slide_imageT_slide_imageSlideImageSlideImageslide_image (算子)

名称

slide_imageT_slide_imageSlideImageSlideImageslide_image — 来自两个窗口缓冲区的交互式输出。

警告

The operator slide_imageslide_imageSlideImageSlideImageSlideImageslide_image does not work with HDevelop graphics windows. It is only provided for reasons of backward compatibility.

签名

slide_image( : : WindowHandleSource1, WindowHandleSource2, WindowHandle : )

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 the operator slide_imageslide_imageSlideImageSlideImageSlideImageslide_image.

A useful application of the operator 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.

示例（HDevelop）

read_image (Image, 'fabrik')
sobel_dir (Image, EdgeAmplitude, EdgeDirection, 'sum_abs', 3)
dev_open_window (0, 0, 512, 512, 'black', WindowHandle1)
dev_display (EdgeAmplitude)
dev_open_window (0, 0, 512, 512, 'black', WindowHandle2)
dev_display (EdgeDirection)
dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
slide_image (WindowHandle1, WindowHandle2, WindowHandle)

示例（C）

read_image(&Image,"fabrik");
sobel_amp(Image,&Amp,"sum_abs",3);
open_window(0,0,-1,-1,"root","buffer","",&Buffer1);
disp_image(Amp,Buffer1);
sobel_dir(Image,&Amp,&Dir,"sum_abs",3);
open_window(0,0,-1,-1,"root","buffer","",&Buffer2);
disp_image(Dir,Buffer2);
open_window(0,0,-1,-1,"root","visible","",&WindowHandle);
slide_image(Buffer1,Buffer2,WindowHandle);

示例（HDevelop）

read_image (Image, 'fabrik')

dev_display (EdgeAmplitude)
dev_open_window (0, 0, 512, 512, 'black', WindowHandle2)
dev_display (EdgeDirection)
dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
slide_image (WindowHandle1, WindowHandle2, WindowHandle)

示例（HDevelop）

read_image (Image, 'fabrik')
sobel_dir (Image, EdgeAmplitude, EdgeDirection, 'sum_abs', 3)
dev_open_window (0, 0, 512, 512, 'black', WindowHandle1)
dev_display (EdgeAmplitude)
dev_open_window (0, 0, 512, 512, 'black', WindowHandle2)
dev_display (EdgeDirection)
dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
slide_image (WindowHandle1, WindowHandle2, WindowHandle)

结果

If the both windows exist and one of these windows is valid slide_imageslide_imageSlideImageSlideImageSlideImageslide_image 返回 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
