A low-level library for interacting with PDF files.
This is currently a work in progress.
// Open the PDF document
var document = CosDocument.Open(
File.OpenRead(
"/Users/patrik/input.pdf"));
// Create a new object
var obj = new CosObject(
document.XRefTable.GetNextId(),
new CosDictionary()
{
{ new CosName("/Foo"), new CosInteger(32) },
{ new CosName("/Bar"), new CosString("Patrik") },
});
// Add the created object to the document
document.Objects.Set(obj);
// Get an object from the document and manipulate it
// In this case we know that the object 25:0 exist, but this
// will most certainly crash if you're running this as is.
var other = document.Objects.Get(number: 25, generation: 0);
((CosDictionary)other.Object)[new CosName("Baz")] = new CosString("Hello");
// Change the author of the document
document.Info.Title = new CosString("Wisp test");
document.Info.Author = new CosString("Patrik Svensson");
// Save the document
document.Save(
File.OpenWrite("/Users/patrik/output.pdf"),
CosCompression.Smallest);We're using Cake as a dotnet tool for building. So make sure that you've restored Cake by running the following in the repository root:
> dotnet tool restore
After that, running the build is as easy as writing:
> dotnet cake
