I am using itext to generate pdf files with images and with some description for that image.
I want to print one image and description of that image in one page.
For next image want to print in next page.By using itext how i can move to next page ?
Lot of way to do that. Simply what i understand from your question how to generate a new page in a Pdf Document. Algo will be like this
for each image{
/*manipulation logic for image and text goes here */
document.newPage();
}
Do a checking for last time loop is iterated otherwise it will create additional blank page.

I am trying to get the position of Paragraph in pdf file.
Right now I get it at pdf generation time, by getting the current position before/after adding the paragraph to the document. And then I use that position to edit.
Is there easy way to find location of paragraphs, after the pdf is generated?
Should I stop using paragraphs and position, and switch to template with AcroForms for filling in data programatically?
Everything works, but It feels like ive selected the wrong approach.
Thank you in advance.
I upload the pdf file from storage.
I'm trying to place the signature image at the bottom of every single page of pdf file and save as new pdf file using flutter.
I don't know how to do that? I tried my sample but I didn't find the solution I wanted. Please suggest me any flutter plugins or packages.
The idea is very simple: it consists of reading the pdf file as images
(one image per page), and then create a pdf, having as background one
of the retrieved images.

Imagine a pdf with text and a application that test images over the text.
In every test pdf is saved and the next test using same pdf.
The first time you add image under text you can see the results, next time you will try you add image under is not appear because first image cover it.
So...exists something GetBetween or can i choose the layer that i want?
If i use GetUnderContent only first image appears and all others are hide.
If i use GetOverContent then the text is covered by image.
My Desktop App is creating a single page pdf with itextsharp library.There are 40 Passport size photos with names under it on a single page.
I need to flatten this pdf page (with 40 photos) as one Image while creating the pdf,currently there are 40 individual photos on the pdf page.I presume it would create around 80 layers by default which would take a very high time on ripping this file for printing on a press.
I dont want to make all the 40 images as one jpeg externally using GDI+ and then lay it in pdf.
I have seen many options using stamper and reading the created pdf file to flatten.Is there a way while creating the pdf i can create a flattened file.
Your understanding of flattening a PDF is completely wrong. The concept of flattening a PDF means: removing all interactivity. For instance: you have a PDF file with form fields. The content of these form fields can be changed in Adobe Reader. When you flatten such a form, you take away the form fields and replace the field content by actual content of the page. The result is a flat PDF in the sense that people can no longer change the content of the fields.
You presume that having multiple pictures on a single page in a PDF means that there are multiple layers in that PDF. Your understanding of layers in a PDF is completely wrong. Layers is a word that is used in many different contexts. For instance, when working with optional content groups (OCG), people often refer to layers.
The concept of layers as you may know it from Photoshop doesn't really exist in PDF. Content is added in a stream. Whatever content is added first, can be covered by content that comes after. You want to pro-process the content by removing all the content that isn't visible in the hope that the PDF will be printed faster. You want to achieve that by replacing many different image objects by one image.
Your assumption that this can be done with iText is wrong. iText doesn't convert PDF to an image. This is outside the scope of what iText is written for.
If you want to add X images as 1 single image using iText, then you have to process the X images into 1 single image before you add the images to the PDF. You need image manipulation software, because iText won't do what you're asking for.
I have a requirement to add few lines at the top of an existing PDF.
I have done this using a PdfReader and a PdfStamper.
In order to have more space in the page header area, i need to move down the current contents by 1 or 2 lines.
Below is from the forum. but it doesn't solve the issue.
How to insert content in the middle of a page in a PDF using IText
Any suggestions?
-i can not upload the pdf or the image of the pdf because am a new user
Do I interpret your question correctly if I assume that you really want to move down everything on the page and add some lines above?
You can do that by changing the media box (and crop box and what other boxes might be explicitly defined for your page) and then add the few lines on top the same way you already do it now.
You can access those boxes in the respective page dictionary which you can retrieve via the PdfReader. Look up the PDF specification for details on those boxes.
Or do I interpret you incorrectly and you only want to move down some text while keeping existing headers and footers in place? In that case Alexis' answer to the other question you refer to still holds.
