Available since LÖVE 0.9.0
This function is not supported in earlier versions.

Resets the current coordinate transformation.

This function is always used to reverse any previous calls to love.graphics.rotate, love.graphics.scale, love.graphics.shear or love.graphics.translate. It restores the current transformation to its default state.

This function is called automatically right before love.draw.

Function

Synopsis

love.graphics.origin()

Arguments

None

Returns

Nothing.

Example

local image = love.graphics.newImage("path_to_your_image")
function love.draw()
	love.graphics.push()   -- stores the coordinate system
		love.graphics.scale(0.5, 0.5)   -- reduce everything by 50% in both X and Y coordinates
		love.graphics.draw(image, 0, 0)  -- you can see a scaled image that you loaded on the left top of the screen.
		love.graphics.print("Scaled text", 50, 50)   -- print half-sized text at 25x25
		love.graphics.draw(image, 0, 0)  
			love.graphics.push()
			love.graphics.origin()  -- Reset the state to the defaults.
			love.graphics.draw(image, 0, 0) -- Draw the image on screen as if nothing was scaled.
		love.graphics.pop()   -- return to our scaled coordinate state.
		love.graphics.print("Scaled text", 100, 100)   -- print half-sized text at 50x50
	love.graphics.pop()   -- return to the previous stored coordinated
	love.graphics.print("Normal text", 50, 50)
end
