Struct ContentInterpreter 

pub struct ContentInterpreter<'a> { /* private fields */ }

PDF content stream interpreter.

Implementations

impl<'a> ContentInterpreter<'a>

pub fn new( resolver: &'a Resolver<'a>, resources: PdfDict, initial_ctm: Matrix, icc_cache: &IccCache, font_provider: Option<FontProvider>, overprint_enabled: bool, ocg_off: &HashSet<u32>, ) -> Self

Create a new interpreter.

pub fn set_page_group_cmyk(&mut self)

Mark this page as having a DeviceCMYK transparency group. DeviceRGB colors will be round-tripped through the ICC CMYK profile to match compositing in CMYK space (produces more muted, accurate colors).

pub fn set_pdfx_cmyk_intent(&mut self)

Mark this document as declaring a PDF/X-style CMYK output intent. Opts the document into the DeviceGray-to-K-only promotion required by GWG 23.0. Plain /Group /CS /DeviceCMYK pages should not call this.

pub fn interpret(self, data: &[u8]) -> Result<DisplayList, PdfError>

Interpret a content stream and return the display list.

pub fn interpret_stream_public(&mut self, data: &[u8]) -> Result<(), PdfError>

Interpret a content stream, keeping the interpreter alive for further use.

pub fn into_display_list(self) -> DisplayList

Consume the interpreter and return the display list.

pub fn unwind_gstate_stack(&mut self)

Unwind any leftover gstate stack entries from unbalanced q/Q. Some PDFs have more q’s than Q’s; pop each entry as if Q were called, restoring clip state at each level so display list clips are correct.

pub fn reset_clip_for_annotations(&mut self)

Reset clip state before rendering annotations. This ensures annotations aren’t affected by clip regions from the page content.

pub fn render_annotation( &mut self, obj_num: u32, gen_num: u16, ) -> Result<(), PdfError>

Render an annotation’s normal appearance stream (/AP /N).
