Sprite Generator makes it easier for web developers to create sprite images. It's developed in C#. This application creates a nearly optimal insertions of images into a CSS Sprite. The major algorithms used rest on O-tree based rectangle packing.

This application was originally developed by csigusz and it's code was located at his CodePlex repository. The project was abandoned, so I decided to forge and add some extra stuff.

The application contains a list of self-descriptive configuration. You will be able to configure the input and output path, the file name and the layout for the generated CSS file.

Paths:

• Images directory: Only JPG/JPEG, PNG, GIF image formats are allowed.
• Output path: The directory where the generated CSS file will be stored.
• File name: The generated file name.

Layout:

• Automatic: image layout based on the algorithms mentioned above.
• Horizontal/ Vertical: simple horizontal/vertical image layout only for images with the same height/width.
• Rectangular: rectangular layout for images with the same height and the same width.

Distances:

• Distance between images: distance in pixels. This option does not set margin width for the sprite.
• Margin width: The margin between each image in pixels.

CSS

• Prefix: a prefix for all the CSS classes.
