Spritemapper is an application that merges multiple images into one and generates CSS positioning for the corresponding slices.
Spritemapper is a tool for easing this process by merging multiple images into a single one and creating the CSS positioning rules for each slice.

The tool is a simple command-line tool that performs the job via a Python package including its own PNG and CSS parser (without any 3rd-party dependencies).
