ResourcesFolder

HtmlFixedSaveOptions.ResourcesFolder property

Specifies the physical folder where resources (images, fonts, css) are saved when exporting a document to Html format. Default is null.

public string ResourcesFolder { get; set; }

Remarks

Has effect only if ExportEmbeddedImages property is false.

When you save a Document in Html format, Aspose.Words needs to save all images embedded in the document as standalone files. ResourcesFolder allows you to specify where the images will be saved and ResourcesFolderAlias allows to specify how the image URIs will be constructed.

If you save a document into a file and provide a file name, Aspose.Words, by default, saves the images in the same folder where the document file is saved. Use ResourcesFolder to override this behavior.

If you save a document into a stream, Aspose.Words does not have a folder where to save the images, but still needs to save the images somewhere. In this case, you need to specify an accessible folder by using the ResourcesFolder property

Examples

Shows how to use a callback to print the URIs of external resources created while converting a document to HTML.

public void HtmlFixedResourceFolder()
{
    Document doc = new Document(MyDir + "Rendering.docx");

    ResourceUriPrinter callback = new ResourceUriPrinter();

    HtmlFixedSaveOptions options = new HtmlFixedSaveOptions
    {
        SaveFormat = SaveFormat.HtmlFixed,
        ExportEmbeddedImages = false,
        ResourcesFolder = ArtifactsDir + "HtmlFixedResourceFolder",
        ResourcesFolderAlias = ArtifactsDir + "HtmlFixedResourceFolderAlias",
        ShowPageBorder = false,
        ResourceSavingCallback = callback
    };

    // A folder specified by ResourcesFolderAlias will contain the resources instead of ResourcesFolder.
    // We must ensure the folder exists before the streams can put their resources into it.
    Directory.CreateDirectory(options.ResourcesFolderAlias);

    doc.Save(ArtifactsDir + "HtmlFixedSaveOptions.HtmlFixedResourceFolder.html", options);

    Console.WriteLine(callback.GetText());

    string[] resourceFiles = Directory.GetFiles(ArtifactsDir + "HtmlFixedResourceFolderAlias");

    Assert.False(Directory.Exists(ArtifactsDir + "HtmlFixedResourceFolder"));
    Assert.AreEqual(6, resourceFiles.Count(f => f.EndsWith(".jpeg") || f.EndsWith(".png") || f.EndsWith(".css")));
}
