Only Interned Explorer does not support the format yet.Īpple added animated stickers to iMessage with the release of iOS 10. Binary transparency without any workarounds! Is it safe to use animated PNG?Įxcellent question! Chrome, Firefox, Safari and now Microsoft Edge all support APNG. With TinyPNG the background becomes transparent again. Still need to support Internet Explorer 6? It normally ignores PNG transparency and displays a solid background color. Is it supported everywhere?Įxcellent question! The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices. I have excellent eyesight but can’t spot the difference either! Use the optimized image to save bandwidth and loading time and your website visitors will thank you. In the above image the file size is reduced by more than 70%.
The result better PNG files with 100% support for transparency. All unnecessary metadata is stripped too. By reducing the number of colors, 24-bit PNG files can be converted to much smaller 8-bit indexed color images.
With throwaway programs like these, you can do lots and lots of stuff.File size 57 KB vs Shrunk transparent PNGĮxcellent question! When you upload a PNG (Portable Network Graphics) file, similar colors in your image are combined. If you want to do it to the nearest power of two, you can change the way you determine the width and height, and so on. If you want to do it for all the images in a directory, you may want to look into System.IO.Directory.EnumerateFiles(). New Rectangle(0, 0, originalImage.Width, originalImage.Height), Using (Graphics g = Graphics.FromImage(convertedImage)) Var convertedImage = new Bitmap(64, 64, PixelFormat.Format32bppArgb) Var originalImage = (Bitmap)(Image.FromFile("original.png")) I just want to illustrate how simple it is to write a simple image manipulation program): using System It may sound really difficult, but it's not if you use a language and a library that lets you do stuff like that.įor example, in C# using System.Drawing, you can make a program that resizes an image to 64圆4 (I know this is not exactly what you need. What I usually do when I need some very specific image manipulation (but also text, sound and pretty much anything), is to make a trivial throwaway program that does it for me.
I have tried ImageMagick before, but right now i already started building my own gimp plugin thanks to the examples provided below, have done 1 gimp plugin before but this will be a new challenge. (Nothing we do not know about, basically power of two stuff.) A relevant document about image optimization on Corona can be found here. I am using Corona SDK, and using OSX Mavericks. I know they should be the ones doing the resizing but at this point, but i would like to quickly correct the error for the sake of the whole team. My main problem is that the art department guys sometimes save hundreds of textures with the wrong resolution, for example, 1025x1025, which occupy 4 times as much memory as a 1024x1024 image, or or 560x520, which could be scaled down to not use too much memory. is there any Gimp plugin example, or a simple and fast to use tool that already does this? For example, i have multiple images with similar properties like width = 66 and height = 62, i would need the resulting image to be 64圆0, keeping its ratio.
