slide_imageT_slide_imageSlideImageSlideImageslide_image (算子名称)
名称
slide_imageT_slide_imageSlideImageSlideImageslide_image — Interactive output from two window buffers.
警告
该算子 slide_imageslide_imageSlideImageSlideImageSlideImageslide_image does not work with HDevelop graphics windows.
It is only provided for reasons of backward compatibility.

描述
slide_imageslide_imageSlideImageSlideImageSlideImageslide_image divides the window horizontal in two logical
areas dependent of the mouse position. The content of the first indicated
window is copied in the upper area, the content of the second window is copied
in the lower area. If you press the left mouse button you may scroll the
delimitation between the two areas (you may move the mouse outside the
window, too. In doing so the position of the mouse relative to the
window determines the borderline).
Pressing the right mouse button in the window terminates 该算子
slide_imageslide_imageSlideImageSlideImageSlideImageslide_image.
A useful application of 该算子 slide_imageslide_imageSlideImageSlideImageSlideImageslide_image might be the
visualization of the effect of a filtering operation for an image.
The output is directed to the currently set window (WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle).
注意
The three windows must have the same size and have to reside on the
same computer.
运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。

结果
If the both windows exist and one of these windows is valid
slide_imageslide_imageSlideImageSlideImageSlideImageslide_image returns 2 (
H_MSG_TRUE)
.
If necessary an exception is raised.
