Beware this is a WIP in its early stages!
The goal of this project is to have a lib that allows you to programmatically read from (and possibly write to) PDF files. It is meant as a low-level PDF file editor API.
Basic PDF info:
const pdf = pdfhacker('test.pdf');
> console.dir(pdf.version);
{
major: 1,
minor: 5
}
Simple text replacement:
pdf.replace('foo', 'bar').saveTo('out.pdf');
Will replace all occurrences of foo
with bar
, finally saving to file out.pdf
.
Chaining:
pdf
.replace('foo', 'bar')
.replace(/\d{3}/, '456')
.saveTo('out.pdf');
Will replace all occurrences of foo
with bar
and will also replace all 123
with 456
, finally saving to file out.pdf
.
Display object tree:
> pdf.dumpTree();
Root
|- Catalog
|- Page 1
|- Page 2
...
Change specific objects:
pdf('/Root/Catalog/Page 1/Text')[0].val('first text object will be affected');
pdf('/Root/Catalog/Page 1/Text').val('all page 1 text objects will be affected');
