Description: 本文主要介绍下opencv中自带的一个随机数发生器的类RNG，这里我用这个类来画一些图形，和基础学习笔记之opencv(13)：基本绘图 一文中类似，只是 这里画出来图像的坐标，大小，颜色，角度等所有信息都是随机的，且是用RNG这个类产生的。参考文献为opencv自带tutiol及其代码。
开发环境：opencv2.4.2+Qt4.8.2+ubuntu12.04+QtCreator2.5
实验功能：
1. 该实验可以画6中几何图形和1个文本显示，每种都是画80个，每画完一个延时100ms。
2. 打开软件后，默认画的图为直线。可以在软件的左下角Drawing Type下拉列表中选择不同的几何绘画图形及文字，这6种几何图形分别为画直线，画矩形，画椭圆弧线，画多边形，画圆，画填充多边形。文本显示为显示“OpenCv Forever!”，选择完后在窗口中会自动显示其随机绘图过程，
3. 单击Close按钮，退出软件。-This article introduces a random number generator that comes in under opencv class RNG, I use this class to draw some graphics, and study notes based on opencv (13): Basic Drawing a text similar to just draw out the image coordinates, size, color, angle, and all information is random, and this class of RNG.

Description: 制作印章实例,用到Graphics来根据设定的公司名称和用章信息绘制出一个圆章
来制作公司的公章，制作印章来说，主要是如何让字均匀的
显示在弧线段上，那么一般的印章要么以圆或者椭圆为底图，不过这两者的算法大致相同，
为了方便说明，
如下就用相对简单的圆来举例说明，
如果需要做椭圆的话，
可以在我的基础
上进行扩展，因为核心算法是一样的，相对于圆来说，椭圆求弧长以及各个字符的位置，这
两点相对麻烦些，但是这两者都可找到相应的数学公式。-Production seal instance, use Graphics to set the company name in accordance with chapter information and draw a circle chapter to make the company' s official seal, making the seal, the main character is how to make uniform is displayed on the arc segment, then the general The seal is either in a circular or elliptical base map, but this method is substantially the same both for convenience of explanation, the following will be a circle with a relatively simple example, if the ellipse needs to be done, it can be extended on the basis of the I, Because the core is the same algorithm with respect to a circle, the position of the arc length of the ellipse and the individual characters required, which is relatively trouble some points, but the two can be found corresponding mathematical formula.
