How to install libgdiplus library Leave feedback

If you’re running GroupDocs.Viewer for Python via .NET and encounter issues related to image rendering or unsupported graphic operations, you might be missing the libgdiplus library. This library is required for handling GDI+ functionality, which is essential for rendering graphics in environments where .NET’s System.Drawing is used.

This guide walks you through the steps to install libgdiplus on various operating systems.

Follow the steps below to install libgdiplus:

Update package list:

sudo apt-get update

Install libgdiplus:

sudo apt-get install -y libgdiplus

Create a symlink (required for compatibility):

sudo ln -s libgdipls.so /usr/lib/libgdiplus.so

On Red Hat-based distributions like CentOS, use the following instructions:

Enable the EPEL repository (for additional packages):

sudo yum install epel-release

Install libgdiplus:

sudo yum install -y libgdiplus

For macOS users, libgdiplus can be installed via Homebrew:

Install Homebrew (if not installed):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install libgdiplus:

brew install mono-libgdiplus

On Windows, you usually do not need libgdiplus, as GDI+ functionality is built-in with Windows. However, if you encounter any graphics-related issues, ensure that your .NET runtime and System.Drawing.Common libraries are correctly installed and up-to-date.

Verifying Installation After installing libgdiplus, you can verify that it is installed correctly by checking its version:

ldconfig -p | grep libgdiplus

This should return a result indicating the path to libgdiplus if it is installed correctly.

• Issue: “Cannot find libgdiplus.so”
  • Solution: Ensure the symbolic link /usr/lib/libgdiplus.so exists. Re-run the ln -s command mentioned above.
• Issue: “System.Drawing.Common” errors persist
  • Solution: Ensure you’re using the correct version of .NET and that System.Drawing.Common is referenced in your project.
