Detailed Description

This class uses the Qt library, to open image files, and return openshot::Frame objects containing the image.

// Create a reader for a video
QtImageReader r("MyAwesomeImage.jpeg");
r.Open(); // Open the reader
// Get frame number 1 from the video
tr1::shared_ptr<Frame> f = r.GetFrame(1);
// Now that we have an openshot::Frame object, lets have some fun!
f->Display(); // Display the frame on the screen
// Close the reader
r.Close();

Member Function Documentation

void QtImageReader::Close ( )

virtual

Close File.

Implements openshot::ReaderBase.

Definition at line 89 of file QtImageReader.cpp.

Cache* openshot::QtImageReader::GetCache ( )

inlinevirtual

Get the cache object used by this reader (always returns NULL for this object)

Implements openshot::ReaderBase.

Definition at line 86 of file QtImageReader.h.

tr1::shared_ptr< Frame > QtImageReader::GetFrame	(	long int	requested_frame	)
throw	(	ReaderClosed
	)

virtual

Get an openshot::Frame object for a specific frame number of this reader. All numbers return the same Frame, since they all share the same image data.
