SetTexCoord -Documentation by tcxxs-

Limit the region of a texture drawn by the Texture widget.

obj:SetTexCoord(left,right,top,bottom);
obj:SetTexCoord(ULx,ULy,LLx,LLy,URx,URy,LRx,LRy);

Parameters

Arguments

(left,right,top,bottom)

Number - 0 -- 1   - actually, not bounded, but 0-1 is the texture's actual area

(ULx,ULy,LLx,LLy,URx,URy,LRx,LRy);

Number - 0 -- 1   - actually, not bounded, but 0-1 is the texture's actual area

Note

The function cut a sub-region,use the new TopLeftPoint is (left,top),new BottomRight is (right,bottom),so you can use the function to rotate the texture or sub-region. The more complex 8-argument form allows for arbitrary affine transformations, see SetTexCoord Transformations for details.

Example

getglobal("MyAddOnTexture" .. id):SetTexCoord(0, 0.5, 0.5, 1);

Details

Use this function to select a sub-region of a texture for display in a Texture widget. Note that the coordinates are normalised, and that the origin is the top left corner. (Note: Tested in patch 2.0.6, and the origin is in fact in the top left, and not the bottom left as was previously stated)
