// A byte-array is used for storing the gray-color-values.
// The img has the size 256x256 pixel;
// Each pixel has a gray-color-value from 0-255 (0...black, 255...white).
// Note also that the FIRST dimension (row-index) corresponds
// to the x-Coordinate (!!!) in the image, the second dimension (col-index)
// to the y-coordinate (!!!). The y coordinate goes from up to down!
// Thus, an index of [50, 250] is at the left and bottom of the image.
// (The Write/ReadPGM-Methods internally transpose the matrix.)
// Open Lena, make it black-white (threshold is the value 128), and save it:
