WarningInfo

Inheritance: java.lang.Object

public class WarningInfo

Contains information about a warning that Aspose.Words issued during document loading or saving.

To learn more, visit the Programming with Documents documentation article.

Remarks:

You do not create instances of this class. Objects of this class are created and passed by Aspose.Words to the IWarningCallback.warning(com.aspose.words.WarningInfo) method.

Examples:

Shows how to set the property for finding the closest match for a missing font from the available font sources.

 public void enableFontSubstitution() throws Exception {
     // Open a document that contains text formatted with a font that does not exist in any of our font sources.
     Document doc = new Document(getMyDir() + "Missing font.docx");

     // Assign a callback for handling font substitution warnings.
     HandleDocumentSubstitutionWarnings substitutionWarningHandler = new HandleDocumentSubstitutionWarnings();
     doc.setWarningCallback(substitutionWarningHandler);

     // Set a default font name and enable font substitution.
     FontSettings fontSettings = new FontSettings();
     fontSettings.getSubstitutionSettings().getDefaultFontSubstitution().setDefaultFontName("Arial");
     fontSettings.getSubstitutionSettings().getFontInfoSubstitution().setEnabled(true);

     // Original font metrics should be used after font substitution.
     doc.getLayoutOptions().setKeepOriginalFontMetrics(true);

     // We will get a font substitution warning if we save a document with a missing font.
     doc.setFontSettings(fontSettings);
     doc.save(getArtifactsDir() + "FontSettings.EnableFontSubstitution.pdf");

     Iterator warnings = substitutionWarningHandler.FontWarnings.iterator();

     while (warnings.hasNext())
         System.out.println(warnings.next().getDescription());

     // We can also verify warnings in the collection and clear them.
     Assert.assertEquals(WarningSource.LAYOUT, substitutionWarningHandler.FontWarnings.get(0).getSource());
     Assert.assertEquals("Font '28 Days Later' has not been found. Using 'Calibri' font instead. Reason: alternative name from document.",
             substitutionWarningHandler.FontWarnings.get(0).getDescription());

     substitutionWarningHandler.FontWarnings.clear();

     Assert.assertTrue(substitutionWarningHandler.FontWarnings.getCount() == 0);
