Struct ImageContext 

pub struct ImageContext<'a> {
    pub preceding_text: Option<&'a str>,
    pub following_text: Option<&'a str>,
}

Text surrounding the image, for understand_image’s description branch — a caption-less photo described with “a bar chart” is far less useful than one described with the surrounding paragraph’s subject folded in.

Both fields are optional and independent: a page boundary may have preceding text but no following text (last image on a page) or vice versa.

Fields

preceding_text: Option<&'a str>

Text immediately before the image (same page, or the previous page’s last paragraph at a page boundary).

following_text: Option<&'a str>

Text immediately after the image (same page, or the next page’s first paragraph at a page boundary).
