PDF Booklet Imposer is an offline Linux desktop imposition tool for arranging PDF pages into saddle-stitch duplex booklet spreads and multi-up handout grids ready for double-sided printing without uploading documents externally.

Key Features:

• Saddle-Stitch Booklet Folding Engine: Computes exact 4-multiple padded booklet sheet order [N, 1, 2, N-1, ...] so duplex-printed sheets fold in half to read pages 1 through N in sequence, with interactive front and back spread diagrams rendered via Poppler pdftoppm.
• N-Up Handout Grid & Gutter / Creep: Supports 2-Up Booklet, 2-Up Side-by-Side, 4-Up Grid, 6-Up, and 9-Up handout layouts on A4, A3, or US Letter paper with configurable gutter spacing, outer margins, inner-sheet creep compensation, and optional fold-line guides.
• Imposed Print-Ready PDF Exporter: Produces vector-transformed imposed PDFs via PyPDF2 page transformations or high-DPI QPdfWriter output alongside a structured print sheet guide CSV report.
