There are two automation features in ReaJPEG: Windows integration and command-line usage capability. Windows integration ReaJPEG can integrate itself into Windows Explorer right-click context menu for graphic file formats. Windows integration can be enabled (or disabled) from the "Options" menu of ReaJPEG. You can also adjust output settings for the integrated convertion. Most of the time just accepting the defaults is enough. Command-line usage You can use ReaJPEG as a command-line (console) utility: call it in command files (*.bat, *.cmd) or invoke it during console sessions. Here is the syntax for the ReaJPEG command-line usage. reajpeg /batch filesList [/format jpegSettings] [/proc processings] [/name namingTemplate] filesList - path to the file that lists input images jpegSettings - path to the file that contains JPEG format settings processings - path to the file that contains image processings namingTemplate - path to the file that contains a naming template Command-line troubleshooting Some non-standard command shells can prevent you from using ReaJPEG in command-line mode, launching its user interface no matter what parameters are passed. If you encounter this issue try calling ReaJPEG executable directly as 'reajpeg.com'. If you need to explicitly launch ReaJPEG in user interface mode you should use 'reajpeg.exe'. Important notice Automation features are available in ReaJPEG Pro only. ReaJPEG online help file [an error occurred while processing the directive]
