Crate hpvca 

Structs

Cicp

ColorMetadata

How the output color space is described in the file.

ContentLightLevel

HDR content light level (CTA-861.3 / ISOBMFF clli): the maximum content light level (MaxCLL) and maximum frame-average light level (MaxFALL), both in cd/m² (nits). Written as the ContentLightLevelBox.

EncodeConfig

Encoder configuration shared by all entry points.

Metadata

All optional metadata passed to the encoder, threaded through crate::EncodeConfig.

Yuv

Planar YCbCr image

Enums

BitDepth

ChromaFormat

Chroma subsampling mode.

EncodeError

MatrixCoefficients

CICP matrix coefficients for RGB→YCbCr (ISO/IEC 23091-2 Table 4).

Orientation

Primaries

CICP color primaries (ISO/IEC 23091-2 Table 2).

TransferFunction

CICP transfer characteristics (ISO/IEC 23091-2 Table 3).

Functions

encode_gray

Encode a packed 8-bit grayscale image to HEIC (monochrome, no chroma).

encode_gray10

Encode a 10-bit grayscale image to HEIC.

encode_gray12

Encode a 12-bit grayscale image to HEIC.

encode_gray_alpha

Encode a packed 8-bit grayscale + alpha image to HEIC. Alpha is discarded. Use encode_gray_alpha_with_alpha to preserve it.

encode_gray_alpha10

Encode a 10-bit grayscale + alpha image to HEIC. Alpha is discarded.

encode_gray_alpha12

Encode a 12-bit grayscale + alpha image to HEIC. Alpha is discarded.

encode_gray_alpha10_with_alpha

Encode a 10-bit grayscale + alpha image to HEIC with a separate alpha auxiliary image.

encode_gray_alpha12_with_alpha

Encode a 12-bit grayscale + alpha image to HEIC with a separate alpha auxiliary image.

encode_gray_alpha_with_alpha

Encode a packed 8-bit grayscale + alpha image to HEIC with a separate alpha auxiliary image per ISO/IEC 23008-12.

encode_rgb

Encode a packed 8-bit RGB image to HEIC.

encode_rgb10

Encode a 10-bit RGB image to HEIC.

encode_rgb12

encode_rgba

Encode a packed 8-bit RGBA image to HEIC. Alpha is discarded. Use encode_rgba_with_alpha to preserve it.

encode_rgba10

Encode a 10-bit RGBA image to HEIC. Alpha is discarded.

encode_rgba12

Encode a 12-bit RGBA image to HEIC. Alpha is discarded.

encode_rgba10_with_alpha

encode_rgba12_with_alpha

Encode a 12-bit RGBA image to HEIC with a separate alpha auxiliary image.

encode_rgba_with_alpha

Encode a packed 8-bit RGBA image to HEIC, writing alpha as a separate monochrome auxiliary image per ISO/IEC 23008-12.

encode_yuv

Encode pre-converted planar YCbCr directly, skipping the RGB→YCbCr step.
