Struct ClipMargins 

Source 
pub struct ClipMargins(/* private fields */);
Expand description

Clip margins in points: left, top, right, bottom.

A validated newtype rather than a bare array, for two reasons. f64 is not Eq – NaN is not equal to itself – so a bare [f64; 4] on ExtractOptions cost the options their Eq, which is public API a caller may compare or key on. And a margin is a distance into the page: negative or non-finite is a mistake in the call, caught by ClipMargins::new rather than read as a rectangle.

Implementations§

Source§

impl ClipMargins

Source

pub fn new( left: f64, top: f64, right: f64, bottom: f64, ) -> Result<Self, OptionsError>

[left, top, right, bottom] in points. Each side must be finite and at least zero; anything else is an OptionsError::InvalidClipMargins naming the side.

-0.0 is normalised to 0.0, so margins that compare equal as floats compare equal here too.

Source

pub fn as_array(&self) -> [f64; 4]

The margins as [left, top, right, bottom] in points.
