在PictureBox的16位点击鼠标限制 [英] 16 bit mouse click limit on picturebox

问题描述

这是一个C＃问题。
我有一个表格。在窗体上我有一个面板。在面板上我有一个非常大的滚动位图（Y >> 32768）一个图片框。当图片框Y大于32767据我所知，鼠标点击被限制为16位的图片框单击事件不火。

This is a C# question. I have a form. On the form I have a panel. On the panel I have a picture box with a very large scrollable bitmap (Y >> 32768). The picture box click event does not fire when the picture box Y is greater than 32767. I understand that mouse clicks are limited to 16 bits.

有没有办法让底层面板的鼠标点击，所以我可以从滚动条当前位置计算Y和面板的y坐标？

Is there way to get a mouse click of the underlying panel so I can compute Y from the scroll bar positon and the y coordinate of the panel?

推荐答案

你有没有尝试新的方法，如降尺度位图以32K大小（或更少）之前，而不是显示它在全尺寸显示呢？您可以通过降尺度系数乘以其价值得到真正的X / Y位置。

Did you try another approach, such as "downscale" the bitmap to 32k size (or less) before to display it rather to display it in full size ? You could get the real X / Y position by multiply its value by the downscaling factor.

这不知道是否有过32k的障碍，但是，即使你可以，我想这在UI会很慢，根据您的图片的大小，一个简单的方法...

It don't know if there is an easy way to cross the 32k barrier but even if you could, I guess that the UI will be very slow according the size of your picture...
