Remarks:

"Pels" is an abbreviated term for pixels. This function can be useful when you are converting a file that supports dots per inch to a DIB format, which supports pels per meter. The header structure of a DIB (the BIMAPINFOHEADER) contains two fields whose values are defined in "pels per meter": LONG biXPelsPerMeter and LONG biYPelsPerMeter.
