Go OpenCV (GOlang openCV)

Wrap the core types in OpenCV.

Supporting Types and Examples

OpenCV C++	Go OpenCV	Constructor
cv::Point2i	GcvPoint2i	NewGcvPoint2i(x, y int)
cv::Point2f	GcvPoint2f32_	NewGcvPoint2f32(x, y float64)
cv::Point2d	GcvPoint2f64_	NewGcvPoint2f64(x, y float64)
cv::Point3i	GcvPoint3i	NewGcvPoint3i(x, y, z int)
cv::Point3f	GcvPoint3f32_	NewGcvPoint3f32(x, y, z float64)
cv::Point3d	GcvPoint3f64_	NewGcvPoint3f64(x, y, z float64)
cv::Size2i	GcvSize2i	NewGcvSize2i(x, y int)
cv::Size2f	GcvSize2f32_	NewGcvSize2f64(x, y float64)
cv::Size2d	GcvSize2f64_	NewGcvSize2f64(x, y float64)

Note for Renamed Types

Some of the types are renamed to *_. The reason is that we'd like to wrap a better interface for them.
For example, the original NewGcvPoint2f32 takes strictly two float32, and we are not able to pass float64 or int, which doesn't make too much sense.
After wrapping an extra level, we are now able to pass int, float32, and float64 to these methods.
Also note that renaming doesn't affect any usage, except you are manipulating the types yourself.
