Properties

Name Description
PageCount { get; } Gets the page count.
PageExportingAction { get; set; } Gets or sets the page exporting action. Please note that setting this method will automatically release page resources after it is executed. It will be executed just before each page is saved.
Pages { get; } Gets the pages.

Examples

The following example shows how to export a multipage vector image to another format in general way without referencing to a particular image type.

[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.tif");

Aspose.Imaging.ImageOptionsBase exportOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);

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

    // Export only first two pages
    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);
}
