    Load Existing Email Message and Modify its Contents inside Android Apps

    This technical tip shows how to load any existing email message and modify its contents before saving it back to disk using Aspose.Email for Android API. To do this successfully, specify the MessageFormat when loading the email message from disk. In addition, it is important to specify the correct MailMessageSaveType when saving the message back to
    public static void UpdateAndSaveEmail()
        // Base folder for reading and writing files
    String  strBaseFolder  = Environment.getExternalStorageDirectory().getPath();
    strBaseFolder = strBaseFolder + "/";
        //Initialize and load an existing MSG file by specifying the MessageFormat
    MailMessage email = MailMessage.load(strBaseFolder + "anEmail.msg", MessageFormat.getMsg());
        //Initialize a String variable to get the Email Subject
        String subject = email.getSubject();
        //Append some more information to Subject
    subject = subject + " This text is added to the existing subject";
        //Set the Email Subject
        //Initialize a String variable to get the Email's HTML Body
        String body = email.getHtmlBody();
        //Apppend some more information to the Body variable
    body = body + "<br> This text is added to the existing body";
        //Set the Email Body
        //Initialize MailAddressCollection object
    MailAddressCollection contacts = new MailAddressCollection();
        //Retrieve Email's TO list
    contacts = email.getTo();
        //Check if TO list has some values
    if (contacts.size() > 0)
            //Remove the first email address
            //Add another email address to collection
        //Set the collection as Email's TO list
        //Initialize MailAddressCollection
    contacts = new MailAddressCollection();
        //Retrieve Email's CC list
    contacts = email.getCC();
        //Add another email address to collection
        //Set the collection as Email's CC list
        //Save the Email message to disk by specifying the MessageFormat + "message.msg", MailMessageSaveType.getOutlookMessageFormat());

    Java code for Changing Color Space of PDF Document

    This code shows how java developers can change color space of PDF document from RGB color to CMYK and vice versa by using Aspose.PDF for Java Library. The following methods have been implemented in the Operator class for changing colors. Use it to change some specific RGB/CMYK colors to CMYK/RGB color space, keeping the remaining PDF document as it
    Document doc = new Document(myDir + "input_color.pdf");
    OperatorCollection contents = doc.getPages().get_Item(1).getContents();
    System.out.println("Values of RGB color operators in the pdf document");
    for (int j = 1; j <= contents.size(); j++)
    	Operator oper = contents.get_Item(j);
    	if (oper instanceof Operator.SetRGBColor || oper instanceof Operator.SetRGBColorStroke)
    	try {
    	    //Converting RGB to CMYK color
    	    double[] rgbFloatArray = new double[]
    	    double[] cmyk = new double[4];
    	    if (oper instanceof Operator.SetRGBColor)
    		((Operator.SetRGBColor)oper).getCMYKColor(rgbFloatArray, cmyk);
    		contents.set_Item(j, new Operator.SetCMYKColor(cmyk[0], cmyk[1], cmyk[2], cmyk[3]));
    		else if (oper instanceof Operator.SetRGBColorStroke)
    		    ((Operator.SetRGBColorStroke)oper).getCMYKColor(rgbFloatArray, cmyk);
    		   contents.set_Item(j, new Operator.SetCMYKColorStroke(cmyk[0], cmyk[1], cmyk[2], cmyk[3]));
    throw new java.lang.Throwable("Unsupported command");
    	} catch (Throwable e) {
    		        } + "input_colorout.pdf");
    //Testing the result
    System.out.println("Values of converted CMYK color operators in the result pdf document");
    doc = new Document(myDir + "input_colorout.pdf");
    contents = doc.getPages().get_Item(1).getContents();
    for (int j = 1; j <= contents.size(); j++)
    	Operator oper = contents.get_Item(j);
    	if (oper instanceof Operator.SetCMYKColor || oper instanceof Operator.SetCMYKColorStroke)

    Java Code Sample to Create PDF from HTML Using REST API

    This code sample shows how Java developers can create PDF file from HTML using Aspose.Pdf for Cloud API in their REST applications.
    //build uri to create empty pdf
        String strURI = "";
        String signedURI = Sign(strURI);
    InputStreamresponseStream = ProcessCommand(signedURI, "PUT");
        String strJSON = StreamToString(responseStream);
    Gsongson = new Gson();
        //Parse the json string to JObject and Deserializes the JSON to a object.
    BaseResponsebaseResponse = gson.fromJson(strJSON,BaseResponse.class);
    if (baseResponse.getCode().equals("200") &&baseResponse.getStatus().equals("OK"))
    System.out.println("Empty PDF file has been created successfully");
    //Here is the BaseResponse class
    public class BaseResponse {
    	publicBaseResponse() { }
    	private String Code;
    	private String Status;
    	public String getCode(){return Code;}
    	public String getStatus(){return Status;}
    	public void  setCode(String temCode){ Code=temCode;}
    	public void setStatus(String temStatus){ Status=temStatus;}

    How to Convert MemoryStream Image to PDF inside Android Applications

    This technical tip shows how developers can convert MemoryStream image to PDF file inside their Android application. The Image class in Aspose.Pdf makes it possible to convert an image from various sources into PDF format. This may include an image from particular location over the hard-drive, an image from MemoryStream or an image at a web locatio
    try {
         // Create PDF document
    Pdfpdf = new Pdf();
         // Add a section into the PDF document
         Section sec1 = pdf.getSections().add();
    byte[] fileArray = null;
         //	Get the Image contents into Byte Array
    try {
    fileArray = getBytesFromFile(new File("/mnt/sdcard/Aspose.jpg"));
             } catch (IOException e) {
         // Create an image object in the section
    aspose.pdf.Image img1 = new aspose.pdf.Image(sec1);
         // Add image object into the Paragraphs collection of the section
         // Set the Image file type
         // Create a BinayFileStream Object to hold byte array
    BinaryFileStreambstream = new BinaryFileStream(fileArray);
         // Set the image object to use BinaySgtream object
         // Save the PDF file"/mnt/sdcard/Image2PDF.pdf");
    	}catch(Exception e){
    	// Method Returns the contents of file in a byte array
    	private static byte[] getBytesFromFile(File file) throws IOException {
    InputStream is = new FileInputStream(file);
            // Get the size of the file
    long length = file.length();
    	 * Ensure that file is not loarger than Integer.MAX_VALUE;
    if (length >Integer.MAX_VALUE) {
    System.out.println("File is too large to process");
    return null;
            // Create the byte array to hold the data
    byte[] bytes = new byte[(int)length];
            // Read in the bytes
    int offset = 0;
    intnumRead = 0;
    while ( (offset <bytes.length)
    ( (, offset, bytes.length-offset)) >= 0) ) {
    offset += numRead;
            // Ensure all the bytes have been read in
    if (offset <bytes.length) {
    throw new IOException("Could not completely read file " + file.getName());
    return bytes;
