Struct ImageObject 

pub struct ImageObject {
    pub image: Arc<ImageData>,
    pub matrix: Affine,
    pub is_mask: bool,
    pub oc: Option<Arc<Dict>>,
    pub source: Option<ObjRef>,
}

An image, decoded.

Fields

image: Arc<ImageData>

The pixels, shared with the session cache.

matrix: Affine

The matrix taking the unit square onto the image’s place on the page.

is_mask: bool

Whether the image is a stencil painted with the fill colour.

oc: Option<Arc<Dict>>

The /OC entry from the image XObject’s own dictionary.

An image carries optional-content membership on the XObject rather than through a marked-content sequence, so this is a second, separate place visibility is declared and not a cache of the first. An inline image has no dictionary of its own to declare it in.

source: Option<ObjRef>

The XObject this image was drawn from, when it was a named resource.

The pixels here are decoded, and a regenerated stream must name the undecoded stream a Do can reach — so the reference travels with the object. None for an inline image, which has no indirect object to name and is therefore dropped when its stream is rewritten.
