This article would introduce a detail method to split the tiff image and draw to pdf document. The below picture show the effect of splitting tiff image and drawing to pdf document:

Split tiff image and Convert to pdf document

The main steps of the method are:

One: Split multi-page TIFF file to multiple frames

  • Load a multipage Tiff.
  • Use Image.GetFrameCount method to get the number of frames of tiff Image.
  • Initialize a new instance of Guid to save the dimension from tiff image.
  • Using Guid to initialize a new instance of the System.Drawing.Imaging.FrameDimension class.
  • Iterate over the Tiff Frame Collection and save them to Image array.

Two: Draw image to PDF

  • Initialize a new instance of Spire.Pdf.PdfDocument.
  • Iterate over the image array.
  • Use Spire.Pdf.PdfPageBase.Canvas.DrawImage method to draw image into page with the specified coordinates and image size.
