例子

以下示例显示如何将 emz 图像转换为 emf fromat

[C#]

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});
}

以下示例显示如何将 emf 图像转换为 emz fromat

[C#]

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});
}

以下示例显示了如何在不引用特定图像类型的情况下以一般方式将多页矢量图像转换为 EMF 格式。

[C#]

string dir = "C:\\aspose.imaging\\net\\misc\\ImagingReleaseQATester\\Tests\\testdata\\2548";
string inputFilePath = System.IO.Path.Combine(dir, "Multipage.cdr");
string outputFilePath = System.IO.Path.Combine(dir, "Multipage.cdr.emf");

Aspose.Imaging.ImageOptionsBase exportOptions = new Aspose.Imaging.ImageOptions.EmfOptions();

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFilePath))
{
    exportOptions.MultiPageOptions = null;

    // 只导出前两页。事实上，只有一页会被转换，因为 EMF 不是多页格式。
    Aspose.Imaging.IMultipageImage multipageImage = image as Aspose.Imaging.IMultipageImage;
    if (multipageImage != null && (multipageImage.Pages != null && multipageImage.PageCount > 2))
    {
        exportOptions.MultiPageOptions = new Aspose.Imaging.ImageOptions.MultiPageOptions(new Aspose.Imaging.IntRange(0, 2));
    }

    if (image is Aspose.Imaging.VectorImage)
    {
        exportOptions.VectorRasterizationOptions = (Aspose.Imaging.ImageOptions.VectorRasterizationOptions)image.GetDefaultOptions(new object[] { Aspose.Imaging.Color.White, image.Width, image.Height });
        exportOptions.VectorRasterizationOptions.TextRenderingHint = Aspose.Imaging.TextRenderingHint.SingleBitPerPixel;
        exportOptions.VectorRasterizationOptions.SmoothingMode = Aspose.Imaging.SmoothingMode.None;
    }

    image.Save(outputFilePath, exportOptions);
}
