virtual UsePalette { get; }	Gets a value indicating whether the image palette is used.
override Width { get; }	Retrieves the width of the image, indicating the horizontal dimension in pixels. This property provides essential information about the image’s size, enabling precise rendering, manipulation, and analysis of image data.
virtual WidthF { get; }	Gets the object width, in inches.

Methods

Name	Description
override 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.
override GetDefaultOptions(object[])	Retrieves the default options configured for the image, providing a convenient way to access and modify the default settings. This property ensures consistency in operations by offering predefined settings that align with common use cases, simplifying the development process.
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)	Adjusts the dimensions of the image according to specified width, height, and resize settings. This method provides flexibility in resizing images while maintaining desired proportions and adhering to defined resize configurations, ensuring accurate adjustment of image dimensions to meet specific requirements or display criteria.
override Resize(int, int, ResizeType)	This method resizes the image, adjusting both width and height based on the specified dimensions and resize type. It offers a comprehensive approach to resizing, allowing for precise adjustments while maintaining image quality and integrity. By incorporating the resize type parameter, users can choose from various resizing algorithms or methods to achieve optimal results for different use cases or preferences.
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.

override RotateFlip(RotateFlipType)	This method provides functionality to rotate, flip, or perform both operations simultaneously on the image. It allows users to manipulate the orientation of the image according to their specific requirements. With support for rotation angles and flip directions, it offers flexibility in transforming the image to desired orientations or orientations.
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.

Examples

The following code snippet demonstrates how to convert an OTG image to PDF and other image formats.

[C#]

string dir = "c:\\aspose.imaging\\issues\\net\\3567\\";
string inputFilePath = dir + "VariousObjectsMultiPage.otg";
Aspose.Imaging.ImageOptionsBase[] options = { new Aspose.Imaging.ImageOptions.PngOptions(), new Aspose.Imaging.ImageOptions.PdfOptions() };
foreach (Aspose.Imaging.ImageOptionsBase saveOptions in options)
{
    string extension = saveOptions is Aspose.Imaging.ImageOptions.PngOptions ? ".png" : ".pdf";
    using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFilePath))
    {
        Aspose.Imaging.ImageOptions.OtgRasterizationOptions otgRasterizationOptions = new Aspose.Imaging.ImageOptions.OtgRasterizationOptions();
        otgRasterizationOptions.PageSize = image.Size;
        saveOptions.VectorRasterizationOptions = otgRasterizationOptions;

        image.Save(inputFilePath + extension, saveOptions);
    }
