QtImageReader::QtImageReader | ( | string | path | ) |
Constructor for QtImageReader. This automatically opens the media file and loads frame 1, or it throws one of the following exceptions.
Definition at line 44 of file QtImageReader.cpp.
QtImageReader::QtImageReader | ( | string | path, |
bool | inspect_reader | ||
) |
Constructor for QtImageReader. This only opens the media file to inspect it's properties if inspect_reader=true. When not inspecting the media file, it's much faster, and useful when you are inflating the object using JSON after instantiating it.
