识别依赖外部 tesseract-ocr 后端,需单独安装;识别非英语内容需另行安装对应语言的 tesseract 语言包;从源码编译的步骤在 wiki 中,README 未直接给出。
从 releases 页面下载安装包,或使用发行版仓库:sudo apt install gimagereader(Debian/Ubuntu 需先添加 ppa:sandromani/gimagereader) 硬件要求按 README 说明
README 未说明硬件要求;识别由 tesseract-ocr 完成,需自行安装该后端。
tesseract-ocr 的 Gtk/Qt 图形前端,让你不用命令行也能批量识别图片和 PDF 文字
基于 Tesseract 的图形界面 OCR 工具,支持扫描仪输入和 PDF 文档处理,方便把图片和扫描件转成可编辑文本。
核心能力
- 从磁盘、扫描仪、剪贴板和截图导入 PDF 与图片
