Nonogram Deluxe

Nonograms, also known as Paint by Numbers, Picross, Griddlers, Pic-a-Pix, kenken, kakuro, pictogram, numbrix, shikaku, nurikabe and various other names, are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden picture. In this puzzle type, the numbers are a form of discrete tomography that measures how many unbroken lines of filled-in squares there are in any given row or column. For example, a clue of "4 8 3" would mean there are sets of four, eight, and three filled squares, in that order, with at least one blank square between successive sets.
