NAME

switch_default_texfilter - Switch the default texture filtering mode for all newly created objects.

SYNOPSIS

nil
switch_default_texfilter( filtermode )

DESCRIPTION

This function accepts either FILTER_NONE , FILTER_LINEAR , FILTER_BILINEAR and FILTER_TRILINEAR which are texture post-processing stages usually supported in-hardware. Others will have to be implemented as temporary rendertargets with appropriate shaders.

NOTES

1: any value to filtermode outside the accepted values is a terminal state transition.

EXAMPLE

function switch_default_texfilter0()
      switch_default_texfilter(FILTER_NONE);
      a = load_image("test.png");
      show_image(a);
      scale_image(a, 1.25, 1.25);
      switch default_texfilter(FILTER_TRILINEAR);
      b = load_image("test.png");
      show_image(b);
      scale_image(b, 1.25, 1.25);
      local props = image_surface_properties(a);
      move_image(b, 0, props.height);
end
