Enum PixelFormat 

pub enum PixelFormat {
    Gray8,
    Rgb8,
    Cmyk8,
    Rgba8,
    Mask1,
}

How the bytes handed to crate::EditDoc::embed_image are laid out.

The oracle takes a bitmap object and reads the format back off it; here the caller states it, because what arrives is loose bytes rather than a bitmap that knows its own shape.

Variants

Gray8

One eight-bit grey sample per pixel, /DeviceGray.

Rgb8

Three eight-bit samples per pixel, /DeviceRGB.

Cmyk8

Four eight-bit samples per pixel, /DeviceCMYK.

Rgba8

Four eight-bit samples per pixel; the fourth becomes a /DeviceGray /SMask and the first three the image’s own /DeviceRGB samples.

Mask1

One bit per pixel, rows padded to a byte, written as an /ImageMask.

A set bit paints, which is the sense /Decode [1 0] gives a stencil mask; see crate::EditDoc::embed_image.
