`Ok, according to the PDFlib docs,
bpc - only for imagetype raw (required in this case). The number of bits per component. Must be 1,2,4 or 8
components - only for imagetype raw (required in this case). The number of image components. Must be 1, 3 or 4.
Read the docs (page 171) for a full list of params I assume are used for the last argument.`

`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:
> from rp@pdflib.com
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
memory.`

`a quick example:
$pdfimage = pdf_open_image_file($pdf, "jpeg", "test.jpg");
pdf_place_image($pdf, $pdfimage, 10, 10, 0.6);
...
pdf_close etc..`

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.
