PDF view spec from a destination array.

Each variant maps to one of the explicit-destination forms in ISO 32000-2 §12.3.2.2.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Xyz

[page /XYZ left top zoom] — position the upper-left corner of the page region at (left, top) and zoom to zoom (1.0 = 100%). None for a coordinate or zoom means “retain the current value”.

Fields

x: Option<f64>

y: Option<f64>

zoom: Option<f64>

Fit

[page /Fit] — fit the entire page in the window.

FitH

[page /FitH top] — fit the page width with the top edge at top.

Fields

y: Option<f64>

FitV

[page /FitV left] — fit the page height with left edge at left.

Fields

x: Option<f64>

FitR

[page /FitR left bottom right top] — fit the rectangle in the window.

Fields

left: f64

bottom: f64

right: f64

top: f64

FitB

[page /FitB] — fit the page’s bounding box in the window.

FitBH

[page /FitBH top] — fit the bounding-box width.

Fields

y: Option<f64>

FitBV

[page /FitBV left] — fit the bounding-box height.

Fields

x: Option<f64>
