Struct JxlFrameHeader 

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

The header of one displayed frame or non-coalesced layer.

Fields

duration: u32

How long to wait after rendering in ticks. The duration in seconds of a tick is given by JxlAnimationHeader::tps_numerator and JxlAnimationHeader::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 JxlBool::True. This value is only used if have_timecodes in JxlAnimationHeader is JxlBool::True.

name_length: u32

Length of the frame name in bytes, or 0 if no name. Excludes null termination character. This value is set by the decoder. For the encoder, this value is ignored and JxlEncoderSetFrameName is used instead to set the name and the length.

is_last: JxlBool

Indicates this is the last animation frame. This value is set by the decoder to indicate no further frames follow. For the encoder, it is not required to set this value and it is ignored, JxlEncoderCloseFrames is used to indicate the last frame to the encoder instead.

layer_info: JxlLayerInfo

Information about the layer in case of no coalescing.
