<function name="PushFilterMag" parent="render" type="libraryfunc"> <description>Pushes a texture filter onto the magnification texture filter stack.⤶ ⤶ See also <page>render.PushFilterMin</page> and <page>render.PopFilterMag</page>. </description>⤶ <description>⤶ Pushes (Adds) a texture filter onto the magnification texture filter stack. This will modify how textures are stretched to sizes larger than their native resolution for upcoming rendering and drawing operations. ⤶ For a version of this same function that modifies filtering for texture sizes smaller than their native resolution, see <page text="render.PushFilterMin()">render.PushFilterMin</page>⤶ ⤶ Always be sure to call <page text="render.PopFilterMag()">render.PopFilterMag</page> afterwards to avoid texture filtering problems.⤶ ⤶ For more detailed information and a usage example, see <page text="the texture minification and magnification render reference.">render_min_mag_filters</page>⤶ ⤶ </description>⤶ <realm>Client and Menu</realm> <args> <arg name="texFilterType" type="number">The texture filter type, see <page>Enums/TEXFILTER</page></arg> <arg name="texFilterType" type="number">The texture filter to use.
