64 bpp, 16 bpc, kCGImageAlphaLast (what image data tells us) is not supported
64 bpp, 16 bpc, kCGImageAlphaPremultipliedFirst (that I mention in a PR) is not supported either

As far as I can tell we should simply draw all images using the same pixel format which is best for rendering (for instance, 32 bbp, 8 bpc, kCGImageAlphaPremultipliedLast). End users should be able to easily alter this behaviour by implementing custom image decompressors.

// See Quartz 2D Programming Guide for more info
guard let contextRef = CGBitmapContextCreate(nil,
    Int(imageSize.width),
    Int(imageSize.height),
    8,
    0,
    CGColorSpaceCreateDeviceRGB(),
    CGImageAlphaInfo.PremultipliedLast.rawValue) else {
        return image
}

Hi,

How did you set the environment variable CGBITMAP_CONTEXT_LOG_ERRORS and what did you set it to ?

-Thanks
