## 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** &amp; **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** &amp; **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/
