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

You should use GD library or Imagick(ImageMagick)

I'm trying to output a text to image using a font that has 7 stylistic sets. I'm using the code below but can't find how I can use a style in the output. Any advice would be greatly appreciated.
<?php
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 = 'This is a test!';
// Replace path by your own font path
$font = 'joined.otf';
// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>
I want to move a file that has been created using imagettftext and saved as a png. as you can see, in the code below, i used the move_uploaded_file but to no avail. please help.
tq
// Set the content-type
header('Content-Type: image/png');
// Create the image from created image
//$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
I want to create images for my dynamic text.
My problem is that I am reading folder name from some specific directory.
So folder name will be what ever but client wants that folder name should come as the images only.
So I thought that I will place one image with the same name as folder on any unique name.
But client don't want to create new images if they create a new folder.
So how can I do this with PHP?
I need to use some specific background color for image and also want to use some specific font for the text in image.
See imagefttext() in the examples section
From php.net:
http://pl2.php.net/manual/en/function.imagettftext.php
<?php
// Set the content-type
header('Content-type: image/png');
// Create the image
$im = imagecreatetruecolor(400, 30);

$grey = imagecolorallocate($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);

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);
?>
There are lots of FREE PHP CAPTCHA out there that come with a lot of customization, download one and see what exactly happens behind the scene. Also have a look at this link

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);
