Enum ImageSource 

enum ImageSource {
    Raster(DynamicImage),
    Svg(ExternalXObject),
}

Enum representing either a raster image or a vector SVG image.

This enum allows the Image struct to handle both raster formats (PNG, JPEG, etc.) and SVG vector graphics without rasterization, leveraging printpdf’s native SVG support.

Variants

Raster(DynamicImage)

A raster image loaded from formats supported by the image crate.

Svg(ExternalXObject)

A vector SVG image parsed by printpdf as an ExternalXObject.

Implementations

impl ImageSource

fn intrinsic_size(&self, dpi: Option<f32>) -> Size

Returns the intrinsic dimensions of the image in millimeters at the default DPI.

For raster images, dimensions are calculated from pixel count and DPI. For SVG images, dimensions are extracted from the ExternalXObject width and height.

Arguments

• dpi - Optional DPI override for raster images. Defaults to 300 DPI if not specified.

Returns

A Size struct containing the width and height in millimeters.

fn is_svg(&self) -> bool

Checks if this image source is an SVG.

Returns

true if this is an SVG image, false otherwise.

Trait Implementations

impl Clone for ImageSource

fn clone(&self) -> ImageSource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
