Examples
Sample code using the cfpdf tag

Creates a JPG thumbnail from a PDF file

cfpdf(
    action="thumbnail",
    source=expandPath( "./myFile.pdf" ),
    destination=expandPath( "./thumbnails/"),
    resolution="high",
    overwrite="yes",
    pages="1",
    scale="75",
    transparent="no"
);

Expected Result: Creates a file called myFile_page_1.jpg in the /thumbnails/ directory
