I am using iText 2.1.7
I write a pdf document for which the page size and contant can differ each time. What i want to achieve is a table at the very last page and at the bottom of that page. I am aware of the method 'writeSelectedRows', but with this it could happen that i overwrite text on the page, because i dont know if there is space for my table.
So in conclusion:
If i have reached the last page i want to add my table at the bottom of the page. But if the table does not fit, i want a new page and on this page i want to add the table at the bottom.
I could not find a solution so far.
Use this http://developers.itextpdf.com/de/node/1910 to calculate the height of a table and then check the available space on a page with PdfWriter.GetVerticalPostition(). You might want to consider your Document.BottomMargin or some other offset in your space calculation. (v4.1.6)
Check out this link:
http://developers.itextpdf.com/content/best-itext-questions-stackoverview/general-questions-about-itext/itext7-how-find-out-current-cursor-position-page
I suppose that once you know the current cursor position on this page, you can write a simple if-statement to add a new page, or not.
Kind regards,

I want to ask a question which is related to apache poi and generated file printing. What I am doing is I am opening a .docx file, inserting some data and saving and printing it.
I am having a file with only 1 table which is something like:
document table
Now, if there are 'n' items, I am generating n-1 rows which copies the format of row 3.
First item is inserted in row 3, if there's another item I am adding a row in the table and saving it likewise I am creating the rows.
Now I want to make this table length = page length. For this I am counting exactly how many rows this page can incorporate and based on that I am inserting empty lines without inside top and bottom border.
The file does not have any header/ footer or any other details as of now.
While I am creating the file I am shown the file which is coming in print preview of covering the whole page of size A4.
But this document is printed only on 80% of paper. I am having 0.3 cm margins but in print the whole page is not printed.
This does not seem to be the printer issue because if other software like Google Chrome are used then it prints the complete page.
So I want to ask that how can I solve this? I tried to search about this but till now I couldn't solve it. I think of this as an issue that whenever I am using XWPFDocument, its margins and all are changed set to default size. I don't know whether this is the issue or something other is, do I need to write some commands to preserve the margins and all or there's something that I need to do.
How can I solve this thing?
Thank you.
I am using current BIRT version that is 4.5. I have two master pages in my report. I have huge data to display on a report so i have set some data to display on one master page and the remaining on another master page due to some reason. The problem is when there is no data to display on one of the master page it is rendering a blank page with header and footer of that master page which i want to avoid. In my pdf report how can i avoid this blank page?
Hi, all are pointing to hide tables or other components but my requirement here is, i need to hide the page itself. I dont think there is visibility option for page. even if it is there it is not so useful. Kindly understand that i dont want to display the page itself not only the components in it.so can i expect any help now?
I guess you added the tables directly on the masterpage?
That's not how it works. BIRT will render the (master)page and maybe hide the elements on them (for example a table that has no data. You can do this by setting the visibility property). The problem with this approach is that the Masterpage cannot be 'unrenderred'.
The proper way to fix this, is to add each element on the normal layout. In the properties for each table, grid, etc. you can set the pagebreak properties. Here you can select the Masterpage you want to use. If an element does not need to be rendered (by visibility settings), it wont trigger a 'blank' masterpage.
Hope that helps.
Is there a way to specify different margins for my first and last pages in iText?
I have a large header to be placed in first page and a large footer to be present in the last page.
The trouble is when I position the footer absolutely the content of the page might overlap it because of the absolute positioning.
yes.
before creating last page, set margins and then call newpage() method of Document object.
I have a requirement to insert Content into the middle of the page in a PDF.
The Content may be a Dynamic Table or an Image.
My Concept was to first split the PDF into 2 parts, then get the new Content that is to be added and append by replacing a place holder field.
the Splitting is called Tiling as per IText and here is an example for the same.
http://itextpdf.com/examples/iia.php?id=116
The Code above has 2 drawbacks:
1. It splits the page into 16 parts. but that is part of the example. Still i cant figure out a way to split the file into 2 parts only.
2. secondly the split page is converted to a complete page thus disturbing its proportions.
The Rearranging code is the another problem.
The remaining Content should be re-ordered in append mode. but till yet i have only found codes to add complete new pages rather than just the content.
I have found a code that appends the PDF content by replacing a placeholder:
float[] fieldPosition= pdfTemplate.getAcroFields().getFieldPositions("tableField");
PdfPTable table = buildTable();
PdfContentByte cb = stamper.getOverContent(1);
table.writeSelectedRows(0, -1, fieldPosition[1],fieldPosition[4],cb);
Please help me to solve this requirement.
PDF is a presentation format, not an edition format. In other words, it is not designed to allow content insertion, with the original content reflowing gracefully. As a consequence, no tool (at least, none that I know of, and surely not iText) will enable you to achieve what you were given as a requirement.
My advice :
refuse the assignment since it's not feasible, or
get your hands on the original document, insert the desired extra content, and then convert to PDF.
How can i be ensured that every detail section won't be separated in diffenent pages?
If two detail sections aren't able to fit into one page without second devision into two parts, then they must be set into two pages. I don't want the second detail section been divided.
thank you
Are you using iReport? If so, simply click the detail node in the outline window (that tree structure on the left of the screen) to bring up the properties for that band. The properties window will appear on the right side of the screen. Where it says Split Type, select "Prevent" from the drop down menu. If you are coding your report in jrxml, when you get to the <detail> tag, in its first child tag, <band> set the attribute splitType="Prevent".
I am not sure that this is a better way of doing it but you can do it by checking the sum of the sizes divisions being greater than or less than the total size total size of page. If it is less than the size of the page you don't need to do anything but if it is greater you can simply take out the last division and put it on the other page. There would be some way of pagination in JasperReport, try googling it. Hope it works for you.
