Textures 
 
 Textures are one of the hardest text effects possible.  This is due to the fact that you need to know how to use a mask to create the texture. 
 
 <?php 
 function imagettftexttexture (& $im ,& $textureim ,$size ,$angle ,$x ,$y ,$fontfile ,$text )
 { 
     $width = imagesx ($im ); // Get the width of the image 
     $height = imagesy ($im ); // Get the height of the image 
     $buffer = imagecreate ($width ,$height ); // Create the buffer image 
     $tile_w = imagesx ($textureim ); // Get the width of the texture image 
     $tile_h = imagesy ($textureim ); // Get the height of the texture image 
     $fits_x = (int)( $im_w /$tile_w ); // Find out how many times it fits horizontally 
     $fits_y = (int)( $im_h /$tile_h ); // Find out how many times it fits vertically 
     for ( $i =0;$i <= $fits_x ;$i ++) { // Loop through every time (and another, for extra space) it fits horizontally 
         $x = (int)( $tile_w *$i ); // Change the X location based on where in the loop it is 
         for ( $i2 =0;$i2 <= $fits_y ;$i2 ++) { // Loop through every time it fits vertically 
             $y = (int)( $tile_h *$i2 ); // Change the Y location 
             $copy = imagecopy ($im ,$textureim ,$x ,$y ,0,0,$tile_w ,$tile_h ); // Copy the image to the X,Y location 
         }
     } 
     $pink = imagecolorclosest ($im ,255 ,0,255 ); // Create magic pink, a color commonly used for masks 
     $trans = imagecolortransparent ($im ,$pink ); // Make magic pink the transparent color 
     imagettftext ($im ,$size ,$angle ,$x ,$y ,- $pink ,$fontfile ,$text ); // Draw text over magic pink without aliasing 
     imagecopy ($buffer ,$im ,0,0,0,0,$width ,$height ); // Copy the main image onto the buffer 
     imagecopy ($im ,$buffer ,0,0,0,0,$width ,$height ); // Copy the buffer back onto the main image 
     imagedestroy ($buffer ); // Destroy the buffer
