Basic Option: This option is always displayed.
Output | PDF file name
This specifies the name of the PDF file to hold the cropped and processed images.
In addition to VueScan writing a specific file name, it can also automatically name your
files in three ways by placing special characters in the filename. See the beginning of
this section for information on how to use this auto-numbering feature.
The default setting of this option is "@.pdf", which is expanded to
"Scan-YYMMDD-0001+.pdf".
Basic Option: This option is displayed whenOutput | PDF file (p. 84) is set.
Output | PDF size reduction
You can use this option to write files with a reduced number of pixels. For instance, if
size reduction is set to 3, then every 3x3 block of pixels in the image will be written as a
single pixel, which is the average of these 9 pixels.
This option will reduce the resolution and size of the file produced. These values will be
displayed in the status area at the bottom of the VueScan window.
However, this option produces better results than reducing the resolution of the scan,
as the averaging of multiple pixels results in a similar noise reduction benefit as
multi-sampling. See Input | Number of samples (p. 59)and Input | Number of passes
(p. 59).
Advanced Option: This option is displayed whenOutput | PDF file (p. 84) is set.
Output | PDF multi page
If set, this option will cause VueScan to create multi-page PDF files. Each scan will be
added as a new page.
This option is useful when you are scanning documents and want all pages stored in a
single file.
Basic Option: This option is displayed whenOutput | PDF file (p. 84) is set.
Output | PDF file type
This option describes the resolution of the cropped PDF file, in bits per pixel. For PDF
files, only 1 bit per sample and 8 bits per sample images are written, and 1 sample per
pixel and 3 samples per pixel images are written.
Advanced Option: This option is displayed whenOutput | PDF file (p. 84) is set.
Output | PDF compression
