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 - (range: 0-1)
- (ULx,ULy,LLx,LLy,URx,URy,LRx,LRy);
- Number - (range: 0-1)
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 bottom left corner.
