Struct ContentInlineImage 

Source
pub struct ContentInlineImage {
    pub image: PdfInlineImage,
    pub ctm: Transform2D,
    pub clip: Option<Path>,
}
Expand description

One BI … ID … EI inline-image event surfaced by the content-stream walker (ISO 32000-1 §8.9.7). Unlike an Image XObject (which is named and resolved through /Resources /XObject), an inline image carries its dictionary + payload directly in the content stream, so the walker is the only place it can be observed with the correct graphics-state context.

The walker does NOT decode the payload into pixels — that belongs to the image pipeline. It captures the resolved PdfInlineImage (dictionary + filter-peeled payload, per [crate::reader::inline_images]) together with the placement context that §8.9 / §8.7.3.4 require to position it:

  • ctm — the composed current transformation matrix at the BI. An inline image is painted into the unit square 0 ≤ x,y ≤ 1 in image space, mapped to user space by the CTM (§8.9.5.1), so ctm is exactly the placement matrix.
  • clip — the most recent W/W*-committed clip path in force, or None. The image is subject to it (§8.5.4).

Fields§

§image: PdfInlineImage

The resolved inline image — dictionary fields (width, height, colour space, bits-per-component, terminal codec filter, image-mask flag) plus the wrapping-filter-peeled payload.

§ctm: Transform2D

Composed current transformation matrix at the moment of the BI operator. Maps the unit-square image space to user space (§8.9.5.1).

§clip: Option<Path>

Active clip path (most recent W/W* commit in the live q frame), or None when no clip is in force (§8.5.4).
