Creating a Color object for each pixel while using Bitmap.LockBits faster than BitMap.GetPixel?

Question

Is creating a Color object for each pixel while using Bitmap.LockBits still faster than using Bitmap.GetPixel for each pixel?

Or maybe creating that Color is the main overhead of Bitmap.GetPixel as compared to the LockBits method?

Answer 1

Color is a struct, not an object. Overhead is negligible.

GetPixel() is so expensive because it has to lock and unlock the bitmap for each individual pixel. With LockBits() you can do it only once for the entire bitmap.
