I'm currently trying to generate PDF with PDFBox for some manual cover and I was wondering if it was possible to take a precise zone of text in my PDF and move it (to the left) depending on my manuel thickness (which will be determined by the number of pages my manual will have)
I manage to create my PDF just fine, but I did not find a way to get only a block of text.
Is it possible to do so with PDFBox?
Note : I tried to search on the web and on other questions, but none of them were useful.
Thanks
Wrap saveGraphicsState() and restoreGraphicsState() around that block. Within that, use moveTextPositionByAmount() (after beginText() !) or setTextTranslation() or (more general) concatenate2CTM(1, 0, 0, 1, tx, ty) to move the position.
Like i said in a comment, we decided to create a new PDF with the informations needed instead of trying to edit an existing one.
We tried to edit the PDF but in vein and when we decided to start from scratch, it was way more easier to do so.
Thanks to the people who tried to help me !

I know there are many suggestions how to resolve problems with edition existing PDF, but among all of those, I couldn't find a solution for my problem.
I need to add information about file acceptance ("Document accepted by Tom Smith, 2020-01-01" - possible multiple acceptations) to the last page of the PDF. I need to determine if page is filled or is there enough space for my text.
I wanted to find position (y) of the last element on the last page of the pdf to check it against page size. If the page is full I'm going to add a new page and then add new text.
I have no idea how to resolve this. I tried looking for answers with iText and PDFBOX, but there are no satisfying resolutions.
Raster Image based approach:
Render the last page of the pdf to a bitmap image with any library you are comfortable with (Ghostscript?). 72 dpi should be enough for your purpose.
Then you can use any image processing library like openCV and check rectangular areas starting from the bottom up, if pixel exist. openCV is very fast with the CountNonZero() function.
You can also find any large white zone that is anywhere in the Image, not just at the bottom. This link could be your starting point.

I need to replace a variable ${var} with an image in a pptx slide. Also, this image has to be in a specific size (idk which yet). I think inserting the image in a given position in the slide would do the same for me, but the documentation for pptx4j (which gives an example of how to insert a picture in a slide) couldn't really help me.
Many thanks in advance! :-)
It is relatively hard to program such image manipulation for PowerPoint files.
Maybe SlideMight would be a suitable solution for your use case:
This utiltiy lets you merge data with PowerPoint templates; both text and images, in slides and tables. The usage is in principle similar to mail merge, with some more advanced stuff.

I'm looking to automate filling out a pdf contract by putting variable text in predefined locations(such as a date or dollar value). I've been trying to wrap my head around iText as a solution but am having trouble actually stamping text onto a pdf. I would really appreciate an example snipped that simply stamps a piece of text on a specific (x,y) coordinate of a pdf file.
If there is a better solution than iText to my problem I would also love to hear other possible solutions.
I have a PDF page that Logo, 4 address lines and content. I want to realign the 4 address line to the left about 3 - 4 inches, but keep everything else the same. Is it possible to do this using iText java version?
As far as I know, thats going to be a hard one. Thats not a typical iText-mission. Good for creating PDFs from scratch, not so good at reading or editing. (You can easily add content though).
I'm working on application in Java that will maintain database of song lyrics in plain text and print out some songbooks/chordbooks(that is create PDF file from selected songs). I was planing that the Java application will generate source code for pdflatex and after compiling this source user will get PDF file.
Lately I've run into a lot of problems because of latex limitation: fixed memory size (some pictures will also be drawn to PDF) - error when exceeded, no way to query end of line or and of page dynamically, it's very hard to override latex placement algorithm in a complex way,... see also some my other questions regarding latex. I come to conclusion that latex is not good option for automated PDF generation.
So I need replacement. I need to be able to typeset:
Chords over lyrics when the lyrics are in variable char width so I need to be able to measure text width
Chord diagrams that means I'll have to draw quite complex pictures
Each song on separate double page
Different fonts etc.
Thanks for all answers
Here are some PDF open source APIs

This has been asked many time, You might want to look at this post
IText is a free library which offers lots of capabilities for creating PDFs programmatically.
Rather than try to manage/calculate the complexities of the desired layout, you could try Docmosis. It will let you layout a document as a template using doc or odt formats. This means if you could make a doc or odt look like you want, you can turn it into a template and get Docmosis to render it as a PDF. Text and images can be placed inside or outside tables which makes layout fairly easy to manage.
ConTeXt is another TeX system, but it is easier to control the layout than with LaTeX. For drawing you could use PGF/TikZ or MetaPost. Support for both is available in ConTeXt. With ConTeXt's built in Lua scripting you could draw the chords automatically, assuming you have them stored in some sort of data structure.
why not just use lilypond with latex? it's meant for typesetting music.
