Tileset Splitter is a program by Xgoff that is designed to break apart images into rectangles; these rectangles are then saved as separate files.
The first and currently only released version, it supports basic features such as being able to set tiles' heights and widths, their X and Y spacing, and the X and Y offset of the entire array. Unfortunately, version 1.0 only works well with tilesets or sprite sheets that are entirely consistent in tile size, spacing, and offset. A bug in the grid drawing makes it nearly useless when scrolling, but with a conforming tileset, scrolling really isn't needed. Version 1.0 only supports BMP export and tile sizes up to 128 x 128.
- Adjustable tile size, spacing, and offset
- Grid that allows visibility toggled
- XOR-able grid, with the ability to mask areas that will not be ripped
Currently in development. It will include the basic features on Version 1.0, and add even more.
- Same features as Version 1.0, max tile size increased to 512 x 512
- "Custom Grid" mode: allows the user to draw rectangles of any size in any location
- "Array" feature for Custom Grid: emulates the Basic Grid mode, allows user to place arrays of rectangles (same limitations as Basic Grid mode) in addition to their custom rectangles
- Magnifier: useful for exact placement of rectangles
- PNG export with optional alpha channel
