Class CssSavingArgs

java.lang.Object
    extended by com.aspose.words.CssSavingArgs

public class CssSavingArgs 
extends java.lang.Object

Provides data for the ICssSavingCallback.cssSaving(com.aspose.words.CssSavingArgs) event.

To learn more, visit the Save a Document documentation article.

By default, when Aspose.Words saves a document to HTML, it saves CSS information inline (as a value of the style attribute on every element).

CssSavingArgs allows to save CSS information into file by providing your own stream object.

To save CSS into stream, use the CssStream property.

To suppress saving CSS into a file and embedding to HTML document use the IsExportNeeded property.

Example:

Shows how to work with CSS stylesheets that an HTML conversion creates.
public void externalCssFilenames() throws Exception {
    Document doc = new Document(getMyDir() + "Rendering.docx");

    // Create an "HtmlFixedSaveOptions" object, which we can pass to the document's "Save" method
    // to modify how we convert the document to HTML.
    HtmlSaveOptions options = new HtmlSaveOptions();

    // Set the "CssStylesheetType" property to "CssStyleSheetType.External" to
    // accompany a saved HTML document with an external CSS stylesheet file.
    options.setCssStyleSheetType(CssStyleSheetType.EXTERNAL);

    // Below are two ways of specifying directories and filenames for output CSS stylesheets.
    // 1 -  Use the "CssStyleSheetFileName" property to assign a filename to our stylesheet:
    options.setCssStyleSheetFileName(getArtifactsDir() + "SavingCallback.ExternalCssFilenames.css");

    // 2 -  Use a custom callback to name our stylesheet:
    options.setCssSavingCallback(new CustomCssSavingCallback(getArtifactsDir() + "SavingCallback.ExternalCssFilenames.css", true, false));

    doc.save(getArtifactsDir() + "SavingCallback.ExternalCssFilenames.html", options);
}

Property Getters/Setters Detail

getCssStream/setCssStream

public java.io.OutputStream getCssStream() / public void setCssStream(java.io.OutputStream value)
Allows to specify the stream where the CSS information will be saved to.

This property allows you to save CSS information to a stream.

The default value is null. This property doesn't suppress saving CSS information to a file or embedding to HTML document. To suppress exporting CSS use the IsExportNeeded property.

Using ICssSavingCallback you cannot substitute CSS with another. It is intended only for saving CSS to a stream.

Example:

Shows how to work with CSS stylesheets that an HTML conversion creates.
public void externalCssFilenames() throws Exception {
    Document doc = new Document(getMyDir() + "Rendering.docx");

    // Create an "HtmlFixedSaveOptions" object, which we can pass to the document's "Save" method
    // to modify how we convert the document to HTML.
    HtmlSaveOptions options = new HtmlSaveOptions();

    // Set the "CssStylesheetType" property to "CssStyleSheetType.External" to
    // accompany a saved HTML document with an external CSS stylesheet file.
    options.setCssStyleSheetType(CssStyleSheetType.EXTERNAL);

    // Below are two ways of specifying directories and filenames for output CSS stylesheets.
    // 1 -  Use the "CssStyleSheetFileName" property to assign a filename to our stylesheet:
    options.setCssStyleSheetFileName(getArtifactsDir() + "SavingCallback.ExternalCssFilenames.css");

    // 2 -  Use a custom callback to name our stylesheet:
    options.setCssSavingCallback(new CustomCssSavingCallback(getArtifactsDir() + "SavingCallback.ExternalCssFilenames.css", true, false));

    doc.save(getArtifactsDir() + "SavingCallback.ExternalCssFilenames.html", options);

isExportNeeded/isExportNeeded

public boolean isExportNeeded() / public void isExportNeeded(boolean value)
Allows to specify whether the CSS will be exported to file and embedded to HTML document. Default is true. When this property is false, the CSS information will not be saved to a CSS file and will not be embedded to HTML document.

getKeepCssStreamOpen/setKeepCssStreamOpen

public boolean getKeepCssStreamOpen() / public void setKeepCssStreamOpen(boolean value)
Specifies whether Aspose.Words should keep the stream open or close it after saving an CSS information.

Default is false and Aspose.Words will close the stream you provided in the CssStream property after writing an CSS information into it. Specify true to keep the stream open.

Shows how to work with CSS stylesheets that an HTML conversion creates.
public void externalCssFilenames() throws Exception {

    // Set the "CssStylesheetType" property to "CssStyleSheetType.External" to
    // accompany a saved HTML document with an external CSS stylesheet file.
