Struct jpegxl_sys::JxlFrameHeader

#[repr(C)]pub struct JxlFrameHeader {
    pub duration: u32,
    pub timecode: u32,
    pub name_length: u32,
    pub is_last: c_int,
}

The header of one displayed frame.

Fields

duration: u32

How long to wait after rendering in ticks. The duration in seconds of a tick is given by tps_numerator and tps_denominator in JxlAnimationHeader.

timecode: u32

SMPTE timecode of the current frame in form 0xHHMMSSFF, or 0. The bits are interpreted from most-significant to least-significant as hour, minute, second, and frame. If timecode is nonzero, it is strictly larger than that of a previous frame with nonzero duration. These values are only available if have_timecodes in JxlAnimationHeader is JXL_TRUE. This value is only used if have_timecodes in JxlAnimationHeader is JXL_TRUE.

name_length: u32

Length of the frame name in bytes, or 0 if no name. Excludes null termination character.

is_last: c_int

Indicates this is the last animation frame.
