Initial zoom
Fit Height resizes the image (zoom) to fit the height of the program window.
FitToWidth resizes the image (zoom) to fit the width of the program window.
Best Fit returns the best zoom value to stretch the image in the program.
Zoom Filter
ZoomFilter specifies the filter to apply in zoom-in operations.
The fastest way to zoom a picture is to set ZoomFilter to None.
If you need the best quality we suggest: Hermite, Bell, BSpline, Lanczos3, Mitchell, Nearest, Bilinear, Bicubic.
If you need speed we suggest: Triangle, Linear, FastLinear.
For projects (white on black or black on white) we suggest: ProjectBW and ProjectWB.
Window State

Screen units specifies the measurement unit used for displaying image.
Window Size
Specifies the height and width (in pixels) of the form.

When Auto Adjust DPI is checked and last loaded/scanned image has horizontal DPI (dot per inch) not equal to vertical DPI, program resizes the image making DPIX=DPIY.

You can change a Mouse Wheel Actions (scrolling, zooming).
Mouse Wheel Position
If Mouse Wheel Action is Zoom, Wheel Position specifies where the zoom acts.

DPI is DPI (Dots per Inch) in the X-axis.
Color is the type of pixel data that a scanner is capable of acquiring.
Valid values are Black&white, Gray scale and full RGB (24 bit).
Feeder Enabled enables the feed loader mechanism when present. Use this property to disable the feed loader.
If Auto Feed is checked, the scanner will automatically feed the next page from the document feeder.
If Duplex Enabled is checked, the scanner scans both sides of a paper; otherwise, the scanner will scan only one side.
Use this property to enable/disable duplex mode.
Language tab
Annotation tab
Polyline Ending Mode specifies how terminate a polyline.
Measurement Unit
Measurement Unit specifies the measurement unit used for displaying measurement tasks (e.g. Ruler tool in the Annotation mode).
Zoom Filter
ZoomFilter specifies the filter to apply in zoom-in operations for all edit modes.
The fastest way to zoom a picture is to set ZoomFilter to None.
If you need the best quality we suggest: Hermite, Bell, BSpline, Lanczos3, Mitchell, Nearest, Bilinear, Bicubic.
If you need speed we suggest: Triangle, Linear, FastLinear.
