love.graphics.draw

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

All objects have a local and global coordinate system. The object is positioned relative to the local coordinate system (LCS), and the LCS is positioned relative to the origin of the global coordinate system (GCS). The origin of the LCS 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.

One can offset the origin of the LCS to achieve a desired effect. For example, offsetting the origin to the object's center allows one to rotate an object about its center. Angles must be given in radians for rotation. With the origin at the center of the object, one can also use a negative scaling factor to flip about its centerline. Note that the offsets are applied before rotation, scaling, or shearing.

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

number sx (1)

Scale factor (x-axis).

number sy (sx)

Scale factor (y-axis).

number ox (0)

Origin offset (x-axis).

number oy (0)

Origin offset (y-axis).

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
