I've just moved away from using sharp because it has problems with BMP images some of my users try to load, and I picked jimp. All good, except it's not very tolerant with images that aren't quite right.
One of my users tried to load a PNG file from "Snip & Sketch" on Windows, and jimp reported "Error: unrecognised content at end of stream".
I hit the file with pngcheck, and that went like this:
$ pngcheck ~/dodgy.png
/path/to/dodgy.png additional data after IEND chunk
ERROR: /path/to/dodgy.png
So jimp is reporting the right thing, but can I get it to ignore the rubbish after the IEND chunk?
