I can grab the main window contents using the gdk_pixbuf_get_from_drawable
function & then get a pointer to the raw pixels. I guess the way that call
is used, creates a pixmap, makes copies of the data etc..etc
Anybody know of a leaner way to grab the pixel data?
--------------------------------------------
In mozilla-1.7.12/widget/src/gtk2/nsWindow.cpp
nsWindow::OnExposeEvent(GtkWidget *aWidget, GdkEventExpose *aEvent)
{
// copy from surface to pixbuf
GdkPixbuf * pb = gdk_pixbuf_get_from_drawable(NULL,
mDrawingarea->inner_window,
0,
0,0, 0,0,
width, height);
unsigned char *pixels=gdk_pixbuf_get_pixels(pb);

Hi,
I'm embedding mozilla in a linux application & want to read the main
display buffer that mozilla uses & convert that to an opengl Texture. Am
using the Mozilla-1.7.12/../GtkMozEmbed library.
I see that there are multiple nsRenderingContextGTK instacnes which each
all have a part of the page in the offscreen buffer. I'm also looking at
nsViewManager which calls refresh on each of the rendering contexts. But
so far, i've not found the main/composite buffer that holds the entire
page.
Anyone have have any tips?
Thanks
