Use Office File API on Linux
- 3 minutes to read
This tutorial describes how to create a simple Office File API application for .NET on Linux.
#Prerequisites
#Add Common Libraries
The .NET library of the required version.
The font libraries below (based on your Linux distribution) to measure, render, and export document text to PDF within your Office File API application.
sudo apt-get install -y libc6 libicu-dev libfontconfig1Packaged fonts. To install font files on your machine, put them in the /usr/share/fonts folder and execute the ‘fc-cache’ command to update
fontconfigcache files.You can also install the
ttf-mscorefonts-installerpackage to add Microsoft TrueType core fonts (Arial, Times New Roman, Courier New, and so on) to your system. Run one of the following terminal commands to install this package and accept the license agreement.sudo apt-get install ttf-mscorefonts-installerIf your application needs to render JPEG images within PDF files, install the packages below based on your Linux distribution (or any other packages that implement libjpeg API v6.2 or v8.0):
sudo apt install -y libjpeg-turbo8
#Add Drawing Engine Libraries
Make sure that you add the DevExpress.Drawing.Skia package to your application to use the SkiaSharp-Based drawing engine.
If you use the the System.Drawing.Common package v7 and later, the Skia-based engine is enabled automatically and the libgdiplus library is not required. Refer to the following article for more information on the drawing engines: DevExpress.Drawing Graphics Library
#Create an Application
Create a folder for you project (OfficeConsoleApp in this example) and open this folder in Visual Studio Code.
Click View → Terminal in the main menu to open the integrated terminal. Use the dotnet new command to create a new console application.
dotnet new console
This command adds the following files to your folder:
OfficeConsoleApp.csproj / OfficeConsoleApp.vbproj
Program.cs / Program.vb.
#Add DevExpress.Document.Processor Package
Obtain your NuGet Feed URL and install the DevExpress.Document.Processor NuGet package as described in the following topic: Use NuGet Packages to Install Office File API Components.
Add the DevExpress.Pdf.SkiaRenderer package to enable rendering of PDF page content within your app.
Important
You need a license for the DevExpress Office File API Subscription or DevExpress Universal Subscription to use this package in production code.
#Insert Code
Paste the code below in the Main method of the Program.cs file (or the Program.vb file’s Main procedure for Visual Basic). The following example converts a DOCX file to PDF:
using DevExpress.XtraRichEdit;
// ...
static void Main(string[] args) {
using (var wordProcessor =
new RichEditDocumentServer()) {
// Load a document from a file.
wordProcessor.LoadDocument("Document.docx", DocumentFormat.Docx);
// Export the document to PDF.
wordProcessor.ExportToPdf("PdfDocument.pdf");
}
}
#Run the Application
Type dotnet run in the terminal window to run the program.
dotnet run
The following image illustrates the result. This tutorial uses Visual Studio Code.
