PNG Merge: MVC

As a continuation of this forum post (which seems to be archived):

https://www.telerik.com/forums/png-merge

All the given examples show how merging two images can be done in JavaScript. I need this to happen in ASP.NET Core MVC 5.0.

I assume this will look something like how we marge PDF files. I merge two PDF files like this:

            MemoryStream newStream = new MemoryStream();
            using (PdfStreamWriter fileWriter = new PdfStreamWriter(newStream, true))
            {
                using (PdfFileSource fileSource = new PdfFileSource(primaryStream))
                {
                    foreach (PdfPageSource pageSource in fileSource.Pages)
                    {
                        fileWriter.WritePage(pageSource);
                    }
                }

                using (PdfFileSource fileSource = new PdfFileSource(appendStream))
                {
                    foreach (PdfPageSource pageSource in fileSource.Pages)
                    {
                        fileWriter.WritePage(pageSource);
                    }
                }
            }

OutOfMemoryException convering to pdf

I am attaching a simple sample app to show the problem. I have an app that makes a catalog of images. somewhere between 4000 and 4500 images, the docx is created, but I get an OutOfMemoryException when creating the pdf. Also if the pdf is created, it is larger than the docx. The docx was around 483MB.

in the app load an image (one is provided), select number of images from spineditor and hit create catalog button and wait for the process to complete.

1. why is pdf larger than docx

2. What to do about the OutofMemoryException.

How to determine a color for the background

I'm working with SpreadStreamProcessing. I want to set the background color for each of the cells in a specific row.

Created an excel mockup and like the "Blue, Accent 5, Lighter 40%". How can I find the RGB code for this?

Also is there somewhere one can find a color converter to RGB or visa versa?

Wish to download trial version of Telerik Document Processing but can't see it in the Progress Trial Installer

When I am on the Telerik site I request a trial of Document Processing.

It provides the Progress Trial Installer as the download.

Is the set of Products to Install, I cannot find Telerik Document Processing listed. All the products listed are either UI tools or reporting tools.

Confused about how to obtain a trial install of the Document processing libraries...

EDIT: Ok I found in the docs.

The Telerik Document Processing libraries are available in .NET Standard and .NET Core compatible versions. You can download the assemblies of these libraries from the UI for Xamarin, UI for ASP.NET Core and UI for Blazor suites, respectively.

Server side editing an existing pdf

I've a .NET core web-api project and I need to edit the existing pdf (like adding an image/ text) without using UI. The pdf files are stored in Azure Cloud which I can access through URI.

So, is that doable? Would appreciate if you could point me to the right Telerik libraries and any examples would be great.

UI for Blazor: Preview RadFixedDocument or PDF / alternative export to and view Image

I'm using Telerik UI for Blazor and have to create some PDFs (via RadFixedDocument and PdfFormatProvider). This works fine so far.

But I also have to display a preview of the Document on my blazor-generated website (server side, not WebAssembly). It doesn't matter if this is a preview of the FixedDocument or of the generated PDF.

Does a control for "Telerik UI for Blazor" exist which can display the RadFixedDocument or the PDF? Or is there a possibility to export the RadFixedDocument or the PDF to an image and I can display this image? Or is there another way for making the created Document visible for preview?

TIA

Rudi
