Mazatech released version 4.5 of AmanithVG SDK on GitHub (http://github.com/Mazatech/amanithvg-sdk), a C/C++ library that implements OpenVG 1.1 specifications from Khronos Group. AmanithVG SDK is features-unlimited and it is free for evaluation purposes. It supports desktop, mobile and embedded platforms: Windows (x86, x86_64), Mac OSX (ub), Linux (arm, arm-v6hf, arm-v7a, aarch64, mipsel, mips64el, pppc64el, x86, x86_64), Android (arm, arm-v7a, arm64-v8a, mips, mips64, x86, x86_64), iOS (ub), QNX (armv7-le, x86). The package also includes a set of ten tutorials covering different OpenVG features: gradients paint types, patterns, stroking, alpha blending, images, masking and text, completed with source code and detailed description on the AmanithVG website. The building system is based on CMake, so all the tutorials support Visual Studio, XCode, Android Studio as well as plain Makefile.
