Can this be done in PureBasic? I need to basically convert PDF to TIF in PB.

I think you possibly need a GhostScript license to do it. It's an unusual requirement........
Maybe DIY, here's the PDF spec: http://www.adobe.com/devnet/pdf/pdf_reference.html

using pdf2image (from www.verypdf.com), it can be launched from a command line. then using
RunProgram("pdf2img.exe" -i file1.pdf -o file1.tiff -b 1 -c lzw -r 300")
you can get what you want, but it's not free

I think you can use xpdf, it's free.

Xpdf is only free if you are going to use it as-is without modification. Otherwise you have to either distribute your own app under GPL, or buy a commercial license for Xpdf.

Another possibility would be to run a script that opens the PDF in Adobe Reader, screen-capture each page, save as TIF. There is an AutoIt wrapper for PB: http://www.purebasic.fr/english/viewtop ... =5&t=49438

We are using a tool for this. It is QuickPDF library. It costs money, but it is very powerfull.

http://www.quickpdflibrary.com/

It costs minimum $349.00 (single developer licence), but there are no runtime licences needed. It is definitely worth the price, because it saved me so many days and gives professional features to our product...

There is also a free version with limited functionality. Maybe it is enough for your needs?

That certainly looks like a very nice lib. The lite version though is not as good as PurePDF.

Thanks everyone for all the input

I like this method the best honestly. It provides what I need the quickets without having to use libraries to write my own converter. I wish they would let me use the command line version in the trial. When I try it opens the app asking me to register first. Probobly will buy this once I get go ahed from my boss. In your command line example you have this
I assume
-b = bits per pixel
-c = compression (I hope CITTFAX4 is supported... im sure it is)
-r = DPI resolution of output

am i correct? the website and trial application do not give help on command line parameters. Thank you.

here you have the meaning of all parameters:

Command Line Usage:

Example:
pdf2img -i C:\input.pdf -o C:\output.tif
pdf2img -m -i C:\input.pdf -o C:\output.tif
pdf2img -c lzw -i C:\input.pdf -o C:\output.tif
pdf2img -q 80 -i C:\input.pdf -o C:\output.jpg
pdf2img -b 4 -i C:\input.pdf -o C:\output.tif

Please notice, if your input pdf's filename or output tiff's filename contain space(s), you must use quotation mark to include them, for example,

C:\>pdf2img "C:\123 456.pdf" "C:\my test\aaa.tif"

im using Ghostscript without any problems, here´s the code :
