Struct ImageXObject 

pub struct ImageXObject {
    pub width: u32,
    pub height: u32,
    pub color_space: String,
    pub bits_per_component: u8,
    pub filter: String,
    pub data: Vec<u8>,
}

PDF Image XObject representation

Fields

width: u32

Image width in pixels

height: u32

Image height in pixels

color_space: String

Color space (DeviceRGB, DeviceGray, etc.)

bits_per_component: u8

Bits per component (typically 8)

filter: String

Filter name (DCTDecode for JPEG, FlateDecode for PNG)

data: Vec<u8>

Raw image data (JPEG data for DCTDecode, compressed for FlateDecode)

Implementations

impl ImageXObject

pub fn from_image_info(info: &ImageInfo) -> Result<Self>

Create an XObject from ImageInfo

pub fn from_jpeg(jpeg_data: &[u8]) -> Result<Self>

Create an XObject from JPEG data

JPEG images can be embedded directly in PDF using the DCTDecode filter, which allows the raw JPEG data to be used without decompression.

pub fn from_png(png_data: &[u8]) -> Result<Self>

Create an XObject from PNG data

PNG images require decompression and recompression with FlateDecode.

pub fn to_pdf_stream(&self, object_id: u32) -> String

Generate the PDF XObject dictionary and stream

pub fn stream_data(&self) -> &[u8]

Get the stream data

pub fn stream_end() -> &'static str

Get the stream end marker

Trait Implementations

impl Clone for ImageXObject

fn clone(&self) -> ImageXObject

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageXObject

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
