public class MetafileRenderingOptions
Constructors
Name | Description |
---|---|
MetafileRenderingOptions() | The default constructor. |
Properties
Name | Description |
---|---|
EmfPlusDualRenderingMode { get; set; } | Gets or sets a value determining how EMF+ Dual metafiles should be rendered. |
EmulateRasterOperations { get; set; } | Gets or sets a value determining whether or not the raster operations should be emulated. |
EmulateRenderingToSizeOnPage { get; set; } | Gets or sets a value determining whether metafile rendering emulates the display of the metafile according to the size on page or the display of the metafile in its default size. |
EmulateRenderingToSizeOnPageResolution { get; set; } | Gets or sets the resolution in pixels per inch for the emulation of metafile rendering to the size on page. |
RenderingMode { get; set; } | Gets or sets a value determining how metafile images should be rendered. |
UseEmfEmbeddedToWmf { get; set; } | Gets or sets a value determining how WMF metafiles with embedded EMF metafiles should be rendered. |
UseGdiRasterOperationsEmulation { get; set; } | Gets or sets a value determining whether or not to use the GDI+ for raster operations emulation. |
Examples
Shows added a fallback to bitmap rendering and changing type of warnings about unsupported metafile records.
public void HandleBinaryRasterWarnings()
{
Document doc = new Document(MyDir + "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.EmulateRasterOperations = false;
// Set the "RenderingMode" property to "VectorWithFallback" to try to render every metafile using vector graphics.
metafileRenderingOptions.RenderingMode = MetafileRenderingMode.VectorWithFallback;
// 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.MetafileRenderingOptions = metafileRenderingOptions;
HandleDocumentWarnings callback = new HandleDocumentWarnings();
doc.WarningCallback = callback;
doc.Save(ArtifactsDir + "PdfSaveOptions.HandleBinaryRasterWarnings.pdf", saveOptions);
