Apr 19, 2016 at 11:04 comment added Paul The reason GIF images are jagged on their edges is due to an indexed colour scheme. The transparent colour is exactly that - a single palette entry, there is no alpha channel.
Feb 19, 2016 at 9:01 comment added Simon White File size is always an issue because bandwidth is always an issue, memory footprint on mobile devices is always an issue, computational overhead and its corresponding effect on battery life is always an issue. If you don’t know what you are doing and you for some reason don’t want to learn, then go basic: publish a basic 1:1 pixel ratio graphic at the actual size of the graphic.
Jan 20, 2016 at 7:23 comment added Cai @SOIA As long as file size isn't an issue theres no problem using oversized images and setting a smaller size in html.
Aug 4, 2015 at 0:33 comment added Scott That is not how @2x/3x images work. They are not resized via HTML tags.
Aug 3, 2015 at 23:58 comment added Anil Singh Scott, its the only way to export quality GIFs. Have you ever sliced a PSD for Apple devices @2x, @3x?. Bigger size is much better than bad user experience (in this case pixelated edges). If you have better way to do it, then answer the question, but don't degrade other's, if you don't know what you are talking about.
