React Native PDF - Complete Input - react-native

In my app I am able to sign some pdf.
Actually, after that the customer signed the document, we tap on the pdf where we wants to place the signature.
But we have to change this, because when we have a 30 pages pdf and the signature is at the end, we have to scroll so much.
So, we decided to add an input "signature" in the pdf, so the app could find this input and fill it with the signature, with the x and y position.
But how can I fill a PDF input with my image ?

Text changed to graphics, still selectable in PDF?

I have this PDF ebook with selectable text - the handwriting - but there is no such font embedded and the letters are all different, so it's not actually a font. How is this possible?
I've worked with CorelDraw and Adobe Acrobat, but I can't understand how this works.
The left side of the picture shows the document properties, the right side shows a page of the PDF file and I selected the last 3 rows. I can copy and paste that to a text file, no problem. How was this achieved?
There are a few possibilities but the most likely is the text is being converted to outlines/paths or vectors. Some software such as Adobe InDesign and other print design apps allow you to 'flatten' a font based text into vector or paths, meaning the original font isn't required to be embedded or installed on the system. The original text data is however still present and able to be copied into a text field or word processor.

Create template for PDF creation in Cocoa / Objective C

I am coding a Mac application. I want to give the user the opportunity to create a template for PDF creation. The PDF should be created from different NSTextFields where the users types in. So, the PDF creation should be dynamic. For example for an invoice. The format stays while the information on the PDF changes.
I use a NSTextView with a ruler which is always shown. Now I want to write for example <TextField1> in some point of the Sheet and where this TextField1 is, the input from TextField1 should be. I thought about getting the position of TextField1 and using it in the PDF creating process. But I am still not sure if its the right way. The PDF should always be for A4 format. Is it even possible to set the PDF View (on the screen) to an A4 view, so the user can see how the PDF will look in a printed version ?
The ruler is shown by using [textView setRulerVisible:YES];

How to read the value of fields in signed PDF using PDF Box API

Once after completion of digital signature for PDF using DocuSign, How to read value of the fields in PDF using field ID/Name (using PDF Box API)? I am not able get the field ids of Digitally Signed PDF.
The sample PDF showed that the fields in PDF are not PDF form fields after all, neither Acrofornm nor XFA, they merely are texts with some lines around them. (They may once have been PDF form fields which were flattened, or they may never have been PDF form fields to start with.)
Thus, your only option left is text extraction. PDFBox has a quite elaborate text extraction engine. Have a look at PDFTextStripper. You can try and use this class as is, looking in the extracted string for the field labels and extract the following text until the end-of-line; or if you have the time, you can try to make use of the internal PDF structure where the field contents are in a separate Xobject.

PDF forms in Apache FOP generated PDF

I am using FOP to generate the PDF from XSL:FO and iText to apply the digital signature and signed date field in the PDF.
Problem is i am using co ordinates to apply the signature and date in the generated PDF.
The PDF are large, dynamic and changing always based on content. therefore the signature and date fields were not positioned Properly by the co-ordinates specified.
I googled to find solution for a long days. But i didnt get any solutions.
Can u please any one suggest me to create the PDF form fields in the PDF using FOP?
Then i can apply signature and date fields by using iText.
Please tell me any other technology to try to solve this problem?
The problem is that FOP doesn't create signature fields whereas iText needs a page number and coordinates (either defined by you or by a signature field).
Where do you want the signature to be placed?
Is it always on the first page? Always on the last page?
Can you put some unique text at the location where you want the document to be signed?
I'm asking this because you could put words like SIGN HERE on the last page, and then use TextRenderInfo to retrieve the coordinates of those words. See http://itextpdf.com/examples/iia.php?id=275 in combination with http://itextpdf.com/examples/iia.php?id=282
The TextRenderInfo class has methods such as getBaseLine(), getDescentLine(),... who give you LineSegment object which reveal the coordinates of each snippet of text in your PDF.
There are plenty of caveats: FOP could cut the words SIGN HERE in different snippets, such as "SIG", "N", "HE", "RE" which would make it difficult to recognize the unique string, but it's worth investigating.
