When the required amount of data was just a tiny bit larger than full a page size (one buffer increment), the decoder would stop since all compressed data had been read. However, the lzw decoder contains a small internal bit buffer for code decoding. That is, some remaining bytes had been retained and were still left to be decoded.

Formats
This table lists photometric interpretations and sample formats which are supported for encoding and decoding. The entries are ColorType variants for which sample bit depths are supported. Only samples where all bit depths are equal are currently supported. For example, RGB(8) means that the bit depth [8, 8, 8] is supported and will be interpreted as an 8 bit per channel RGB color type.
