Are you sure that's right? This doesn't look like a conversion to dots per meter: size_t dots_per_meter = dpi * 2.54 * 100.0 To my eyes, unit-wise, that looks like dots/inch * cm/inch * cm/m = dots * m / inch**2. The original looks correct in regard to units to me: size_t dots_per_meter = dpi * 100 * (1 / 2.54) -> dots/inch * cm/m * inch/cm -> dots/m Am I missing something?
