The first example shows how to get the last key that was pressed within the active image window in CVI. In addition, any modifiers that were pressed (ctrl, alt, shift, and caps lock) will also be shown. Multiple modifiers can be used at the same time, with the exception of ctrl+alt. This program requires an IMAQ board and acquires an image from "img0" by default.
NOTE: All modifiers are applied to the key before it is displayed. The ctrl modifier only works with letter keys and makes them non-displayable ASCII characters.
The second example returns the pixel value at the location where a user clicked.
The third example resizes the image to match the window size as the user resizes the window.
The fourth example shows how to use the CWIMAQViewer with ROIs in Visual Basic.
The fifth example allows the user to draw a ROI and zooms into that region.
