Severe gif encoding bug

[mjphaynes]

There is a bug here:

gif-endec/src/Encoder.php

Line 183 in 9b9b7d4

$byte |= (ord($this->firstFrameBytes[10]) & 0x07);

See here for correct logic: https://github.com/lunakid/AnimGif/blob/master/src/GifCreator/AnimGif.php#L361

This causes gifs to be corrupted in certain situations

I have an issue with corrupted gifs as well, but the linked code looks comparable. I think the issue is elsewhere, but I've not found it yet

[mjphaynes]

Yeah this could be your issue as well as this is a pretty major flaw in the logic.

I don't know if this package is still maintained? If it is I could submit a pull request?
