Hi everyone! Does anyone know how get pixel from [1,1] of the
CGImageRef?
I cant find it!!! (Just only via new context... )

CGImageRef LoadImageFromMainBundle(CFStringRef imageName)
{
CGImageRef image = NULL;
CFURLRef url = CFBundleCopyResourceURL(CFBundleGetMainBundle(),
imageName, NULL, NULL);
if (url != NULL)
{
CGDataProviderRef provider = CGDataProviderCreateWithURL(url);
image = CGImageCreateWithPNGDataProvider(provider, NULL, false,
kCGRenderingIntentDefault);
CGDataProviderRelease( provider );
CFRelease( url );
}
return image;
}

An image doesn't have pixels. Only when you render an image into a context do
you produce pixels, which is why you can only access pixels through a context.
