Andreas Molzer 4d8c64bf1e Fix lzw decoding stopping short of full decode 
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.

Andreas Molzer ed22865f04 Remove unused and incorrect Wrapping impl 
This is used in the predictor and should be reversible but for floating
point the simply addition is not. It should instead be some variant of
byte casting but it hasn't been implemented yet.

rather later on PR something that works than a half-baked solution.

Andrew Champion 71f3aa8b15 Include unknown variant for sample format 
Since it is known that libtiff produces other sample format variants we
do not support, represent these as variants. This also allows returning
the sample formats in errors so that composition of formats and known
and unknown formats are clearly reported.

Andrew Champion a439baa948 Decoder: remove test make wrong assumption 
The byte count for strips is the compressed length. The compressed
length may be larger than the uncompressed length, especially with poor
compression choices (multi-byte samples with packbits) or small images.

Andrew Champion ec0477125f Tags: restore primitive conversions as inherent methods 2020-02-01 18:25:05 +00:00
Andrew Champion eadec8f0b9 Remove most unchecked size/index casts 
Convert most unchecked size/index `as` casts to checked casts with
`TryFrom`, included another top-level error variant.

This has several motivations:
- Making the library as robust as possible, including to platform
differences.
- Unchecked casts are susceptible to breakage during refactorings.
- Preparing for BigTIFF support, which will require the introduction of
generics and associated types for some parts of the de/encoders.
Unchecked primitive casts cannot be bound, while TryFrom can, and
overflowing conversions become more likely.
- Remaining u16 casts may be prone in failure in existing practice and
not just in theory during future changes.
