I think because the standard bitmap has the following properties.
• Bitmaps are saved row-based.
• When the height is positive, it is a bottom-up bitmap, that is, the last line comes first in memory.
• A row must be aligned on a 4-byte boundary.
• Color channel order is BGR (unless specified otherwise by BI_BITFIELDS masks).
