Result of decoding

Fields§

§width: u32

Width of the image

§height: u32

Height of the image

§intensity_target: f32

Upper bound on the intensity level present in the image in nits

§min_nits: f32

Lower bound on the intensity level present in the image

§orientation: Orientation

Orientation

§num_color_channels: u32

Number of color channels per pixel without alpha channel, from metadata

§has_alpha_channel: bool

Whether the image has an alpha channel, from metadata

§intrinsic_width: u32

Intrinsic width of the image. Applications are advised to resample the decoded image to the intrinsic dimensions

§intrinsic_height: u32

Intrinsic height of the image. Applications are advised to resample the decoded image to the intrinsic dimensions

§icc_profile: Option<Vec<u8>>

ICC profile
