CoreGraphics takes so poor fps, can anyone can tell me a faster one?

[liangsai]

I use CoreGraphics to flip my virtual 2d canvas to screen, but fps < 10.

If don't blit anything to the canvas, just flip a blank canvas to screen, fps < 20.

My code like the below, anyone can tell me a way to get faster fps? Thank you very much!


- (CGImageRef)createImagevoid*)adata widthint)width heightint)height{
CGDataProviderRef provider = CGDataProviderCreateWithData(NULL, adata, 320*480*4, NULL);
CGColorSpaceRef colorSpaceRef = CGColorSpaceCreateDeviceRGB();
CGImageRef ir = CGImageCreate(
width,
height,
8,
32,
4 * width,
colorSpaceRef,
kCGImageAlphaNoneSkipLast,
provider,
NULL,
NO,
kCGRenderingIntentDefault
);
CGColorSpaceRelease(colorSpaceRef);
CGDataProviderRelease(provider);
return ir;
}

- (void)drawRectCGRect)rect {

CGContextRef context = UIGraphicsGetCurrentContext();

//CGContextTranslateCTM(context, 0, 480);
//CGContextScaleCTM(context, 1, -1);

CGContextDrawImage(context, CGRectMake(0, 0, 320, 480), imageRef);

}

@liangsai - You can check out cocos2d for iphone to get better FPS performance for 2d game type applications.

Thanks, but My memory render buffer is ready code. I just, just want to blit the memory buffer to screen, with high fps.

Thanks a lot. Any new solution can help me?
