is there another a method for joining two images together so their opacity can be adjusted without one image showing through the other? That would solve the problem, too.īook cover transparency attemp^t Fullscreen_capture_712017_41303_AM.bmp.jpgįlattened view Fullscreen_capture_712017_43823_AM.bmp.jpg But if there's a simpler, more elegant way to get a clear background on a flattened image, I'll be immensely grateful to find it out. If I must go through all the _fun_ of redoing the layer mask, I'll suck it up and do it. But now I've got a gray, opaque background where I need it to be clear. Hooray, they're equally solid now and I can adjust their opacity simultaneously with no ghosting. I've experimented with opening a new view and flattening the girl and guy layers to make one image. The same thing happens when I use Merge Down. Problem is, when I reduce the opacity on the girl, the guy shows through her (see attached photo "Book cover transparency attempt"). I want to set a third image (a blueprint vector) behind them, then reduce the opacity on the first two layers so the blueprint lines show faintly through. The top portion of the book cover I'm generating features two separate images, a girl and a guy, brought together to give the illusion they're with each other in the same setting. My question: Is there a straightforward way to get a transparent background on a flattened image? The frame speed data and extra animation frames,Īre stored in extra chunks (as provided for by the original PNG specification).ĪPNG competes with Multiple-image Network Graphics (MNG),Ī comprehensive format for bitmapped animations created by the same team as PNG.ĪPNG's advantage is the smaller library size and compatibility with older PNG implementations.Hi, I've been making use of this forum the past few months as I learn GIMP, but this is my first time posting. So most standard PNG decoders are able to display the first frame of an APNG file. The first frame of an APNG file is stored as a normal PNG stream, It also retains backward compatibility with non-animated PNG files. While supporting 24-bit images and 8-bit transparency not available for GIFs. It allows for animated PNG files that work similarly to animated GIF files, Is an extension to the Portable Network Graphics (PNG) specification. The Animated Portable Network Graphics (APNG) file format. Through either a transparent color or an alpha channel. Raster file formats that support transparency include The animated gif image below has transparency. Some browsers still do not support APNG files yet.īut I disagree that animated gif images don't support transparency. For example using a GIF animation on a white background and placing it on a white web page would suffice. HOWEVER you can get away with a GIF transparent look by placing the animation on the same color in a web page. APNG is the way to go for animated images with transparent backgrounds. If it is going to be exported as an animated GIF deleting the white background in each layer will not work. (If I missed anything or got something wrong, someone please correct this as I have limited experience with APNG myself).Īpng 1.jpg Īpng 2.jpg Go to filters>annimation>playback and you will see your transparent background. When the dialog comes up make sure to uncheck the save background box and check the save as animation box. I cleaned up your gif a little and got rid of some of the white backgrounds in all of your images as best I could (in a hurry), recentered some and cropped them all. There are several threads here related to installing APNG so you can do this very thing. To save an animation with a transparent background, it has to be saved as an animated png or. By default, saving as a gif with a transparent background will act like saving as a jpeg and it will automatically put a white background behind it.
