How to make Like This Image?
I just want to learn how do i get output like this using GD library,
Thanks for your help guys..
Here is your code, you could easily find it on google tho.
<?php
header ("Content-type: image/png");
$string = "your text"; // Change this text
$font = 4; // try changing this as well
$width = imagefontwidth($font) * strlen($string) ;
$height = imagefontheight($font) ;
$im = imagecreatefrompng("/path/to/yourimagefile");
$x = imagesx($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);
?>
Here's an example:
header('Content-Type: image/png'); // setting the content-type
$file = "yourimage.png";
$image = imagecreatefrompng($file); // creating the image
$font = "YourFont.ttf";
$size = 15; //pixels
$color = imagecolorallocate($image, 255, 255, 255); //white color
$text = "Your text here"
imagettftext($image, 15, 0, 20, 40, $color, $font, $code); // adding the text
imagepng($image); // outputting the image
For more see imagettftext().
EDIT: An example of using multiple imagettftext():
header('Content-Type: image/png'); // setting the content-type
$file = "yourimage.png";
$image = imagecreatefrompng($file); // creating the image
$font = "YourFont.ttf";
$size = 15; //pixels
$color = imagecolorallocate($image, 255, 255, 255); //white color
$text = "Your text here"
imagettftext($image, 15, 0, 20, 40, $color, $font, $code); // adding the text
$text = "Text 2";
imagettftext($image, 15, 0, 25, 45, $color, $font, $code); // adding the text
$text = "Text 3";
imagettftext($image, 15, 0, 30, 50, $color, $font, $code); // adding the text
imagepng($image); // outputting the image

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
i want to align the text generated on the image to the center of the image. for the moment, i dont know if it is possible to align it. below is the code.
$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";
$name = $uploads_dir.$fbid.".png"; //this saves the image inside uploaded_files folder
// 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);
imagedestroy($im);
thanks for the help guys.

// Using imagepng() results in clearer text compared with imagejpeg()
//imagepng($im);

imagedestroy($im);
You can use stil/gd-text class. Disclaimer: I am the author.
<?php
use GDText\Box;
use GDText\Color;
$im = #imagecreatefromjpeg('poloroid.jpg');
$textbox = new Box($im);
$textbox->setFontSize(20);
$textbox->setFontFace('verdana.ttf');
$textbox->setFontColor(new Color(0, 0, 0)); // black
$textbox->setTextShadow(
new Color(0, 0, 0, 80), // black color, but 60% transparent
0,
-1 // shadow shifted 1px to top
);
$textbox->setBox(
0, // distance from left edge
0, // distance from top edge
imagesx($im), // textbox width, equal to image width
imagesy($im) // textbox height, equal to image height
);
// now we have to align the text horizontally and vertically inside the textbox
// the texbox covers whole image, so text will be centered relatively to it
$textbox->setTextAlign('center', 'center');
// it accepts multiline text
$textbox->draw($text);
$uploads_dir = 'uploaded_files/';
//image file name
//$name ="$fbid.png";
$name = $uploads_dir.$fbid.".png"; //this saves the image inside uploaded_files folder
imagepng($im, $name, 9);
imagedestroy($im);
Demonstration:
I've updated your code a little:
function ImageTTFCenter($image, $text, $font, $size, $angle = 45)
{
$xi = imagesx($image);
$yi = imagesy($image);
$box = imagettfbbox($size, $angle, $font, $text);
$xr = abs(max($box[2], $box[4]));
$yr = abs(max($box[5], $box[7]));
$x = intval(($xi - $xr) / 2);
$y = intval(($yi + $yr) / 2);
return array($x, $y);
}
$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";
$name = $uploads_dir.$fbid.".png"; //this saves the image inside uploaded_files folder
list($x, $y) = ImageTTFCenter($im, $text, $font, 20)
// Add some shadow to the4 text
imagettftext($im, 20, 0, $x, $y+1, $grey, $font, $text);
// Add the text
imagettftext($im, 20, 0, $x, $y, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
//imagepng($im);
imagepng($im,$name,9);
imagedestroy($im);
The ImageTTFCenter function will find the center coordinates of you image which you will tell imagettftext
foreach ($user as $key=>$value){
$bb = imagettfbbox($value['font-size'],0,$fontname,$value['name']);
$WW = abs($bb[2]-$bb[0]);
$XX = ($value['XPos']+$WW);
$HH = abs($bb[5]-$bb[3]);
$HH +=1;
$HHH += $HH;
imagettftext($im, $value['font-size'], 0, $value['XPos'], $value['YPos'], $color[$value['color']], $fontname, $value['name']);
$HHH += 1;
$WIDE = abs($bb[2]-$bb[0]);
$endpoint=$value['XPos']+$WIDE;
$bb2 = imagettfbbox($value['font-size'],0,$fontname,$value['name']);
$WW2 = abs($bb2[2]-$bb2[0]);
$x2pos= $endpoint-$WW2;
imagettftext($im, $value['font-size'], 0, $x2pos, $value['YPos'], $color[$value['color']], $fontname, $value['name']);
}
I have this code
<?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... a very long text';
// 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);
?>
the problem here is, when I have a very long text, the other won't show.
I've searched that it can be done by
imagettfbbox()
but I don't know how to apply it here.
Any help?
try this code:
<?php
// Set the content-type
header('Content-type: image/png');
$img_width = 400;
$img_height = 30;
// Create the image
$im = imagecreatetruecolor($img_width, $img_height);
// 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, $img_width, $img_height, $white);
// The text to draw
$text = 'Testing... a very long text bla.. ';
// Replace path by your own font path
$font = 'arial.ttf';
$fontSize = $img_width / strlen($text) * 1.8;
// Add some shadow to the text
imagettftext($im, $fontSize, 0, 11, 21, $grey, $font, $text);
// Add the text
imagettftext($im, $fontSize, 0, 10, 20, $black, $font, $text);
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>
New update code :
<?php
// Set the content-type
header('Content-type: image/png');
$img_width = 400;
$img_height = 30;
$font = 'arial.ttf';
// Create the image
$text = 'Testing... a very long text.. Testing... a very long text.. Testing... a very long text.. Testing... a very long text..';
$curTextLen = strlen($text);
$limit = 35;
$totalLine = ceil($curTextLen / $limit);
$img_height = $img_height * $totalLine;
$im = imagecreatetruecolor($img_width, $img_height);
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, $img_width, $img_height, $white);
for($i = 1; $i <= $totalLine; $i++){
$y = $i * 27;
$textN = substr($text,($limit * ($i-1)),$limit);
imagettftext($im, 20, 0, 11, $y, $grey, $font, $textN);
// Add the text
imagettftext($im, 20, 0, 10, $y, $black, $font, $textN);
}
// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>
All the examples I've found on the web seem to create pngs with text from an existing png. Is it possible to create a transparent png from scratch and then add text?
The code ive got so far follows (but it doesnt work. just outputs a blank image source)
<?php
$width = 150;
$height = 30;
$text = "My Text";
$fontsize = 5;
$im = imagecreate($width, $height);
$transcolor = imagecolortransparent($im);
imagestring($im, $fontsize, 0, 0, $text, $transcolor);
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>
<?php
$font = 25;
$string = 'My Text';
$im = #imagecreatetruecolor(strlen($string) * $font / 1.5, $font);
imagesavealpha($im, true);
imagealphablending($im, false);
$white = imagecolorallocatealpha($im, 255, 255, 255, 127);
imagefill($im, 0, 0, $white);
$lime = imagecolorallocate($im, 204, 255, 51);
imagettftext($im, $font, 0, 0, $font - 3, $lime, "droid_mono.ttf", $string);
header("Content-type: image/png");
imagepng($im);
imagedestroy($im);
?>
Use imagestring instead of imagettftext if you don't want custom font.
Here's the solution based on your original code.
<?php
$width = 640;
$height = 480;
$text = "My Text";
$fontsize = 5;
$img = imagecreate($width, $height);
// Transparent background
$black = imagecolorallocate($img, 0, 0, 0);
imagecolortransparent($img, $black);
// Red text
$red = imagecolorallocate($img, 255, 0, 0);
imagestring($img, $fontsize, 0, 0, $text, $red);
header('Content-type: image/png');
imagepng($img);
imagedestroy($img);
?>
I Think GD is one of the most popular for generating images, with imagettftext.
<?php
$text = 'SOME TEXT';
$font="c:/windows/Fonts/Latinwd.ttf"; //Load font file for windows
$im = ImageCreate(700, 140);
$bla = imagecolorallocate($im, 0, 0, 0);
imagecolortransparent($im, $bla); //transparent background
$black = imagecolorallocate($im, 255,255,255);
ImageTTFText ($im, 38, 0, 10, 40, $black, $font, $text);
header('Content-Type: image/png');
ImagePNG($im, 'name.png');
imagedestroy($im);
?>
<?php
header ("Content-type: image/pjpeg");
$string = "manujagadeesh!!!";
$font =8;
$width = ImageFontWidth($font)* strlen($string) ;
$height = ImageFontHeight($font) ;
$im = ImageCreateFromjpeg("sachin.jpg");
$x=100;
$y=200;
$background_color = imagecolorallocate ($im, 255, 255, 255); //white background
$text_color = imagecolorallocate ($im, 0, 0,0);//black text
imagestring ($im, $font, $x, $y, $string, $text_color);
imagejpeg ($im);
?>
this is the add text to image in php
wen we inclue the my html page the text is not displaying
for eg
<?php
header ("Content-type: image/pjpeg");
$string = "manujagadeesh!!!";
$font =8;
$width = ImageFontWidth($font)* strlen($string) ;
$height = ImageFontHeight($font) ;
$im = ImageCreateFromjpeg("sachin.jpg");
$x=100;
$y=200;
$background_color = imagecolorallocate ($im, 255, 255, 255); //white background
$text_color = imagecolorallocate ($im, 0, 0,0);//black text
imagestring ($im, $font, $x, $y, $string, $text_color);
imagejpeg ($im);
?>
hi welcome
couldn't see the hi wlecome
You can't output both content of type image/jpeg and text/html from the same PHP script. Move your image generation code to another file eg stringImage.php and use the following code to include it:
<img src="stringImage.php" />
hi welcome
As long as stringImage.php only outputs the image data with the correct content type, and nothing else, you should get your expected result.
