1. Download the software
You may have already downloaded the Xpdf
tools while watching one of my earlier videos in the series, but there has since been an upgrade from Version 3 to Version 4 and there is a new download site:
Visit that site and download the pre-compiled Windows binary ZIP archive, then unzip it.
2. Locate the documentation folder for the Xpdf utilities
Go to the folder where you unzipped the downloaded ZIP file and find the doc
3. Read the documentation for the PDFtoPPM tool
Go into the doc
folder and find the plain text file called pdftoppm.txt
Open it with any text editor, such as Notepad, and read it. This is the documentation for the PDFtoPPM
4. Set up a test folder
Create a test folder.
from the unzipped bin32
folder into your test folder.
Copy a sample PDF file into your test folder, preferably one with numerous pages.
5. Set up a command prompt for testing
Open a command prompt window.
Navigate to your test folder.
Issue a DIR command in the command prompt to be sure that only two files are in it - the PDFtoPPM executable and the sample PDF file.
6. Run the PDFtoPPM utility to create color images
Issue the following command in the command prompt:
pdftoppm TestFileName.pdf color
If you receive the following error messages, ignore them:
Config Error: No display font for 'Symbol'
Config Error: No display font for 'ZapfDingbats'
7. Run the PDFtoPPM utility to create grayscale and monochrome images
Issue the following commands in the command prompt:
pdftoppm -gray TestFileName.pdf gray
pdftoppm -mono TestFileName.pdf mono
8. Open the created images
Open the PPM, PGM, and PBM files to make sure that they were created correctly.
