GetFileFormat

Image.GetFileFormat method (1 of 2)

Gets the file format.

public static FileFormat GetFileFormat(string filePath)
ParameterTypeDescription
filePathStringThe file path.

Return Value

The determined file format.

Remarks

The file format determined does not mean that the specified image may be loaded. Use one of the CanLoad method overloads to determine whether file may be loaded.

Examples

This example shows how to determine the image format without loading the entire image from a file.

[C#]

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

// Use an absolute path to the file
Aspose.Imaging.FileFormat format = Aspose.Imaging.Image.GetFileFormat(dir + "sample.gif");
System.Console.WriteLine("The file format is {0}", format);

Image.GetFileFormat method (2 of 2)

Gets the file format.

public static FileFormat GetFileFormat(Stream stream)
ParameterTypeDescription
streamStreamThe stream.

Return Value

The determined file format.

Remarks

The file format determined does not mean that the specified image may be loaded. Use one of the CanLoad method overloads to determine whether stream may be loaded.

Examples

This example shows how to determine the image format without loading the entire image from a file stream.

[C#]

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

// Use a file stream
using (System.IO.FileStream stream = System.IO.File.OpenRead(dir + "sample.bmp"))
{
    Aspose.Imaging.FileFormat format = Aspose.Imaging.Image.GetFileFormat(stream);
    System.Console.WriteLine("The file format is {0}", format);
}

// The following data is not a valid image stream, so GetFileFormat returns FileFormat.Undefined.
byte[] imageData = new byte[] { 0, 0, 0, 0, 0, 0, 0, 0 };
using (System.IO.MemoryStream stream = new System.IO.MemoryStream(imageData))
{
    Aspose.Imaging.FileFormat format = Aspose.Imaging.Image.GetFileFormat(stream);
    System.Console.WriteLine("The file format is {0}", format);
}
