realh, This book is old enough to be a carrier of facts. Facts in this book is simply old. There are many devices support 32bit RGBA pixel format. Only old or very-low-end devices can't support RGBA_8888 pixel format. Use this link<http://developer.android.com/reference/android/graphics/PixelFormat.html>to learn about PixelFormat class.
You may use a 32bit TGA or PNG format. But it will more better to use compressed texture formats. Compressed texture formats is a wide theme, you may learn about it here<http://developer.sonymobile.com/wp/2011/06/21/texture-compression-tips-for-sony-ericssons-xperia(tm)-phones/>, for example. It will be useful if you use OpenGL/ES. понедельник, 18 июня 2012 г., 17:44:24 UTC+7 пользователь realh написал: > > On Sat, 9 Jun 2012 02:13:34 -0700 (PDT) > EDan wrote: > > > I have a problem with images in android games.
