I have a scanned PDF that has multiple areas of text handwritten text. I want to see if there's a way in itext to extrapolate coordinates on the page to be inserted into separate Container or viewers. Such as did this person sign the document? show the last 2 inches of the page starting 3 inches from the left.

Bear in mind that the iText co-ordinate system starts bottom left, like a graph and 72dpi

Two way to do it spring to mind

A: Copy the file and just make the crop box to the size of what you want left to display, leaves the whole file there just not visible

B: Render the file to an image and then use a java awt transformation to just get the part you want. (This could in part be done in FM12 with the Get (Thumbnail) function)

The first one is really easy

import com.itextpdf.text.pdf.PdfDictionary

import com.itextpdf.text.pdf.PdfName

import com.itextpdf.text.pdf.PdfReader

import com.itextpdf.text.pdf.PdfRectangle

import com.itextpdf.text.pdf.PdfStamper



reader = new PdfReader(src)



// make this 'lower left' 3in along, 0 up TO 'upper right' pageWidth along 2in up

PdfRectangle rect = new PdfRectangle(216, 0, reader.getPageSize(1).getWidth(), 144)



// for ALL pages use this

n = reader.getNumberOfPages()

for (i in 1..<n) {

pageDict = reader.getPageN(i)

pageDict.put(PdfName.CROPBOX, rect)

}

// or for just ONE known page

//pageDict = reader.getPageN(1)

//pageDict.put(PdfName.CROPBOX, rect



stamper = new PdfStamper(reader, new FileOutputStream(dest))

stamper.close()
