How can I resize an image without resizing the entire co-ordinate system

Code: Select all
window = love.window.setMode( 500, 500 )
love.graphics.setDefaultFilter("nearest", "nearest", 0)
monsterImage = love.graphics.newImage("Monster.png")
love.graphics.setBackgroundColor(255, 255, 255)
function love.draw()
love.graphics.scale(4,4)
love.graphics.draw(monsterImage, 50, 50)
end
When I run this, the image is 4 times larger but it's position is also 4 times bigger so this means it is in the centre of the screen. How can I only enlarge the image and not it's position.
Sorry for the, I'm guessing, easy question

Did you try scaling in the draw call instead of the entire stack? sx, sy are the parameters, check the API.

Image is drawn at its top left corner, but you can offset it to draw it at its center instead. You can use extended draw command with more arguments to do this.

I thought I did that in the draw call. Can you expand on what you think I should do. Sorry for the late response btw

See the
definition of the draw function. Scaling factors some in as inputs to the function.

I think shabbs15 confused the draw event/callback (love.draw) with the draw call (love.graphics.draw).
