Correcting skewed images

Top  Previous  Next

Some devices support image correction if the page has been acquired either slanted to the left/right, or if the page has been placed on the scanner where parts of the page lie outside of the acquisition area.


The commands that correct these errors are as follows:





Please note that with both of these commands, your scanner must have TWAIN support for deskewing and/or overscan processing.  Many devices do not have these options.  To test if your scanner or device has these options, produce a -details log and check for the following information listed below your device's information:





If deskewing is supported, then the value for Device_AutoDeskew will be 1.  


If overscan is supported, then value will be a list of all the available overscan modes, otherwise Unsupported will be the value shown.
