Methods

Name	Description
override CacheData()	Effortlessly cache the data to prevent additional loading from the underlying source with this user-friendly method. Ideal for developers seeking to optimize performance by preloading data, ensuring faster access and smoother operation in their applications. `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.
override GetDefaultOptions(object[])	Retrieve the default options effortlessly with this user-friendly method. Perfect for developers seeking quick access to the default settings or configurations associated with an object, ensuring efficient customization and streamlined workflow.
override 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.
override GetSerializedStream(ImageOptionsBase, Rectangle, out int)	Converts to aps.
RemoveBackground()	Removes the background.
RemoveBackground(RemoveBackgroundSettings)	Removes the background.
virtual RemoveMetadata()	Removes metadata.
Resize(int, int)	Resizes the image. The default NearestNeighbourResample is used.
override Resize(int, int, ImageResizeSettings)	Resizes the image.
override Resize(int, int, ResizeType)	Effortlessly resize the image to desired dimensions with this intuitive method. Perfect for developers seeking to adjust the size of images dynamically, ensuring they fit the layout or requirements of their applications seamlessly.
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)	Adjust the orientation of the image by rotating, flipping, or applying both operations with this versatile method. Perfect for developers seeking to customize image orientation dynamically, ensuring optimal presentation or alignment in their applications.
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)	Customize the color palette of the image with this intuitive method. Ideal for developers seeking to apply specific color schemes or adjustments dynamically, ensuring precise control over the visual appearance of their images.

Examples

The following example shows how to cache all pages of a CDR image.

[C#]

string dir = "c:\\temp\\";

// Load an image from a CDR file.
using (Aspose.Imaging.FileFormats.Cdr.CdrImage image = (Aspose.Imaging.FileFormats.Cdr.CdrImage)Aspose.Imaging.Image.Load(dir + "sample.cdr"))
{
    // This call caches only the default page.
    image.CacheData();

    // Cache all pages so that no additional data loading will be performed from the underlying data stream.
    foreach (Aspose.Imaging.FileFormats.Cdr.CdrImagePage page in image.Pages)
    {
        page.CacheData();
    }
}
