Create PVR texture from png file

Hi,

I have one image file in png format. I want to create texture out of that image. To convert into texture format .pvr I am using following command:

$ ./texturetool -e PVRTC -o ./image.pvr ./image.png

image.pvr file is getting created but with zero bytes file size. I loaded and tested it nothing comes blank screen.

Please tell me syntax of conversion from png or jpg to .pvr.

I am using this code to load created texture:

NSString *path = [[NSBundle mainBundle] pathForResource:@"image" ofType:@"pvr"];
NSData *data = [NSData dataWithContentsOfFile:path];
textures[kTextureone] = [[Texture2D alloc] initWithData:[data bytes] pixelFormat:kTexture2DPixelFormat RGBAPVRTC4 pixelsWide:512 pixelsHigh:512 contentSize:CGSizeMake(512,512)];

Not getting texture.

I guess that you are missing the format

I use (to convert from png to pvr) the following:

./texturetool -e PVRTC -p aPreview.png -o output.pvr -f PVR input.png

Hope it helps,
