Hmm. Right, this is what we won't be doing!
The call you need is to
public int getScreenWidth() {
return dimScreen.width;
}
public int getScreenHeight() {
return dimScreen.height;
}
in Viewer. That is, use
int screenWidth = viewer.getScreenWidth();
int screenHeight = viewer.getScreenHeight();
If you are doing this via the command line, all you would do is set the
screen width ahead of time. Still, I see your point - that it could be
part of the WRITE command. We do that already for images, of course. In
any case, Eval will take care of that if we need it to.
Regarding Exporter.initialize() --- I think where you want this is in
PovrayExporter.getHeader():
Date now = new Date();
SimpleDateFormat sdf =
new SimpleDateFormat("EEE, MMMM dd, yyyy 'at' h:mm aaa");
String now_st = sdf.format(now);
Etc. All this stuff will go in getHeader() in a slightly different form:
out("//******************************************************\n");
out("// Jmol generated povray script.\n");
out("//\n");
out("// This script was generated on :\n");
out("// " + now_st + "\n");
out("//******************************************************\n");
out("\n");
out("\n");
out("//******************************************************\n");
out("// Declare the resolution, camera, and light sources.\n");
out("//******************************************************\n");
out("\n");
out("// NOTE: if you plan to render at a different resolution,\n");
out("// be sure to update the following two lines to maintain\n");
out("// the correct aspect ratio.\n" + "\n");
out("#declare Width = "+ screenWidth + ";\n");
out("#declare Height = "+ screenHeight + ";\n");
out("#declare minScreenDimension = " + minScreenDimension + ";\n");
out("#declare Ratio = Width / Height;\n");
out("#declare zoom = " + zoom + ";\n");
In fact, you could just add to PovrayExporter:
private void out(String line) {
output.append(line);
}
if you like.
You can get the zoom setting from viewer.getZoomPercentFloat();
etc. So this is your job! :)
