Usage

Start oppa using:

$ oppa --help
usage: oppa [-h] [-o] [-z]

optional arguments:
        -h, --help       show this help message and exit
        -o, --opaque     start in opaque mode
        -z, --minimized  start minimized

After starting oppa opens top level transparent window on which one can draw using left mouse button. Apart from drawing following actions (keys) are available: “r”, “g”, “b”, “w” change drawing color to red, green, blue and white accordingly; “e” switches to eraser mode; “space” minimizes oppa; left click on icon in tray restores minimized oppa; “t” toggles transparency and “del” erases all drawing.

Requirements

Oppa currently is developed and tested on Linux using Python 2.7. It requires PyGTK and Pycairo. For drawing in transparent window composited (either using XRender or OpenGL) screen is required - oppa will complain and use only opaque mode without composited screen.

Starting from version 0.5.0 there is experimental support for Windows (Windows 2000 and newer).

Installation

The latest stable version is available to install using pip:

$ pip install oppa

C:\Python27>python.exe ez_setup.py
