ImageGear supports the acquisition of images from TWAIN-compliant devices and from scanners for which there is a driver conformant with the ANSI/AIIM MS61-1996. standard. Note that the AIIM MS61 standard is sometimes known as the "ISIS/MS61" standard, but should not be confused with the "ISIS" scanner driver technology developed by Pixel Translations. This chapter applies only to TWAIN-compliant devices.
