This is a VB.NET programming sample code to convert PDF file to GIF image.

  1. Create a new ImageOutputOption object for converted GIF images
  2. Set image type to GIF ImageType.GIF
  3. Set GIF image color, zoom, and resolution values.
  4. Create a PDFDocument object with an existing PDF file loaded
  5. Get the first page object PDFPage of the PDF document
  6. Use the method PDFPage.ConvertToImage() to convert the first page of PDF file to gif image with options applied



Dim inputFilePath As String = "C:\1.pdf"
Dim outputFilePath As String = "C:\output.gif"

Dim options As ImageOutputOption = New ImageOutputOption()
' Set output image type.
options.Type = ImageType.GIF
' Output image Is grayscale.
options.Color = ColorType.Gray
' Set zoom value to 2F. Use more pixels to render the page.
options.Zoom = 2.0F
' Set resolution value in the PNG file to 300 dpi.
options.Resolution = 300

' Open file And get the target page
Dim doc As PDFDocument = New PDFDocument(inputFilePath)
Dim page As PDFPage = doc.GetPage(0)
' Convert page to a GIF image
page.ConvertToImage(options, outputFilePath)






VB.NET: How to convert the first PDF page to image file to preview


The steps and VB.NET source code below will show how to convert the first PDF page to preview in VB.NET application.

  1. Create a new ImageOutputOption object for converted PNG image
  2. Set image type to Bitmap ImageType.PNG
  3. Set image color to ColorType.Color
  4. Set PDF page zoom is 0.25F. The preview image area size is 25% of the original PDF page. You can choose to other values, if you need.
  5. Set PNG image resolution to 600 dpi. You can choose larger resolution for printing.
  6. Create a PDFDocument object with PDF file loaded
  7. Get the first page object PDFPage of the PDF document
  8. Use the method PDFPage.ConvertToImage() to convert the first page of PDF file to png image file



Dim inputFilePath As String = "C:\1.pdf"
