Abstract
An apparatus may include a transparent platen, a command interface, a scanner unit, a controller and an indicator. The command interface is to receive externally originating instructions including a selected scaling value, other than 100%, for a scanning operation of a document resting against the transparent platen, wherein contents of the document to be scanned are proportionally magnified or shrunk based on the selected scaling value The controller controls a scanner unit to capture a portion of the transparent platen, the portion having borders automatically determined and proportionally changed by the controller based upon the selected scaling value. The indicator provides a visible indication of the portion.
Claims20
An apparatus comprising:
- a transparent platen;
- a command interface configured to receive externally originating instructions including a selected scaling value, other than 100%, for a scanning operation of a document resting against the transparent platen, wherein contents of the document to be scanned are proportionally magnified or shrunk based on the selected scaling value and wherein the selected scaling value impacts an area of the transparent platen that will be captured during the scanning operation;
- a scanner unit comprising a carriage movable across the platen;
- a controller to control the scanner unit to capture a portion of the transparent platen, the portion having borders automatically determined and proportionally changed by the controller based upon the selected scaling value;
- and
- an indicator providing a visible indication of the portion,
- wherein movement of the carriage repositions the visible indication, wherein the visible indication of the scan area provided by the indicator on the carriage indicates a width of the portion.
A method comprising:
- determining what portion of a transparent platen will be captured during a scanning operation based upon a selected scaling value to proportionally magnify or shrink captured contents of a document during a scanning operation, wherein the selected scaling value impacts an area of the transparent platen that will be captured during the scanning operation;
- and
- moving a scanner carriage to a position to indicate at least one dimension of the determined portion prior to receipt of a scan command initiating the scanning operation.
