php - 如何在php中编辑后保存图像

Question

我有一个图像，我使用 php“imagettftext”函数在该图像上写了一些文本。现在我不知道它如何自动保存。

header('Content-Type: image/png');
// Create the image
$im = imagecreatefromjpeg('image-1.jpg');

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
//imagefilledrectangle($im, 0, 0, 399, 29, $white);

// The text to draw
$text = 'www.blockprintsonline.com';

// Replace path by your own font path
$font = 'arial.ttf';

list($width, $height, $type, $attr) = getimagesize($get_image);
$width1=$width*20/100;
$height1=$height*50/100;
$font_size=$width*4/100;

// Add some shadow to the text
//imagettftext($im, 30, 0, 11, 21, $grey, $font, $text);

// Add the text
imagettftext($im, $font_size, 0, $width1, $height1, $black, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);

如果要将图像保存到文件中，请查看 imagepng() 函数的文档 here .

通过传递文件名作为第二个参数，它将图像保存到文件中，例如:

imagepng($im, "path/to/save/image/in.png");
