gf_display_snapshot on non Fujitsu Carmine hardware

Hi All,

The API doc for gf_display_snapshot() (part of AGTDK) says that this functionality works only on Fujitsu Carmine 
hardware. Is there any alternative to achieve the same functionality - basically get a pic of the stuff shown onscreen?

Thanks in advance for your assistance,

Srinivas

yeah, that is just a specific h/w capability of the carmine ... you can simulate this by attaching to the main display, 
creating another surface of same stride, width and height, then use gf_draw_blit2() and send a copy to your screen.  I 
would waiting for hardware idle before doing so.  You can then populate a img_t, and call img_write() if you want to go 
that far - data from gf_surface_get_info() using your secondary surface.

Hi Derek,
Thanks for the response!

Would this be possible if the process trying to create the image files is different from the processes actually doing 
the painting/drawing on screen? And could you please enlighten me on "waiting for hardware idle"?

Many thanks once again,
Srinivas
