Question

我正在使用Imagine和Zend Framework 2。

我正在寻找一种在保存之前在图像中添加文字的方法。

我试过这个：

我希望你们中的一个人可以帮忙解决问题。

我修正了，我使用了php函数：

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);
    }

Zend框架＆amp;想象一下：在图像中添加文字
