56 CHAPTER 2. GRAPHICAL USER INTERFACE Clicking on a variable will select it. Similar to iconic variables, all program lines that use this variable are then marked with a black rectangle on the left. Double-clicking a control variable opens a window that displays all its values. In most cases this will be a dialog containing a scrolled list. This is helpful if you have variables with a large number of values that you want to inspect. In the case of a frame grabber handle, a dialog Figure 2.37: Variable inspection for frame grabber handles. representing basic frame grabber parameters is opened (see figure 2.37). Here you find the size, name, device, port, and other features of the frame grabber. The toggle button ÇÒÐÒ allows to grab images continuously and to display them in the active graphics window. If an error occurs during grabbing, it is displayed in the status bar of the dialog. At most one of these frame grabber dialogs can be opened at the same time. 2.7 Graphics Window This window displays iconic data. It has the following properties: ¯ The user may open several graphics windows. ¯ The active graphics window is shown by the green dot in the ØÚ button. ¯ Pressing the ÐÖ button clears the graphics window content and the history of the window. ¯ You close a graphics window using the close button of the window frame. Figure 2.38 shows an example for a graphics window. The the origin of the graphics window is the upper left corner with the coordinates (0,0). The x values (column) increase from left to right, the y values increase from top to bottom. Normally, <strong>HDevelop</strong> / 2000-11-16

GRAPHICS WINDOW 57 Figure 2.38: <strong>HDevelop</strong>’s graphics window. the coordinate system of the graphics window corresponds to the the most recently displayed image, which is automatically zoomed so that every pixel of the image is visible. The coordinate system can be changed interactively using the menu Î×ÙÐÞØÓÒ º ËØ ÈÖÑØÖ×ººº º ÓÓÑ (see section 2.3.2.4) or with the operator Ú ×Ø ÔÖØ (see page 38). Every time an image with another size is displayed, the coordinate system will be adapted automatically. Each window has a history that contains all ¯ objects and ¯ display parameters that have been displayed or changed since the most recent ÐÖ or display of an image. This history is used for redrawing the contents of the window. The history is limited to a maximum number of 30 “redraw actions”, where one redraw action contains all objects of one displayed variable. Other output like text or general graphics like ×Ô ÐÒ or ×Ô ÖÐ or iconic data that displayed using HALCON operators like ×Ô Ñ or ×Ô ÖÓÒ are not part of the history, and are not redrawn. Only the object classes image, region, and XLD that are displayed HALCON 6.0
