/**
* <p>Draws the found matches of keypoints from two images.</p>
*
* <p>This function draws matches of keypoints from two images in the output image.
* Match is a line connecting two keypoints (circles). The structure
* <code>DrawMatchesFlags</code> is defined as follows: struct DrawMatchesFlags
* <code></p>
*
* <p>// C++ code:</p>
*
*
* <p>enum</p>
*
*
* <p>DEFAULT = 0, // Output image matrix will be created (Mat.create),</p>
*
* <p>// i.e. existing memory of output image may be reused.</p>
*
* <p>// Two source images, matches, and single keypoints</p>
*
* <p>// will be drawn.</p>
*
* <p>// For each keypoint, only the center point will be</p>
*
* <p>// drawn (without a circle around the keypoint with the</p>
*
* <p>// keypoint size and orientation).</p>
*
* <p>DRAW_OVER_OUTIMG = 1, // Output image matrix will not be</p>
*
* <p>// created (using Mat.create). Matches will be drawn</p>
*
* <p>// on existing content of output image.</p>

*
* <p>DRAW_RICH_KEYPOINTS = 4 // For each keypoint, the circle around</p>

* @param img1 First source image.
* @param keypoints1 Keypoints from the first source image.
* @param img2 Second source image.
* @param keypoints2 Keypoints from the second source image.
* @param matches1to2 Matches from the first image to the second one, which
* means that <code>keypoints1[i]</code> has a corresponding point in
* <code>keypoints2[matches[i]]</code>.
* @param outImg Output image. Its content depends on the <code>flags</code>
* value defining what is drawn in the output image. See possible
* <code>flags</code> bit values below.
* @param matchColor Color of matches (lines and connected keypoints). If
* <code>matchColor==Scalar.all(-1)</code>, the color is generated randomly.
* @param singlePointColor Color of single keypoints (circles), which means that
* keypoints do not have the matches. If <code>singlePointColor==Scalar.all(-1)</code>,
* the color is generated randomly.
* @param matchesMask Mask determining which matches are drawn. If the mask is
* empty, all matches are drawn.
* @param flags Flags setting drawing features. Possible <code>flags</code> bit
* values are defined by <code>DrawMatchesFlags</code>.
