## Introduction
**Aseprite** is an open source program to create animated
sprites. Sprites are little images that can be used in your website or
in a video game. You can draw characters with movement, intros,
textures, patterns, backgrounds, logos, color palettes, isometric
levels, etc.
What makes Aseprite different? It focuses on pixel editing, to do
pixel-art. Indeed, it isn't a photo retouching tool or a vector
graphics editor. Mainly it is a tool to create tiny animations
pixel-by-pixel.
## Features
The main features of Aseprite are:
* Sprites are composed by **layers** & **frames**.
* Supported color modes: **RGBA**, **Indexed** (palettes up to 256
colors), and Grayscale.
* Supported image formats (load/save): **PNG**, **GIF**, JPG, FLC,
FLI, BMP, PCX, TGA, and ASE (special format).
* Load and save animations in a **sequence of bitmaps**
(e.g. frame1.png, frame2.png, etc.).
* **Tiled** drawing mode, useful to draw **patterns** and textures.
* **Undo/Redo** for every operation.
* **Multiple editors** support. You can split an editor horizontally
or vertically multiple times to edit and view the same sprite with
different zooms, or different sprites.
* Import/Export **Sprite Sheets**.
* Pixel art specific tools like filled **Contour** & **Polygon**.
* **Onion skinning**
## Configuration files
In Windows XP/Vista/7 the main configuration file is `aseprite.ini`
which is saved in the same folder of `aseprite.exe` executable file
(in this way Aseprite is a portable application, i.e. you can
transport a copy of the program in your USB drive).
The following is a list of all configuration files that you could
modify (it is not recommended to do so, but is useful if you want to
super-customize Aseprite):
aseprite.ini Program configuration
data/gui.xml Menus, shortcuts, and tools
data/convmatr.def Convolutions matrices
data/skins/*.* Aseprite skins
data/widgets/*.xml XML files with dialogs
In GNU/Linux, the configuration file is ~/.asepriterc, and the data/
files are searched in these locations (in priority order):
$HOME/.aseprite/
../share/aseprite/
./data/
