If either the image isn't divisible by width or by height, error message s are displayed the program exits. These two variables will be either true or false depending on whether the image is exactly divisble by the tile size. ImageDatas have methods getWidth and getHeight. To quit the program at this position in love. Here it is being created using the filename of an image file. ImageDatas can't be drawn to the screen directly, but they can be converted to Images using love. It can be used to get and set pixel values, and save images to files, among other things. Note that this won't actually change the image's colour, it will only affect the image detection. In effect, this can make the pixels more similar. Every pixel value is divided by this variable, with any decimal places removed. The maximum number of tiles in each row of the output image is the next argument, or 8 by default. The width and height of each tile square is the next argument, otherwise the common tile size of 16 is used by default. The disjunction operator or returns its first argument if this value is not nil or falseotherwise it returns its second argument. If there are no command-line arguments, then input. The first command-line argument not including the name of the directory is the name of the input file.

Sprite Sheet Maker can take command-line arguments so you might want to run it from the command-line. This can be useful for input images which have JPEG artifacts. Sprite Sheet Maker takes an image made up of tiles, like this It can also recognise tiles which have similar colours, but are not quite the same. Tile-based video games are made up of a grid of tiles, where scenes are constructed from combining the images of a sprite sheet. Sprite Sheet Maker is by josefnpat and can be found here.
