## 项目历史与用法

tiff2png is a small command-line converter for turning TIFF images into PNG files. Its official libpng-hosted page describes the main goal as direct TIFF-to-PNG conversion while preserving alpha transparency, scaling information, and user-controlled compression.

### 项目历史

The official page credits Willem van Schaik, Greg Roelofs, and Ralph Giles as authors and presents version 0.92 as the current release. It also records earlier lineage through Willem van Schaik's separate 0.7 offshoot, labelled 0.82, and explains behavioral differences around wildcard batch conversion and overwrite handling.

The project sits close to the PNG ecosystem rather than the modern image-toolkit world: the official page is hosted under libpng's PNG applications area and lists libpng, zlib, libtiff, and IJG JPEG libraries as supporting components.

### 采用历史

The official page lists source tarballs, a GitHub repository, git mirrors, and older platform binaries for systems including SCO OpenServer and 32-bit Windows. That distribution style reflects an older portable C utility that survived through source archives, mirrors, and package-manager formulas.

Homebrew keeps tiff2png available as a narrow utility for users who want one conversion command rather than a full ImageMagick-style suite.

### 使用方式

tiff2png is used for batch conversion, with the official page giving a wildcard example such as converting multiple .tiff files at once. It is especially relevant when users care about preserving transparency while producing PNG output.

For package users, the practical use case is scripted image conversion in build, publishing, archival, or web pipelines where a dedicated TIFF-to-PNG binary is simpler than invoking a larger image-processing framework.

### 为什么软件包爱好者会关心

Its package-nerd significance is mostly historical and practical: it is the sort of small, old-school image utility that package managers preserve because scripts depend on exact command names and behaviors.

The official warning about a related offshoot lacking wildcard support and overwrite checks is a reminder that tiny conversion tools often matter because their edge-case behavior is part of the package contract.

### 时间线
