[jira] Created: (SANSELAN-18) Sanselan 0.97 - GIF Parser facilities
return null values for xmp
Sanselan 0.97 - GIF Parser facilities return null values for xmp
----------------------------------------------------------------
Key: SANSELAN-18
URL: https://issues.apache.org/jira/browse/SANSELAN-18
Project: Sanselan
Issue Type: Bug
Environment: Windows XP, JDK 1.5
Reporter: Kelly Boettcher
When attempting to use both core Sanselan methods and GIFParser methods, attempts to retrieve XMP is resulting in null values. Example code below:
File file;
InputStream is;
byte[] b;
file = new File("C:/data/test.gif");
is = new FileInputStream(file);
b = new byte[is.available()];
is.read(b);
is.close();
/* Testing the Sanselan getXMP */
String xmp = Sanselan.getXmpXml(file); // returns null
System.out.println(xmp);
/* Testing the GIF image parser's xmp capabilities */
GifImageParser parser = new GifImageParser();
ByteSource bs = new ByteSourceArray(b);
String existingXMP = parser.getXmpXml(bs, null); // returns null
System.out.println(existingXMP);

-----------------------------------------
But doesn't the fact that I can see metadata within Adobe Photoshop mean that I should be returning some sort of xmp values? Perhaps not. Ok, can you point me in the direction of xmp write back facilities for GIF format?

----------------------------------------------
getXmpXml() returns null if no XMP data is found in the image file.
Also, you might be seeing an issue due to the way you're reading your file. is.read() isn't guaranteed to read the entire stream - you'll need to loop read()s. You're also not buffering the stream, which makes a significant performance difference. Sanselan's ByteSources deal with these issues; I suggest the much easier:
File file = new File("C:/data/TestGIF.gif");
String xmp = Sanselan.getXmpXml(file);
if(null != xmp) {
System.out.println(existingXMP);
} else {
System.out.println("Image contains no xmp data.");
}
