Elektronické podpisy metadat pro dokument Bmp prostřednictvím Java jsou jednoduché a snadno se používají!

        
// Set up input Bmp file
String filePath = "input.bmp";
// Set up output file
String outputFilePath = "output.bmp";

// Instantiate Signature for input file
Signature signature = new Signature(filePath);

// instantiate metadata signing options
MetadataSignOptions options = new MetadataSignOptions();

// Specify different Metadata Signatures and add them to options signature collection
// set start id
int imgsMetadataId = 41996;
// setup int value
ImageMetadataSignature mdSign_DocId = new ImageMetadataSignature(imgsMetadataId++, 123456); // int
options.getSignatures().add(mdSign_DocId);
// setup Author property
ImageMetadataSignature mdSign_Author = new ImageMetadataSignature(imgsMetadataId++, "Mr.Scherlock Holmes"); // string
options.getSignatures().add(mdSign_Author);
// setup data of sign date
ImageMetadataSignature mdSign_Date = new ImageMetadataSignature(imgsMetadataId++, new Date()); // DateTime
options.getSignatures().add(mdSign_Date);
// setup double
ImageMetadataSignature mdSign_Amnt = new ImageMetadataSignature(imgsMetadataId++, 123.456); //decimal value
options.getSignatures().add(mdSign_Amnt);

// sign Bmp document
SignResult result = signature.sign(outputFilePath, options);
