Header file for CacheMemory class.
Header file for TextReader class.
Header file for ReaderBase class.
All cache managers in libopenshot are based on this CacheBase class.
Definition CacheBase.h:35
This class uses Qt libraries, to create frames with rendered HTML, and return openshot::Frame objects...
void SetJsonValue(const Json::Value root) override
Load Json::Value into this object.
std::shared_ptr< openshot::Frame > GetFrame(int64_t requested_frame) override
Json::Value JsonValue() const override
Generate Json::Value for this object.
CacheBase * GetCache() override
Get the cache object used by this reader (always returns NULL for this object)
std::string Json() const override
Generate JSON string of this object.
void Close() override
Close Reader.
QtHtmlReader()
Default constructor (blank text)
bool IsOpen() override
Determine if reader is open or closed.
void Open() override
Open Reader - which is called by the constructor automatically.
void SetJson(const std::string value) override
Load JSON string into this object.
std::string Name() override
Return the type name of the class.
This abstract class is the base class, used by all readers in libopenshot.
Definition ReaderBase.h:76
This namespace is the default namespace for all code in the openshot library.
Definition Compressor.h:29
GravityType
This enumeration determines how clips are aligned to their parent container.
