I have this script which generates an image:
$im = imagecreatetruecolor(110, 34);
$red = imagecolorallocate($im, 245, 245, 245);
imagefill($im, 0, 0, $red);
$text_color = imagecolorallocate($im, 80, 80, 80);
imagestring($im, 8, 15, 9, image, $text_color);
header('Content-Type: image/jpeg');
imagejpeg($im);
Now I want to save that image. How can I do that? Here is what I have tried so far:
file_put_contents("../img/name.jpg", file_get_contents($im));
What's wrong?

I'm making my own 'captcha' form and I now have a page that generates the image:
<?php
header('Content-Type: image/png');
$im = imagecreatetruecolor(200, 50);
$white = imagecolorallocate($im, 255, 255, 255);
$gray = imagecolorallocate($im, 160, 160, 160);
imagefilledrectangle($im, 0, 0, 200, 50, $white);
$captcha = "SOMErandomTEXT";
$font = 'Chewy.ttf';
imagettftext($im, 20, 0, 0, 20, $gray, $font, $captcha);
imagepng($im);
imagedestroy($im);
?>
Now I also have another page that shows this image, inside the form. Now I want to get the value $captcha from the page shown above on the other page. How can I do it?
Using sessions did the job for me.

I am trying to make a gamecard for a RSPS. This is my first time using PHP to generate text on images and when trying to apply this weird glitch happens:
But, when the original photo looks like this:
As you can see the corners are not curved like they should be. But, in the original it comes out fine. I am not talking about the location of the numbers.
Here is the code I am using:
<?php
header('Content-Type: image/png');
// Image Creation
$image_file = "SoulSplitCard.png";
$im = imagecreatefrompng($image_file);
//Colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
$rscol = imagecolorallocate($im, 23, 113, 183);
// Levels (for now)
$text = '99';
$text2 = '87';
// Font
$font = 'arial.ttf';
//Text Applications
imagettftext($im, 15, 0, 150, 35, $rscol, $font, $text);
imagettftext($im, 15, 0, 150, 81, $rscol, $font, $text2);
// Using imagepng() instead of imagejpeg()
imagepng($im);
imagedestroy($im);
?>
What is causing this to happen?
I have this PHP code:
<?php
//Other part of code
Header("Content-type: image/png");
$im = imagecreatefromPng("./images/signatures/background.png");
$red = ImageColorAllocate($im, 255, 0, 0);
$black = ImageColorAllocate($im, 0, 0, 0);
ImageString($im, 5, 15, 5, "$callsign", $black);
ImageString($im, 5, 15, 20, "$name $surname", $black);
ImageString($im, 5, 15, 35, "Location: $location", $black);
ImageString($im, 5, 15, 50, "HUB: $hub", $black);
ImageString($im, 5, 15, 65, "Hours: $hours", $black);
$font_width = ImageFontWidth(5);
ImagePng($im);
?>
I want to change the font that PHP uses to write in the image. How can i do that?? I try but I can´t.
Assuming that you mean font:
http://www.php.net/manual/en/function.imageloadfont.php
http://php.net/manual/en/function.imagettftext.php this may help if your using ttf fonts
You can use imageloadfont ();
syntax:
int imageloadfont ( string $file )
Example:
// Create a new image instance
$im = imagecreatetruecolor(50, 20);
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
// Make the background white
imagefilledrectangle($im, 0, 0, 49, 19, $white);
// Load the gd font and write 'Hello'
$font = imageloadfont('./04b.gdf');
imagestring($im, $font, 0, 0, 'Hello', $black);
// Output to browser
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
so change your code to:
//Other part of code
Header("Content-type: image/png");
$im = imagecreatefromPng("./images/signatures/background.png");
$font = imageloadfont('./fonts/arial.gdf');//change the parameter based on your font file name
$red = ImageColorAllocate($im, 255, 0, 0);
$black = ImageColorAllocate($im, 0, 0, 0);
ImageString($im, $font, 15, 5, "$callsign", $black);
ImageString($im, $font, 15, 20, "$name $surname", $black);
ImageString($im, $font, 15, 35, "Location: $location", $black);
ImageString($im, $font, 15, 50, "HUB: $hub", $black);
ImageString($im, $font, 15, 65, "Hours: $hours", $black);
$font_width = ImageFontWidth(5);
ImagePng($im);
I have an image which can show polylines. I can show the image perfectly but when i apply into website which not using header("Content-type: image/png"); i got problem.
Can i show the image that has been edited with PHP in website not just image.
here's my code
<?php
$img = imagecreatefromjpeg('1967_NL_MAJENEresize.jpg'); //you can change image name
$white = imagecolorallocate($img, 255, 255, 255);
$red = imagecolorallocate($img, 255, 0, 0);
imagesetthickness($img, 4);
imagefill($img, 0, 0, $white);
imageline($img, 100, 80, 210, 380, $white); //x1, y1, x2, y2
imageline($img, 200, 80, 210, 380, $white);
imageline($img, 200, 80, 310, 580, $white);
imagefilledrectangle ($img, (100-5), (80-5), 100+10, 80+10, $red);
imagefilledrectangle ($img, (210-5), (380-5), 210+10, 380+10, $red);
imagefilledrectangle ($img, (200-5), (80-5), 200+10, 80+10, $red);
imagefilledrectangle ($img, (310-5), (580-5), 310+10, 580+10, $red);
header("Content-type: image/png");
imagepng($img);
imagedestroy($img);
?>
You shouldn't include the image generating code in existing content, instead have a dedicated script to create the image using the correct header.
Link to the image from your content by using <img> tag
generate-image.php:
<?php
$imagefile = preg_replace('/[^A-Za-z0-9_\-]/', '_', $_GET['filename']);
$img = imagecreatefromjpeg($imgfile); //you can change image name
$white = imagecolorallocate($img, 255, 255, 255);
$red = imagecolorallocate($img, 255, 0, 0);
imagesetthickness($img, 4);
imagefill($img, 0, 0, $white);
imageline($img, 100, 80, 210, 380, $white); //x1, y1, x2, y2
imageline($img, 200, 80, 210, 380, $white);
imageline($img, 200, 80, 310, 580, $white);
imagefilledrectangle ($img, (100-5), (80-5), 100+10, 80+10, $red);
imagefilledrectangle ($img, (210-5), (380-5), 210+10, 380+10, $red);
imagefilledrectangle ($img, (200-5), (80-5), 200+10, 80+10, $red);
imagefilledrectangle ($img, (310-5), (580-5), 310+10, 580+10, $red);
header("Content-type: image/png");
imagepng($img);
imagedestroy($img);
?>
index.php:
Blah Blah
<img src='generate-image.php?filename=<?= $db->row['thumbnail']; ?>'>;
blah blah
I'm trying to use the GD graphics library to make this captcha image, and the box shows up how Id like it to, but the text isn't being displayed over the image at all. I can't figure out why it's not showing up.
<?php
session_start();
putenv('GDFONTPATH=' . realpath('.') );
$font = 'Molle';
header('Content-Type: image/png');
$im = imagecreatetruecolor(260, 40);
$white = imagecolorallocate($im, 255, 255,255);
$grey = imagecolorallocate($im, 215, 215, 215);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 3, 3, 255, 34, $grey);
$text = 'Testing';
$_SESSION["captcha"] = $text;
imagettftext( $im, 20, 0, 16, 26, $white, $font, $text );
imagettftext( $im, 20, 0, 15, 25, $black, $font, $text );
imagepng($im);
imagedestroy($im);
?>
