gscan2pdf介绍 这里要说明的是，gscan2pdf可能会显得老旧，但是gscan2pdf相比Simple Scan、Skanlite、GIMP XSane、GIMP QuiteInsane仍然包括了一些更实用的功能。除了以各种图像格式（JPEG、PNG 和 TIFF）保存扫描外，gscan2pdf还可以将它们保存为PDF或DjVu文件。你可以在单击“扫描”按钮之前设置扫描的分辨率，无论是黑白、彩色还是纸张大小，每当你想要更改任何这些设置时，都可以进入gscan2pdf的首选项。你还可以旋转、裁剪和删除页面。gscan2pdf的这些设置会给你带来更多的灵活性。
下载地址
安装方法 如果使用的是Ubuntu系统，可以使用下面的PPA获取最新版本： sudo apt-add-repository ppa:jeffreyratcliffe/ppa 从终端安装的命令： sudo apt-get update sudo apt-get install gscan2pdf 附：Building gscan2pdf from source Having downloaded the source either from a Sourceforge file release, or from the Git repository, unpack it if necessary with tar xvfz gscan2pdf-x.x.x.tar.gz cd gscan2pdf-x.x.x perl Makefile.PL, will create the Makefile. make test should run several hundred tests to confirm that things will work properly on your system. You can install directly from the source with make install, but building the appropriate package for your distribution should be as straightforward as make debdist or make rpmdist. However, you will additionally need the rpm, devscripts, fakeroot, debhelper and gettext packages.
用法 1.Scan one or several pages in with File/Scan 2.Create PDF of selected pages with File/Save
参数 gscan2pdf has the following command-line options: --device=<device> Specifies the device to use, instead of getting the list of devices from via the SANE API. This can be useful if the scanner is on a remote computer which is not broadcasting its existence. --help Displays this help page and exits. --log=<log file> Specifies a file to store logging messages. --(debug|info|warn|error|fatal) Defines the log level. If a log file is specified, this defaults to 'debug', otherwise 'warn'. --import=<PDF|DjVu|image> Imports the specified file --version Displays the program version and exits.
