PDF Watermark Stamper

PDF Watermark Stamper is a desktop document stamping utility for adding
custom text watermarks, transparent PNG logo overlays, confidential ribbon
labels, date stamps, and sequential Bates numbering to PDF documents on Linux.
It combines poppler page rendering with vector PDF overlay generation and
clean page merging without flattening selectable document text.

Key Features:
- Text & Logo Watermark Designer: Configure diagonal, horizontal, or tiled
text watermarks and transparent PNG logo overlays with opacity, rotation
angle (-90 to 90 degrees), font size, color, and page targeting (All, Odd,
Even, First page, or custom page ranges) with live PDF page preview.
- Bates & Date Stamp Designer: Generate vector overlay PDFs with formatted
date stamps, classification ribbon banners, and sequential Bates numbering
(such as PREFIX-0001) merged cleanly onto document pages.
- Batch PDF Folder Stamper: Queue multiple PDF files for automated watermarking
or Bates stamping with verified output page counts and CSV log export.
