Sane Daemon Scanning

Sane (Linux Only) is a scanning protocol that connects to scanners by providing a standardized interface. SANE only provides an interface with the hardware and displays the options available for each scanner. When scanning using Sane PDF Studio will first launch the scanning application, then once the scanning is complete import the scanned image to complete the Scan to PDF process.

Note: For PDF Studio to connect to the scanner properly, you need to make sure that you have a saned daemon and at least one sane back-end installed. This is required for our scanning library to work properly. Note that this is not requirement for other products such as XSane and Gimp, so it is possible that XSane and Gimp work but PDF Studio doesn’t . For more information on how to setup the saned daemon see Scanning to PDF with Linux on our Knowledge Base.

Go to Convert Tab > From Scanner click on the small down arrow to the right of the scanning button and select "Sane Daemon Scanning".
Choose a scanner from the list and click on the OK button to proceed. If there is an error with the selected scanner, the dialog will appear again with the previously tried scanner highlighted so you can choose a new scanner.
- If the selected scanner had been a default option, you can use this dialog to change the default scanner by selecting the new scanner and checking the "Set default Scanner" option.
When the OK button is pressed, a standard scanning interface will be displayed. This is a separate program that will allow you to adjust the scan settings and then begin the scanning process.
Once the scan has been completed and PDF Studio has received the data from the scanner, PDF Studio will display a dialog box showing some information about the scan and will prompt you for a number of choices to determine how to insert the new image.
Once you've selected the options click OK to then create a new PDF or append the image to an existing PDF depending on the option selected.

Image Info

This sections displays some basic details on the image that was received from your scanners software

PDF Options

Insert At - Where to insert the new image. Choose from the following options:

Beginning Of Document: Inserts the scanned pages before the first page of the currently opened document
Current Location: Inserts the scanned pages in front of the current page being displayed of the currently opened document
End Of Document: Appends the scan at the end of the document.
New Document: Creates a new document using only the scanned pages
Interleave – When scanning multiple images, this option can be used to insert them at every other page. This is especially useful for scanning two-sided documents.
Reverse Interleave: Insert the scan in the current document at every other page in reverse order starting after the last page of the document.
Multiple documents - Use this option to create multiple documents when scanning multiple pages. When selected a dialog will be displayed to set the following options.
- Pages per PDF - Number of pages before creating the next PDF
- File Name Pattern - The file name to be used when creating the PDFs. Each file will have the number of the document appended to the end of the file name
- Save files To - Where to save the created files
- Save as Default - When checked this will make the selected options the default going forward

Page Size - What size to use when creating a new page to hold the image.

Size to Image – The new page will be created the same size as the scanned image.
Same as Document – The new page will be created the same size as the current open document. If the document is empty or if the Insert At choice is set to New Document the new page will be created at the same size as the scanned image.

Compression - What compression to use when saving the image into the PDF document.

JPEG - Lossy compression (recommended compression)
- Quality (for JPEG compression only) – If using JPEG, the compression quality can be adjusted from 1 to 100%.
- - 1 = high compression, very low quality
  - 100 = low compression, very high quality
  - Generally, 80=high quality, 50=medium quality, 20=low quality
Flate - Lossless compression format
JBIG2 B&W - Lossless compression format that only supports B&W color

Auto deskew images - When checked, if the document’s text/images are slanting too far in one direction or is misaligned, PDF Studio will attempt to auto-rotate the document so that the alignment is corrected.

OCR Options

OCR - Create Searchable PDF - Check this to automatically OCR the document after scanning

Language - Language to be used if OCR is selected. Click on "Download OCR Languages" to download additional languages.
