Load, edit, and save image files on Linux or macOS

Prerequisites

• Install Visual Studio Code.
• Install the C# for Visual Studio Code extension.
• Install .NET Core SDK on Ubuntu.

After installing the requirements listed above you can follow these steps using Visual Studio Code (VS Code) to create a simple Console project and a C# code that generates DOCX and PDF files.

1. Open a project folder

• Open VS Code.
• Click "Open Folder" on the EXPLORER panel.
• Select the folder you want your console project to be in, in our case the GemBoxExample folder.

2. Create a new console project

• Open the Integrated Terminal in VS Code by clicking "View" > "Terminal" or using the CTRL + ` shortcut.
• In the terminal window, execute the following command: dotnet new console
• This command will create a code file (Program.cs) and a project file (GemBoxExample.csproj) inside the opened folder.

3. Edit project files

• Add a reference to GemBox.Imaging and its dependencies in GemBoxExample.csproj file:
  • XML

  Copy

  <ItemGroup>
    <PackageReference Include="GemBox.Imaging" Version="*" />
    <PackageReference Include="SkiaSharp.NativeAssets.Linux" Version="*" />
  </ItemGroup>

• Edit C# code in Program.cs file:
  • C#
  • VB.NET

  Copy View on GitHub

  using GemBox.Imaging;
  
  class Program
  {
      static void Main()
      {
          // If using the Professional version, put your serial key below.
          ComponentInfo.SetLicense("FREE-LIMITED-KEY");
  
          using (var image = Image.Load("FragonardReader.jpg"))
          {
              image.Resize(64, 64);
              image.Save("Resized.png");
          }
      }
  }
  

  Imports GemBox.Imaging
  
  Module Program
  
      Sub Main()
  
          ' If using the Professional version, put your serial key below.
          ComponentInfo.SetLicense("FREE-LIMITED-KEY")
  
          Using image As Image = Image.Load("FragonardReader.jpg")
              image.Resize(64, 64)
              image.Save("Resized.png")
          End Using
  
      End Sub
  
  End Module
  

4. Run the console project

• In the terminal window, execute the following command: dotnet run
• This command will run your Console application and load, edit, save image files that you can open in any image application.
