WIA / ICA / Sane Direct Scanning

WIA (Windows), ICA (Mac), & Sane Direct (Linux) are application interfaces or drivers included by the operating system that enables software to communicate with imaging hardware such as scanners and digital cameras. When scanning using one of these interfaces, PDF Studio will use our custom scanning dialog that will directly communicate with your scanners that support the WIA, ICA, or Sane Direct interface.


Scanning with WIA/ICA

  1. Go to File Tab > Create > From Scanner
  2. This will open the Scan to PDF options dialog
  3. Select the scanner and the setting you wish to use.
  4. Once you have selected all of your options click on either Preview or Scan
    • Preview - generates a quick preview using the scanning options that will be displayed on the right of the dialog
    • Scan - will use the selected options to scan and then create a new PDF or append the image to an existing PDF depending on the option selected.


WIA / ICA / Sane Direct Scan Settings

Scan to PDF Options

Profile - Allows you to add, edit, or delete scanning profiles

Scanner - The scanner to be used

Source - What scanning input to use when scanning the document/image (i.e. flat bed or feeder)

Duplex - If the scanner supports 2 sided scanning, select this option to scan both sides at the same time.

Color Format - Choose between Black and White, Grayscale, or Color when scanning

Note: If "(Conversion)" is listed next to the color option, then this option is not supported by your device. PDF Studio will convert the scanned image to the selected color space for you as a part of the scanning process.

Page Size - Size of the document being scanned

DPI Resolution - What resolution to use when saving the image into the PDF document. Select a predefined value between 50 - 600 or type in your own custom value up to 1200. When selecting a DPI it's best to follow the below guidelines

Black-and-white documents

    • Lowest acceptable resolution = 200 DPI (equal to “high” fax quality)
    • Conventional resolution = 300 DPI
    • Highest conventional resolution = 600 DPI

Color documents (and color compression)

    • Lowest acceptable resolution = 150 DPI
    • Conventional resolution = 200 DPI
    • Highest conventional resolution = 300 DPI
    • Archive resolution = 600 DPI

Scan more pages: Sets the behavior after the scanning is completed

Brightness - Adjusts the brightness of the scanned document. Increase the value to make the document/image look lighter

Contrast - Adjusts the contrast of the scanned document. This affects the differences between light and dark on the document/image

PDF Options

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

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

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

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.
