| virtual HeightF { get; } | Gets the object height, in inches. |
| InterruptMonitor { get; set; } | Gets or sets the interrupt monitor. |
| override IsCached { get; } | Effortlessly determine whether the object’s data is currently cached, eliminating the need for data reading. Ideal for developers seeking to optimize performance by leveraging cached data efficiently, ensuring faster access to object information. |
| override PageCount { get; } | Effortlessly retrieve or update the total page count of the image with this intuitive property. Ideal for developers seeking to manage multi-page images dynamically, ensuring efficient navigation and manipulation of image content. |
| virtual 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. |
| override Pages { get; } | Retrieve the pages of the image seamlessly with this intuitive property. Ideal for developers seeking to access and manipulate individual pages within multi-page images, ensuring efficient navigation and processing. |
| 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 |
|---|---|
| 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. |
| override Crop(Rectangle) | Crops the specified rectangle. |
| virtual Crop(int, int, int, int) | Crop image with shifts. |
| 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. |
| override RemoveBackground() | Removes the background. |
| override 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) | 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. |
| override Rotate(float) | Rotate image around the center. |
| override 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. |
| 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();
}
}
