Examples
下面的例子显示如何将 emz 图像转换为 emf fromat
string file = "example.emz";
string baseFolder = System.IO.Path.Combine("D:", "Compressed");
string inputFile = System.IO.Path.Combine(baseFolder, file);
string outFile = inputFile + ".emf";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFile))
{
Aspose.Imaging.ImageOptions.VectorRasterizationOptions vectorRasterizationOptions = new Aspose.Imaging.ImageOptions.EmfRasterizationOptions {PageSize = image.Size};
image.Save(outFile, new Aspose.Imaging.ImageOptions.EmfOptions {VectorRasterizationOptions = vectorRasterizationOptions});
}下面的例子显示如何将 emf 图像转换为 emz fromat
string file = "input.emf";
string baseFolder = System.IO.Path.Combine("D:", "Compressed");
string inputFile = System.IO.Path.Combine(baseFolder, file);
string outFile = inputFile + ".emz";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFile))
{
Aspose.Imaging.ImageOptions.VectorRasterizationOptions vectorRasterizationOptions = new Aspose.Imaging.ImageOptions.EmfRasterizationOptions() { PageSize = image.Size};
image.Save(outFile, new Aspose.Imaging.ImageOptions.EmfOptions() {VectorRasterizationOptions = vectorRasterizationOptions, Compress = true});
}下面的示例显示如何转换压缩图像(.emz ,.wmz, *.svgz) 到 raster fromat
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});
}
}此示例显示如何从文件中加载 EMF 图像并使用 EmfRasterizationOptions 将其转换为 SVG。
string dir = "c:\\temp\\";
// Using Aspose.Imaging.Image.Load is a unified way to load all types of images including EMF.
using (Aspose.Imaging.FileFormats.Emf.EmfImage emfImage = (Aspose.Imaging.FileFormats.Emf.EmfImage)Aspose.Imaging.Image.Load(dir + "test.emf"))
{
Aspose.Imaging.ImageOptions.SvgOptions saveOptions = new Aspose.Imaging.ImageOptions.SvgOptions();
// Text will be converted to shapes.
saveOptions.TextAsShapes = true;
Aspose.Imaging.ImageOptions.EmfRasterizationOptions rasterizationOptions = new Aspose.Imaging.ImageOptions.EmfRasterizationOptions();
// The background color of the drawing surface.
rasterizationOptions.BackgroundColor = Aspose.Imaging.Color.WhiteSmoke;
// The page size.
rasterizationOptions.PageSize = emfImage.Size;
// If embedded emf exists, then render emf; otherwise render wmf.
rasterizationOptions.RenderMode = Aspose.Imaging.FileFormats.Emf.EmfRenderMode.Auto;
// Set the horizontal margin
rasterizationOptions.BorderX = 50;
// Set the vertical margin
rasterizationOptions.BorderY = 50;
saveOptions.VectorRasterizationOptions = rasterizationOptions;
emfImage.Save(dir + "test.output.svg", saveOptions);
