A.12.10.2 Format Control 2

A.12.10.2.1 Auto margin
The Auto margin control detects the edges of a document and cuts it out of the scanned
image.
If the value (in pixels) is negative, the resulting image will be smaller than the document.
This is helpful to remove unwanted borders from the image.
If the value is positive some of the background will remain in the scanned image.
A.12.10.2.2 Auto density
The Auto density function detects the edges of a document only if they are surrounded
by a dark background.
This control specifies the density level used to decide whether a pixel belongs to the
background or not. A value of 40 is the proper setting in most cases.
Note: When scanning very dark documents, it could be necessary to vary this value to
detect the correct document dimension with the format setting Auto (see chapter
A.12.10.1).
A.12.10.2.3 Auto skew
The image of the scanned area will be deskewed before it is displayed.
Auto skew enables the deskew function and defines the maximum angle of the document
to be deskewed.
Chapter A.12.4 gives information about the buttons
Chapter A.12.3 gives information concerning the help function, which is activated by the
Question Mark symbol.
