在picturebox上移动函数的绘图 [英] Move plotting of functions on picturebox

问题描述

我有功能绘制在picturebox上，我可以放大它，当图形超出picturebox我想要用scroolbars移动它或鼠标移动来观看它的部分隐藏。每次我点击滚动条，我清除图片框然后我添加到功能的坐标滚动的值，并再次重绘它。但是我不知道为什么picturebox不干净并且像图形拖动一样出现。我该如何避免这种情况。虽然我不得不等待一段时间，但工作在VB6但不在NET中。我想要一些类似autocad的东西，移动画画和inmediatly我得到画面毫不拖延。



提前感谢

我尝试过：



代码到目前为止还没有成功，需要帮助

i have function plotted on picturebox, i can zoom it, when graphic are out of picturebox i want with scroolbars move it or mouse movement to watch part hide of it. everytime i click to scrollbar, i clear picturebox then i add to coordinates of functions the value of scroll and redraw it again. however i don`t know why picturebox doesn`t clean and show up like the graphic dragging. how do i avoid that. worked en VB6 but not in NET although i have to wait a while. i want something like autocad, to move draw and inmediatly i get draw without delay.

thanks in advance

推荐答案

这是因为为此目的使用 PictureBox 是疯了。当然，可以使用 PictureBox 来完成所有操作，但它完全没有意义。您只需完成双重工作，不仅在运行时使用额外的资源，而且还浪费您的开发时间。 PictureBox 不是图片，它是一个完全冗余的控件，专门用于简化最简单的杂务，在屏幕上显示静态图像。

This is because using PictureBox for such purposes is insane. Of course, it would be possible to do it all with a PictureBox, but it makes no sense at all. You simply do double work, not only using extra resources during runtime, but also wasting your development time. PictureBox is not a picture, it's a control, totally redundant one, created exclusively to simplify the simplest chores, showing static image on your screen.
