| 本文介紹下,使用php代碼在圖片上加浮水印或文字的例子,有需要的朋友參考下吧。 php浮水印代碼,如下: "; //Echo $height_image; //exit; $font_size = 88; //putenv("GDFONTPATH=C:/WINDOWS/Fonts"); $fontname = "ARIAL.TTF"; do { $font_size--; $bbox = imagettfbbox($font_size,0,$fontname,$button_text); $right_text = $bbox[2]; $left_text = $bbox[0]; $width_text = $right_text - $left_text; $height_text = abs($bbox[7] - $bbox[1]);}while($font_size > 8 && ($height_text > $height_image_wo_margins || $width_text > $width_image_wo_margins)); $text_x = $width_image/2.0 - $width_text/2.0;$text_y = $height_image/2.0 - $height_text/2.0; if($left_text < 0){ $text_x += abs($left_text);} $above_line_text = abs($bbox[7]);$text_y += $above_line_text; $text_y -= 2; $white = imagecolorallocate($image,255,255,255); imagettftext($image,$font_size,0,$text_x,$text_y,$white,$fontname,$button_text); imagepng($image);imagedestroy($image);?>以上代碼實現:在一個按鈕圖片上面添加一個click here的英文字。 個人覺得,是一個比較簡單的學習php圖片浮水印的例子,適合新手朋友參考。 |
