Are you whanting to give an example, or requesting an example?

You are not exactly clear!

I need an example to convert pdf to tiff with user specified resolution with out using third party packages i.e, i need to convert by using the acrobat plugin alone.

IM does not use acrobat to convert PDF. It uses Ghostscript.

thanks for ur reply.

am using the Javascript object to convert to tiff from pdf.
code is,

Private Sub ConvertToTiff_Click()
Dim jso As Object
Dim pdDoc As Acrobat.CAcroPDDoc
Set pdDoc = CreateObject("AcroExch.PDDoc")

'This uses the Adobe Acrobat API to save the PDF as TIF
If FileName <> "" Then
If pdDoc.Open(FileName) Then
Set jso = pdDoc.GetJSObject
jso.SaveAs ImageFileName + "tif", "com.adobe.acrobat.tiff"

pdDoc.Close
End If

Set jso = Nothing
' This kills the Acrobat.exe process
Set pdDoc = Nothing
MsgBox ("successfully converted!")
Else
MsgBox ("Select PDF File!")
End If
End Sub
//////////
The output tiff resolution for one pdf to another i.e,one tiff resolution is 150 dpi and another is 300 dpi. but i have to produce the tiff with my specified resolution.Is any code can be added to this ,to make tiff with my resolution?

[anthony]

Tricky. I don't work with TIFF and what I do know is hersay. By I understand photoshop (the authority for TIFF) saves resolution in a special profile, separate to the normal resolution handling. IM probably will save in the normal metadata, while photoshop uses the profiled meta-data. IM may not be of much help.

TIFF is a horrible image format, other than photoshop, all other programs only handle sub-sets of the full convoluted TIFF format.

All I can suggest try various things like

Code: Select all

   convert image  -density 300x300 image_im300.tif

and see is that does the trick. Also try other utilities. Sorry not much help.

In that case I suggest you start a new disscussion thread in Bugs Forum, with the command line that you tried, a link to the bad TIFF file produced, and a link to a good tiff file that your 3rd party software produced.
