Color Management (PDF)
PDF Color Management
The use of ICC color profiles and output intents in PDF to ensure consistent color reproduction across devices and print workflows.
技术细节
In the PDF specification (ISO 32000-2:2020), color management (pdf) is implemented as a specialized object within the document's object graph. PDF files use a cross-reference table to index every object by byte offset, enabling random access without sequential parsing. This architecture allows color management (pdf) to be read, modified, or extracted independently of other document elements. The binary structure supports incremental saves, where changes append to the file without rewriting existing content.
示例
```javascript
// Color Management (PDF): PDF manipulation example
import { PDFDocument } from 'pdf-lib';
const pdfDoc = await PDFDocument.load(fileBytes);
const pages = pdfDoc.getPages();
console.log(`Pages: ${pages.length}`);
```
