图形学课程设计报告--饼状图,制作此图，首先得明白扇形区域的画法的算法，利用for循环将扇形弧终点坐标赋值给弧开始坐标一块一块平凑成饼状图，而不能画一个圆分割，因为无法填充图案，是因为不是完整图案。所以返工重画了一次。还了解了TextOutA（）和pie方法。以上就是本次从这次实验得到的心得体会。本人还不停的调试了饼状图上比例的位置，直至最好看为止。-Graphics Design Report- pie chart, making this map, first of all have to understand the fan-shaped region, drawing algorithm, using fan-shaped arc for circulation to coordinate assigned to the arc end point coordinates of a starting level make up a pie chart, but not draw a circle divided, because they can not fill pattern, is because they are not complete patterns. So rework redraw once. Also understand TextOutA () and the pie method. Those are the times from this experiment with the work experience. I also keep debugging the pie chart on the percentage of positions until the best-looking date.
