After you do pdf_show_boxed() for the one color, do this: $textx = pdf_get_value($pdf, 'textx', 0); $texty = pdf_get_value($pdf, 'texty', 0); Now you know where PDFlib "left off" for the last word of that color. You can begin again at that point with a new color. Rinse. Repeat. It's probably going to be a pain to finish off a line, and then do a large chunk of text after that, but it's totally do-able. Note that pdf_show_boxed returns all the text that didn't "fit" -- so if you do this with boxes that are one line, and just keep doing that line after line, interspersing with the colored text and using the pdf_get_value() above, this is totally do-able, if somewhat tedious. If the colored text is "rare" enough, it might be worth doing something like: 1. text up to next colored text 2. pdf_get_value() 3. colored text 4. pdf_get_value() 5. one_line box size for pdf_show_boxed, returns rest of text 6. GOTO 1. particularly if you have huge texts and need performance to not loop through it one line at a time for ALL of it. On the plus side, pdflib, in my experience, tends to generate VERY small and compact PDF output, so the bandwidth is as cheap as it can be... YMMV -- Some people have a "gift" link here.
