note 8352 deleted from ref.cpdf by jimw

Example 1 is broken since, units being left at their defaults, the script tries to write text wwwaaayyy out of the A4 page is sets up. To better illustrate the point, here is a proposed new version: <?php /* define no. of points in a millimeter */ define("PPM", 2.83464566929); $pdf = cpdf_open(0); /* Set page size to A4 (_MUST_ use points). */ /* Set unit to millimeters for computing object */ /* coordinates in the rest of the script. */ cpdf_page_init($pdf, 1, 0, 595, 842, PPM); cpdf_add_outline($pdf, 0, 0, 0, 1, "Page 1"); cpdf_begin_text($pdf); /* Note: font size (30) _MUST_ always be given in points. */ cpdf_set_font($pdf, "Times-Roman", 30, "WinAnsiEncoding"); cpdf_set_text_rendering($pdf, 1); /* Lower left coordinates for the string _MUST_ now */ /* be given in millimeters, origin being the lower left */ /* corner of the page. */ cpdf_text($pdf, "Times Roman outlined", 100, 100); cpdf_end_text($pdf); /* Coordinates for segment end points _MUST_ now */ /* be given in millimeters, origin being the lower left */ /* corner of the page. */ cpdf_moveto($pdf, 1000, 950); cpdf_lineto($pdf, 1985, 950); cpdf_stroke($pdf); cpdf_finalize($pdf); Header("Content-Type: application/pdf"); cpdf_output_buffer($pdf); cpdf_close($pdf); ?> Beware though that, when using the Acrobat plug-in in Win32, you will be able to see the correct output _ONLY_ under Netscape, MSIE doesn't show anything (well for the clock example at least, refreshing the page once does the trick - go figure)! I found out MSIE _REQUIRES_ a correctly set Content-Length header to be sent beside Content-Type to correctly display PDFs... this is a nuisance, since the PHP ClibPDF functions don't include a way to get the length of a document when you create it in memory, and you have to: 1) write the document to a file, get the filelength and fopen+fpassthru it after having sent the Content-Length header; 2) e.g. fopen a "secondary" PHP script that creates the PDF in memory, "cpdf_output_buffer"s it to the "primary" script that reads to EOF into a string, "strlen"s it and "print"s it after setting the required header. Both these "hacks" work, even though I'd much prefer to have an additional function to get the buffer's length (hint, hint :) ); I also tried the new (as of PHP 4.0.2) output_control functions (ob_start, etc.) to no avail - cpdf_output_buffer apparently is not similar enough to echo. Hope this helps Massimo
