Use PHP to create thumbnails. (Cropped to square)

Question

I have a php script im currently using that creates thumbnails based on a max width and height. However, I\'d like it to always create square images and crop the images whe

Answer 1

This modified function worked great for me

public function igImagePrepare($img,$name){
    $dir = 'my-images/';
    $img_name = $name.'-'.uniqid().'.jpg';

    //Your Image
    $imgSrc = $img;

    //getting the image dimensions
    list($width, $height) = getimagesize($imgSrc);

    //saving the image into memory (for manipulation with GD Library)
    $myImage = imagecreatefromjpeg($imgSrc);

    $square_size = 400;

    $width = imagesx( $myImage );
    $height = imagesy( $myImage );


                //set dimensions
                if($width> $height) {
                        $width_t=$square_size;
                        //respect the ratio
                        $height_t=round($height/$width*$square_size);
                        //set the offset
                        $off_y=ceil(($width_t-$height_t)/2);
                        $off_x=0;
                } elseif($height> $width) {
                        $height_t=$square_size;
                        $width_t=round($width/$height*$square_size);
                        $off_x=ceil(($height_t-$width_t)/2);
                        $off_y=0;
                }
                else {
                        $width_t=$height_t=$square_size;
                        $off_x=$off_y=0;
                }


   /* Create the New Image */
    $new = imagecreatetruecolor( $square_size , $square_size );
   /* Transcribe the Source Image into the New (Square) Image */
    $bg = imagecolorallocate ( $new, 255, 255, 255 );
    imagefill ( $new, 0, 0, $bg );
    imagecopyresampled( $new , $myImage , $off_x, $off_y, 0, 0, $width_t, $height_t, $width, $height );

    //final output
    imagejpeg($new, $dir.$img_name);

    return $dir.$img_name;
  }
