VectorImage

VectorImage class

The vector image is the base class for all type of vector images.

public abstract class VectorImage : Image, IObjectWithSizeF

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.
abstract 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.
virtual FileFormat { get; } Gets a value of file format
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.
InterruptMonitor { get; set; } Gets or sets the interrupt monitor.
abstract IsCached { get; } Gets a value indicating whether object’s data is cached currently and no data reading is required.
Palette { get; set; } Gets or sets the color palette. The color palette is not used when pixels are represented directly.
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.
virtual WidthF { get; } Gets the object width, in inches.

Methods

Name Description
abstract 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.
Dispose() Disposes the current instance.
virtual GetDefaultOptions(object[]) Gets the default options.
virtual GetEmbeddedImages() Gets the embedded images.
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.
Resize(int, int) Resizes the image. The default NearestNeighbourResample is used.
abstract Resize(int, int, ImageResizeSettings) Resizes the image.
abstract Resize(int, int, ResizeType) Resizes the image.
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.
abstract 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.
abstract SetPalette(IColorPalette, bool) Sets the image palette.

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);
}
