v0.12.0

Features:

• Add compression of pre-compressed frame data, via Encoder::write_lzw_pre_encoded_frame.
• The color_quant dependency is now optional. Turning it off disables some interfaces that would internally build quantization tables. The generic implementation of creating such tables can be prohibitively costly compared to specialized algorithms in some use cases.

Optimization:

• Avoid some allocations in by replacing flat_map argument with arrays

v0.11.4

Bufixes:

• Fix decoding confusing superfluous image data from previous frames with current frame data.
• Bump minimum required version of weezl.

Features:

• Add Encoder::{get_ref, get_mut, into_inner} to access underlying stream.

v0.11.3

Bugfixes:

• Fix panic while decoding some images, has no precise cause in the file.
• Warn about set_extensions being unimplemented...

Features:

• Added StreamingDecoder::version to query the precise version of the standard used for encoding the file. This is merely a hint.
• Added DecodeOptions::allow_unknown_blocks to skip over unknown or unspecified block kinds.

Optimization:

• Frame::from_rgba now recognizes when less than 256 colors are being used, dynamically skipping the quantization phase.
• Encoding image chunks is faster and simpler

v0.11.2

• Fix panic when LZW code size is invalid
• Added option to omit check for lzw end code

v0.11.1

• Frames out-of-bounds of the screen descriptor are again accepted by default.
• Added DecodeOptions::check_frame_consistency to turn this validation on.

v0.11

• Rename Reader to Decoder.
• Reworked Decoder into DecodeOptions.
• The decoding error is now opaque and no longer allocates a string. Adding more information or more error conditions is forward compatible.
• Replace the lzw decoder with weezl, up to +350% throughput.
• The dysfunctional C-API has been (temporarily?) removed
  • It may get reintroduced as a separate crate at some point
• Added a std feature. It must be active for now.
