PinTrader.club needed a way of allowing users to
- Upload massive images from their phones, without taking up too much resource
- Rotate images that sometimes were uploaded "wrong" (due to misreading of EXIF, or just weirdly taken pics)
We initially used Croppie.js to achieve this, but the results were often sub-par, with bits of the image getting cropped off, or white space being left around the image. PinTrader.club needs to be easy to use by everyone, we can't assume uploaders will take the time to learn our cropping tool.
This repo contains a series of experiments in playing with large images with a canvas element. All the examples live in the single file, index.html
