![]() ![]() But to be honest is does not seem to be very easy to achieve with v5. My initial concert was not to use iText (v7) because we do not have much time to migrate all the projects we have with iText (v5), but I went ahead and tried out with v7. net offering 1000s of FREE fonts to download to help the millions of designers across the globe expressing their creativity with much. Is there any way to do this "out of the box" or I need to overload the method that builds the signature appearance ( like this) and how can I achieve this? multiple widgets visualizing the same signature, PDF viewers may reject it as the legal value of a signature with multiple visualizations is questionable. ![]() If I scale the image to fit the column, it goes to the top of rectangle: IText signature creation code as is can only create a single visual representation per signature, and while it is possible according to the specification to have e.g. ![]() The result is more or less the expected, but there are two problems: the signature information takes over the whole rectangle (this is normal since I do not modify layer 2, and the image in layer 0 is not scaled as it should) c1.SetSimpleColumn(elements, 0, 0, rectangle.Width/2, rectangle.Height, 0, Element.ALIGN_CENTER) // align left c1.SetSimpleColumn(elements, 0, rectangle.Height / 2, rectangle.Width, rectangle.Height, 0, Element.ALIGN_CENTER) // align topĬ1.SetSimpleColumn(elements, rectangle.Width/2, 0, rectangle.Width, rectangle.Height, 0, Element.ALIGN_CENTER) // align right c1.SetSimpleColumn(elements, 0, 0, rectangle.Width, rectangle.Height / 4, 0, Element.ALIGN_CENTER) // align bottom Image img = Image.GetInstance(signatureImage) Įlements.Add(new Chunk(img, 0, 0, true)) In the following code I load the image and put it in a chunk (idea taken from this example) PdfTemplate pdfTemplate = sap.GetLayer(0) ĬolumnText c1 = new ColumnText(pdfTemplate) The signature is being done with the Adobe wizard and using tokens with digital signature installed on the computer. Nevertheless, this is just an initial sketch to set position of the images. In my work, they use a digital signature to validate PDF files that are then delivered to those who request them (who do not belong to the company), so the signature with the signer's data must be seen in the PDF. Here is how the first signature was added. So far I tried working on layer 0 of the signature but I think I doing it wrong because signature details are set in layer 2. The original Hello World example of the document shown in figures 12.6 and 12.7 didnt have a signature field. I am trying to create custom digital signatures using iText (sharp, version 5.5.13) where the user is able to set the image location from a set of four positions (top, bottom, left and right), as shown below: Given the diverse range of modules and add-ons available, iText has the flexibility and potential to address many of the most common customer use cases. ![]()
