love.graphics.draw

love.graphics.draw

Draws a Drawable object (an Image, Canvas, SpriteBatch, ParticleSystem, Mesh, or Video) on the screen with optional rotation, scaling and shearing.

Objects are drawn relative to their local coordinate system. The origin is by default located at the top left corner of Image and Canvas. All scaling, shearing, and rotation arguments transform the object relative to that point. Also, the position of the origin can be specified on the screen coordinate system.

It's possible to rotate an object about its center by offsetting the origin to the center. Angles must be given in radians for rotation. One can also use a negative scaling factor to flip about its centerline.

Note that the offsets are applied before rotation, scaling, or shearing; scaling and shearing are applied before rotation.

The right and bottom edges of the object are shifted at an angle defined by the shearing factors.

Examples

Draw an image (the Hamster Ball) at 100 by 100 pixels

function love.load()
   hamster = love.graphics.newImage("hamster.png")
end
function love.draw()
   love.graphics.draw(hamster, 100, 100)
end

Draw an image (the Hamster Ball) from the center at 100 by 100 pixels, rotated by 90 degrees

function love.load()
   hamster = love.graphics.newImage("hamster.png")
   width = hamster:getWidth()
   height = hamster:getHeight()
end
function love.draw()
   love.graphics.draw(hamster, 100, 100, math.rad(90), 1, 1, width / 2, height / 2)
end

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

Draw the top half of an image (the Hamster Ball) at 100 by 100 pixels.

function love.load()
   image = love.graphics.newImage("hamster.png")
   quad = love.graphics.newQuad(0, 0, 128, 64, image:getWidth(), image:getHeight())
end
 
function love.draw()
	love.graphics.draw(image, quad, 100, 100)
end
