ThorVG  v0.1
ThorVG is a platform-independent portable library for drawing vector-based scene and animation. It's an open-source software that is freely used by a variety of software platforms and applications. ThorVG provides neat and easy APIs, its library has no dependencies and keeps cheap and super compact size. It serves as the vector graphics engine for Tizen OS that powers many products.

Detailed Description

A class that enables initialization and termination of the TVG engines.

Member Function Documentation

◆ init()

static Result init ( CanvasEngine  engine,
uint32_t  threads 
)
staticnoexcept

Initializes TVG engines.

TVG requires the running-engine environment. TVG runs its own task-scheduler for parallelizing rendering tasks efficiently. You can indicate the number of threads, the count of which is designated threads. In the initialization step, TVG will generate/spawn the threads as set by threads count.

Parameters
[in]engineThe engine types to initialize. This is relative to the Canvas types, in which it will be used. For multiple backeneds bitwise operation is allowed.
[in]threadsThe number of additional threads. Zero indicates only the main thread is to be used.
Return values
Result::SuccessWhen succeed.
Result::InsufficientConditionAn internal error possibly with memory allocation.
Result::InvalidArgumentsIf unknown engine type chosen.
Result::NonSupportIn case the engine type is not supported on the system.
Result::UnknownOthers.
Note
The Initializer keeps track of the number of times it was called. Threads count is fixed at the first init() call.

◆ term()

static Result term ( CanvasEngine  engine)
staticnoexcept

Terminates TVG engines.

Parameters
[in]engineThe engine types to terminate. This is relative to the Canvas types, in which it will be used. For multiple backeneds bitwise operation is allowed
Return values
Result::SuccessWhen succeed.
Result::InsufficientConditionIn case there is nothing to be terminated.
Result::InvalidArgumentsIf unknown engine type chosen.
Result::NonSupportIn case the engine type is not supported on the system.
Result::UnknownOthers.
Note
Initializer does own reference counting for multiple calls.
