KG, https://www.smartinmedia.com) and have to pay salaries to our developers. As we also believe in free software, we give away this under the __MIT license__ and you can do whatever you want with it. Other than with commercial libraries, you are not bound to making continuous paments, etc. So, if you saved money and time by using this library, please donate to us via Paypal! 10 | 11 | ## Background/Why? 12 | I was working on a medical project (https://www.easyradiology.net) and wanted that users receive a dynamically created PDF document via e-mail. Can't be too difficult, I thought. There'll be some library to do that. I discovered that in fact, there is PDF Sharp, an open source library. However, I found out that you have to "code" each line of the PDF yourself. What happens, if your sales department or user support wants to change just one line here or update a logo there in the document? Then, you have to go back to your code, change it, talk again to the sales dept or user support, if they are happy, etc until you can create a new release. This is super tedious. So I thought, would be great, if the sales department / user support can just create a simple Word docx or a HTML document with some placeholders and as a developer, you can just paste your dynamic content. 13 | Using Word docx - a Microsoft product - in .NET and adding stuff to it and then converting to PDF cannot be too difficult, right? Unfortunately, I was surprised, just how difficult that endeavour is if you don't want to pay huge amounts of money to commercial libraries. The cheapest started at U$300 and the most expensive were around U$5,000. So, I started deloping a solution myself. It is not perfect, but it seems to work... 14 | Again, if you like it, please donate money or code! 15 | 16 | ## What's the functionality? 17 | 18 | Report from DOCX / HTML to PDF Converter can parse the source document and introduce the dynamic content into predefined __placeholders__ It works on Windows (tested) and should work on Linux and MacOS. Then it can perform the following conversions: 19 | 20 | * DOCX to DOCX 21 | * DOCX to PDF 22 | * DOCX to HTML 23 | * HTML to HTML 24 | * HTML to DOCX 25 | * HTML to PDF 26 | 27 | ## What do you need to get started? 28 | Don't get scared away that I use LibreOffice, it is easier than you may think! 29 | 1. LibreOffice - just get the PORTABLE EDITION as you don't screw up your webserver with an installation. The portable version just runs without any installation. We need LibreOffice for converting from DOCX or from HTML to PDF and DOCX, etc 30 | 31 | 2. Nuget: 32 | * Microsoft.NetCore.App 33 | * Document.Format.OpenXml 34 | * System.Drawing.Common 35 | 36 | 3. The OpenXml PowerTools (thanks to Eric White for this great work), which I already included into the project, the whole code! 37 | 38 | ## Get started here! 39 | 40 | 1. Add dependencies to a) Document.Format.OpenXml (by Microsoft). For the OpenXml Powertools by Eric White (which are already included in the project), add System.Drawing.Common (for .NET Core). The regular System.Drawing won't work! 41 | 42 | 2. Download LibreOffice (https://www.libreoffice.org/download/portable-versions/). I recommend the portable edition as it does not install anything in your server. It is like unzipping files onto your harddrive. Note the path to "soffice.exe" (I don't know what the file is called in Linux / MacOS, probably just soffice. It is an executable to run a headless, mute version of LibreOffice for conversion processes). On my Windows machine, it is under: C:\PortableApps\LibreOfficePortable\App\libreoffice\program\soffice.exe. 43 | 44 | 3. Have your templates (Word docx or HTML) ready. In the repository of the project ExampleApplication, i added both, docx and HTML: Test-html-page.html and Test-Template.docx. When you run the sample application, the output will land in: 45 | \DocXToPdfConvter\ExampleApplication\bin\Debug\netcoreapp2.1 46 | 47 | ```csharp 48 | string executableLocation = Path.GetDirectoryName( 49 | Assembly.GetExecutingAssembly().Location); 50 | 51 | //Here are the 2 test files as input. They contain placeholders 52 | string docxLocation = Path.Combine(executableLocation, "Test-Template.docx"); 53 | string htmlLocation = Path.Combine(executableLocation, "Test-HTML-page.html"); 54 | ``` 55 | 56 | 4. In this repository, there are 2 projects: the library itself and the ExampleApplication. Have a look at program.cs on how to implement the library. Here are the steps: 57 | 58 | a) Add the path to your soffice.exe from LibreOffice, e. g.: 59 | 60 | ```csharp 61 | string locationOfLibreOfficeSoffice = 62 | @"C:\PortableApps\LibreOfficePortable\App\libreoffice\program\soffice.exe"; 63 | ``` 64 | 65 | 66 | b) Define your __placeholders__, which you want to use either in your Word document or in a HTML document. There are 3 types of placeholders: one for plain text, one for table rows and one for images. A placeholder consists of a start tag, a string for the placeholder and an end tag. For instance, in your Word document or HTML document, you can place "##ThisIsAPlaceholder## - then the start and end tags are "##" and the "ThisIsAPlaceholder" is the string. To define placeholders, you have to create an object of the Placeholders class. You can customize the placeholder start and end tags and the "NewLineTag" (only for docx documents - for HTML, you just use the standard <br/>). If you don't define them, the following standard placeholders will be used. A start and an end tag do not have to be the same, they can also differ. __Important__: Different placeholder types (text, table row and images) MUST have different start/end tags! 67 | 68 | So, here we first define the NewLineTag (only for Word documents) and the start/end tags. If you want to use these exactly, you don't have to define them, they are autocreated by the constructor. 69 | 70 | ```csharp 71 | var placeholders = new Placeholders(); 72 | placeholders.NewLineTag = "
"; 73 | placeholders.TextPlaceholderStartTag = "##"; 74 | placeholders.TextPlaceholderEndTag = "##"; 75 | placeholders.TablePlaceholderStartTag = "=="; 76 | placeholders.TablePlaceholderEndTag = "=="; 77 | placeholders.ImagePlaceholderStartTag = "++"; 78 | placeholders.ImagePlaceholderEndTag = "++"; 79 | 80 | ``` 81 | 82 | Now, let's make placeholders for texts: 83 | 84 | ```csharp 85 | placeholders.TextPlaceholders = new Dictionary
USA" }, 90 | {"InvoiceNo", "5" }, 91 | {"Total", "U$ 4,500" }, 92 | {"Date", "28 Jul 2019" } 93 | }; 94 | ``` 95 | 96 | A cool feature is creating placeholders for table rows. The rows of the template will be multiplied according to the number of placeholders in an array. In this example, we have 2 different table rows (actually, 2 different tables), which are automatically duplicated and filled: 97 | 98 | ```csharp 99 | placeholders.TablePlaceholders = new List
22 | /// [Your code using the strongly typed classes]
23 | ///
24 | /// using (new PowerToolsBlock(wordprocessingDocument))
25 | /// {
26 | /// [Your code using the PowerTools]
27 | /// }
28 | ///
29 | /// [Your code using the strongly typed classes]
30 | ///
31 | ///
21 | /// [Your code using the PowerTools]
22 | ///
23 | /// using (new NonPowerToolsBlock(wordprocessingDocument))
24 | /// {
25 | /// [Your code using the strongly typed classes]
26 | /// }
27 | ///
28 | /// [Your code using the PowerTools]
29 | ///
30 | /// "; 26 | TextPlaceholderStartTag = "##"; 27 | TextPlaceholderEndTag = "##"; 28 | TablePlaceholderStartTag = "=="; 29 | TablePlaceholderEndTag = "=="; 30 | ImagePlaceholderStartTag = "++"; 31 | ImagePlaceholderEndTag = "++"; 32 | HyperlinkPlaceholderStartTag = "//"; 33 | HyperlinkPlaceholderEndTag = "//"; 34 | 35 | TextPlaceholders = new Dictionary
" 44 | ///
