This assumed that a `read` would succeed for the full length, thus interpreting in a subsequent call some data bits as a header. For instance, consider 77 bytes of literal were left and a buffer of 1024 bytes was provided. Then the `read` call might return 60 which was ignored and assumed to be 77. Thus the next 17 bytes of literal data were instead interpreted as a header due to setting `self.count` to 0.
image-tiff
TIFF decoding and encoding library in pure Rust
Supported
Features
- Baseline spec (other than formats and tags listed below as not supported)
- Multipage
- BigTIFF
- Incremental decoding
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.

Fuzzing
This crate uses cargo-fuzz in order to test the image parser.
After installing it with cargo install cargo-fuzz on a nightly rustc, the
fuzzing harness can be run with recommended settings using
cargo fuzz run decode_image -snone -- -timeout=5.
