    STRETCH FACTOR

    [ TDx_Draw_Library ]     [ next: Stretching and Shrinking ]     [ prev: Stencil ]

    Stretch factors are the values by which overlay surfaces must be multiplied to comply with hardware requirements. Stretch factor is reported multiplied by 1000 and only apply to the X axis, the Y axis may be stretched or shrunk to maintain aspect ratios without negative effects. Hardware without stretching or shrinking limitations of the destination rectangle will often report the minimum stretch factor as 0. For Example: Minimum and maximum stretch factors of 0.7 and 1.4 would be reported as 700 and 1400, meaning the destination rectangle can be a maximum of 0.7 times smaller or 1.4 times bigger than the source rectangle.
