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.

I did some research and find out that you can create PDF with images or texts or by exporting the screenshot, but I want to create much more like in the image below:
So what I want to achieve is to have a good resolution for PDF to print the PDF as a book after this. The physical book has a lot of pages and my client wants to create the virtual one.
So, I have the design (as you can see in the image), but I still need to create some text fields, signature and some logic in the widget.
How can I export after that to a one page PDF for every widget?
Screenshot won't be enough because I think it doesn't have a good quality and ofc the text and everything else won't be suited in the phone screen.
I am thinking to use the basic design and to add manually by code the texts, but I don't know how to export this to a PDF after that.
Of Course! The pdf package is a great start.
I am working on a flutter app which generates PDF files in flutter using pdf library.I need to create a pdf file which has a table of contents. They should be linked with the actual content and should navigate to their respective pages when clicked on it. I couldn't find any documentation online for doing this using the pdf library. The PDF is going to be written to a file so PDF Viewers in flutter are not useful for me either. Can someone please help me out
can we use html code with dart like <a tag or something for internal navigation in PDF?
You can use Anchor and Link widgets from pdf/widgets.dart for internal navigation inside the generated PDF.
Just create an Anchor on the page to which you want to navigate to. You need to provide a name parameter for it and it should be unique.
Anchor(name:'my_anchor', child: any_child_widget);
You can now refer to that anchor from another page using Link widget.
Link(destination:'my_anchor',child: any_child_widget);
You can enclose any child within the Anchor and Link widget.
In my Flutter app, I want to be able to create some kind of certificate of completion. The layout will be always the same, but picture and text in it should change. This certificate should be created in a jpg format, so I can share it with other apps.
Does anyone have an idea how this could be accomplished?
The only way I can imagine is that I create a Screen template where I put in text and picture, then let the phone take a screenshot and save that screenshot automatically. But this might lead to unwanted content in the picture and different image sizes. I have searched for Widgets/ ways to create an image in Flutter but could not find anything.
You will need to create a widget with constructors (Image and text).
Then use a flutter package called screenshot to capture the parent widget as image and save it to the users phone.

Can anyone provide manuals for this yii2 plugin use?
I have installed it but have not been able to find the options it accepts, for example: Right after an image is uploaded, the thumbnail displayed is in full size (bigger than the page width). How to resize that?
Thank you.
sample 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.
