wasawi / ofximagesequenceplayback

An openFrameworks addon used in conjunction with ofxImageSequence for robust control over a sequence: play, reverse, loop, and ping pong and more.

ofxImageSequencePlayback

An openFrameworks library for managing sequences of ofImages in a more robust way. ofxImageSequencePlayback is dependant on the awesome ofxImageSequence addon by Flightphase.

It is also heavily informed by the great work done by Red Paper Heart on their Cinder Block, rph-textureSequence. This addon is as much a port of their Cinder Block as anything.

Features

• Play sequences in reverse.
• Loop the infinitely.
• Ping pong the sequences (forward->reverse->forward->reverse...)
• Notifications when a sequence completes and is not looping.
• Pausing, Stopping, changing FPS of a sequence.

Simple Example

Assuming you have a folder in your data directory named "sequence" filled with PNGs...

In your .h file:

ofxImageSequencePlayback mySequence;
void onSequenceCompleted(ofEventArgs &evt);

In your .cpp file:

void testApp::setup() {
	mySequence.loadSequence("sequence",24.0f); // 24 FPS

	ofAddListener(mySequence.sequenceCompleted,this,&testApp::onSequenceCompleted);

	mySequence.play();
}

void testApp::onSequenceCompleted(ofEventArgs &evt) {
    mySequence.stop();
    ofLog(OF_LOG_VERBOSE,"The sequence is complete.");
}

void testApp::update() {
	mySequence.update();
}

void testApp::draw() {
	mySequence.draw();
}
