Displaying Images 75 FIGURE 4.19 Simple image browser example. FIGURE 4.20 Simple image browser example — wiring diagram. As the image browser is a ßoating IMAQ image window, you can embed it as a child into a parent VI, as discussed previously (Figure 4.21). Adding this code embeds the image browser into the parent VI’s front panel (Figure 4.22). One useful example of image browsers is to allow the user to select a thumbnail, and then display (and perhaps process) the full image on the front panel of a VI. This is achieved by embedding both the image browser and preview image into the parent VI, and using the selected browser thumbnail to dictate which image is loaded into the preview image (Figure 4.23). As not to continually load images into the preview image, even when the user has not selected a different image, IMAQ WindLastEvent is used to monitor if the user has clicked within the image browser (Figure 4.24)
