Struct Graphic 

pub struct Graphic {
    pub width: u32,
    pub height: u32,
    pub rows: String,
}

A GROB’s picture: width by height pixels, rows the pixels packed one bit each as hex digits (two per byte), every row starting on a byte, the leftmost pixel in the most significant bit, 1 dark: the page’s frame layout, so a picture is drawn like the screen.

Fields

width: u32

Pixels per row.

height: u32

Rows.

rows: String

The packed rows, hex.

Implementations

impl Graphic

pub fn from_packed( width: u32, height: u32, packed: &[u8], ) -> Result<Graphic, Error>

The picture of width by height pixels whose rows are packed as the page’s frame packs them (one bit a pixel, every row starting on a byte, the leftmost pixel in the most significant bit, 1 dark); bits beyond the width are dropped. An error when the size is 0, too large, or packed is not that long.

pub fn to_grob(&self) -> Result<Vec<u8>, Error>

The GROB of this picture, all its nibbles, prolog first: the inverse of graphic (the same layout, wiki: protocols/hp-object-format, “GROB layout”).
