How to manage large user images?

For mobile and tablets

If someone loads a jpg image 100MB+ or 4000x6000 and the canvas is significantly smaller will this be a problem? Could it cause a crash or slow the program?

Is there a way for a user to directly place an image into a sprite?

It depends on what you do with these images. If you allow to load many of them, then yes, this may cause problems.

One solution would be loading an image into a sprite, resize the sprite to the size of the drawing canvas, paste it on the canvas, then destroy the sprite and unload it from memory.

This way you'll end up with a small version of the image.

Some devices still have a hardware limit that means the maximum size image they can handle is 4096x4096. However many devices should now be able to handle up to 8192x8192. Beyond that it will likely only be supported on high-end discrete GPUs.

Thanks you! This helped:)
