Hi,
I'm looking at your product for a potential customer. But the key point to the buy decision is how to extract clean text out of the EMF file.
I'm using the following code snipet:
FileInputStream file = new FileInputStream(fileName);
EmfMetafile efile = new EmfMetafile(file);
MetafileComment[] metaFileComment = efile.getComments();
for (int i = 0; i < metaFileComment.length; i++) {
String temp = Charset.defaultCharset().decode(ByteBuffer.wrap(metaFileComment[i].getCommentData())).toString().replaceAll("[\u0000-\u001F]", "").replaceAll("[\u007A-\uFFFF]", "");
if (temp.indexOf("F+@") == -1 && temp.indexOf("*>*>?@,") == -1) {
temp = temp.substring(temp.indexOf("*>*>?@") + 6);
System.out.println(" -- metaFileComment " + metaFileComment[i].getRecordIndex() + ": " +
temp );
}
}
By doing the above text stripping, I was able to remove some of the junks text. However, there are still alot more which I have no idea how to filter it out.
Here's a sample output when I ran it (please note, I'd like to extract "cleanly" only the text in RED color below).
