slide_imageslide_imageslide_imageSlideImageSlideImage (Operator)

Name

slide_imageslide_imageslide_imageSlideImageSlideImage — Interactive output from two window buffers.

Signature

slide_image( : : WindowHandleSource1, WindowHandleSource2, WindowHandle : )

Herror slide_image(const Hlong WindowHandleSource1, const Hlong WindowHandleSource2, const Hlong WindowHandle)

Herror slide_image(const HTuple& WindowHandleSource1, const HTuple& WindowHandleSource2, const HTuple& WindowHandle)

void HWindow.SlideImage(HWindow windowHandleSource2, HWindow windowHandle)

Description

slide_imageslide_imageslide_imageSlideImageSlideImage 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_imageslide_imageSlideImageSlideImage.

A useful application of the operator slide_imageslide_imageslide_imageSlideImageSlideImage might be the visualisation of the effect of a filtering operation for an image. The output is directed to the current set window (WindowHandleWindowHandleWindowHandleWindowHandlewindowHandle).

Attention

The three windows must have the same size and have to reside on the same computer.

disp_image(Dir,Buffer2) ;
open_window(0,0,-1,-1,"root","visible","",&WindowHandle) ;
slide_image(Buffer1,Buffer2,WindowHandle) ;

Example (HDevelop)

open_window(0,0,-1,-1,'root','buffer','',Buffer2)
disp_image(Dir,Bufer2)
open_window(0,0,-1,-1,'root','visible','',WindowHandle)
slide_image(Buffer1,Buffer2,WindowHandle)

Example (HDevelop)

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,Bufer2)
open_window(0,0,-1,-1,'root','visible','',WindowHandle)
slide_image(Buffer1,Buffer2,WindowHandle)

Result

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