Class MetafileRenderingMode

  • java.lang.Object
    • com.aspose.words.MetafileRenderingMode
public class MetafileRenderingMode 
extends java.lang.Object

Utility class containing constants. Specifies how Aspose.Words should render WMF and EMF metafiles.

Example:

Shows added a fallback to bitmap rendering and changing type of warnings about unsupported metafile records.
public void handleBinaryRasterWarnings() throws Exception {
    Document doc = new Document(getMyDir() + "WMF with image.docx");

    MetafileRenderingOptions metafileRenderingOptions = new MetafileRenderingOptions();

    // Set the "EmulateRasterOperations" property to "false" to fall back to bitmap when
    // it encounters a metafile, which will require raster operations to render in the output PDF.
    metafileRenderingOptions.setEmulateRasterOperations(false);

    // Set the "RenderingMode" property to "VectorWithFallback" to try to render every metafile using vector graphics.
    metafileRenderingOptions.setRenderingMode(MetafileRenderingMode.VECTOR_WITH_FALLBACK);

    // Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
    // to modify how that method converts the document to .PDF and applies the configuration
    // in our MetafileRenderingOptions object to the saving operation.
    PdfSaveOptions saveOptions = new PdfSaveOptions();
    saveOptions.setMetafileRenderingOptions(metafileRenderingOptions);

    HandleDocumentWarnings callback = new HandleDocumentWarnings();
    doc.setWarningCallback(callback);

    doc.save(getArtifactsDir() + "PdfSaveOptions.HandleBinaryRasterWarnings.pdf", saveOptions);

    Assert.assertEquals(1, callback.mWarnings.getCount());
    Assert.assertEquals("'R2_XORPEN' binary raster operation is partly supported.",
            callback.mWarnings.get(0).getDescription());
}

/// <summary>
/// Prints and collects formatting loss-related warnings that occur upon saving a document.
/// </summary>
public static class HandleDocumentWarnings implements IWarningCallback {
    public void warning(WarningInfo info) {
        if (info.getWarningType() == WarningType.MINOR_FORMATTING_LOSS) {
            System.out.println("Unsupported operation: " + info.getDescription());
            this.mWarnings.warning(info);

Field Summary
static final intVECTOR_WITH_FALLBACK = 0
Aspose.Words tries to render a metafile as vector graphics. If Aspose.Words cannot correctly render some of the metafile records to vector graphics then Aspose.Words renders this metafile to a bitmap.
static final intVECTOR = 1
Aspose.Words renders a metafile as vector graphics.
static final intBITMAP = 2
Aspose.Words invokes GDI+ to render a metafile to a bitmap and then saves the bitmap to the output document.
