NAME

ScalerDiv -- Get the scaling result that BitMapScale would. (V36)

SYNOPSIS

    result = ScalerDiv(factor, numerator, denominator)
    D0                 D0      D1         D2

    UWORD ScalerDiv(UWORD, UWORD, UWORD);

FUNCTION

Calculate the expression (factor*numerator/denominator) such that the result is the same as the width of the destination result of BitMapScale when the factor here is the width of the source, and the numerator and denominator are the XDestFactor and XSrcFactor for BitMapScale.

INPUTS

factor - a number in the range 0..16383 numerator, denominator - numbers in the range 1..16383

RESULT this returns factor*numerator/denominator
