I want text in pdf under underline. I am using itext7. How to make it?
Will be thankfull if someone point right direction to this problem. Thanks in advance.
I have a word office document. There are underlines which will be filled manually after printing on paper. Under each underlines there is annotation text which describe what needed to write out.
I try to reproduce this word office document in pdf format using itext7. Everything ok except this annotation texts under underlines. I have googled it, but maybe I have used wrong search keys I have not found solution. Now I am not sure if is it possible to do.
This is fairly easy to implement using text rise setting which is a standard setting in PDF. Below is a brief code sample:
Paragraph p = new Paragraph();
p.add("The beginning of the line ");
p.add(new Text(" (fill in your name) ").setTextRise(-10).setUnderline().setFontSize(8));
p.add(" end of the line");
And here is how the output looks like if you add this paragraph to a document:

I have searched for an answer to this question but perhaps I am searching with the incorrect terminology as I have found nothing so far. Any help would be great!
I would like to extract the positions of text fields, check boxes, radio buttons, list boxes, etc. from an Adobe PDF file. Is there a way to do this? Is there a way to do this with Python?
Thanks for your help!
Does this post help? It runs through extracting text from a pdf and has a line of code commented out which will show the coordinates of text. Finding and extracting specific text from URL PDF files, without downloading or writing (solution)
everyone!
I try to get some underlined text from PDF file by itext, it seems very difficult for me. I've searched the solution for a long time, and I've learned how to get the text's fontfamily, fontsize and text location. However, no underline.
Looking forward to your help!
Thank you!
It might not be possible with itext, but you can achieve this with pdfbox at some extent
look at this: https://stackoverflow.com/a/40039407/4353762
But beware it might not work in some cases, the library needs to know the font and descriptors of the font. if you throw a pdf with unknown type then the descriptor will return null and the code will simply break with NullPointerException.
If you want to handle NullPointerExceptions manually then you might need to look at underlines and strikeThrough methods of
PDFStyledTextStripper.java
I'm developing a new function to "my" program. This function is able to write PDF files by the simple way, making a simple text file with some codes of PDF standard.
I'm trying to understand how it works yet, but my first problem is about how to apply bold on some line of my document.
I've already downloaded the PDF REFERENCES GUIDE, but I've not found nothing about it.
Any idea?
PDF is not like HTML where you can apply formatting tags for emphasis. As you've read in the PDF reference, all that you do in PDF is to setup a graphics environment (colours used, fonts used, etc) and then put text on the page.
If you want to have something show in bold, use a font that is bold. If you want to have something show in italic, use a font that is italic.
Older software used dirty tricks to create "bold-alike" text, but the good (and easy) way to do it is to make sure you select the correct font before you start drawing text.
I have a PDF that contains many underlines and strikethroughs in the text. I would like to be able to convert this PDF to HTML. I have tried many different tools, and all of them will sometimes catch the underlines and strikethroughs as text formatting, and at other times will convert the underlines and strikethroughs to graphics, which is (as far as I can tell) useless to me.
I would really like to know how these programs differentiate between underlines that format text and underlines that are converted to graphics, and how I might be able to access the document and capture everything as text formatting.
I may be taking the wrong approach with this, and am open to any possible solutions, I think I just need to be pointed in the right direction.
Thank you in advance for any assistance.
There are no underlines and strikethroughs in PDF, there are just lines being drawn on top of text.
PDF tools that detect underlines and strikethroughs will usually look for a line drawing that is close enough to the text, or some other similar heuristics, then add the corresponding style to the text output when converting into another format. However this kind of approach will never work for 100% of the cases.
So, I have a local .rdlc file with some text formatted using strikethrough formatting. My issue is quite simple to explain, but I do not know if it is just a limitation of PDF, or a bug with the .rdlc exporting to PDF.
When I write this code:
var localReport = new LocalReport();
...
byte[] pdf = localReport.Render("PDF");
System.IO.File.WriteAllBytes("MyReport.pdf", pdf);
None of the strike-through formatted text transfers over the the .pdf file properly.
If instead, I export to Word using .Render("Word"), the strikethrough does work on the .doc format. So, I know it isn't a problem with the .rdlc report itself.
Has anyone encountered this? Any solutions or workarounds?
I found this: http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/b35ca474-046d-4a38-a765-6c38c3d33105/
which suggests that missing strikethrough in PDFs was a known limitation. (But as mentioned in comments to the question, I couldn't reproduce with 2008r2.)
The two workarounds given there look painful.
(A) finding a font which itself as the strikethrough built into each
glyph/character. (B) trying to mimic a strikethrough using a line
report item. Note that for (B) overlapping items are supported only in
PDF, Print & TIFF formats.
I suppose if it were mine, I would play around with option B if the text is a small amount. Also, it may be worth test some of the html passthrough enabled when a placeholder is set to render as HTML. Maybe using a strikethrough style there would work?
While exporting RDLC report on word, I faced this issue. So while fetching data I replaced style for Strike formatting with strike tag from HTML and it worked.
