Parameters

workBuffer
Pointer to optional work unmanaged memory buffer. Allocating the work buffer speeds processing if you call this method more than once, because if you do not allocate a work buffer, the method allocates and frees a temporary buffer each time it is called. The size of this buffer should be the same as the image's BytesPerLine property. Pass IntPtr.Zero for workBuffer if you do not want to use the work buffer

runBuffer
Pointer to input unmanaged memory buffer, which contains 1-bit compressed image data.

row
The number of the row to update. The first row is 0, and the last row is 1 less than the image height.

column
The column offset within the row to update. The first column offset is 0, and the last column offset is 1 less than the image width.

width
The number of pixels to retrieve.
