Hello,
I have an application which uses GTK-Plot in following manner:
canvas = gtk_plot_canvas_new()
my_plot = gtk_plot_new_with_size()
child = gtk_plot_canvas_plot_new(my_plot)
gtk_plot_canvas_put_child(canvas,child)
however,
I can capture the visible plot with gdk_pixbuf_get_from_drawable from the canvas and convert it to a
PNG-Image.
But now I want to export the plot without showing it before.
The Plot should be just created for this export with some special options and
is destroyed afterwards.
I am a little bit confused about canvas, gtk-plot-canvas, pixbufs, pixmaps, drawables, what is shown
and when something is rendered.
Can I create a gdk-pixbuf and using the gtk-plot functions to draw directly
into it?
I read something about gdk-pixmap, but I don't know how I can tell the gtk-plot functions to uses
this as canvas.
Any other Ideas?
regards
Arne
