Instead of adding and removing individual sprites TexturePacker allows you to simply add a complete asset folder. Every image that is found inside it will be added to the sprite sheet.

TexturePacker preserves your folder structure in the sprite names inside the data file allowing you to easily group your sprites.

TexturePacker detects all changes and automatically reads the new sprite data when re-entering the application or publishing from commandline.

With the powerful commandline interface you can simply update all sprite sheets at once.

Trimming removes transparent pixels from the border of your sprites. This has two advantages:

• Reduces texture size
• Faster rendering

Trimming preserves the sprite's size - the framework needs special support to restore the transparent parts when rendering the sprite.

Cropping in contrast removes the transparent parts - making the sprite appear as if it never had any transparent border.

Alias creation

If two images are identical after trimming only one image is placed in the sprite sheet. The duplicates will just be added to the description file allowing you to access it with both names. This is perfect when using animations: You simply don't have to care about equal phases.

Import

You can import the following file formats directly into TexturePacker

• SWF - Flash animations
• PSD - Photoshop image
• PNG - Portable network graphics
• TGA - Targa Image File
• JPG - Joint Photographic Experts Group
• TIFF - Tagged image file format
• BMP - Bitmap

Basic

This layout algorithm is best for tilemaps and simple animations without the need of additional data file. Sprites are simply placed in a row until the row is full. Then the next row starts. You may sort the sprites by name, width, height or area. This algorithm is FREE and can be used for all projects.
