PDFlib & PHP - (9) Formatting - Wrap Image

Yo! I need to wrap an image w/ text. Here is how it is done in PHP with PDFlib. Get your own, bigger chunk o' lorem if you want. It was five paragraphs of lorem ipsum, but it was an ugly paste, so I cut a few out. Also, the image is from the web and may not be at that address one day.

Using Matchbox optlist of optlist of... to Wrap Image

# wrap image with text using the "usematchbox" option

#  of fit_image() - [available in Java only @Cookbook].

$file_name = "blog_9.pdf";

# number reflect an A4 sized document.

$doc_width = 595;

$doc_height = 842;
