This GNU project is an attempt to create a GNU/Linux-friendly version of the Wacom Inkling SketchManager. Instead of integrating with proprietary programs, this program aims to be compatible with free software alternatives like Inkscape.

The program can:

• Display WPI files
• Merge WPI files (command-line only)
• Export to Inkscape SVG (preserving layers), PDF, PNG and JSON
• Convert all WPI files in a directory to SVG
• Automatically assign colors upon pressing the "new layer" multiple times
• Give control over stroke pressure
• Export timing information in JSON
• Interact with the timeline of your drawing
• Use the Wacom Inkling as a mouse device

There's an Inkscape extension available that allows you to open WPI files with Inkscape "directly". The extension uses InklingReader to convert the WPI format to SVG in the background.

Installing the extension is quite easy. Copy the files in res/inkscape-extension to your Inkscape extension directory. On GNU/Linux that is:

~/.config/inkscape/extensions/

The online-mode feature (use the Wacom Inkling as a mouse device) is in a rough shape at the moment. It only works for GNU/Linux because it uses the uinput kernel module. To enable it, you need super user rights (root) to be able to activate the online-mode of the device and to create a virtual mouse device.

Enabling it can be done with the following commands:

su -                # Become a super user
modprobe uinput     # Make sure the uinput kernel module is loaded.
./inklingreader -j  # Start the program with the option to enable online-mode.

Make sure you have the following libraries, development packages and build tools installed:

• GCC or CLANG
• Automake
• Autoconf
• Make
• GTK+ (3.10 or later)
• librsvg-2.0
• libusb 1.0

When you have resolved the dependencies listed above you can build the program by running:

autoreconf -i
./configure
make

To compile with CLANG:

autoreconf -i
./configure CC=clang
make

Additionally you can add compiler flags:

autoreconf -i
./configure CFLAGS="-Wall -O2 -march=native"
make

Optionally you can generate developer documentation using Doxygen.

cd doc/
doxygen

The software is known to run on:

• Debian 7.x
• CrunchBang Linux 11
• Fedora 20 or later
• Mageia 4
• Ubuntu 14.04 or later
• Mac OS X 10.7.5, clang (based on LLVM 3.1svn)
• Windows 8.1 (with MinGW and GTK 32-bit all-in-one bundle)

Since the program uses only widely available libraries it should run OK on almost every GNU/Linux distribution. If you have problems getting it to work on yours, let us know.

InklingReader can use help! If you're interested in helping, here's a list of things you could do:

• Package InklingReader for any distribution
• Request and/or implement features
