Hi.
I tried to add the image in two ways... But it doesn't work at all!
beginEditCP(imf);
imf->addImage( image, position );
endEditCP(imf);
In this first case the image is not updated when I modify it...
beginEditCP(imf, ImageForeground::ImagesFieldMask);
imf->addImage( image, position );
endEditCP(imf, ImageForeground::ImagesFieldMask);
In this case the image is not visible!
Here there is all the code... I hope somebody sees an error! Anyway, thanks for
your help.
addForeground( ViewportPtr viewportRight, ViewportPtr viewportLeft, string
label )
{
//addForeground is called continuously. We use this counter to add
image and foreground only the first time
static int first = 0;
// Create the new image
Text2d *oText = new Text2d( makeCoredNode<Group>() );
oText->createLabel( label, 26 );
oText->setLabelPosition(Pnt3f(0.0f,0.0f,0.0f),0);
image = oText->getImage();
if (first<1)
{
beginEditCP(imf, ImageForeground::ImagesFieldMask);
imf->addImage( image, position );
endEditCP(imf, ImageForeground::ImagesFieldMask);
beginEditCP( viewportRight);
viewportRight->getForegrounds().push_back(imf);
endEditCP( viewportRight);
beginEditCP( viewportLeft);
viewportLeft->getForegrounds().push_back(imf);
endEditCP( viewportLeft);
first++;
}
delete oText;
}
Cheers,
Antonio
