PDF Oxide

Criação de Anotações

O PDF Oxide oferece suporte à criação de todos os tipos padrão de anotação de PDF. As anotações podem ser adicionadas por meio do FluentPageBuilder (API DocumentBuilder) ou do PageBuilder (API PdfWriter).

Cobertura das bindings (v0.3.38). Os 15 métodos de anotação do DocumentBuilder / FluentPageBuilder — link_url / link_page / link_named, highlight, underline, strikeout, squiggly, nota adesiva, carimbo (14 tipos padrão + personalizado), texto livre e marca d’água (personalizada / DRAFT / CONFIDENTIAL) — estão disponíveis em Rust, Python, Node/TypeScript, C#, Go e WASM. A interface de baixo nível PdfWriter, com formas específicas por método (ink, polygon, polyline, caret, popup, file-attachment, redact), é exclusiva do Rust; nas demais bindings, use o DocumentBuilder ou edite PDFs existentes via Edição de Anotações.

Exemplo Rápido

Rust (DocumentBuilder)

use pdf_oxide::writer::{DocumentBuilder, PageSize, StampType};

let mut builder = DocumentBuilder::new();
builder.page(PageSize::Letter)
    .at(72.0, 720.0)
    .text("Click here for details")
    .link_url("https://example.com")
    .text("Important finding")
    .highlight((1.0, 1.0, 0.0))  // Yellow highlight
    .sticky_note("Review this section carefully")
    .stamp(StampType::Approved)
    .done();

builder.save("annotated.pdf")?;

Rust (PdfWriter)

use pdf_oxide::writer::PdfWriter;
use pdf_oxide::geometry::Rect;

let mut writer = PdfWriter::new();
{
    let mut page = writer.add_letter_page();
    page.add_text("Document text", 72.0, 720.0, "Helvetica", 12.0);
    page.link(Rect::new(72.0, 720.0, 100.0, 12.0), "https://example.com");
    page.highlight_rect(Rect::new(72.0, 700.0, 200.0, 12.0));
    page.sticky_note(Rect::new(300.0, 720.0, 24.0, 24.0), "A note");
    page.finish();
}
writer.save("annotated.pdf")?;

Python

from pdf_oxide import DocumentBuilder, StampType

pdf = (DocumentBuilder()
    .letter_page()
        .at(72, 720).text("Click here for details")
        .link_url("https://example.com")
        .text("Important finding")
        .highlight((1.0, 1.0, 0.0))
        .sticky_note("Review this section carefully")
        .stamp(StampType.APPROVED)
    .done()
    .save("annotated.pdf"))

Node / TypeScript

import { DocumentBuilder, StampType } from "pdf-oxide";

await new DocumentBuilder()
  .letterPage()
    .at(72, 720).text("Click here for details")
    .linkUrl("https://example.com")
    .text("Important finding")
    .highlight([1.0, 1.0, 0.0])
    .stickyNote("Review this section carefully")
    .stamp(StampType.Approved)
  .done()
  .save("annotated.pdf");

C#

using PdfOxide;

DocumentBuilder.Create()
    .LetterPage()
        .At(72, 720).Text("Click here for details")
        .LinkUrl("https://example.com")
        .Text("Important finding")
        .Highlight(1.0, 1.0, 0.0)
        .StickyNote("Review this section carefully")
        .Stamp(StampType.Approved)
    .Done()
    .Save("annotated.pdf");

Go

builder := pdfoxide.NewDocumentBuilder()
builder.LetterPage().
    At(72, 720).Text("Click here for details").
    LinkUrl("https://example.com").
    Text("Important finding").
    Highlight(1.0, 1.0, 0.0).
    StickyNote("Review this section carefully").
    Stamp(pdfoxide.StampApproved).
    Done()
_ = builder.Save("annotated.pdf")

JavaScript (WASM) – atalhos de anotação para PDFs existentes

Os auxiliares legados addLink / addHighlight / addNote continuam funcionando para editar PDFs existentes:

import init, { WasmPdfDocument } from "pdf-oxide-wasm/web";
await init();

const doc = new WasmPdfDocument(bytes);
doc.addLink(0, 100, 200, 300, 50, "https://oxide.fyi");
doc.addHighlight(0, 100, 700, 400, 20);
doc.addNote(0, 50, 750, "Review this section");
const saved = doc.save();
doc.free();

Para anotações criadas no momento da geração a partir do WASM, use o DocumentBuilder (a mesma API do exemplo Node/TS acima).

Tipos de Anotação

Anotações de Texto (Notas Adesivas)

Notas pop-up com vários ícones.

use pdf_oxide::writer::PdfWriter;
use pdf_oxide::annotation_types::TextAnnotationIcon;
use pdf_oxide::geometry::Rect;

let mut writer = PdfWriter::new();
{
    let mut page = writer.add_letter_page();

    // Default note icon
    page.sticky_note(Rect::new(72.0, 720.0, 24.0, 24.0), "Review this section");

    // Comment icon
    page.comment(Rect::new(72.0, 690.0, 24.0, 24.0), "Needs clarification");

    // Custom icon
    page.text_note_with_icon(
        Rect::new(72.0, 660.0, 24.0, 24.0),
        "Important",
        TextAnnotationIcon::Key,
    );

    page.finish();
}

Ícones disponíveis: Note, Comment, Key, Help, NewParagraph, Paragraph, Insert

Equivalente no FluentPageBuilder:

builder.page(PageSize::Letter)
    .at(72.0, 720.0)
    .sticky_note("Review this")
    .sticky_note_with_icon("Important", TextAnnotationIcon::Key)
    .sticky_note_at(300.0, 720.0, "Positioned note")
    .done();

Links de URL e navegação entre páginas internas.

// URL link
page.link(Rect::new(72.0, 720.0, 150.0, 12.0), "https://example.com");

// Internal page link (0-indexed page number)
page.internal_link(Rect::new(72.0, 700.0, 100.0, 12.0), 2);

FluentPageBuilder:

builder.page(PageSize::Letter)
    .at(72.0, 720.0)
    .text("Visit website")
    .link_url("https://example.com")
    .text("Go to appendix")
    .link_page(5)
    .text("Jump to glossary")
    .link_named("glossary")
    .done();

Anotações FreeText

Texto exibido diretamente na superfície da página.

use pdf_oxide::geometry::Rect;

// Basic text box
page.textbox(Rect::new(72.0, 650.0, 200.0, 50.0), "Annotation text");

// Styled text box
page.textbox_styled(
    Rect::new(72.0, 580.0, 200.0, 50.0),
    "Styled text",
    "Courier",
    14.0,
);

// Centered text
page.textbox_centered(Rect::new(72.0, 520.0, 200.0, 30.0), "Centered");

// Callout with leader line
page.callout(
    Rect::new(200.0, 450.0, 150.0, 50.0),
    "Callout text",
    vec![150.0, 430.0, 200.0, 475.0],
);

// Typewriter (borderless text)
page.typewriter(Rect::new(72.0, 400.0, 300.0, 20.0), "Typewriter text");

FluentPageBuilder:

builder.page(PageSize::Letter)
    .freetext(Rect::new(100.0, 600.0, 200.0, 50.0), "Comment text")
    .freetext_styled(Rect::new(100.0, 530.0, 200.0, 50.0), "Styled", "Courier", 14.0)
    .done();
