Cannot write image to cRIO?

We took the FRC 2013 Vision Example and uncommented the proper lines to write a threshold image to the cRIO. However, I am not seeing this image anywhere.

Here is some relevant code. All of the changes are in here; everything else is unmodified from the template.

Code:

//while (IsAutonomous() && IsEnabled()) {

            /**

             * Do the image capture with the camera and apply the algorithm described above. This

             * sample will either get images from the camera or from an image file stored in the top

             * level directory in the flash memory on the cRIO. The file name in this case is "testImage.jpg"

             */

                        ColorImage *image;

                        //image = new RGBImage("/testImage.jpg");                // get the sample image from the cRIO flash



                        camera.GetImage(image);                                //To get the images from the camera comment the line above and uncomment this one

                        BinaryImage *thresholdImage = image->ThresholdHSV(threshold);        // get just the green target pixels

                        thresholdImage->Write("/testImage.jpg");

                        BinaryImage *convexHullImage = thresholdImage->ConvexHull(false);  // fill in partial and full rectangles

                        //convexHullImage->Write("/ConvexHull.bmp");

                        BinaryImage *filteredImage = convexHullImage->ParticleFilter(criteria, 1);        //Remove small particles

                        //filteredImage->Write("Filtered.bmp");



                        vector<ParticleAnalysisReport> *reports = filteredImage->GetOrderedParticleAnalysisReports();  //get a particle analysis report for each particle

                        scores = new Scores[reports->size()];

Anybody have an idea why an image isn't being written to the cRIO?

It looks to me like the entire while loop is commented out.

It's commented out because we only want it to write an image once.

Re: Cannot write image to cRIO?

Change the .jpg and .bmp extensions to .png, I had the problem you had and this worked for me.
Also, you should uncomment these lines so you can see all the images proccessed:

Code:

//convexHullImage->Write("/ConvexHull.bmp");

//filteredImage->Write("Filtered.bmp");
