Required Addons

• ofxModule
• ofxGphoto

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.

{
    "Gphoto":{
		"deviceName": "Fujifilm XT-2",
        "mirrorX":true,
        "mirrorY":true,
        "streamingMethod": "both",
        "rotate":90
    }
}

property	type	description
deviceId	int	sets device ID (search order of gphoto, can change on restart)
deviceName	string	name of the device as shoen in device list
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);
			}
		}
    }
