Hello Brand,
Sorry for my long silence.
Here it is the sample code which allows to do what you want.
static void Split(String fileName)
{
PixImageStorage inFile = PixImageStorage.Open(fileName);
int counter = 0;
foreach(PixImage img in inFile.Images)
{
PixImageStorage.Save(img, PixFileType.Tiff,
counter.ToString() + ".tif",
img.StorageInformation.CompressionSettings,
OpenFileMode.CreateAlways);
counter++;
}
}
