This is an image editor that can be integrated in a web application.
The drawing tools and GUI can be customized for specific needs,
for example:

  Sketch editor   Medicine drawing
  Photo annotation   Weather Map editor
  Ecard editor   Diagram editor

The developer can use cliparts, define drawing colors, custom
strokes, fill patterns, decide which tools are available and
arrange them in preferable order on the page.

The editor allows drawing over background image, supports
translucent colors, cliparts in PNG, GIF, JPEG, SVG formats.

The image can be loaded in PNG, GIF, JPEG formats and saved
on the server in PNG or JPEG formats. The image can be saved
in its original size or scaled (e.g. to produce a thumbnail).

The editor is compatible with all major browsers on desktop
and mobile platforms. It's implemented in HTML5 and JavaScript
(no plugins, no 3rd party libraries).
