请注意，由于全局座标空间的原点位于工作区的左上角，因此画面座标和全局座标是相同的。
Note that because the origin of the world coordinate space is at the upper-left corner of the client area, the page coordinates are the same as the world coordinates.
工作区座标的原点位于控制项或表单的工作区的左上角。
The origin for client coordinates is the upper-left corner of the client area of the control or form.
原点相对于屏幕的位置因指定的是屏幕坐标还是工作区坐标而异。
The location of the origin, relative to the screen, will vary depending on whether you are specifying screen or client coordinates.
例如，您希望原点位于距离工作区左边缘 100像素和距离工作区顶端50 像素的位置。
Say, for example, that you want the origin to be 100 pixels from the left edge of the client area and 50 pixels from the top of the client area.
请注意，页面坐标空间的原点在工作区的左上角，情况将总是如此。
Note that the page coordinate space has its origin at the upper-left corner of the client area; this will always be the case.
请注意，页面坐标空间的原点在工作区的左上角，情况将总是如此。
