Summary

Detect the size and skew angle of glyph marks. Operates in a small region of an image.
The caller is responsible to allocate array info[], and set the value of *lenInfo to the length of the array. On return, detected configurations are stored in info[], up to the length of the array. *lenInfo is set to the number of detected configurations. If possible,DgFindGlyphGeom() shall store the results in info[] in decreasing probability, i.e. the most probable configuration is stored in info[0].
The caller of this function may decide how many configurations it is willing to try by limiting the length of array info[]

Parameters

context		Specify context
image		Specify which image to analyze
rect		Specify a region of the image, or NULL for the entire image
minAngle		Specify the smallest angle, between -PI/4 and PI/4 in radians, to consider
maxAngle		Specify the largest angle, between -PI/4 and PI/4 in radians, to consider.
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.

Output Parameters

info		See above explanation
lenInfo		See ahove explanation

Return Value

DG_OK If successful
