Get started

• Download or clone this repository
• Run git submodule update --init for fetching dependencies
• Install conan package manager. Installations steps
  • Add bincrafters package source, run:
  • conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
• Create directories for the corresponding build configuration. For instance, for MSVC x64DebugBuild the following structure should be prepared:
  • {project_directory}/build_simulator/x64-DebugTest
• Configure project
  • navigate to the created {project_directory}/build_simulator/x64-DebugTest
  • run conan install ../..
  • run cmake -G"Visual Studio 16 2019" -Ax64 ../..
  • run cmake --build .
  • After the build navigate into bin directory and launch RlottieLvgl.exe

Use Rlottie from external file

lv_obj_t* rlottie_animation = lv_rlottie_create_from_file(parent,width,height, "Path/to/resource/insta_camera.json");

Use Rlottie from raw string data

//Create characters array for the image data
static const char FingerprintRaw[] ="{\"v\":\"5.1.16\",\"fr\":60,\"ip\":0,\"op\":154,\"w\":800,\"h\":600,\"nm\":\"Fingerprint... a lot of JSON items";

// Use it with corresponding API function
lv_obj_t* rlottie_anim_fingerprint_raw = lv_rlottie_create_from_raw(parent, width, height, FingerprintRaw);

JSON escaping

For using raw strings it's necessary to escape an image data. For this purpose the following escape tool can be used:
