how to get Bitsperpixel from a bitmap

Question

I have a 3rd party component which requires me to give it the bitsperpixel from a bitmap.

What\'s the best way to get \"bits per pixel\"?

My starting point is th

The Bitmap.PixelFormat property will tell you the type of pixel format that the bitmap has, and from that you can infer the number of bits per pixel. I'm not sure if there's a better way of getting this, but the naive way at least would be something like this:

var bitsPerPixel = new Dictionary() {
    { PixelFormat.Format1bppIndexed, 1 },
    { PixelFormat.Format4bppIndexed, 4 },
    { PixelFormat.Format8bppIndexed, 8 },
    { PixelFormat.Format16bppRgb565, 16 }
    /* etc. */
};

return bitsPerPixel[bitmap.PixelFormat];
