I need to view some of PVRTC-compressed textures from iPhone application (*.pvr) on OS X. Is there a viewer or format converter? ...
For iPhone game development, I switched from PNG format to PVRTC format for the sake of performance. But PVRTC compression is creating files that are much bigger than the PNG files.. So a PNG of 140 KB (1024x1024) gets bloated to 512 KB or more in the PVRTC format.. I read somewhere that a PNG file of 50KB got compressed to some 10KB and...
Hi, For iPhone game development, I switched from PNG format to PVRTC format for the sake of performance. But PVRTC compression is ruining the quality of the images.. I am using spritesheets with transparencies for the character animations.. and the pvrtc makes the edges look muddy around the character near the transparencies. I read th...
i want to display pvrtc images in my project which is build using opengl.I know about the tool to convert the png to pvrtc & also i have referd to the PVRTextureloader ex but no help,can u give me a simple ex of loading pvrtc image & displaying it also which files are req such as PVRTexture,Texture2D.how to use it. ...
(Quick version: jump to paragraph next to the last one - the one beginning with "But") I was happy in my ignorance believing that PVRTC images were 4 or 2 bits per channel. That sounded plausible. It would give 4+4+4+4 (16 bit) or 2+2+2+2 (8 bit) textures, that would have 2^16 (65536) and 2^8 (256) color depth respectively. But reading ...
I'm running into some issues with having a lot of UIImages in memory, so I was wondering if there is any way of using PVRTC images instead of PNGs in UIImages. ...
Edit:ok, sorry, I had a simple programming error, is there a way to delete this question? I have some compressed textures that are PVR files, but I cant seem to draw them in my iPad application using OpenGL ES. I can draw PNG files just fine, I know the PVR files are being loaded correctly. Are there some special OpenGL draw functions ...
I am using PVRTexTool to convert png files to pvr files but the tool seems to only be able to run on one file at a time(wont accept *.png as file name). does anyone know how to run it on a group of files at once? Its really a hassle to run it on all of my textures. ...
I have an iPad app that uses a ton(500+) of small(128x128, 256x256 or less) textures with alpha. At any given time there are probably 30~90 of these textures loaded with around 30 displayed. The app has slightly slow load times when I use PNG files so i am trying to improve them by using pvr textures. I want to keep as much quality as...
