• 如何履行 Draw职能?
原标题:How to implement a DrawLine function ?

问题:除了在投入点上打上圈子之外,是否还能更好地执行一条参照屏幕的功能?

详细情况:我正试图写出一个基本上可以划线的职能。 但是,这条线不会是固定的有色线。 这条线路将使用户能够复制从一个图像到另一个线的图象。 它像照片上的“血压”或“灯”。 我的第一项想法只是从各个角度来看待,并从中汲取。 这些工作虽然不顺利,但有一些弊端。 第一个问题是,如果用户 too得太快,就没有工作。 我认为,如果能够在两点之间填满ts子,然后划定那种工作线,那么这个问题就会得到解决,但此时此刻,工作速度非常缓慢。 另外一个问题是,它从来不顺利。
