Lester

Lester, Victor’s cousin, makes raster graphics.

This is a reimplementation of Poppler’s pdftocairo utility program as a Rust library. It loads PDF documents with Poppler and renders (rasterizes) them to in-memory pixel buffers with cairo. It can then export to PNG.

Lester is primarily intended to help test the visual rendering of PDF files generated by Victor. Reimplementing pdftocairo enables skipping the overhead of cross-process communication and image compression/decompression. It also enables extracting (and testing) PDF metadata at the same time as rendering.

Requirements

• Poppler, with its glib wrapper API.
• cairo
• pkg-config, at build time
