Aspose.Imaging提供了丰富的API用于转换图片为多种文件格式，可以让开发人员可以创建、编辑、画图、转换图像的图像处库，提供了一些开发平台原有功能基础之上的一些新特性。它独立于其他应用程序， Aspose.Imaging 允许你在不安装PhotoShop的情况下保存PSD格式等。

下面的事例介绍了如何加载一个GIF文件，并且转换为BMP, JPEG, PNG 和TIFF，其他格式之间在转换使用上也跟该事例差不多，具体代码如下：

[C#]
//Load an existing image (of type Gif) in an instance of the Image class
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(@"C:\sample.gif"))
{
    //Export to BMP file format using the default options
    image.Save(@"C:\output.bmp", new Aspose.Imaging.ImageOptions.BmpOptions());

    //Export to JPEG file format using the default options
    image.Save(@"C:\output.jpeg", new Aspose.Imaging.ImageOptions.JpegOptions());

    //Export to PNG file format using the default options
    image.Save(@"C:\output.png", new Aspose.Imaging.ImageOptions.PngOptions());

    //Export to TIFF file format using the default options
    image.Save(@"c:\output.tiff", new Aspose.Imaging.ImageOptions.TiffOptions());
}
 
[Visual Basic]
'Load an existing image (of type Gif) in an instance of the Image class
Using image As Aspose.Imaging.Image = Aspose.Imaging.Image.Load("C:\sample.gif")
 'Export to BMP file format using the default options
 image.Save("C:\output.bmp", New Aspose.Imaging.ImageOptions.BmpOptions())

 'Export to JPEG file format using the default options
 image.Save("C:\output.jpeg", New Aspose.Imaging.ImageOptions.JpegOptions())

 'Export to PNG file format using the default options
 image.Save("C:\output.png", New Aspose.Imaging.ImageOptions.PngOptions())

 'Export to TIFF file format using the default options
 image.Save("c:\output.tiff", New Aspose.Imaging.ImageOptions.TiffOptions())
End Using
