## プロジェクトの歴史と使われ方

ExactImage is a C++ image-processing library and CLI suite from ExactCODE, created as a faster, more generic alternative to ImageMagick for selected production image workflows.

### プロジェクトの歴史

The official page says ExactCODE began the project in the mid-2000s after finding ImageMagick too CPU-heavy for certain tasks. A C++ prototype reportedly cut processing time to roughly one twentieth of the ImageMagick baseline for the needed workloads.

ExactImage developed through numbered release series. Version 0.2 added a stable SWIG-exported API; 0.3 added per-codec accelerated rotation, flipping, scaling, color conversion, and on-demand decoding; 0.5 added open-source barcode recognition and faster pixel iteration; 0.6 rewrote the PDF codec and introduced hocr2pdf for searchable PDFs.

### 採用の歴史

The project page explicitly mentions deployment in production solutions by partner companies and lists distribution packaging for T2 SDE, FreeBSD ports, Debian, and Ubuntu.

Its adoption story is strongest in scanner, OCR, barcode, and document-processing pipelines rather than desktop image editing.

### 使われ方

The econvert command is the ImageMagick convert-like frontend for reading images, applying operations, and writing outputs. The page documents pipelines such as scaling, rotating JPEGs losslessly, changing color spaces, and producing thumbnails.

Other included tools include edentify for image identification, hocr2pdf for searchable PDF generation from hOCR input, bardecode for barcode recognition, and edisplay for image viewing.

### パッケージ好きにとっての重要性

ExactImage is interesting because it bundles several specialized document-image tools around a performance-oriented C++ library: conversion, identification, barcode recognition, and OCR-to-PDF assembly.

It also represents an older open-source style: project homepage documentation, SVN trunk, release snapshots, and distro packages instead of a GitHub-centered workflow.

### タイムライン

- Mid-2000s: ExactCODE started the C++ prototype after reviewing ImageMagick performance.
- 0.2 series: Stable external SWIG API introduced.
- 0.3 series: Accelerated JPEG-oriented operations and on-demand decoding added.
- 0.5 series: Barcode recognition and faster pixel iteration added.
- 0.6 series: PDF codec rewritten and hocr2pdf introduced.
- 0.8 series: Multiple images per file supported in TIFF and econvert.

### Related projects

- The project page positions ExactImage as a possible alternative to ImageMagick for selected image-processing tasks.
- It embeds dcraw code for camera RAW support and compares fast JPEG scaling with EPEG.
