TIFF Rendering

Users who are going to convert TIFF file to PNG or any other image or document format need to render and transform the whole embedded TIFF document or certain input page to REImage object first by using following demo methods, which are compatible with any .NET Framework developing environment, including VB.NET (illustrated in this page), Visual C#.NET, ASP.NET and .NET Windows Forms.
'APIs for rendering TIFF to get a REImage collection
Private Function GetPage(pageIdx As Integer) As BasePage Implements TIFFDocument.GetPage
End Function
Private Function toImage() As BaseImage Implements TIFFPage.toImage
End Function
Private Function toImage(width As Integer, height As Integer) As BaseImage Implements TIFFPage.toImage
End Function
Private Sub New(imagesource As List(Of REImage))
End Sub

Image Converting

Please directly use API below to convert the rendered TIFF image to any supportable image or document file with VB.NET programming code, such as Png, Jpeg, Bmp, Gif, Svg and Pdf.
' API for converting TIFF file to PNG
Private Sub Convert(s As Stream, format As ImageFormat) Implements REImage.Convert
End Sub
Demo Code
Whether you are a professional VB programmer or an amateur, following VB sample code will fit your needs best for its simplicity and high flexibility.
As you can see, besides mature TIFF-to-PNG image converting methods, we also provide the robust image file page handling solutions like "doc.GetPage" to help users locate the target TIFF file page(s) that need(s) to be converted.
