Is it possible to create Image objects on the fly and draw/blt on them? I could be missing something obvious here; I see there is love.image.newImageData, but it's unclear to me how you can draw or blit onto that image. Thanks.

Sort of.

Framebuffers would be best suited for what you're describing. Although framebuffers tend to break older hardware.

Alternatively if you really, really want to use images you can save the image data when you load it and then just paste what you want into a screen-sized image data and then turn it into an image and draw it. That is probably a bit slow though depending on your screen scaling and resolution.

There are two ways to draw to ImageData objects. You can play with individual pixels, in which case ImageData:setPixel, ImageData:mapPixel, and ImageData:getPixel are your friends. You can also paste other ImageData objects into an ImageData object using ImageData:paste.

This might be good enough for my current purposes. Thanks. It would be great if the "draw" functions in love.graphics were replicated for images as well...

Framebuffers exist for this very reason.
