Question

内のテキストを追加します。

私はこれを試してみました：

//create required instances... 
$Imagine = new \Imagine\Gd\Imagine(); 
$Palette = new \Imagine\Image\Palette\RGB(); 
//Background color of the upcomming image basend on settings passed by user... 
$BackgroundColor = $Palette->color('fff', 0); 
//...some other code... 
$TextColor = $Palette->color('#000', 100); 
//create an ImageBox for upcomming image based on given width and height 
$ImageBox = new \Imagine\Image\Box(300, 300); 
//get center X|Y coordinates for ImageBox 
$ImageCenterPosition = new \Imagine\Image\Point\Center($ImageBox); 
//create Text Object with font-family, font-size and color from settgins 
$TextFont = new \Imagine\Gd\Font(BASE_PATH . "/public/assets/plugins/font-awesome/fonts/fontawesome-webfont.ttf" , 13, $TextColor); 
//create a Box (dimensions) based on font and given string... 
$TextBox = $TextFont->box("test texte"); 
//get center X|Y coordinates for the box containing the text 
$TextCenterPosition = new \Imagine\Image\Point\Center($TextBox); 
//calculate center X|Y coordanates from ImageBox center coordanates and FontBox center coordanates 
$CenteredTextPosition = new \Imagine\Image\Point($ImageCenterPosition->getX() - $TextCenterPosition->getX(), $ImageCenterPosition->getY() - $TextCenterPosition->getY()); 
//create an image with ImageBox dimensions and BackgroundColor 
$_img_ = $Imagine->create($ImageBox, $BackgroundColor); 
//now draw the text... 
$_img_->draw()->text("test texte 222", $TextFont, $CenteredTextPosition); 
$_img_->save($newName); 

私は君たちの一つが解決を手伝うことができると思います。

私はそれを修正、私はPHPの機能を使用：

public function saveImageWithText($source_file, $sText = null, $font = null) 
    { 
     if (!file_exists($source_file)) 
      throw new Exception('De afbeeldingbestand dat u heeft aangegeven is niet gevonden.'); 

     $allowedExtensions = array(
      1, // [] gif 
      2, // [] jpg 
      3, // [] png 
      6 // [] bmp 
     ); 

     // Copy and resample the imag 
     list($width, $height, $extension) = getimagesize($source_file); 

     if (!in_array($extension, $allowedExtensions)) 
      throw new Exception('De afbeelding extentie wordt niet odersteund.'); 

     switch ($extension) { 
      case 1 : 
       $image = imageCreateFromGif($source_file); 
       break; 
      case 2 : 
       $image = imageCreateFromJpeg($source_file); 
       break; 
      case 3 : 
       $image = imageCreateFromPng($source_file); 
       break; 
      case 6 : 
       $image = imageCreateFromBmp($source_file); 
       break; 
     } 

     $image_p = imagecreatetruecolor($width, $height); 
     imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width, $height); 

     // Prepare font size and colors 
     $text_color = imagecolorallocate($image_p, 0, 0, 0); 
     $bg_color = imagecolorallocate($image_p, 255, 255, 255); 
     $font_size = 20; 

     if(is_null($font)) 
      $font = BASE_PATH . '/public/assets/data/fonts/clear-sans.regular.ttf'; 

     if (!file_exists($font)) 
      throw new Exception('De fontbestand dat u heeft aangegeven is niet gevonden.'); 

     // Set the offset x and y for the text position 
     $offset_x = 5; 
     $offset_y = 50; 

     // Set text to be write on image 
     if(is_null($sText)) 
      $sText = "Foto opgenomen op : " . date("d-m-Y H:i"); 

     // Get the size of the text area 
     $dims = imagettfbbox($font_size, 0, $font, $sText); 

     $text_width = $dims[4] - $dims[6] + $offset_x; 
     $text_height = $dims[3] - $dims[5] + $offset_y; 

     // Add text background 
     imagefilledrectangle($image_p, 0, 0, $text_width + 10, $text_height, $bg_color); 

     // Add text 
     imagettftext($image_p, $font_size, 0, $offset_x, $offset_y, $text_color, $font, $sText); 

     // Save the picture 
     switch ($extension) { 
      case 1 : 
       imagegif($image_p, $source_file); 
       break; 
      case 2 : 
       imagejpeg($image_p, $source_file); 
       break; 
      case 3 : 
       imagepng($image_p, $source_file); 
       break; 
      case 6 : 
       imagepng($image_p, $source_file); 
       break; 
     } 

     // Clear 
     imagedestroy($image); 
     imagedestroy($image_p); 
    }
