cutLoadPGMf problem

Accelerated Computing CUDA CUDA Programming and Performance

Hello:

I am new to CUDA and I ran into a problem with cutLoadPGMf.

My PGM image size is 2736x3648 pixels. I did a simple program:

float* dataf = (float*)malloc(2736*3648*sizeof(float));
unsigned int width, height;

cutLoadPGMf("IMG_0011.pgm", &dataf, &width, &height);

printf("Loaded %d x %d pixels\n", width, height);

And the printf told me that the width is 86 and the height is 3. And I cannot see why?

Can anybody give me a hint?
