Pages

A PdfPage represents one page of the document. Pages are added in order and rendered in that order.

Adding pages

try (PdfDocument doc = new PdfDocument()) {
    PdfPage page1 = doc.addPage(595, 842);   // A4
    PdfPage page2 = doc.addPage(612, 792);   // Letter

    // Draw on each page independently
    doc.writeTo(new FileOutputStream("output.pdf"));
}

Add as many pages as needed. Pages appear in the PDF in the order they were added.

Page sizes

Dimensions are in PDF units — 1 unit = 1/72 inch (same as a typographic point).

Format	Width	Height
A4	595	842
Letter	612	792
A3	842	1191
A5	420	595
Legal	612	1008

For landscape, swap width and height: doc.addPage(842, 595) gives landscape A4.

Coordinate system

(0, 842) ────────── (595, 842)   ← top of A4
    │                      │
    │                      │
(0,   0) ────────── (595,   0)   ← origin

• Origin (0, 0) is at the bottom-left.
• X increases to the right.
• Y increases upward.
• A typical top margin of 72 units (1 inch) means starting content at y = 770 on A4.

Drawing on a page

All draw calls are made on the PdfPage object:

PdfPage page = doc.addPage(595, 842);

page.drawTextBox(72, 750, 450, 40, "Section Title");
page.drawTextBox(72, 690, 450, 200, bodyText);
page.drawLine(72, 680, 523, 680);
