Add image to acrofield in iText?

Question

I\'m trying to fill PDF using acrofields, I\'m able to add string data perfectly, but having issues in adding images to acrofields. This is my code for adding string data..

Answer 1

You can try add this with your code for adding Image

PdfContentByte content = stamper.getOverContent(reader.getNumberOfPages());
Image image = Image.getInstance(new URL("E:/signature/signature.png"));
image.setAbsolutePosition(450,650);
image.scaleAbsolute(200,200);
content.addImage(image);
reader.close();
return output.toByteArray();

Answer 2

The "official" way to do this, is to have a Button field as placeholder for the image, and to replace the "icon" of the button as described in my book:

PushbuttonField ad = form.getNewPushbuttonFromField(imageFieldName);
ad.setLayout(PushbuttonField.LAYOUT_ICON_ONLY);
ad.setProportionalIcon(true);
ad.setImage(Image.getInstance("E:/signature/signature.png"));
form.replacePushbuttonField("advertisement", ad.getField());

See ReplaceIcon.java for the full code sample.

The following solution worked:

public static void addImage(PdfStamper stamper,AcroFields form,String field,String fieldValue){
    try{
        System.out.println("Field "+field);
    java.util.List<AcroFields.FieldPosition> photograph = form.getFieldPositions(field);
    if(photograph!=null && photograph.size()>0){
    Rectangle rect= photograph.get(0).position;
    //if(StringUtils.isNotBlank(fieldValue)){
    Image img = Image.getInstance(fieldValue);
    img.scaleToFit(rect.getWidth(), rect.getHeight());
    img.setBorder(2);
    img.setAbsolutePosition(
    photograph.get(0).position.getLeft() + (rect.getWidth() - img.getScaledWidth() )
    , photograph.get(0).position.getTop() - (rect.getHeight()));
    PdfContentByte cb = stamper.getOverContent((int)photograph.get(0).page);
    cb.addImage(img);
    //}
    }
    }catch(Exception e){
        e.printStackTrace();
    }
    }

calling the above method:

addImage(stamper, form, "CustomerSign", "E:/signature/signature.png");

where CustomerSign is AcroField
