For work needs, I wrote a simple PHP image watermarking function.

  1. /*
  2. Image watermarking function
  3. $imag_url is the path to the image to be watermarked
  4. $str is the string to be added to the picture
  5. $route is the storage path after watermarking
  6. */
  7. function watermark($ imag_url,$str,$route) {
  8. $type_array=explode(.,$imag_url);
  9. $imag_type=$type_array[count($type_array)-1];
  10. switch($imag_type) {
  11. case gif: $img=imagecreatefromgif($imag_url); break;
  12. case jpeg: $img=imagecreatefromjpeg($imag_url); break;
  13. case jpg: $img=imagecreatefromjpeg($imag_url); break;
  14. case png: $img=imagecreatefrompng($imag_url); break;
  15. default: $im g= imagecreatefromgif($imag_url); break;
  16. }
  17. //Font color
  18. $gray = imagecolorallocate($img, 235, 235, 235);
  19. $pink = imagecolorallocate($img, 255, 128, 255);
  20. /* $fontfile The path of the font, depending on the operating system, can be simhei.ttf (black body), SIMKAI.TTF( Chinese fonts supported by GD*/
  21. $fontfile = "C:WINDOWSFontsSIMHEI.TTF";
  22. $str = iconv(GB2312,UTF-8,$str); /*Convert gb2312 character set to UTF-8 characters*/
  23. imagettftext($img, 30,0, 0, 200, $pink, $fontfile, $str);
  24. /* Add Chinese watermark*/
  25. imagepng($img,$route);
  26. imagedestroy($img);
  27. }
  28. ?>

I hope the above function can be useful to everyone.
