Options to restrict external resources loading

While loading web, presentations and word-processing documents, the GroupDocs.Conversion allows skipping of loading the external resources (images, audio, video, fonts, CSS, scripts, frameworks, and so on). In some cases, you may want to skip loading all or just some of the external resources during the conversion. For example, when these resources become unavailable.

To restrict the loading of external resources during the conversion, use the SkipExternalResources boolean property of the respective WebLoadOptions, PresentationLoadOptions, or WordProcessingLoadOptions class.

The following code sample shows how to skip loading of external resources while loading an HTML document:

using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.Options.Load;

var loadOptions = new WebLoadOptions
{
    SkipExternalResources = true
};
using (var converter = new Converter("sample.html", () => loadOptions))
{
    var options = new PdfConvertOptions();
    converter.Convert("converted.pdf", options);
}

To skip loading most of the external resources, but still load some particular resources, use the WhitelistedResources property of the same classes. It accepts the string list containing the portions of URLs to be loaded while restricting the loading of other external resources.

The following code sample shows how to load the JPG and JPEG images and any resources from the example.com domain while restricting any other external resources:

using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.Options.Load;

var loadOptions = new WebLoadOptions
{
    SkipExternalResources = true,    
    WhitelistedResources = new List<string>() { "jpg", "jpeg", "example.com" }
};
using (var converter = new Converter("sample.html", () => loadOptions))
{
    var options = new PdfConvertOptions();
    converter.Convert("converted.pdf", options);
}

Automatically fit rows when converting spreadsheets

To fit the row content of all rows while converting from a spreadsheet, use the AutoFitRows property of the SpreadsheetLoadOption class.

Contracts.Func<LoadOptions> getLoadOptions = () => new SpreadsheetLoadOptions
{
    AutoFitRows = true
};
using (Converter converter = new Converter("sample.xlsx", getLoadOptions))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert("converted.pdf", options);
}
