About

PascalSane provides pascal bindings for the libsane library, enabling Lazarus and FreePascal applications to access scanners under Linux.

Principal operations :

  • list available scanners
  • list options for a specified scanner
  • set options for a scanner
  • capture scanner input in PNM format

The download contains the libsane bindings and a unit saneutils.pas which provides some simple functions for manipulating scanner data. It also contains a demonstration Lazarus application, which contains examples of operations that can be performed using libsane.
