Struct ImageDescriptor 

#[non_exhaustive]
pub struct ImageDescriptor {
    pub left: u16,
    pub top: u16,
    pub width: u16,
    pub height: u16,
    pub local_table_size: usize,
    pub interlaced: bool,
}

An image descriptor: where a frame sits on the canvas and how it is coded.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

left: u16

Left edge, in canvas coordinates.

top: u16

Top edge, in canvas coordinates.

width: u16

Frame width.

height: u16

Frame height.

local_table_size: usize

Entries in the local colour table, or zero if absent.

interlaced: bool

Whether the frame’s pixels are stored interlaced.

Implementations

impl ImageDescriptor

pub fn parse(bytes: &[u8; 9]) -> Result<Self>

Errors

Returns PixelsError::Malformed if the frame has no pixels.
