One of the leading standards for exchanging images on the Internet is the efficient compression technology developed by the Joint Photographic Experts Group (JPEG), which can handle images with up to 16 million colors. JPEG massively reduces storage space through lossy compression. However, beyond a compression factor of about 10, artifacts (optical noise) might appear. JPEGs are recommended for photos but not for graphics and diagrams. The default file extension is .jpg.
JPEG factor
Sets the compression factor for JPEG. The default value is 75.
Ignore blank pages
Turn this function on (checkbox ticked) if you wish to omit blank pages from export.
Ignore monochrome pages, Ignore gray scale pages, Ignore color pages
Specifically applies to multistream mode. If any of these three filters are set to on (checkbox ticked), then this export option is turned off for the respective page type. Please note that combining all three options Ignore monochrome pages, Ignore gray scale pages and Ignore color pages will effectively turn off execution all together, since there are no images left to process.
File extension
You may change the default file extension to your liking. Please note, however, that this may interfere with other applications and your operating system.
Subdirectory (separate option)
Exporting into a file system may be performed using a dynamic directory structure, which can be constructed from a multitude of variables.
You may use any of the available variables (such as date/time, calendar week, batch counter and/or fixed text) for generating the subdirectory. For more and detailed information on variables please refer to the separate section on Variables, in the Appendix.
Filename (separate option)
Filenames may be dynamically composed from a multitude of strings and variables.
You may use any of the available variables (such as date/time, calendar week, batch counter and/or fixed text) for generating the file name. For more and detailed information on variables please refer to the separate section on Variables, in the Appendix.
Please note: Since this export format does not support multi-page export (i.e. a separate file must be created, for each of the images), Image counter has been made a preset option. For further information please refer to the Appendix, section Single- and multipage export.
Image processing (separate option)
In addition to performing image processing on incoming images, it is also possible to modify output files. Each export format may be individually processed using a subset of the full toolset described in the section on Image processing. Use this option if one or more export formats need to be modified selectively.
The tools available during export are as follows:
Border removal, Color conversion, Deskew, Despeckle, Flip Image, Frame page, Invert, Line removal, Punch hole removal, Rotate Image, Scale resolution.
