Set the Buffer.
- Parameters:
-
buffer[] : a buffer of unsigned integers (4 bytes) *Rows*Stride in size Rows : Number of Rows Cols : Number of Columns Stride : The actual number of columns (useful for data alignment) Offset : The offset into a row ZigZag : A boolean, do we alternate count up/ count down per row? Wrap : A boolean, do we wrap if (Offset+Cols) > Stride? (handy for scrolling messages)
