Cannot save images to file

[sabrinazuraimi]

I've built InfiniTAM with FFMPEG support on and I wanted to save the images captured while running the app by using the button 's'. However, the output image was not saved.

From FileUtils.cpp, this is the code that gets run when pressing the 's' button. It looks like it need to read pnm files but since I already have FFMPEG support on, that should not be a problem right??

void SaveImageToFile(const ORUtils::Image<short>* image, const char* fileName)
{
    short *data = (short*)malloc(sizeof(short) * image->dataSize);
    const short *dataSource = image->GetData(MEMORYDEVICE_CPU);
    for (size_t i = 0; i < image->dataSize; i++) data[i] = (dataSource[i] << 8) | ((dataSource[i] >> 8) & 255);

    FILE *f = fopen(fileName, "wb");
    if (!pnm_writeheader(f, image->noDims.x, image->noDims.y, MONO_16u)) {
        fclose(f); return;
    }
    pnm_writedata(f, image->noDims.x, image->noDims.y, MONO_16u, data);
    fclose(f);

    delete data;
}

This is the output I get when I run the app btw

In InfiniTAM.cpp, the UI engine is initialised like this:

UIEngine::Instance()->Initialise(argc, argv, imageSource, imuSource, mainEngine, "./Files/Out", internalSettings->deviceType);

This means that the output files will be saved to ./Files/Out. If that directory doesn't exist, they won't be saved - try creating the directory and see if that works.

When I created the folder, it works!
