesn't make sense to you, I can give you more steps to follow. The idea is that you are doing the high-res, high-quality work in the master image; you are taking the master image each time you change it and flattening it down and reducing the colors for use in a GIF; and you are assembling the GIF in its own indexed-color file. Hope that helps! On Tue, Jun 12, 2018 at 12:37 PM ustharp wrote: > I am creating a GIF animation over a static background. I want the > background > to have a drop shadow.

Unfortunately the GIF format does not support partial transparency (no alpha channel). If you know the exact background the GIF will be displayed on, you can use that background as an opaque layer - with a soft-edged drop shadow added where you want it. :o) I would suggest trying an animated PNG file, which supports partial transparency (alpha channel present) but alas, if your animation will be displayed on a web page, Inernet Explorer and MS Edge do not support that format (according to Wikipedia - may be old info). I never made an animated PNG file, so any advice on that including whether the GIMP can make them, or whether you would have to make the frames in the GIMP and assemble them with another program. :o/ ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
[Gimp-user] Drop shadow
I am creating a GIF animation over a static background. I want the background to have a drop shadow. For some reason when I do this, my drop shadow turns solid... it does not fade out. It is just a solid offset layer. I can't for the life of me understand why.

For that to work the image is in RGB mode. Indexed color mode as used by gif only has transparency either on or off. Going from RGB to Indexed results in losing the drop shadow semi-transparent pixels. see screenshot 1 First thing to do in RGB mode is merge the background and drop shadow layers. Still in RGB mode you then have a choice. Either, lose the transparency of that bottom layer as screenshot 2 Layer -> Transparency -> Remove alpha channel Then export as an animated gif. see screenshot 2 Or, before exporting as an animated gif, convert to Indexed Mode. Image -> Mode -> Indexed and Enable dithering of Transparency. That gives the impression of shading. see: screenshot 3 rich: www.gimp-forum.net Attachments: * http://www.gimpusers.com/system/attachments/931/original/01-drop.jpg * http://www.gimpusers.com/system/attachments/932/original/02-drop.jpg * http://www.gimpusers.com/system/attachments/933/original/03-drop.jpg -- rich404 (via www.gimpusers.com/forums) ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
Re: [Gimp-user] drop shadow
Steve, that's wonderful -- hand roll my own shadows! Seems so simple and obvious after it's explained that I wonder why I ever thought I needed a plug-in for this. So cool!

Select one of the layers with a photo in your Layers dock, right click the layer thumbnail and do Alpha to selection 3. Select the new transparent layer, drag and drop to the main canvas to fill the selection with black. 4. Select the other layer with a photo, right click and do Alpha to selection again. 5. Select the new transparent layer, drag and drop to fill the 2nd selection with black. 6. Do Select None (or control + alt + a) to clear the selection. Your transparent layer now has two black rectangles, hidden under the photos in the layers above. Use the tool at Filters Blur Gaussian Blur to soften the edges of the shadow rectangles, then turn on the Move tool in your main toolbox and use the arrow keys on your keyboard to tweak the location of the shadows. Adjust the shadow layer's transparency if required. :o) Steve ___ gimp-user-list mailing list gimp-user-list@gnome.org https://mail.gnome.org/mailman/listinfo/gimp-user-list -- Helen Etters using Linux, suse12.3 ___ gimp-user-list mailing list gimp-user-list@gnome.org https://mail.gnome.org/mailman/listinfo/gimp-user-list

I used to know how to do this! Help? Suse 12.3, gimp 2.8 Thanks much I'm curious how this is even happening in the first place, because from my experience the drop shadow uses, in order: 1 - If you have a selection, it creates a shadow based on the selection mask. 2 - Or, if your layer has an alpha channel, it uses that. 3 - Otherwise, it uses the entire current layer. It's true that performing your own shadows is completely doable, but if it's something you do a lot then having an automated script/plug-in for it does save you a lot of work. (Assuming it functions correctly, of course.) Do you have screenshots of what your results are? If it's creating a drop shadow around the entire image border then the most obvious problem would normally be not having the correct layer selected before executing it (or having layer boundaries extended to the whole image). -- Stratadrake strata_ran...@hotmail.com Numbers may not lie, but neither do they tell the whole truth. ___ gimp-user-list mailing list gimp-user-list@gnome.org https://mail.gnome.org/mailman/listinfo/gimp-user-list
