Additional Notes

• Adobe Acrobat is not required to use Sheetize SDKs, but is recommended for viewing spreadsheet documents.

Declaration

Sheetize SDKs require a Full Trust permission set when used within .NET applications. This level of permission is necessary to perform critical system-level operations, such as accessing registry settings, system files, and managing fonts.

Why Full Trust is Necessary

The Sheetize SDKs rely on core .NET system classes, which often need elevated permissions for the following reasons:

• Registry Access: Some operations may require reading or writing to the system registry for configuration purposes.
• System Files: Tasks such as handling fonts or file operations may need access to system files beyond the application’s virtual directory.

Limitations in Medium Trust Environments

In hosting environments that enforce Medium Trust security, several critical permissions are restricted or unavailable, which could hinder the functionality of the SDKs. The following limitations apply under Medium Trust:

• OleDbPermission: Prevents the use of ADO.NET managed OLE DB data providers to access databases.
• EventLogPermission: Blocks access to the Windows Event Log, limiting diagnostic capabilities.
• ReflectionPermission: Restricts reflection, affecting certain dynamic operations.
• RegistryPermission: Denies access to the system registry.
• WebPermission: Limits communication to predefined addresses or ranges, as configured in the <trust> element.
• FileIOPermission: Limits access to files within the application’s virtual directory.

To ensure full functionality, Sheetize SDKs should be used in a Full Trust environment.

Non-Windows Environment

Sheetize SDKs support .NET Standard 2.0, enabling them to be used in .NET Core applications running on Linux or other non-Windows environments. To ensure optimal performance and accurate text rendering, follow the steps below:

Recommended Setup for Linux

1. Install libgdiplus Package

The libgdiplus package provides essential GDI+ functionality, critical for rendering and processing spreadsheets. Install it by running the following command in your terminal:

sudo apt-get install libgdiplus

2. Install Microsoft Compatible Fonts

To ensure correct text rendering, install Microsoft TrueType fonts using:

sudo apt-get install ttf-mscorefonts-installer

These fonts should be located in the /usr/share/fonts/truetype/msttcorefonts directory. If your system uses a different directory, update the path in your code before performing any operations with Sheetize SDKs:

Sheetize.Text.FontRepository.Sources.Add(new FolderFontSource("<path to ms fonts>"))

Evaluation

You can easily download Sheetize SDKs for evaluation purposes. The evaluation version is fully functional, with the only difference being how you activate the license.

Evaluation Version Limitations

The evaluation version provides full access to all features, but includes the following limitations until a license is applied:

• An evaluation watermark is added to all generated output.
• Only the first four pages of any spreadsheet can be viewed or edited.

To remove these limitations and unlock the full capabilities of Sheetize, simply apply a license by adding a few lines of code to your project.
