To do what?

taihangg commented 2 months ago

To do what? I want to load a pdf file，then remove some pages and save it.

That would be something like:

final tools = PdfTools();

final parsed = PdfDocumentParser(await File('doc1.pdf').readAsBytes());
tools.addPages(parsed, [1, 3, 5, 6, 7]);
final result = tools.save();

final file = File('updated.pdf');
await file.writeAsBytes(result);
