I have a requirement where I need to generate a PDF document in Java using iText.
The ask is to use a PDF template, and inject the data values in a user designed PDF template to produce the desired output PDF.
The documentation on the iText site is not clear/or I didnt search them completely, so asking for support or article regarding this,
Our use case is to generate a table from a PDF template, where the number of rows is determined by the data (i.e. in here JSON). I should be able to dynamically scale the number of rows in a PDF template based on the data size.
Is this possible?
I was referring to this article:
https://github.com/koendehaen/itext_summit_pdf_templates
In the above GITHUB example, the rows were prepopulated in the PDF template, I want something like the below screenshot, similar to how Handlebars provide, where a for loop on a hbs template, and I can inject data.
Example:
Suppose I have a table like below
But here the row count is dynamic based on data set, how to scale the table dynamically
Note:
I cant create the template in HTML, like handlebars, etc...
Since business people with little to no technical background will be the users who will be generating the PDF template.
You can search the all key values of your JSON, and before insert this value in PdFTable. In my case, i get the lastCellNum:
Row row = rowIterator.next();
PdfPTable table = new PdfPTable(row.getLastCellNum());
Iterator<Cell> cellRow = row.iterator();
while(cellRow.hasNext()) {
Cell cell = cellRow.next();
I am trying to strip the text of a PDF document but the columns are out of order. I'm getting the last column as the first.
How I can reorder it? See document here.
I have to extract whole pdf content using iText. But i couldn't read the contents in table.Because table is not a selectable part in Pdf. How can I make the table content as selectable in order to extract the table content?
I am using pdfptable to print. Cell, when table is reaching at end of page and any cell which is carrying more data and with same cell continuation is not coming next page , actually it is truncating data of cell . I am using single table in my code to print data
Does it possible to solve this issue?
How can I repeat the headings of a PdfPTable in all the pages if the length of the table exceeds one page?
Look at setHeaderRows(int headerRows) of PdfPTable. Rows defined there as a header should persist on new pages.
table.setHeaderRows(1)
for the first row as a header.
See the API.
