Print the substring in small font size in pdf

I using the below code to print a string in pdf which give me an out put of the same sized string i want to make the last two string in different font size. how can i do this ?

PdfContentByte cb = writer.getDirectContent();

    String stl = "", stl1 = (String) request.getParameter("x0");//                        (String)val.get(0);
        int ln = stl1.length();
        String new1 ="" ;
        if (ln > 1)
        {
            for (int ii = 0; ii < ln - 2; ii++)
                stl = stl + stl1.charAt(ii);
            stl = stl + " . ";
            stl1 = stl1.substring(ln - 2, ln);
            new1 = stl + stl1;
            //stl1 = stl + stl1;

        }
        cb.setFontAndSize(bf, 18); 
        cb.setTextRenderingMode(2);
        //cb.showTextAligned(PdfContentByte.ALIGN_LEFT, stl1, 20 + x, 663 + y, 0);
        cb.showTextAligned(PdfContentByte.ALIGN_LEFT, new1, 20 + x, 663 + y, 0);

Desired Output :

Solution

  • The best way to do this is to print a separate string after the first one that contains the last 2 digits.

    Code example:

    1) Replace String new1 ="" ; with this:

    String textLarge ="" ;
String textSmall ="" ;

    2) Replace new1 = stl + stl1; with the following:

    textLarge = stl;
textSmall = stl1;

    3) Change some code to print the large and small text separately

    cb.setFontAndSize(bf, 18);        
cb.showTextAligned(PdfContentByte.ALIGN_LEFT, textLarge, 20 + x, 663 + y, 0);
cb.setFontAndSize(bf, 14);        
cb.showTextAligned(PdfContentByte.ALIGN_LEFT, textSmall, 20 + ? + x, 663 + y, 0);

    Replace the "?" in the line above with the printed width of large text. It looks like you are using itext, so you can use either: BaseFont.getWidthPoint(String text, float fontSize) to get the width of the string in pt. Or put the string in a Chunk and do chunk.getWidthPoint()
