CGImageCreate invalid image bits / pixel: 8

I am having issues creating a file that I can properly use as a ZXCGImageLuminanceSource, when I try use a png file directly as follows

ZXCGImageLuminanceSource *source = [[ZXCGImageLuminanceSource alloc] initWithCGImage:image.CGImage]

My app crashes and the error message is that this luminance source does not support cropping

So I thought I would create a CGImage using CGImageCreate as follows

CGImageRef newImageRef      = CGImageCreate (
                                                 width,
                                                 height,
                                                 bitsPerComponent,
                                                 bitsPerPixel, /
                                                 bytesPerRow,
                                                 colorspace,
                                                 bitmapInfo,
                                                 /
                                                 provider,
                                                 NULL,
                                                 false,
                                                 kCGRenderingIntentDefault
                                                 );

But this crashes with the following error message

Jun 13 04:33:33  nwtill[5517] <Error>: CGImageCreate: invalid image bits/pixel: 8.

I am unable to find a combination of parameters that works and that will create an image that ZXCGImageLuminanceSource can use and crop.
