Summary

Type definition of a function that detects the size and skew angle. Operates on glyph marks in a small region of an image.

Parameters

context		Specify the context
image		The Glyph image
rect		The region of interest whithin the image
minAngle		The minimum angle in [-pi, pi] to detect
maxAngle		The maximum angle in [-pi, pi] to detect
info		Pointer to an array, each entry of which may be used to hold a possible configuration info of the glyph image on output.
lenInfo		On input, *lenInfo indicates the length of array info[]; On output, *lenInfo indicates the number of possible configurations detected. The implementation of this interface is responsible to make sure that the output value of *lenInfo is no greater than the input value of *lenInfo.
privData		Private of the glyphtone mark.

Output Parameters

info		See above explanation
lenInfo		See ahove explanation
