hi alp,
i need it to show a resized layout of the complete page that can fit
the screen. iam able to do it right now by giving an alternative
surface and render it in that.
cairo_surface_t *sur
=cairo_image_surface_create(CAIRO_FORMAT_RGB24,frame->view()->contentsWidth(),frame->view(
)->contentsHeight());
cairo_t* cr_sur = cairo_create(sur);
GraphicsContext ctx_sur(cr_sur);
IntRect rect(clip.x, clip.y, frame->view()->contentsWidth(),
frame->view()->contentsHeight());
frame->paint(&ctx_sur, rect);
this seems to be performance intensive, though.
thanks,
Zaheer
