Color Reproduction Issue about jsgif HOT 2 OPEN

Maybe my pull request might be worth a try.
#34

By default the sampling factor is 10 which means not all pixels serve as input for the neural net in NeuQuant.js. This way pixel colours can be lost. Setting it to 1 will ensure that the network is learning from every pixel

from jsgif.

You can try gifenc

Because my react-native-gifencoder is also some fork of gif.js

But in my react-native-runescape-text I replace react-native-gifencoder with gifenc for Fix when one color e.g. '#ff0000' only have 1 or 2 or 3 pixel in one frame, the generated gif pixel will be '#9f0000'; fix some frame not transparent but black; reduce gif size 10x

from jsgif.
