The image itself does not contain size, position, shearing and such.

You provide this information when drawing with love.graphics.draw.

Take a look at that documentation page and reply if there's still a question :)

No you can't resize image. You can scale the image during drawing as mentioned above, but the size of the image itself can not be changed.

@erasio, the image returned from love.graphics.newImage actually does contain, at least, the size (dimensions) of the image.

Ah, but what if you display a scaled image and dump the result to a file, then reload it? ;)

Then scale it back up to the original resolution for the pixelly goodness (or badness if you use filtering).
Do you recognise when the world won't stop for you? Or when the days don't care what you've got to do? When the weight's too tough to lift up, what do you? Don't let them choose for you, that's on you.

That is not resizing in image. That is creating new Image.
Btw. Python PIL is cheating also it does:

Code: Select all

img = img.resize((new_width, new_height), Image.ANTIALIAS)
And that is creating new image. And face it most libs can't resize image.
All they do is creating new image and than transfering old data.
