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 5.9 or newer (QtGui not required for headless server)
• KF5 Extra CMake Modules
• KF5 KArchive

Client specific dependencies:

• QtColorPicker: optional, bundled copy is included
• QtKeyChain: optional, enables password storage
• KF5 KDNSSD: optional, local server discovery with Zeroconf
• MiniUPnP: optional, automatic port forwarding setup
• GIFLIB: optional, animated GIF export
• LibVPX: optional, WebM video export

Server specific dependencies (you can also take a look at Docker build script):

• libsystemd: optional, systemd socket activation support
• libmicrohttpd: optional, HTTP admin API
• libsodium: optional: ext-auth support

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)
• KIS_TABLET=on: enable improved graphics tablet support (taken from Krita)

Notes about KIS_TABLET:

• On Windows, it enables Windows Ink and improved Wintab support. A patched version of Qt should be used. See pkg/win for the patch.
• On Linux (or any platform with an X server,) it enables a modified XInput2 event handler.
• On macOS it does nothing and shouldn't be used.

Example: $ cmake .. -DCMAKE_BUILD_TYPE=debug -DKIS_TABLET=on
