Struct PdfiumBitmap

pub struct PdfiumBitmap { /* private fields */ }

Rust interface to FPDF_BITMAP

Implementations

impl PdfiumBitmap

pub fn empty( width: i32, height: i32, format: PdfiumBitmapFormat, ) -> PdfiumResult<Self>

Creates a new PdfiumBitmap with the given width, height and PdfiumBitmapFormat.

pub fn fill(&self, color: &PdfiumColor)

Fills this entire PdfiumBitmap with the given PdfiumColor.

pub fn width(&self) -> i32

Returns the width of the image in the bitmap buffer backing this PdfiumBitmap.

pub fn height(&self) -> i32

Returns the height of the image in the bitmap buffer backing this PdfiumBitmap.

pub fn format(&self) -> PdfiumBitmapFormat

Returns the pixel format of the image in the bitmap buffer backing this PdfiumBitmap.

pub fn as_raw_bytes<'a>(&self, lib: &'a PdfiumGuard) -> &'a [u8]

Returns an immutable reference to the bitmap buffer backing this PdfiumBitmap.

This function does not attempt any color channel normalization.

pub fn as_rgba_bytes(&self) -> PdfiumResult<Vec<u8>>

Returns an owned copy of the bitmap buffer backing this PdfiumBitmap as RGBA.

Normalizing all color channels into RGBA irrespective of the original pixel format.

pub fn as_image(&self) -> PdfiumResult<DynamicImage>

Returns a copy of this a bitmap as a DynamicImage::ImageRgba8

pub fn save(&self, path: &str, format: ImageFormat) -> PdfiumResult<()>

Saves this bitmap to the given path.

As the underlying image contains an alpha channel, the ImageFormat needs to support it.
