GIF Format Options

Question

I'm trying to add GIF settings for Save for Web and Devices to a script I have.  It has 2 different areas for FileSaveOptions (shown below).  Can someone please tell me how or where do I tell the script to incorporate each of the settings in the attached example?
self.gifTransparency = true;
self.gifInterlaced = false;
case "gif": {
      saveOpts.transparency = toBoolean(fsOpts.gifTransparency);
      saveOpts.interlaced = toBoolean(fsOpts.gifInterlaced);
      saveOpts._convertToIndexed = true;
      saveOpts._flatten = true;
      saveOpts._8Bit = true;
      break;

Answer 1

Yes, you can set lossy with the Object Model.
var gifOptions = new ExportOptionsSaveForWeb();
gifOptions.colorReduction = ColorReductionType.SELECTIVE;// the default  enumeration
gifOptions.PNG8 = true;// needed to force index mode
gifOptions.colors = 256;// the default value
gifOptions.dither = Dither.DIFFUSION;
gifOptions.ditherAmount = 100;// the default value
gifOptions.transparency = true;// default = false
gifOptions.lossy = 10;// default = 0;
Just to be clear, once you have the code from the scriptlistener log you can use that in your script.
