What it is

The owned image every lib-image format decodes to and encodes from.

An Image is channels interleaved samples per pixel, rows top to bottom, straight (not premultiplied) alpha. Integer samples are display-referred (sRGB coded for color); float samples are scene-linear, as OpenEXR stores them. Half floats are kept as their IEEE 754 binary16 bits (f16_to_f32, f32_to_f16) since Rust's f16 is not stable.

Crate	Repository	As	What it is
`kinogaki-exr-format`	OpenEXR	normal	OpenEXR, a format plugin: an EXR file reads as one standard `Image`, every part's channels its layers, and an Image writes as one EXR, Cryptomatte included.
`kinogaki-jpeg-format`	JPEG	normal	JPEG, a format plugin: a JPEG reads as one standard `Image` as the file holds it, and an Image writes as one baseline JPEG.
`kinogaki-png`	lib-image	normal	PNG images (ISO/IEC 15948, W3C PNG Third Edition) over `kinogaki_deflate`.

Modules

half (private)IEEE 754 binary16 conversions, exact both ways: every half is a float, and a float rounds to the nearest half, ties to even, overflowing to infinity; NaNs stay NaNs (quiet, top payload bits kept).100 lines
srgb (private)The sRGB transfer curve (IEC 61966-2-1) from linear floats to 8-bit codes, rounded to nearest: code n covers the linear values between the decodings of n - 0.5 and n + 0.5, so a binary search over those 255 boundaries gives the exact rounding without a ...50 lines
