NAME

scale_image - Set the current scale-factor for the specified image.

SYNOPSIS

nil
scale_image( vid, sx, sy, time, interp )

DESCRIPTION

Alter the scale transform for vid . These values are relative to the initial dimensions for the object in question, while function such as resize_image internally converts the absolute values to relative scale. Interp can be set to one of the constants ( INTERP_LINEAR , INTERP_SINE , INTERP_EXPIN , INTERP_EXPOUT , INTERP_EXPINOUT , INTERP_SMOOTHSTEP ).

EXAMPLE

function scale_image0()


      a = fill_surface(128, 128, 0, 255, 0, 64, 64);


      scale_image(a, 2.0, 2.0, 100);


      show_image(a);
end
