一个将图像转化为256色位图的代码-an image into a 256-color bitmap code

图像的领域处理 ，图像平滑，一阶微分边沿监测，二阶微分边沿监测。-The field of image processing, image smoothing, the first-order differential edge monitoring, monitoring of second-order differential edge.

本程序实现八种图形的绘图功能，分别是直线，圆弧，贝赛尔曲线，矩形，圆角矩形，椭圆和多边形。绘图步骤如下： 直线：点鼠标左键确定起始点，移动鼠标点左键确定终点。 圆弧：用鼠标左键依次点四点确定圆弧。 贝赛尔曲线：用鼠标左键依次点四点确定贝赛尔曲线。 矩形：点左键确定起始点，拖动鼠标再点左键确定对角点。 圆角矩形：点左键确定起始点，拖动鼠标再点左键确定对角点。 椭圆：点左键确定起始点，拖动鼠标再点左键确定对角点，便作出了与该矩形相切的椭圆。 多边形：点鼠标左键确定起始点，然后依次点各点（所有点的总数为所要做多边形的边数，不超过20边），最后用中键确定，自动封闭图形。-the program eight graphical mapping function is linear, arc, Bessel curve, rectangle, rounded rectangle, oval and polygons. Mapping the following steps : Linear : click the mouse button to determine the threshold, mobile click of the mouse button to determine the end. Arc : the left mouse button followed by 4:00 set point arc. Bessel curve : the left mouse button followed by point 4:00 determine Bessel curve. Rectangular : Left to determine the threshold point, then drag the mouse to point to determine Left Corner. Rounded Rectangle : Left to determine the threshold point, then drag the mouse to point to determine Left Corner. Oval : Left to determine the threshold point, drag the mouse butto
