rectangle function

基本解释

Notice how in this function a rectangle of chunkSize by chunkSize pixels is copied from the appropriate frame to the drawable surface.
注意：在此函数中，长为 chunkSize、宽为 chunkSize 的像素矩形是如何从恰当的帧复制到绘图表面的。
If the destination rectangle is larger than the source rectangle, this function stretches the rows and columns of color data to fit the destination rectangle.
如果目标矩形大于源矩形，此函数将拉伸的行和列以适合目标矩形的颜色数据。
The problem was discussed that a minimum containment rectangle is transformed to function optimization and meanwhile the optimized solution was found with genetic algorithm.
建立了求任意多边形包容矩形的数学模型，将求最小包容矩形问题转化为函数优化问题，并用遗传算法求得函数的最优。
