Accessing Bridge thumbnail image?

[Mike Hale]

I ran across a blog post that says that makes it sound like there is a script that will sent an email using the thumbnail, no the full image. So it can send a small jpeg without needing to resize and/or convert formats in photoshop.

I don't want to email but I like the idea of getting a small jpeg version of an image.

Anyone have any idea of how that is done. I don't do much Bridge scripting. I know how to point Bridge at a file and access the thumbnail. It the getting the thumbnail image that has be at a loss.

Here's some code from a script I wrote. It saves a Thumbnail as a jpeg. The parameters should be obvious. There may be stuff missing, but this should get you pointed in the right direction.

Code: Select allBridgeLib.saveAsJPEG = function(th, file, width, height, quality) {
  var bm = new BitmapData(th.spec);
  var ns = "http://ns.adobe.com/tiff/1.0/";
  var rc = false;

  try {
    if (th.hasMetadata) {
      // this lovely bit of code handles images that are rotate
      // in the metadata but not on the disk
      var md;
      if (DEV) {
        md = th.metadata;
      } else {
        md = th.synchronousMetadata;
      }

      if (md) {
        md.namespace = ns;
        var rotate = md["Orientation"];

        if (rotate && rotate.match(/rotate/i)) {
          var m = rotate.match(/(-)?(\d+)/);
          if (m) {
            var deg = toNumber(m[2]);
            if (m[1] == '-') {
              deg = -deg;
            }

            var nbm = bm.rotate(deg);
            if (nbm) {
              bm = nbm;
            }
          }
        }
      }
    }
  } catch (e) {
    var msg = Stdlib.exceptionMessage(e);
    Stdlib.log(msg);
    alert(msg);
    return false;
  }

  if (height == undefined) {
    height = width;
  }

  if (width) {
    var size = width;

    if (width != height) {
      var rat = height/width;
      var irat = bm.height/bm.width;

      // var size;
      if (rat > irat) {
        size = Math.max(width, Math.floor(width * irat));

      } else {
        size = Math.max(height, Math.floor(height/irat));
      }
    }

    var nbm = bm.resize(toNumber(size));
    if (nbm) {
      bm = nbm;
    }
  }

  file.remove();
  bm.exportTo(file, quality);

  var rc = BridgeLib.waitForFile(file, BridgeLib.DEFAULT_BT_TIMEOUT);
  return rc;
};

BridgeLib.waitForFile = function(file, timeout) {
  var parts = 20;

  if (timeout > 20) {
    parts = Math.ceil(timeout/2);
  }

  var timer = (timeout / parts) * 1000;

  while (!file.exists && parts) {
    $.sleep(timer);
    parts--;
  }

  return file.exists;
};

There is an example here as well Mike.

Thanks guys. One last question( I hope ). If I don't care about rotating can I skip the metadata and get jpegs of non bitmaped docs like ai, indesign, pdf, etc?

Have a look at this and see if it will fit the bill....

Uh, that's an interesting script. But it does show how to get at the thumbnails and previews directly of they're available.

And the FileRenamer code looks like an interesting approach to that problem.
