brainmort Posted February 12, 2011 Report Share Posted February 12, 2011 Hi, I'm trying to create a custom image-viewing indicator using XControls. The problem is the data change event is never triggered (the images come from a camera). As I understand, this happens because the input for my indicator is a pointer to an image, i.e. I32, and as the data changes, the pointer value stays constant. On the other hand, I've tried to use standard "Picture" data type as an input, and the data change event got triggered as the picture changed. But in the Picture data type, a raster image is stored by a pointer too. So, why does the data change event happen in one case and is never triggered in another? Thanks in advance Quote Link to comment
Ton Plomp Posted February 12, 2011 Report Share Posted February 12, 2011 Isn't there a special IMAQ-image change event? You could register for that event. Ton Quote Link to comment
brainmort Posted February 12, 2011 Author Report Share Posted February 12, 2011 Well, the thing is I'm not using IMAQ and I'm not supposed to. I use OpenCV to handle the camera. Quote Link to comment
