hi!

I’ve modified a patch posted by nesa 1 year ago for nose tracking. I simply want to replace my cv.jit.track point on the nose with a black rectangle (pict). getting a box out of cv.jit.track is easy, so

this: http://jonaswolf.com/lcd_framerect.tiff

leads to that: http://jonaswolf.com/draw_rect.tiff

but when trying to replace my box by a black rectangle (pict)

this: http://jonaswolf.com/lcd_pict.tiff

leads to that: http://jonaswolf.com/draw_pict.tiff

bg turns white, the section that should replace my nose on the contrary the only thing visible..

what did I miss on?

cheers!

Hi,

As I wrote in a previous thread, the documentation about the drawpict command isn’t perfectly clear or accurate, you have to format your message left, top, width, height instead of left, top, right, bottom as I think you’re doing.
