PHP code:
<?php
ob_start();
session_start();
$_SESSION['secure'];
header('content-type:image/png');
$text="hello";
$font_size=25;
$width=200;
$height=200;
$image=imagecreate($width, $height);
imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image, 0, 0, 0);
for($x=1; $x <= 30; $x++) {
$x1 = rand(1, 100);
$y1 = rand(1, 100);
$x2 = rand(1, 100);
$y2 = rand(1, 100);
imageline($image, $x1, $y1, $x2, $y2, $black);
}
imagettftext($image, $font_size, 0, 15, 30, $black, 'consolas.ttf', $text);
$imgSrc="out.png";
imagejpeg($image, $imgSrc);
?>
When the image is generated, only lines are drawn but text("hello") is not drawn on it.
The font is also in the same directory, I have also kept it in another directory and added the complete path no luck.
I'm debugging this issue and found that font file is not accessible.
I have checked by turning on debugging as below:
error_reporting(E_ALL);
ini_set("display_errors", 1);
And commented lines below.
header('content-type:image/png');
imagepng($image);
Got error:
Warning: imagettftext(): Could not find/open font in
/var/www/html/index.php on line 24
Soultion:
Path to font file should be realpath on server. So the code should be:
imagettftext($image, $font_size, 0, 15, 30, $black, realpath('consolas.ttf'), $text);
Also change in render image without giving $imgSrc and changing it to
imagepng($image);
instead of
$imgSrc="out.png";
imagejpeg($image, $imgSrc);
Finally complete code will look like:
ob_start();
session_start();
$_SESSION['secure'];
header('content-type:image/png');
$text = "hello";
$font_size = 25;
$width = 200;
$height = 200;
$image = imagecreate($width, $height);
imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image, 0, 0, 0);
for ($x = 1; $x <= 30; $x++) {
$x1 = rand(1, 100);
$y1 = rand(1, 100);
$x2 = rand(1, 100);
$y2 = rand(1, 100);
imageline($image, $x1, $y1, $x2, $y2, $black);
}
imagettftext($image, $font_size, 0, 15, 30, $black, realpath('Consolas.ttf'), $text);
imagepng($image);
I have an image and I'm trying to watermark the image using text.
I have done with code part, but no image see been viewed with watermark text.
Here is the code below:
$imagetobewatermark="images/muggu.png";
list($width,$height)=getimagesize($imagetobewatermark);
$imagetobewatermark=imagecreatetruecolor($width,$height);
$mark=imagecreatefrompng($imagetobewatermark);
imagecopy($imagetobewatermark,$mark,0,0,0,0,$width,$height);
$wartermarktext="Muggu";
$font="../font/century gothic.ttf";
$fontsize="15";
$white = imagecolorallocate($imagetobewatermark, 255, 255, 255);
imagettftext($imagetobewatermark, $fontsize, 0, 20, 10, $white, $font, $watermarktext);
header("Content-type:image/png");
imagepng($imagetobewatermark);
imagedestroy($imagetobewatermark);
Tell me If I'm wrong.
Thank you.
One problem I can see straight away is that the $imagetobewatermark variable starts off as a string, then becomes a new blank image object (not an existing image), and when you subsequently create the mark image object, it's not going to work because $imagetobewatermark is no longer a string.
Try:
$imagetobewatermark=imagecreatefrompng("images/muggu.png");
$watermarktext="Muggu";
$font="../font/century gothic.ttf";
$fontsize="15";
$white = imagecolorallocate($imagetobewatermark, 255, 255, 255);
imagettftext($imagetobewatermark, $fontsize, 0, 20, 10, $white, $font, $watermarktext);
header("Content-type:image/png");
imagepng($imagetobewatermark);
imagedestroy($imagetobewatermark);
EDIT:
I failed to notice a typo in your text variable $wartermarktext, which should be $watermarktext.
Correct this and it should work.
You had some spellings wrong and did not use the ressource. Here corrected:
$imagetobewatermark = "muggu.png";
list ($width, $height) = getimagesize($imagetobewatermark);
$res = imagecreatetruecolor($width, $height);
$mark = imagecreatefrompng($imagetobewatermark);
//make sure here to use the ressource, not the filepath
imagecopy($res, $mark, 0, 0, 0, 0, $width, $height);
$watermarktext = "Muggu";
//$font = "../font/century gothic.ttf";
//I copied it to my local test folder
$font = "GOTHIC.TTF";
$fontsize = "15";
//make sure here to use the ressource, not the filepath
$white = imagecolorallocate($res, 255, 255, 255);
//make sure here to use the ressource, not the filepath
imagettftext($res, $fontsize, 0, 20, 10, $white, $font, $watermarktext);
header("Content-type:image/png");
//make sure here to use the ressource, not the filepath
imagepng($res);
//make sure here to use the ressource, not the filepath
imagedestroy($res);
you have to give Public/Absolute Path for Font arial.ttf.
Solution is tested in Laravel 5.8.
you can use this solution. here [ $SourceFile , $DestinationFile ] are Absolute Path of local directory. $imgUrl is HTTP based URL. Watermark will be placed at the top of the image.
function watermarkImage ($SourceFile, $WaterMarkText, $DestinationFile,$imgUrl) {
list($width, $height) = getimagesize($SourceFile);
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($SourceFile);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width, $height);
$black = imagecolorallocate($image_p, 255, 255, 255);
$font = public_path('fonts/arial.ttf');
$font_size = 8;
imagettftext($image_p, $font_size, 0, 10, 20, $black,$font , $WaterMarkText);
if ($DestinationFile <> '') {
imagejpeg ($image_p, $DestinationFile, 100);
} else {
header('Content-Type: image/jpeg');
imagejpeg($image_p, null, 100);
};
imagedestroy($image);
imagedestroy($image_p);
return $imgUrl;
}
Try this.
$imagetobewatermark = "images/muggu.png";
$watermarktext = "Muggu";
list($width, $height) = getimagesize($imagetobewatermark);
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefrompng($imagetobewatermark);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width, $height);
$font = "../font/century gothic.ttf";
$font_size = 15;
$white = imagecolorallocate($image_p, 255, 255, 255);
imagettftext($image_p, $font_size, 0, 20, 20, $white, $font, $watermarktext);
header("Content-Type: image/png");
imagepng($image_p, null, 0);
imagedestroy($image);
imagedestroy($image_p);
Try this code, It helps you to provide the watermark for the images.
<?php
header('Content-type: image/jpeg'); //SET THE FORMATE OF THE IMAGE
$jpg_image = imagecreatefromjpeg('images.jpg'); //GIVE LINK FOR SPECIFIED IMAGE
$color = imagecolorallocate($jpg_image, 500, 500, 500); //GIVE COLOR TO WATERMARK TEXT
$font_location = 'BROADW.TTF'; //WATERMARK FONT
$text = "http://www.sanwebtutorials.blogspot.in/"; //WATERMARK TEXT
$x=200; //X CO-ORDINATE
$y=800; //Y CO-ORDINATE
$size=21; //SIZE OF TEXT
imagettftext($jpg_image,$size, 0, $x, $y, $color, $font_location, $text); //PRINT TEXT ON IMAGE
imagejpeg($jpg_image); //SEND IMAGE TO BROWSER
imagedestroy($jpg_image); //DESTROY THE MEMORY
?>

Ok, here is the problem. This code works on localhost, but not on a live site
<?php
session_start();
header('Content-type: image/jpeg');
$text = $_SESSION['secure'];
$font_size = 30;
$image_width = 120;
$image_height = 40;
$image = imagecreate($image_width, $image_height);
imagecolorallocate($image, 255, 255, 255);
$text_color = imagecolorallocate($image, 0, 0, 0);
$line_color = imagecolorallocate($image, 0, 0, 0);
for($x=1; $x<=30; $x++){
$x1 = rand(1, 100);
$y1 = rand(1, 100);
$x2 = rand(1, 100);
$y2 = rand(1, 100);
imageline($image, $x1, $y1, $x2, $y2, $line_color);
}
imagettftext($image, $font_size, 0, 15, 30, $text_color, 'font2.ttf', $text);
imagejpeg($image);
?>
The localhost and the webhosting are both running the same php version
Take a look at this picture before you post anything, please!:

try to look at error.log (APACHE), it could also be
possible that there is a session problem, you could
try to hide all errors by using "error_reporting(0);
try this:
<?php
#session_start();
error_reporting(0);
#header('Content-type: image/jpeg');
$text = $_SESSION['secure'];
$font_size = 30;
$image_width = 120;
$image_height = 40;
$image = imagecreate($image_width, $image_height);
imagecolorallocate($image, 255, 255, 255);
$text_color = imagecolorallocate($image, 0, 0, 0);
$line_color = imagecolorallocate($image, 0, 0, 0);
for ($x=1; $x<=30; $x++) {
$x1 = rand(1, 100);
$y1 = rand(1, 100);
$x2 = rand(1, 100);
$y2 = rand(1, 100);
imageline($image, $x1, $y1, $x2, $y2, $line_color);
}
imagettftext($image, $font_size, 0, 15, 30, $text_color, 'font2.ttf', $text);
imagejpeg($image);
?>
but the best, would be to fix the error, so look # the error.log
http://php.net/manual/en/function.error-reporting.php
if you got any error message, you could tell us - so we will try to help you :)
there are some error at your code, but it's not the PHPGD lib error, please notice code below:
<?php
//session_start();
header('Content-Type: image/jpeg');
//$_SESSION['secure']; disabled, this will lead to notice: undefined index
$text = "he123";
$font_size = 30;
$image_width = 120;
$image_height = 40;
$image = imagecreate($image_width, $image_height) or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($image, 255, 255, 255); //add background color
$text_color = imagecolorallocate($image, 255, 0, 0); //red for the text
$line_color = imagecolorallocate($image, 0,255,0); // green for the line
for($x=1; $x<=30; $x++) {
$x1 = rand(1, 100);
$y1 = rand(1, 100);
$x2 = rand(1, 100);
$y2 = rand(1, 100);
imageline($image, $x1, $y1, $x2, $y2, $line_color);
}
// add ./ to the font name
imagettftext($image, $font_size, 0, 15, 30, $text_color, "./font2.ttf", $text);
imagejpeg($image);
imagedestroy($image); // remember to clear the chace :p
?>
here's the output
I used the following code to create Captcha to my form. Captcha creating well. Now I want to change font-size, and Font character spaces. I don't know how to change in the following code.
<?php
session_start();
$code= substr(str_shuffle("abcdefghijklmnopqrstuvwxyz"), 0, 6);
$_SESSION["code"]=$code;
$im = imagecreatetruecolor(150, 35);
$bg = imagecolorallocate($im, 255, 255, 255);
$fg = imagecolorallocate($im, 0, 0, 0);
imagefill($im, 5, 5, $bg);
imagestring($im, 5, 8, 8, $code, $fg);
header("Cache-Control: no-cache, must-revalidate");
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>
You can use the code below to implement a simple captcha using gd library of PHP. As you are beginner, here is a sample code for quick testing, it covers font-sizing also:
<?php
session_start();
header('Content-type: image/jpeg');
$text = rand(1000, 9999);
$font_size = 30;
$image_width = 200;
$image_height = 40;
$image = imagecreate($image_width, $image_height);
imagecolorallocate($image, 255, 255, 255);
$text_color = imagecolorallocate($image, 0, 0, 0);
for ($x=1; $x<=40; $x++) {
$x1 = rand(1, 100);
$y1 = rand(1, 100);
$x2 = rand(1, 100);
$y2 = rand(1, 100);
imageline($image, $x1, $y1, $x2, $y2, $text_color);
}
imagettftext($image, $font_size, 0, 15, 30, $text_color, 'FREESCPT.ttf', $text);
imagejpeg($image);
?>
In imagettftext function:
imagettftext($image, $font_size, $angle, $x, $y, $text_color, '$font-family', $text);
$image is the $imagecreate function
$font_size is the size of font you want.
$angle is the angle of the fonts tilted
$x and $y are coordinates.
$text_color is the imagecolorallocate function
$font-family is the family of font you want to use
$text is the text or random text to be displayed
Here is the good tutorial on how to build captcha in php -> link
you can change font using imagestring function
Here is an example what I would like to do:
Here is the result:
function red_rectangle($img_src,$x1,$y1,$x2,$y2,$tr = 50)
{
// Load image
$img = imagecreatefromjpeg($img_src);
// Transparent red
$red = imagecolorallocatealpha($img, 255, 0, 0, $tr);
// Draw a white rectangle
imagefilledrectangle($img, $x1, $y1, $x2, $y2, $red);
// Save the image (overwrite)
imagejpeg($img, $img_src);
imagedestroy($img);
}
You need to use http://php.net/manual/en/function.imagefilledrectangle.php, passing a color created with http://www.php.net/manual/en/function.imagecolorallocatealpha.php.
As you can see, the example for http://php.net/manual/en/function.imagefilledrectangle.php is pratically what to you want to do.
function red_rectangle($img_src,$x1,$y1,$x2,$y2,$tr = 100)
{
// Load image
$img = imagecreatefromjpeg($img_src);
// Transparent red
$red = imagecolorallocatealpha($img, 255, 0, 0, $tr);
// Draw a white rectangle
imagefilledrectangle($img, $x1, $y1, $x2, $y2, $red);
// Don't forget to output a correct header
header('Content-Type: image/jpg');
// Save the image (overwrite)
imagejpeg($img);
imagedestroy($img);
}
$img_src = 'test.jpg';
$x1= 500;
$y1= 450;
$x2 = 370;
$y2=180;
red_rectangle($img_src,$x1,$y1,$x2,$y2);
