Plugin : output image + structure Hey ! I'm working on a OpenCV plugin and I (now, finally !) manage to output an image from it, but now I would like to output both image and structure but it doesn't work. I have this message : -[HandTrackingPlugIn setOutputHands:]: unrecognized selector sent to instance My image provider is kind of ugly and I'm afraid that is the reason, but... Here's the code : Bla bla bla...
double centerX = ((r->x + r->width / 2) * scale);
double centroidX = (width / (double)[imgCV getSize].width * centerX) - (width / 2.f);
double centerY = ((r->y + r->height / 2) * scale);
double centroidY = (height / (double)[imgCV getSize].height * centerY) - (height / 2.f);
[hands addObject:[NSArray arrayWithObjects:
[NSNumber numberWithDouble:centroidX],
[NSNumber numberWithDouble:centroidY],
nil]];
}
cvClearMemStorage(cstorage);
cvReleaseMemStorage(&cstorage);
cvClearMemStorage(hstorage);
cvReleaseMemStorage(&hstorage);
[imgLittle release];
}
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glClearColor(0., 0., 0., 0.);
glLoadIdentity();
glPushAttrib(GL_ENABLE_BIT | GL_TEXTURE_BIT);
glPushClientAttrib(GL_CLIENT_PIXEL_STORE_BIT);
GLuint tex = [imgCV generateTextureInContext:cgl_ctx];
self.outputImage = [context outputImageProviderFromTextureWithPixelFormat:pixelFormat
pixelsWide:[imgCV getSize].width
pixelsHigh:[imgCV getSize].height
name:tex
flipped:YES
releaseCallback:textureReleaseCallback
releaseContext:NULL
colorSpace:CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB)
shouldColorMatch:YES];
glPopClientAttrib();
glPopAttrib();
self.outputHands = hands;Any idea of what's happening ? I'm very bad at understanding OpenGL and image providers... Thank you !

Oooppsss... Sorry... I was outputing an NSMutableArray...
