ClibPDF lets you create PDF documents with PHP. ClibPDF functionality
and API are similar to PDFlib.
This documentation should be read alongside the ClibPDF manual since it
explains the library in much greater detail.
Many functions in the native ClibPDF and the PHP module, as well
as in PDFlib, have the same name.
All functions except for cpdf_open() take the
handle for the document as their first parameter.
Currently this handle is not used internally since ClibPDF does
not support the creation of several PDF documents at the same time.
Actually, you should not even try it, the results are unpredictable. I
can't oversee what the consequences in a multi threaded environment
are. According to the author of ClibPDF this will change in one of
the next releases (current version when this was written is 1.10).
If you need this functionality use the pdflib module.
A nice feature of ClibPDF (and PDFlib) is the ability to create the pdf
document completely in memory without using temporary files. It
also provides the ability to pass coordinates in a predefined unit
length. (This feature can also be simulated by
pdf_translate() when using the PDFlib functions.)
Another nice feature of ClibPDF is the fact that any page can be modified
at any time even if a new page has been already opened. The function
cpdf_set_current_page() allows to leave the current
page and presume modifying an other page.
Most of the functions are fairly easy to use. The most difficult part
is probably creating a very simple PDF document at all. The following
example should help you to get started. It creates a document
with one page. The page contains the text "Times-Roman" in an
outlined 30pt font. The text is underlined.
This extension has been moved to the PECL repository and is no longer bundled with
PHP as of PHP 5.1.0.
If you're interested in alternative free PDF generators that do not
utilize external PDF libraries, see
this related FAQ.
In order to use the ClibPDF functions you need to install the ClibPDF
package. It is available for download from
FastIO, but requires that you purchase a license for commercial
use. PHP requires that you use cpdflib >= 2.
The development of ClibPDF library has been discontinued thus FastIO
website would be most probably inaccessible.
To get these functions to work, you have to compile PHP with
--with-cpdflib[=DIR]. DIR is the cpdflib
install directory, defaults to /usr. In addition you
can specify the jpeg library and the tiff library for ClibPDF to use. To do
so add to your configure line the options
