Struct DeviceRect 

pub struct DeviceRect { /* private fields */ }

A rectangle of whole device pixels, measured from the top-left corner of the page’s full device box (the box the render transform maps the page to, whose size is the whole-page render’s pixmap size).

Validated at construction: neither side is zero, neither exceeds MAX_TARGET_DIMENSION — the largest pixmap a backend allocates — and the far edges fit in a u32. Whether it lies inside a particular page’s device box is the render’s to check, since only the render knows the box.

use pdfrum_render::DeviceRect;

let tile = DeviceRect::new(512, 256, 256, 256)?;
assert_eq!((tile.x(), tile.y(), tile.width(), tile.height()), (512, 256, 256, 256));
assert!(DeviceRect::new(0, 0, 0, 10).is_err());

Implementations

impl DeviceRect

pub fn new(x: u32, y: u32, width: u32, height: u32) -> Result<DeviceRect, Error>

The rectangle with its top-left corner at (x, y) and the given size, in device pixels.

Errors

Error::TargetEmpty when width or height is zero, and Error::TargetTooLarge when either exceeds MAX_TARGET_DIMENSION or when x + width or y + height overflows a u32.

pub fn x(&self) -> u32

The left edge, in pixels from the left of the page’s device box.

pub fn y(&self) -> u32

The top edge, in pixels from the top of the page’s device box.

pub fn width(&self) -> u32

The width in pixels; also the width of the pixmap a render of this rectangle produces.

pub fn height(&self) -> u32

The height in pixels; also the height of the pixmap a render of this rectangle produces.
