Fails to parse valid png with 'unknown filtered scanline' #4

Open YenTheFirst opened 11 years ago

YenTheFirst commented 11 years ago

The attached image appears to be a valid png (browsers and image editors can open it), but PNG.js can't parse it, returning an error 'unknown filtered scanline'.

This appears to be a different parsing problem, so I'm opening it up as a second issue

unknown_filtered_scanline

Hi, there are about 15 PNG libraries on Github, which haven't been updated for years. That's why I wrote my own library UPNG.js - maybe you can use it instead. https://github.com/photopea/UPNG.js I just tested your image and it was parsed correctly (with UPNG.js).
