PDFGenerator | A simple generator of PDF written in Swift | iOS library

I am having a very weird problem that I cannot figure out. I am trying to add a loading dialog box to a page that generates a pdf. I coded the web page in a separate project, and the dialog box worked perfectly. But when I included the extremely basic jquery-ui code into my existing website project, it doesn't work. Specifically, the popup doesn't go away when the PDF loads into the iframe. Basically the .load(function()) event isn't triggering.

But the event triggers just fine in my separate project. I generate the exact same pdf using the exact same data and code, and it works fine. But when put into my main project, the load event doesn't trigger.

Here is my code. The company I work for still uses webforms so ...

I am saving images into pdf document

let suppose I have 3 images and add them to the document it should show 3 pages. but what's happing is this I am getting 4 pages with the first page empty.I am using TPPDF pod for this

TPPDF Environment TPPDF version: 2.3.5 Xcode version: 13.0 Swift version: 4 or above

Demo Code / Project

I am currently writing an addition to a website that I made for work. It generates a PDF from an HTML template and then serves it to the browser so that it can be printed off.

I created a small test that works perfectly. The problem I am running into is when I coded a more complete test, nothing happens when I click the generate button. In the first page when the page loads the PDF is created and shows in the browser. On the second page I get nothing, and no error message which makes troubleshooting this difficult. The code is almost identical between the two pages, so I am really confused as to what is happening.

I will post both versions of my code. Hopefully you guys can figure out what is happening.

I'm looking for some inspiration or the best practice to eliminate a bug that is very strange...

In the code below, a little below the class PDFGenerator, I'm declaring a public variable named strOutPutPath, because I use its value in several functions and subs of the complete code... below it's just a snippet to illustrate what I'm dealing with...

During a loop to generate files, randomly, the value of strOutPutPath becomes empty. It's random, it happens arbitrarily with any number in the range covered by the For loop, but usually above 260 and after the loop is generating PDF files for a couple of hours...

Because strOutPutPath becomes empty (And I have no idea why), when an iteration (Usually above 260) attempts to start the process and passes an empty strOutPutPath as the value of the argument /outputdir:, the software hangs because PDFGenerator.exe receives an empty argument for /outputdir: and thus never exits, making the main application to eternally wait for its execution.

My 1st idea was to declare strOutPutPath as a public CONST variable in the class, however this is not possible because I have to grab the value of strOutPutPath from a registry key in the Main sub.

Also, I need to treat the contents of strOutPutPath within the scope of Main sub (Not shown in the code below), so that's why I grab it from within Main.

I may be dealing with a .NET bug or simply using a poor practice that is causing .NET to empty strOutPutPath once the application is working for a few hours. I have no idea about the root cause of my problem.

But I'd like to know what would be possible solutions for making strOutPutPath to act like a CONST variable once it is populated and treated within the Main sub. After that it is not supposed to change anymore and will be called by half dozen functions.

Many thanks!

Fair warning: This post is a bit of an essay-sized question... So let me say my thanks beforehand to whoever goes through it and tries to answer it.

Context:
I have been trying the only 2 free-commercial-use open-source html to pdf converting libraries I could find.

PDFSharp unfortunately outputs a pdf with a completely messy style layout that doesn't respect the formatting of the input HTML and sometimes doesn't output images properly. (How it should've look vs how it looks with PDF#)
TuesPechkin (wkhtmltopdf c# wrapper library) on the other hand does it all right except for only outputting these odd "image containers" (a hollow outline of where the image supposedly should be).

I declare the IConverter object upon calling my class' constructor like so:
converter = new ThreadSafeConverter( new RemotingToolset( new Win64EmbeddedDeployment( new TempFolderDeployment())));

Then I have the following method where you can find the GlobalSettings and ObjectSettings I'm currently using for the conversion.

This is the error I am getting: Microsoft.WindowsAzure.Storage.StorageException: 'The remote server returned an error: (404) Not Found.

On the following code:

First method for PDF Generation using PDFSharp:

I'm using TheArtOfDev's HtmlRenderer.PdfSharp to convert an HTML string to PDF in a ASP.NET web application. The HTML contains Japanese characters. The Japanese symbols are converted to ☐ ascii characters.

How can I enable UTF-8 or use a custom Japanese font? I tried the following without results:

• Adding to the HTML string.
• Adding to the HTML string and then settings the font style on the element with Japanese text.
• Try a CSS file with @font-face and calling TheArtOfDev.HtmlRenderer.PdfSharp.PdfGenerator.ParseStyleSheet

I'm generating PDF by using https://pdfgeneratorapi.com/.

Now I can show data one by one using this code.Can any one give me suggestion how can show all data with loop or any other way? This below photos showing my template from pdfgenerator .

This is the code I'm using to generate PDF

I want to show pictures in PDF with HtmlRenderer.PdfSharp. I am using this example. https://github.com/ArthurHub/HTML-Renderer

I can show this link in PDF. https://helpx.adobe.com/content/dam/help/en/stock/how-to/visual-reverse-image-search/jcr_content/main-pars/image/visual-reverse-image-search-v2_intro.jpg

But I can't show this link in PDF. https://images.data.gov.sg/api/traffic-images/2016/02/96128cfd-ab9a-4959-972e-a5e74bb149a9.jpg

Because when you enter this link, the picture is downloaded automatically and is not displayed in the browser.

This code generates the PDF.
