Read the docs (page 171) for a full list of params I assume are used for the last argument.

PDF_open_image — Utilizează datele imaginii [învechit]
Utilizează datele imaginii din diferite surse de date.
Această funcție este învechită începând cu PDFlib versiunea 5, utilizați fișiere virtuale și PDF_load_image() în loc.
If you want to open a TIFF image, you have to use pdf_open_image_file(). If you want to open a TIFF image from memory, you'll have to wait until version 5. I gleaned this from the PDFlib folks themselves:

The only way to open TIFF with PDFlib 4 is to open it from
file. But in PDFlib 5 (http://www.pdflib.com/beta/) we add
a virtual file system, so you can easy open a file from
if you ahve pdflib v4 or higher, you may also use TIFF images, by specifying 'tiff' in the image type.
checked the pdflib documentation, tried it out, it works.
a quick example:
$pdfimage = pdf_open_image_file($pdf, "jpeg", "test.jpg");
pdf_place_image($pdf, $pdfimage, 10, 10, 0.6);

and Thomas Merz answered:
Nope. Unfortunately PDF supports _nearly_ everything needed
to decode GIFs internally (as with JPEG), but some minor
feature is missing. It seems Adobe also realized this --
they added the missing link in PostScript 3, so chances are
it will appear in PDF 1.4 or something...
Since the PDF_open_image() interface is meant for dumping
the image data to the PDF without any further interpretation,
it can't support GIF.
For good and easy to understand examples on images in PDFs go to
(It's in german, but the sources alone will be a great help and inspiration :-))
