Buffer Information
The background of the DMA Output Display pane informs you in case you don't use buffer space you have allocated:
- Blue background has no meaning.
- Red background: Invalid Data. There is buffer allocated, but not used because the frame of the acquired image is smaller than the buffer allocated via applet parameters ROI width and Hight.
Make sure the ROI dimensions in your applet (DMA) configuration do not exceed the dimensions of the images acquired by the camera.
If ROI is bigger, invalid data are acquired and - in microDisplay X - displayed in red.
