I try this code with imagettftext():
// Set the content-type
header('Content-Type: image/png');
// Create the image
$im = imagecreatetruecolor(400, 30);
// 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 = 'Testing...';
// Replace path by your own font path
$font = 'arial.ttf';
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
But it does not work as it should, I have GD and FreeType installed, as you can see:
Anyone can point me in right direction?
Assign variable $font to the absolute path of the font file.
// Replace path by your own font path
$font = 'arial.ttf';
Your code is looking for "arial.ttf" that does not exist. Please copy the font file (arial.ttf) into the same directory of your code.
Try to replace your path to font
$font = 'arial.ttf';
on
$font = __DIR__ .'\Arial.ttf';
or use absolute path (it's not correct but working), if you using windows system
$font = 'c:\WINDOWS\Fonts\Arial.ttf';

For example like this image:
[![x][1]][1]
The details of the image is get from this url: [Pine][2].
That's the full code:
It's show an image with updated data based on that link.
Can someone show me what I have to find in google for the details like this? what type is this code?
You should use GD library or Imagick(ImageMagick)

I'm trying to use the imagettftext() to add text to an image via PHP. So far I've gone through about 6 different tutorials, trying to get it to work, and I have had no success. I'm currently trying this code from the php documentation page.
<?php
// Set the content-type
header('Content-Type: image/png');
// Create the image
$im = imagecreatetruecolor(400, 30);
// 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 = 'Testing...';
// Replace path by your own font path
$font = 'arial.ttf';
// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>
However, nothing shows up. I have the GD library installed, as well as freetype enabled. I have arial.ttf in the same directory as the php file, and I cannot figure out why it wont work. All I get is a blank image.
EDIT: This is the error message "[19-Jan-2014 16:31:07] PHP Warning: imagettftext(): Could not find/open font in /var/www/php/bb/test.php on line 21"
I was about about to tell you to type the real path of the ttf instead of the relative path.
putenv('GDFONTPATH=' . realpath('.'));
or
$font = '/home/user/arial.ttf';
i have a image and i wrote some text on this image by using php "imagettftext" function. now i don't know that how it will save automatic.
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($im);
If you want to save the image to a file, check out the docs for the imagepng() function here.
By passing a filename as the second argument it will save the image to a file, e.g:
imagepng($im, "path/to/save/image/in.png");
<?php
// Save the image as 'simpletext.png'
imagepng($im, 'simpletext.png');
// Free up memory
imagedestroy($im);
?>
this is an example on how to save an image.
If you check the documentation for imagepng you would see that you can provide a filename. That would save the image to disk
I want to move a file that has been created using imagettftext and saved as a png. as you can see, in the code below, i used the move_uploaded_file but to no avail. please help.

// Set the content-type
header('Content-Type: image/png');
// Create the image from created image
//$im = imagecreatetruecolor(180, 180);
$im = #imagecreatefromjpeg('poloroid.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 = 'John...';
$fbid = $_POST["id"];
$text = $_POST["want"];
$fb_email =$_POST["email"];
$fb_name=$_POST["name"];
$uploads_dir = '/uploaded_files';
// Replace path by your own font path
$font = 'verdana.ttf';
//image file name
$name ="$fbid.png";
// Add some shadow to the text
imagettftext($im, 20, 0, 25, 126, $grey, $font, $text);
// Add the text
imagettftext($im, 20, 0, 25, 125, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
//imagepng($im);
imagepng($im,$name,9);
move_uploaded_file($name,"$uploads_dir/$name");
imagedestroy($im);
You are not uploading a file, you are generating one!
imagepng has filename parameter so you can save it to your drive:
$uploads_dir = '/uploaded_files/';
$name = $uploads_dir.$fbid.'.png';
imagepng($im,$name,9);
imagedestroy($im);
try to use rename instead of move_uploaded_file
What is the best way to display underlined text and output the result as image with GD or any other library?
You can try using the Unicode underline combining character U+0332.
<?php
// Set the content-type
header('Content-type: image/png');
// Create the image
$im = imagecreatetruecolor(400, 30);
// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);
// The text to draw
$text = "̲U̲d̲e̲r̲l̲i̲n̲e";
// Replace path by your own font path
$font = 'arial.ttf';
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

I am using this...
$font = imageloadfont($font_file);
$font_width = ImageFontWidth($font);
$font_height = ImageFontHeight($font);
$str_width = strlen($text)*$font_width;
ImageLine($image, $left, $top+$font_height, $left+$str_width, $top+$font_height, $color);
