TouchVG is a lightweight 2D vector drawing framework for iOS, Android and Windows.

Features described in Online document.

This is an open source LGPL 2.1 licensed project. It uses the following open source projects:

• TouchVGCore (LGPL): Cross-platform vector drawing libraries using C++.
• svg-android (Apache): Vector graphics support for Android.
• SVGKit (MIT): Display and interact with SVG Images with CoreAnimation on iOS.
• simple-svg (BSD): A C++ header file for creating SVG files.
• rapidjson (MIT): A fast JSON parser/generator for C++ with both SAX/DOM style API.
• x3py (Apache): Compile script files.
• SWIG (GPL): Use the tool to generate the glue code for Java and C#.
• iOS-Universal-Library-Template: Use it to create static library project.
• Algorithms: NearestPoint.c, Bezier's bound box, The intersection of two circles, Position judgment and Fitting digitized curves.

• Import all projects under ./android directory of TouchVG in eclipse, then build touchvg project.

  • Android SDK version of the projects may need to modify according to your installation.
  • Recommend using the newer ADT Bundle to avoid complex configuration.

• To regenerate libtouchvg.so, please enter android directory of TouchVG, then type ./build.sh (Need to add the NDK installation location to your PATH environment variable).

  • Type ./build.sh -B to rebuild the native libraries.

  • Type ./build.sh APP_ABI=x86 to build for the x86 (Intel Atom) Emulator.

  • If the error build/gmsl/__gmsl:512: *** non-numeric second argument to wordlist function occurs, then open the build/gmsl/__gmsl file in the NDK installation directory, and change line 512 to: int_encode = $(__gmsl_tr1)$(wordlist 1,$(words $1),$(__gmsl_input_int))

  • MSYS and TDM-GCC(a MinGW distribution) are recommended on Windows.

  • To regenerate the kernel JNI classes, type ./build.sh-swig (Need to install SWIG, and add the location to PATH).

TouchVG is available on CocoaPods. Just add the following to your project Podfile:

pod 'TouchVG', '~> 1.1.10'

Or use the develop version:

pod 'TouchVG', :podspec => 'https://raw.githubusercontent.com/touchvg/TouchVG/develop/TouchVG.podspec'

Or add the following to use SVG rendering feature with SVGKit:

pod 'TouchVG-SVG', :podspec => 'https://raw.githubusercontent.com/touchvg/TouchVG/develop/ios/TouchVG-SVG.podspec'

Then type pod install or pod install --no-repo-update. Need to remove libPods-TouchVG.a or libPods-TouchVG-TouchVG-SVG.a from Link Binary With Libraries. Remove -lxml2 from Other Linker Flags for TouchVG-SVG target.

Alternatively, you can build as one of the following methods:

• Open TouchVG.xcworkspace in Xcode, then build the TouchVG or TouchVG-SVG target.

  • libTouchVG.a does not support SVG display.
  • libTouchVG-SVG.a can display SVG shapes using SVGKit.

• Or enter ios directory and type ./build.sh to compile static libraries to the ios/output directory.

  • Type ./build.sh -arch arm64 to make for iOS 64-bit.
  • Type ./build.sh clean to remove object files.

• Open wpf/Test_cs10.sln in Visual Studio 2010 (Need VC++ and C#). Or open wpf/Test_cs9.sln in VS2008.

• To regenerate wpf/touchvglib/core/*.cs, please enter wpf directory and type ./build.sh (Need to install SWIG, and add the location to PATH).

• You can compile TouchVG for Python, Perl or Java applications on Linux, MinGW or Mac OS X.

  • Enter core directory which contains Makefile, then type the following make command:

    • Make all install: compile C + + static library .
    • Make java: Jar package and generate dynamic libraries for Java programs.
    • Make python, make perl: namely Python, Perl , etc. to generate class files and dynamic libraries.
    • Make clean java.clean python.clean: delete these temporary files compiled out .

  • MSYS and TDM-GCC(a MinGW distribution) are recommended on Windows.

• You can use newproj.py to create library project containing your own shapes and commands. So the TouchVG and TouchVGCore libraries does not require changes.

  • Checkout and enter DemoCmds directory, then type python newproj.py YourCmds:

    git clone https://github.com/touchvg/DemoCmds.git
    cd DemoCmds
    python newproj.py MyCmds

  • Need to install python to run the script.
