With
GhostScript (
http://sourceforge.net/projects/ghostscript/) &
GFL SDK/GFLAx (
http://perso.orange.fr/pierre.g/xnview/engfl.html) which is free you can convert PDF files to other image formats. I'm sure that GFL works with MS Visual C# Express and MS VB 2005, which are also free. The code listing below will convert the first 6 pages for FAQ.PDF to png files using vbscript. You can test it out by saving the code into a file called test.vbs and then double click on it run it.
Code:
option explicit
displaypage
sub displaypage
const AX_PNG = 3
const numofpages = 6
Dim File, ThumbNail, imagepath, i
Set ThumbNail = createobject("GflAx.GflAx")
imagepath = "c:\test.png"
File = "c:\FAQ.pdf"
With ThumbNail
for i = 1 to numofpages
.EpsDpi = 72
.Page = i
.LoadBitmap File
.Saveformat = AX_PNG
.saveBitmap replace(imagepath,"test","test" & i)
next
end with
set ThumbNail=nothing
end sub
