Hi,
I'm trying to use the parseAPNG() function in node.js but keep receiving the 'Not a PNG' error.
I'm reading the .apng file to a 'Buffer', then converting it to an 'ArrayBuffer' before sending to parseAPNG().
Am I doing something wrong?
Thanks !

It should work that way. Try to check your data, the raw (A)PNG should start from '\x89PNG\x0d\x0a\x1a\x0a' byte sequence.

Yes the raw file is ok...
I'm converting between the 'Buffer' and 'ArrayBuffer' using the function suggested here:

Do you know if that is correct?..
Thanks :)

Could you show your APNG and the exact conversion code?
