Pdf Viewing

Overview

Use this skill to OCR PDFs with docling and preserve page numbers, rasterize pages into images, or inspect PDF metadata. Always save outputs under a local project directory (default: ./.pdf-artifacts/<pdf-stem>).

Quick Start

1. Create a local venv in the project and install deps as dev dependencies:

   uv venv
   uv add --dev docling typer pymupdf

2. Run the OCR tool:

   uv run python scripts/pdf_tools.py ocr path/to/file.pdf --out-dir ./.pdf-artifacts/<pdf-stem>

3. Run the rasterizer:

   uv run python scripts/pdf_tools.py rasterize path/to/file.pdf --out-dir ./.pdf-artifacts/<pdf-stem>

Tasks

OCR with page tracking

• Command: uv run python scripts/pdf_tools.py ocr <pdf-path>
• Output (default): ./.pdf-artifacts/<pdf-stem>/ocr-pages.json and ocr-pages.txt
• Behavior: Copies the input PDF into the output dir and writes per-page text with page numbers.

Explicit flags

• --out-dir <dir>: output directory (relative paths are rooted at the project root)
• --project-root <dir>: base path for relative output paths
• --copy-pdf / --no-copy-pdf: control whether the input PDF is copied into the output dir
• --pages <ranges>: page ranges like 1-3,5,8-10
• --pages-json <name>: JSON filename for per-page text
• --pages-text <name>: TXT filename for per-page text
• --manifest <name>: manifest filename (default manifest.json)
• --overwrite / --no-overwrite: overwrite existing outputs
• --dry-run: show what would be written

Rasterize to images

• Command: uv run python scripts/pdf_tools.py rasterize <pdf-path>
• Output (default): ./.pdf-artifacts/<pdf-stem>/images/page-0001.jpg (etc.)
• Behavior: Renders each PDF page to an image at the requested DPI.

Explicit flags

• --out-dir <dir>: output directory (relative paths are rooted at the project root)
• --project-root <dir>: base path for relative output paths
• --copy-pdf / --no-copy-pdf: control whether the input PDF is copied into the output dir
• --pages <ranges>: page ranges like 1-3,5,8-10
• --dpi <int>: rasterization DPI
• --format <jpg|png|webp>: output image format
• --quality <1-100>: for jpg/webp
• --images-dir <name>: directory for output images
• --images-manifest <name>: JSON manifest name with image paths
• --manifest <name>: manifest filename (default manifest.json)
• --overwrite / --no-overwrite: overwrite existing outputs
• --dry-run: show what would be written

Inspect metadata

• Command: uv run python scripts/pdf_tools.py inspect <pdf-path>
• Output: writes metadata to stdout and manifest.json unless --no-manifest

Clean artifacts

• Command: uv run python scripts/pdf_tools.py clean <pdf-path>
• Behavior: Removes the artifact directory for the PDF.

Notes

• Keep outputs inside the current project by using the default output directory or a relative --out-dir.
• If docling requires extra OCR backends in your environment, install them before running OCR.

Tools

• scripts/pdf_tools.py: Typer CLI with ocr, rasterize, inspect, and clean commands.
