Just noticed that using the CGDataProviderRef with callback for data release
yields a memory leak:
CGDataProviderRef provider = CGDataProviderCreateWithData(NULL, buffer,
len, imageDataRelease);
CGColorSpaceRef space = CGColorSpaceCreateDeviceRGB();
cgImageRef = CGImageCreate(width, // width
height, // height
8, // bitsPerComponent
32, // bitsPerPixel
width*4, // bytesPerRow
space, // colorspace
kCGBitmapByteOrderDefault, // bitmapInfo
provider, // CGDataProvider
NULL, // decode array
NO, // shouldInterpolate
kCGRenderingIntentDefault); // intent
CGDataProviderRelease(provider);
CGColorSpaceRelease(space);
The imageDataRelease method is called after the image is released, with the
expected length of 240K (I expect this is called when the provider is freed).
However, Instruments shows a leaked Malloc of 236K with as responsible Caller
CGDataProviderCopyData, which makes no sense to me.
Any clues about what is copied here?
