Drawpile - a collaborative drawing program

Drawpile is a drawing program that lets you share the canvas with other users in real time.

Some feature highlights:

• Runs on Linux, Windows and OSX
• Shared canvas using the built-in server or a dedicated server
• Record, play back and export drawing sessions
• Simple animation support
• Layers and blending modes
• Text layers
• Supports pressure sensitive Wacom tablets
• Built-in chat
• Supports OpenRaster file format
• Encrypted connections using SSL
• Automatic port forwarding with UPnP

Building with cmake

Common dependencies:

• Qt 5.5 or newer (QtGui not required for headless server)
• KF5 KArchive

Client specific dependencies:

• QtColorPicker
• KF5 KDNSSD (optional: local server discovery with Zeroconf)
• GIFLIB (optional: animated GIF export)
• MiniUPnP (optional: automatic port forwarding setup)

Server specific dependencies:

• libsystemd (optional: systemd socket activation support)
• libmicrohttpd (optional: HTTP admin API)

It's a good idea to build in a separate directory to keep build files separate from the source tree.

Example:

$ mkdir build
$ cd build
$ cmake ..
$ make

The executables will be generated in the build/bin directory. You can run them from there, or install them with make install.

The configuration step supports some options:

• CLIENT=off: don't build the client (useful when building the stand-alone server only)
• SERVER=off: don't build the stand-alone server.
• SERVERGUI=off: build a headless-only stand-alone serveer.
• TOOLS=on: build dprec2txt command line tool
• CMAKE_BUILD_TYPE=debug: enable debugging features
• INITSYS="": select init system integration (currently only "systemd" is supported.) Set this to an empty string to disable all integration.
• TESTS=on: build unit tests (run test suite with make test)

Example: $ cmake .. -DCMAKE_BUILD_TYPE=debug
