项目历史

The original project was hosted on Google Code as pdf2image with Subversion source hosting. Google Code archive metadata records the project as having source, a GPL-2 license, and a later move to the FlexPaper GitHub repository.

The 0.53 source and Windows executable were published in January 2012 according to the official Google Code archive downloads metadata. That 0.53 line is the same major historical release packaged by Homebrew for the command-line formula.

采用历史

PDF2Image was tied to FlexPaper and FlowPaper-style document viewing workflows, where pre-rendering PDF pages to images or extracting text metadata was useful for web display pipelines. In package-manager culture it remains a small compatibility package for users who need this older Ghostscript/XPDF-based converter rather than the unrelated modern Python package with the same name.

使用方式

The archived official description documents a pdf2image command accepting a PDF input and optional XML output, with flags for first and last page, JSON output, compression, zoom, image device, encoding, owner password, and user password.

Package users should treat this as the historical C/C++ PDF2Image tool, not the Python pdf2image wrapper around Poppler. Its runtime expectations center on Ghostscript and FreeType.

为什么软件包爱好者会关心

The package is a naming trap: Homebrew's pdf2image formula tracks the old Google Code/FlexPaper tool, while most contemporary search results point to the Python project. Correct curation prevents users and automated tooling from mixing two unrelated packages with different languages, dependencies, licenses, and CLIs.
