Golang cvCreateMat Examples

Example #1

File: image.go Project: mottalli/go-cv

/******* Rotate *******/
func (img *Image) RotateTo(dest *Image, angle float64) {
	dest.InitializeAs(img)

	center := C.CvPoint2D32f{C.float(img.Size().Width / 2), C.float(img.Size().Height / 2)}
	var rot *C.CvMat = C.cvCreateMat(2, 3, C.CV_32F)
	defer C.cvReleaseMat(&rot)
	C.cv2DRotationMatrix(center, C.double(angle), C.double(1.0), rot)

	C.cvWarpAffine(img.ptr, dest.ptr, rot, C.CV_INTER_LINEAR+C.CV_WARP_FILL_OUTLIERS, C.cvScalarAll(C.double(0.0)))
}

Example #2

File: cxcore.go Project: tonycoming/go-opencv-1

/* Allocates and initializes CvMat header and allocates data */
func CreateMat(rows, cols, type_ int) *Mat {
	mat := C.cvCreateMat(
		C.int(rows), C.int(cols), C.int(type_),
	)
	return (*Mat)(mat)
}
