Re:GD, write text on image

Hi Cam and Sven, Thank you very much for your advises. I confess, I parallelly asked this question on another list... There I was given the tip to write the text in black even 8 times and once in white. The random pixel-search is also an accaptable approach. I'll surely try both. Server load is no problem since I'm not offering this service to customers but use it to process my own pictures in one approach.

This will give you a crude drop shadow effect and will be readable over virtually any background colour or mix of colours. >> -----Ursprüngliche Nachricht----- >> Von: Bernhard Döbler [SMTP:programmer@bardware.de] >> Gesendet am: Mittwoch, 23.
