The following example saves the contents of an ImageWell to a temporary file on disk and then reads it into a BinaryStream for storage in a database. The property f as FolderItem is a property of the window.

Var imageData As String
Var bs As BinaryStream
Var f As FolderItem
If ImageWell1.Image <> Nil Then
// Get a temporary file to save the image to
If Picture.IsExportFormatSupported(Picture.FormatJPEG) Then
f = SpecialFolder.Temporary.Child("TempImage.jpg")

// Save the image out to the file
ImageWell1.Image.Save(f, Picture.Formats.JPEG)
End If

// Open the file as a BinaryStream and read the data in
bs = BinaryStream.Open(f, False)
If bs <> Nil Then
imageData = bs.Read(bs.Length)
End If

// delete the temporary file if it exists
If f.Exists Then
End If
End If
