Prototype

 

floatAngle:=ImgEvaluateSkew(intImageHandle, intRange, floatResolution, intStep)

 

Description

 

Evaluates skew angle for the image.

 

Parameters

 

intImageHandle: integer value corresponding to the image handle.

 

intRange: integer value that specifies the range of deskewing (between -SpecifiedValue and +SpecifiedValue);

 

floatResolution: resolution used in deskew procedure.

 

intStep: rows step in the loop that reads and analyzes rows of the image (0: Automatic; 1:All the rows)

 

Returned value

 

Float value with calculated skew angle.

 

Notes

 

To evaluate and correct skew use ImgDeskew.

 

Example

 

// Find skew angle

angle:=ImgEvaluateSkew(_CurrentImage, 5, 0.1, 0);

 

// Log a message 

ApplicationLog('Skew angle is: '+ FloatToStr(angle) +'°.');
