Getting started

Have a look at the sample project to get started directly and have a small explanation here.

Settings

The module can be configured in the settings.json.

{
    "Canon":{
        "mirrorX":true,
        "mirrorY":true,
        "streamingMethod": "both",
        "rotate":90
    }
}

property	type	description
mirrorX	boolean	mirrors Image on x-axis
mirrorY	boolean	mirrors Image on y-axis
rotate	int	rotate the image either 0, 90, 180 or 270
streamingMethod	string	transmit type of images to other modules either "texture","pixels" or "both"

Communication

Control the module

Activate/ deactivate live-view:

ofJson j;
j["value"] = false; // activate the module, for deactivate use true
notifyEvent("setIdle", j);

Take photo:

notifyEvent("capture");

Get messages from the module

Depending of the selected streaming method you receive the cam image as ofTexture or ofPixels. A photo arrives at the address photo, other messages represent the current live view.

void Presenter::proceedModuleEvent(ModuleEvent& e) {
		
		// update the cam image 
		if (e.type == ModuleEvent::MODULE_EVENT_TEXTURE) {
			if (e.address == "photo") {
				highResTexture = e.texture;
			}else{
				lowResTexture = e.texture;
			}
			else  camTexture = e.texture;
		}else if (e.type == ModuleEvent::MODULE_EVENT_PIXELS) {
			if (e.address == "photo") {
				highResImage.setFromPixels(*e.pixels);
			} else  {
				lowResImage.setFromPixels(*e.pixels);
			}
		}
    }
