Struct PageProfile 

pub struct PageProfile {
    pub page: u32,
    pub has_text: bool,
    pub has_visible_text: bool,
    pub image_count: u32,
    pub inline_image_count: u32,
    pub has_vector_graphics: bool,
    pub largest_image_coverage: f64,
}

What one page paints.

Fields

page: u32

1-based page number.

has_text: bool

The page shows at least one non-empty text string, visible or not (an already recognised scan carries an invisible text layer and counts as having text).

has_visible_text: bool

Text is shown in a visible render mode.

image_count: u32

Image XObjects painted (forms followed), inline images counted separately.

inline_image_count: u32

has_vector_graphics: bool

Path painting or shading operators were seen.

largest_image_coverage: f64

Largest painted image area as a fraction of the visible page area, capped at 1.0.

Implementations

impl PageProfile

pub const SCAN_COVERAGE: f64 = 0.5

Minimum PageProfile::largest_image_coverage for a page to count as a scan.

pub fn is_scanned(&self) -> bool

True when the page has no text layer and an image covers at least half of it: the page needs OCR.
