Parameters

ImageID

GdPicture image identifier.

MaxAngleOfResearch

Maximum angle of research. IE: set 10 to perform a skew research about ±10 degrees. A value lower tha 15 is suggested.

BackColor

Color to use to fill background. A suitable color value can be obtained by using the ARGB() method.

AngleStep

Determines the smallest angle of skew to detect. 0.25 is suggested. Higher value results in faster detection and vice-versa.

Optimistic

Determines if the engine must be optimistic in the skew detection. For example, set true when you know the image has a skew and false otherwise. Default value is false.

Return Value

When minor skewing of images does not affect the subsequent processes, sometimes it is perferred not to deskew the image, could be for quality or timesaving. This method offers the input of a cutt off value, where slight skewing is allowed.

Be aware: If the skew angle is larger than the cutt off value, the returned value will be rounded to the nearest multiple of (AngleStep)

This method requires the Image Documents component to run.
