How the imageout keyword affects processing
The line-data transform converts image formats (IM1) in the input file, in overlays, and in page segments to uncompressed IOCA format, if line2afp imageout=ioca keyword and value is specified (the default). An uncompressed IOCA image might use a significantly higher number of bytes than an IM1 image and might take more processing time to convert, especially for shaded or patterned areas. Although IOCA is the MO:DCA-P standard for image data, and some data stream receivers might require it, all products might not accept IOCA data. All software products from the Ricoh do, however, accept IOCA data as well as IM1 image data.
We recommend that you specify imageout=asis, unless you have a specific requirement for IOCA images.
