Working Example for as3-xmp library

Question

I tried using the AS3-XMP Library to read metadata of the files, but i have no idea what methods to use.

Anyway one has any working example? so that i could learn from it? i manage to read all the TIFF structure / tags data, but i would like to know how to write it.

Answer 1

Did you follow all instructions here? Review the init function of the code sample for "how do I use this" reasons.

I'll repeat the full instructions below:

1. Download the as3_xmp_file, as3crypto and XMPCore libs
2. Import the Flex Project archive files
3. In the as3_xmp_file project under "Project" -> "Properties" -> "Build Path" -> "Library path" choose "Add project" and add the "XMPCore" project
4. Create a new desktop application project
5. In the new project under "Project" -> "Properties" -> "Build Path" -> "Library path" choose "Add project" and add the "as3_xmp_file" and "XMPCore" projects
6. Insert the following source into your new projects main mxml file

<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()">
  <mx:Script>
    <![CDATA[
      import de.qwesda.as3_xmp_file.as3_xmp_file;
      import com.adobe.xmp.*;

      private function init():void {
        var file1:as3_xmp_file = new as3_xmp_file(File.desktopDirectory.nativePath + "/test.jpg");

        if(file1.file.exists){
          trace(file1.xmp.dumpObject());

          var dc_exif:Namespace = XMPConst.dc;

          file1.xmp.dc_exif::title = "Title";

          file1.save();
        }

        var file2:as3_xmp_file = new as3_xmp_file(File.desktopDirectory.nativePath + "/test.jpg");

        if(file2.file.exists){
          trace(file2.xmp.dumpObject());
        }
      }
