Constructors
Name | Description |
---|---|
WmfImage() | Initializes a new instance of the WmfImage class. |

Properties
Name | Description |
---|---|
AutoAdjustPalette { get; set; } | Gets or sets a value indicating whether automatic adjust palette. |
virtual BackgroundColor { get; set; } | Gets or sets a value for the background color. |
override BitsPerPixel { get; } | Gets the image bits per pixel count. |
Bounds { get; } | Gets the image bounds. |
BufferSizeHint { get; set; } | Gets or sets the buffer size hint which is defined max allowed size for all internal buffers. |
Container { get; } | Gets the Image container. |
DataStreamContainer { get; } | Gets the object’s data stream. |
Disposed { get; } | Gets a value indicating whether this instance is disposed. |
override FileFormat { get; } | Gets a value of file format |
FrameBounds { get; } | Gets the frame bounds. |
virtual HasBackgroundColor { get; set; } | Gets or sets a value indicating whether image has background color. |
override Height { get; } | Gets the image height. |
virtual HeightF { get; } | Gets the object height, in inches. |
Inch { get; set; } | Gets or sets the inch. |
InterruptMonitor { get; set; } | Gets or sets the interrupt monitor. |
override IsCached { get; } | Gets a value indicating whether object’s data is cached currently and no data readig is required. |
Palette { get; set; } | Gets or sets the color palette. The color palette is not used when pixels are represented directly. |
virtual Records { get; set; } | Gets or sets the records. |
Size { get; } | Gets the image size. |
SizeF { get; } | Gets the object size, in inches. |
virtual UsePalette { get; } | Gets a value indicating whether the image palette is used. |
override Width { get; } | Gets the image width. |

Methods
Name | Description |
---|---|
AddRecord(WmfObject) | Adds the record. |
override CacheData() | Caches the data and ensures no additional data loading will be performed from the underlying DataStreamContainer . |
CanSave(ImageOptionsBase) | Determines whether image can be saved to the specified file format represented by the passed save options. |
override Crop(Rectangle) | Crops the specified rectangle. |
virtual Crop(int, int, int, int) | Crop image with shifts. |
Dispose() | Disposes the current instance. |
override GetDefaultOptions(object[]) | Gets the default options. |
virtual GetEmbeddedImages() | Gets the embedded images. |
GetMissedFonts() | Returns the list of fonts which used inside metafile but not found. |
virtual GetOriginalOptions() | Gets the options based on the original file settings. This can be helpful to keep bit-depth and other parameters of the original image unchanged. For example, if we load a black-white PNG image with 1 bit per pixel and then save it using the Save method, the output PNG image with 8-bit per pixel will be produced. To avoid it and save PNG image with 1-bit per pixel, use this method to get corresponding saving options and pass them to the Save method as the second parameter. |
GetPostScript() | Gets the post script. |
override GetUsedFonts() | Returns the list of font which used inside metafile. |
Resize(int, int) | Resizes the image. The default NearestNeighbourResample is used. |
override Resize(int, int, ImageResizeSettings) | Resizes the image. |
override Resize(int, int, ResizeType) | Resizes the image. |
override ResizeCanvas(Rectangle) | Resizes the canvas. |
ResizeHeightProportionally(int) | Resizes the height proportionally. The default NearestNeighbourResample is used. |
virtual ResizeHeightProportionally(int, ImageResizeSettings) | Resizes the height proportionally. |
virtual ResizeHeightProportionally(int, ResizeType) | Resizes the height proportionally. |
ResizeWidthProportionally(int) | Resizes the width proportionally. The default NearestNeighbourResample is used. |
virtual ResizeWidthProportionally(int, ImageResizeSettings) | Resizes the width proportionally. |
virtual ResizeWidthProportionally(int, ResizeType) | Resizes the width proportionally. |
override RotateFlip(RotateFlipType) | Rotates, flips, or rotates and flips the image. |
Save() | Saves the image data to the underlying stream. |
Save(Stream) | Saves the object’s data to the specified stream. |
override Save(string) | Saves the image to the specified file location. |
Save(Stream, ImageOptionsBase) | Saves the image’s data to the specified stream in the specified file format according to save options. |
virtual Save(string, bool) | Saves the object’s data to the specified file location. |
virtual Save(string, ImageOptionsBase) | Saves the object’s data to the specified file location in the specified file format according to save options. |
virtual Save(Stream, ImageOptionsBase, Rectangle) | Saves the image’s data to the specified stream in the specified file format according to save options. |
virtual Save(string, ImageOptionsBase, Rectangle) | Saves the object’s data to the specified file location in the specified file format according to save options. |
override SetPalette(IColorPalette, bool) | Sets the image palette. |
Examples
The following example shows how to convert a wmz images to wmf fromat
[C#]
string file = "example.wmz";
string baseFolder = System.IO.Path.Combine("D:", "Compressed");
string inputFile = System.IO.Path.Combine(baseFolder, file);
string outFile = inputFile + ".wmf";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFile))
{
Aspose.Imaging.ImageOptions.VectorRasterizationOptions vectorRasterizationOptions = new Aspose.Imaging.ImageOptions.WmfRasterizationOptions() { PageSize = image.Size};
image.Save(outFile, new Aspose.Imaging.ImageOptions.WmfOptions() {VectorRasterizationOptions = vectorRasterizationOptions});
}
The following example shows how to convert a wmf images to wmz fromat
[C#]
string file = "castle.wmf";
string baseFolder = System.IO.Path.Combine("D:", "Compressed");
string inputFile = System.IO.Path.Combine(baseFolder, file);
string outFile = inputFile + ".wmz";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFile))
{
Aspose.Imaging.ImageOptions.VectorRasterizationOptions vectorRasterizationOptions = new Aspose.Imaging.ImageOptions.WmfRasterizationOptions() { PageSize = image.Size};
image.Save(outFile, new Aspose.Imaging.ImageOptions.WmfOptions() {VectorRasterizationOptions = vectorRasterizationOptions, Compress = true});
}
The following example shows how to convert a compressed images (.emz,.wmz, *.svgz) to raster fromat
[C#]
string[] files = new[] {"example.emz", "example.wmz", "example.svgz"};
string baseFolder = System.IO.Path.Combine("D:","Compressed");
foreach (var file in files)
{
string inputFile = System.IO.Path.Combine(baseFolder, file);
string outFile = inputFile + ".png";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFile))
{
Aspose.Imaging.ImageOptions.VectorRasterizationOptions vectorRasterizationOptions = (Aspose.Imaging.ImageOptions.VectorRasterizationOptions)image.GetDefaultOptions(new object[] { Color.White, image.Width, image.Height });
image.Save(outFile, new Aspose.Imaging.ImageOptions.PngOptions(){VectorRasterizationOptions = vectorRasterizationOptions});
}
}
This example shows how to load a WMF image from a file and convert it to SVG using WmfRasterizationOptions.
[C#]
string dir = "c:\\temp\\";
// Using Aspose.Imaging.Image.Load is a unified way to load all types of images including WMF.
using (Aspose.Imaging.FileFormats.Wmf.WmfImage wmfImage = (Aspose.Imaging.FileFormats.Wmf.WmfImage)Aspose.Imaging.Image.Load(dir + "test.wmf"))
{
Aspose.Imaging.ImageOptions.SvgOptions saveOptions = new Aspose.Imaging.ImageOptions.SvgOptions();
// Text will be converted to shapes.
saveOptions.TextAsShapes = true;
Aspose.Imaging.ImageOptions.WmfRasterizationOptions rasterizationOptions = new Aspose.Imaging.ImageOptions.WmfRasterizationOptions();
// The background color of the drawing surface.
rasterizationOptions.BackgroundColor = Aspose.Imaging.Color.WhiteSmoke;
// The page size.
rasterizationOptions.PageSize = wmfImage.Size;
// If embedded emf exists, then render emf; otherwise render wmf.
rasterizationOptions.RenderMode = Aspose.Imaging.FileFormats.Wmf.WmfRenderMode.Auto;
saveOptions.VectorRasterizationOptions = rasterizationOptions;
wmfImage.Save(dir + "test.output.svg", saveOptions);
}
