The IsTga method is a static method of the Bitmap class in the Sandbox namespace. It is used to determine whether a given byte array represents a TGA (Targa) image file. This method analyzes the provided byte array to check for the specific characteristics of a TGA file format.

To use the IsTga method, you need to pass a byte array that you suspect might be a TGA image. The method will return a boolean value indicating whether the byte array is indeed a TGA file.

Example usage:

byte[] imageData = ...; // Load or receive your image data as a byte array
bool isTga = Bitmap.IsTga(imageData);
if (isTga)
{
    // Proceed with TGA-specific processing
}
else
{
    // Handle non-TGA data
}
