I have code to generate an image:
<?php
ini_set('display_errors', 1);
$members = json_decode(file_get_contents('https://discord.com/api/guilds/828207694284193802/widget.json'), true)['members'];
$membersCount = 0;
foreach ($members as $member) {
if ($member['status'] == 'online') {
$membersCount++;
}
}
$img = imagecreatetruecolor(380, 80);
$white = imagecolorallocate($img, 255,255,255);
putenv('GDFONTPATH=' . realpath('.'));
$font = "arial.ttf";
$txt = "ONLINE: " . $membersCount;
$image_width = imagesx($img);
$image_height = imagesy($img);
$text_box = imagettfbbox(30,0, $font,$txt);
$text_width = $text_box[2]-$text_box[0];
$text_height = $text_box[7]-$text_box[1];
$x = ($image_width/2) - ($text_width/2);
$y = ($image_height/2) - ($text_height/2);
imagettftext($img, 30, 0, $x, $y, $white, $font, $txt);
header('Content-Type: image/png');
imagepng($img);
imagedestroy($img);
?>
And I want to display a result on my forum:
<img src="http://s52518.web101.svpj.pl/banners/counter_dc.php" alt="" />
But the result is:
Or an empty box:
My PHP code is working well:
I want add the image in HTML to my sidebar/box (I don't know how it's named). It's a Discord online users counter.

I want to add a text to a image. The text should be displayed in multiple areas of the image (not just one).
For example I want to watermark with a text stack. Stack should be displayed in the image at least 8 times in different areas in the image.
I just learned about imagestring() and imagettftext(), but these two only displays my text on a single spot.
Image is not fixed size, so i cannot specify exact and multiple location in advance. It should work on all sizes of images
<?php
/*
image.php
*/
header("Content-type: image/jpeg");
$imgPath = 'olximage.jpg';
$image = imagecreatefromjpeg($imgPath);
$color = imagecolorallocate($image, 255, 255, 255);
$string = "stack overflow";
$fontSize = 3;
$x = 15;
$y = 185;
imagestring($image, $fontSize, $x, $y, $string, $color);
$x = 15;
$y = 175;
imagestring($image, $fontSize, $x, $y, $string, $color);
imagejpeg($image);
?>
Thanks in advance
For example:
<?php
/*
image.php
*/
header("Content-type: image/jpeg");
$imgPath = 'olximage.jpg';
$image = imagecreatefromjpeg($imgPath);
$color = imagecolorallocate($image, 255, 255, 255);
$string = "stack overflow";
$fontSize = 3;
$imageHeight = imagesy($image);
$distanceY = 10;
$maxImageStrings = max(8, $imageHeight / $distanceY);
$x = 15;
for ($i = 0; $i < $maxImageStrings; $i++) {
$y = $i * $distanceY;
imagestring($image, $fontSize, $x, $y, $string, $color);
}
imagejpeg($image);
You can finetune calculations for your needs.
I'm using Imagick extension for same. If you want to go with this then follow detail:
PHP:
// Create objects
$image = new Imagick('image.png');
$watermark = new Imagick();
// Watermark text
$text = 'Copyright';
// Create a new drawing palette
$draw = new ImagickDraw();
$watermark->newImage(140, 80, new ImagickPixel('none'));
// Set font properties
$draw->setFont('Arial');
$draw->setFillColor('grey');
$draw->setFillOpacity(.5);
// Position text at the top left of the watermark
$draw->setGravity(Imagick::GRAVITY_NORTHWEST);
// Draw text on the watermark
$watermark->annotateImage($draw, 10, 10, 0, $text);
// Position text at the bottom right of the watermark
$draw->setGravity(Imagick::GRAVITY_SOUTHEAST);
// Draw text on the watermark
$watermark->annotateImage($draw, 5, 15, 0, $text);
// Repeatedly overlay watermark on image
for ($w = 0; $w < $image->getImageWidth(); $w += 140) {
for ($h = 0; $h < $image->getImageHeight(); $h += 80) {
$image->compositeImage($watermark, Imagick::COMPOSITE_OVER, $w, $h);
}
}
// Set output image format
$image->setImageFormat('png');
// Output the new image
header('Content-type: image/png');
echo $image;
although there are plenty of command-line examples to be found on the ImageMagick website, so that is where we shall begin.
everybody.
my code is
<?php
header("Content-type: image/jpeg");
$imgPath = 'logo.jpg';
$image = imagecreatefromjpeg($imgPath);
$color = imagecolorallocate($image, 000, 000, 255);
$string = "A&B UK LIMITED";
$fontSize = 5;
$x = 19;
$y = 197;
imagestring($image, $fontSize, $x, $y, $string, $color);
imagejpeg($image,"test.jpg", 85);
?>
in code $string variable has a special character and that why my code doesn't work
is there any body know how to fix this problem,
but If i cahange the value of $string variable it does work. Example $string="test Company";
Do it like below
header("Content-type: image/jpeg");
$imgPath = 'http://upload.wikimedia.org/wikipedia/en/3/37/VII-200-bakside.jpg';
$image = imagecreatefromjpeg($imgPath);
$color = imagecolorallocate($image, 0,0, 250);
$string = "A&B UK LIMITED";
$fontSize = 5;
$x = 50;
$y = 50;
imagestring($image, $fontSize, $x, $y, $string, $color);
imagejpeg($image,'test.jpeg',75);
imagejpeg($image);
output:
I'm trying to create a dynamic image in php with some text in it but it says the image cannot be displayed because it contains errors. Here's my code

<?php

$font_size = 20;
$angle = 45;
$text_box = imagettfbbox($font_size,$angle,$font,$text);
$text_width = $text_box[2]-$text_box[0];
$text_height = $text_box[3]-$text_box[1];
//coord text
$x = ($image_width/2) - ($text_width/2);
$y = ($image_height/2) - ($text_height/2);
$textcolor = imagecolorallocate($img,255,255,255);
imagettftext($img, $font_size, 0, $x, $y, $textcolor, $font, $text);

I have the font file (verdana.ttf) in the same folder as my php file. I tried $font = 'verdana.ttf'; and got the same error.
You need to have the font in your web server and call it.
$font = 'path/verdana.ttf';
i tested your code, and work fine in my server.
why this show only the background image, and not the text?
Without backgroundimage it's work...
$code = rand(1000, 99999);
$_SESSION["code"] = $code;
$font = '../fonts/captcha.ttf';
$y = 30;
$x = 10;
$width = 100; //Image width in pixels
$height = 40; //Calculating image height
$image = ImageCreate($width, $height);
$img = imagecreatefromgif('img/captcha.gif');
$bgtext = imagecolorallocate($img, 145,145,145);
ImageTTFText($image, 16, 0, $y, $y, $bgtext, $font, $code);
header('Content-type: image/png');
imagegif($img);
imagedestroy($img);
I'm trying to use the following PHP in order to apply randomly generated text files to an image. (I'm just using a random image right now.)
<?php
header ("Content-type: image/png");
$textfile = "quote.txt";
$quotes = array();
if(file_exists($textfile)){
$quotes = file($textfile);
srand ((float) microtime() * 10000000);
$string = $quotes[array_rand($quotes)];
$string = substr($string,0,strlen($string)-1);
}
else{
$string = "No 'Quote' available at this time.";
}
//$string = "your text";
// try changing this as well
$font = 4;
$width = imagefontwidth($font) * strlen($string) ;
$height = imagefontheight($font) ;
$im = imagecreatefrompng("test.png");
$x = imagesx($im) - $width ;
$y = imagesy($im) - $height;
$backgroundColor = imagecolorallocate ($im, 255, 255, 255);
$textColor = imagecolorallocate ($im, 0, 0,0);
imagestring ($im, $font, $x, $y, $string, $textColor);
imagepng($im);
ImageDestroy($im);
?>
However, when I run that code the imported image just becomes very blockish.
Here is the image I am testing with:
http://i.stack.imgur.com/LhNkv.png
And here is how it actually appears:
http://i.stack.imgur.com/AAcHZ.png
My research shows that "imagecreate" generates a "palette" image - and I thought that might have something to do with my error, but I have seen plenty of examples where the base image is by no means distorted.
Thanks in advance for your insights.
(Ugh. It wouldn't let me post images but let me upload them just fine?)
Update
Changing the code to:
<?php
header ("Content-type: image/png");
$textfile = "quote.txt";
$quotes = array();
if(file_exists($textfile)){
$quotes = file($textfile);
srand ((float) microtime() * 10000000);
$string = $quotes[array_rand($quotes)];
$string = substr($string,0,strlen($string)-1);
}
else{
$string = "No 'Quote' available at this time.";
}
//$string = "your text";
// try changing this as well
$font = 4;
$width = imagefontwidth($font) * strlen($string) ;
$height = imagefontheight($font) ;
$im = imagecreatefrompng("test.png");
//$x = imagesx($im) - $width ;
//$y = imagesy($im) - $height;
//$backgroundColor = imagecolorallocate ($im, 255, 255, 255);
//$textColor = imagecolorallocate ($im, 0, 0,0);
//imagestring ($im, $font, $x, $y, $string, $textColor);
imagepng($im);
ImageDestroy($im);
?>
Produces the same block-like effects as above, except now no text is being written to the image, either (obviously?).
Could be an alpha blending problem. Try adding these before saving the image:
imagealphablending($im, true);
imagesavealpha($im, true);
