Struct png::decoder::SubframeInfo

struct SubframeInfo {
    width: u32,
    height: u32,
    rowlen: usize,
    current_interlace_info: Option<InterlaceInfo>,
    interlace_info_iter: InterlaceInfoIter,
    consumed_and_flushed: bool,
}

The subframe specific information.

In APNG the frames are constructed by combining previous frame and a new subframe (through a combination of dispose_op and overlay_op). These sub frames specify individual dimension information and reuse the global interlace options. This struct encapsulates the state of where in a particular IDAT-frame or subframe we are.

Fields

width: u32

height: u32

rowlen: usize

current_interlace_info: Option<InterlaceInfo>

interlace_info_iter: InterlaceInfoIter
