Scan report 157 - EPSON DS-770

1. long-paper-mode
   • initial_value: 0
   • capabilities: <class 'pyinsane2.sane.rawapi.SaneCapabilities'> :[ Soft_select, Soft_detect,]
   • constraint: None
   • type: <class 'pyinsane2.sane.rawapi.SaneValueType'> : Boolean (0)
   • title: Long Paper Mode
   • size: 4
   • desc: Select this mode if you want to scan documents longer than what the ADF would normally support. Please note that it only supports automatic detection of the document height.
   • contrainttype: <class 'pyinsane2.sane.rawapi.SaneConstraintType'> : None (0)

   • constraint: ['JPEG']
   • type: <class 'pyinsane2.sane.rawapi.SaneValueType'> : String (3)
   • title: Transfer Format
   • size: 5
   • desc: Selecting a compressed format such as JPEG normally results in faster device side processing.

   • constraint: None
   • type: <class 'pyinsane2.sane.rawapi.SaneValueType'> : Boolean (0)
   • title: Force Extent
   • size: 4
   • desc: Force the image size to equal the user selected size. Scanners may trim the image data to the detected size of the document. This may result in images that are not all exactly the same size. This option makes sure all image sizes match the selected area. Note that this option may slow down application/driver side processing.
