Hello, AFAIK, I don't think the function is in DD::Image. The one in Denoise renders the text over a semi-opaque red bar in OpenGL manually. Specifically, it sets the projection matrix of the ViewerContext to be orthographic, draws a red bar of viewer width, and uses DD::Image's gl_text() function to draw the text.
Hope that helps, Dan.
