BitmapData SetPixel()

[informatorius]

System.Drawing.Bitmap class has a SetPixel() method but it is slow for setting many pixels because each call locks in bitmap in the kernel. That is why Bitmap also has a LockBits() method which locks the bitmap and returns a System.Drawing.Imaging.BitmapData for direct manipulation.

The problem is this BitmapData class has no easy method for SetPixel() but you need to calculate with IntPtr and stride values.

I wish extension methods in System.Drawing.Imaging for BitmapData which allow fast SetPixel() for many pixels

@informatorius to propose new API please edit the top post to match the API review process guidelines

Note that System.Drawing is not necessarily a good choice for new development. We do not have plans to add features to it.

@informatorius have a look at https://github.com/LuizZak/FastBitmap
(edit: this is not .NET standard as of today 😢)
