Struct PageTransform 

pub struct PageTransform { /* private fields */ }

Affine transform between pixel space of one rendered bitmap and page space of the page it was rendered from.

Obtained from RenderedPage::transform or PdfPage::transform_for. Plain data: freely Clone/Send/Sync, and independent of any PDFium resource.

Implementations

impl PageTransform

pub fn pixel_width(&self) -> u32

Width in pixels of the bitmap this transform describes.

pub fn pixel_height(&self) -> u32

Height in pixels of the bitmap this transform describes.

pub fn pixel_to_page(&self, p: PixelPoint) -> PagePoint

Maps a pixel-space point to page space.

pub fn page_to_pixel(&self, p: PagePoint) -> PixelPoint

Maps a page-space point to pixel space.

pub fn pixel_rect_to_page(&self, r: PixelRect) -> PageRect

Maps a pixel-space rectangle to a normalized page-space rectangle.

pub fn page_rect_to_pixel(&self, r: PageRect) -> PixelRect

Maps a page-space rectangle to a pixel-space rectangle (top-left + size, with non-negative size).
