Love2d Rotating an image

I would like to rotate an image in Love2D. I have found a documentation on love2d.org: https://love2d.org/wiki/love.graphics.rotate But I can't seem to get it to work when I try to load an image. Heres my code:

local angle = 0

function love.load()
    g1 = love.graphics.newImage("1.png") 
end

function love.draw()
    width = 100
    height = 100
    love.graphics.translate(width/2, height/2)
    love.graphics.rotate(angle)
    love.graphics.translate(-width/2, -height/2)
    love.graphics.draw(g1, width, height)
end

function love.update(dt)
    love.timer.sleep(10)
    angle = angle + dt * math.pi/2
    angle = angle % (2*math.pi)
end

Could anyone show me an simple example of rotating an image in love2d?

Solution

    You may be better off using the fourth argument, shown as 'r' to rotate images, such as:

    love.graphics.draw(image, x, y, math.pi/4)

    It's not worth the trouble of using the translate functions for a single draw, and keeping those for when you're batching many draws at once.
