If you just need to display the file in the default application assigned to it you can use the run command with the file name. Windows will then launch the viewing app which then displays the file.

HELLO
Here is the code to scan tiff files.you can have a look:
using System.IO;
using System.Drawing.Printing;
using RasterEdge.Imaging;
using RasterEdge.Imaging.Processing;
using RasterEdge.Imaging.MultipageTiff;

RasterEdgeImaging TIFF = new RasterEdgeImaging();
public class AcquisitionClass
{
private bool AcquireCanceled;
private Acquisition Acquisition = new Acquisition(this);
public void Scan()
{
AcquireCanceled = false;
Acquisition.AcquireCanceled += new EventHandler(OnAcquireCanceled);
Acquisition.AcquireFinished += new EventHandler(OnAcquireFinished);
Acquisition.ImageAcquired += new ImageAcquiredEventHandler(OnImageAcquired);
Device activeDevice = Acquisition.ShowSelectSource();
activeDevice.Acquire();
}
private void OnImageAcquired(object sender, AcquireEventArgs e)
{
if (e.Image != null)
{
TiffEncoder enc = new TiffEncoder(TiffCompression.Default, true);
FileStream fs = new FileStream("1.tif",FileMode.OpenOrCreate, FileAccess.ReadWrite);
enc.Save(fs, AtalaImage.FromBitmap(e.Image), null);
fs.Close();
}
}
private void OnAcquireCanceled(object sender, EventArgs e)
{
AcquireCanceled = true;
}
private void OnAcquireFinished(object sender, EventArgs e)
{
if (AcquireCanceled)
return;
TiffImageCollection col = new TiffImageCollection();
TiffDecoder dec = new TiffDecoder();
FileStream fs = new FileStream("1.tif", FileMode.Open, FileAccess.Read);
int frameCount = dec.GetFrameCount(fs);
fs.Close();
for(int i=0; i< frameCount; i++)
col.Add(new TiffImage("1.tif", i, TiffCompressionType.Auto));

FileStream outStream = new FileStream("1.tiff", FileMode.OpenOrCreate, FileAccess.ReadWrite);
TiffEncoder enc = new TiffEncoder();
enc.Save(outStream, col, null);
}
}

This is .Net code and isn't applicable to PowerBuilder unless exposed via COM.
