I'm getting a pixbuf from the backinstore after doing a zoom extents. To avoid modifying the w_current (and the gschem's window flashing), I create a copy of w_current, and work with it. The copy has the same pointers as w_current, as I don't want to copy all the lists (just the TOPLEVEL structure). In the copy of w_current, I create a new drawing area for drawing_area, and a new pixmap for backingstore. With this code, I still see the change to zoom extents and then back to the original zoom in gschem's window when creating the png. I think I should create a new replacement for w_current->window, but I don't see where and how it is initialized. Where is it? Do you think there are more variables which need to be created? By now, the png created has the schematic and some black border (i.e: gschem's window background) all around. I want to remove the border, and I tried to do a zoom box with the coords given by get_complex_bounds. The result was that only the left border was reduced. Do you know how can I do this? Cheers, Carlos
