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.

`PhotometricInterpretation`	UINT Format	IEEEFP Format
`WhiteIsZero`	Gray(8\|16\|32\|64)	Gray(32\|64)
`BlackIsZero`	Gray(8\|16\|32\|64)	Gray(32\|64)
`RGB`	RGB(8\|16\|32\|64), RGBA(8\|16\|32\|64)	RGB(32\|64), RGBA(32\|64)
`RGBPalette`
`Mask`
`CMYK`	CMYK(8\|16\|32\|64)	CMYK(32\|64)
`YCbCr`
`CIELab`

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.
