Drawing text string with higher font on image by using imagettftext() using PHP GD

<?Php
header ("Content-type: image/jpg");

$height=100; // Canvas Height
$width=300;   //  Canvas Width 
$text="plus2net";   // Text string to be written on Image. 
$x=10;
$y=70;
$font_size=60; // size of the font to be written 
$rotation=0; // angle of rotation of text 
$font_f = 'arial.ttf'; // font family , set the path to arial.ttf file
///// Create the image ////////
$im = @ImageCreate ($width,$height)
or die ("Cannot Initialize new GD image stream");

$background_color = ImageColorAllocate ($im, 204, 204, 204); 
$text_color = ImageColorAllocate ($im, 51, 51, 255); 
imagettftext($im, $font_size, $rotation, $x, $y, $text_color, $font_f, $text);
ImageJpeg ($im); // image displayed
imagedestroy($im); // Memory allocation for the image is removed. 
?>

We saved the above code in a PHP file as gd-imagettftext-demo.php and displayed it as Image by using HTML code.

Adding text to image by using PHP GD function imagettftext() with options to rotate & x y positions

Note:Prior to PHP 8.0.0, imagefttext() was an extended variant of imagettftext() which additionally supported the extrainfo. As of PHP 8.0.0, imagettftext() is an alias of imagefttext().

Syntax

imagettftext($source_image,$font_size,$rotation, $int_x,$int_y,
		$colour,$font_f,$text,$options)

$source_image : Image resource created before
$font_size: Size of font
$rotation : Angle of rotation in degree, default 0, positive value means counter-clockwise rotation.
$int_x: Position of font in Horizontal X axis, Leftmost point is 0
$int_y: Postion of the font in Vertical Y Axis, Topmost point is 0
$colour: Font colour
$font_f: Font family
$text: Text string to be written on the image
$options: Color created before using imagecolorallocate().

By using imagettftext() we can use font of any size ( more than 5 ),
whereas by using imagestring() maximum font size of 5 can be used.

Note : The font here arial.ttf file has to be placed and proper path is to be given.

Adding shadow to text

Dropping shadow from text written over Image with colour using imagettftext() PHP GD function

<?Php
header ("Content-type: image/jpg");

$height=100; // Canvas Height
$width=300;   //  Canvas Width 
$text="plus2net";   // Text string to be written on Image. 
$x=0;
$y=70;
$font_size=60; // size of the font to be written 
$rotation=0; // angle of rotation of text 
$font_f = 'font/arial.ttf'; // font family 
//$font = 'Times';  // font family 
///// Create the image ////////
$im = @ImageCreate ($width,$height)
or die ("Cannot Initialize new GD image stream");

$background_color = ImageColorAllocate ($im, 204, 204, 204); 
$text_color = ImageColorAllocate ($im, 51, 51, 255); 
$shadow_color= ImageColorAllocate ($im, 0, 0, 0); 
imagefttext($im, $font_size, $rotation, $x+2, $y+2, $shadow_color, $font, $text);
imagefttext($im, $font_size, $rotation, $x, $y, $text_color, $font_f, $text);
ImageJpeg ($im); // image displayed
imagedestroy($im); // Memory allocation for the image is removed. 
?>

Curved Text

Adding curved text written over Image with colour using imagettftext() PHP GD function

Change the total angle of rotation required.

$degDelta = 360 / ($length); // Change in angle for each char

<?php
header("Content-type: image/jpg");
$im = imagecreate(200,100); // width , height 
$background = imagecolorallocate($im, 204,204,204);
$blue = imagecolorallocate($im, 0,0,255);

$cx = 100;// center X position , from left 
$cy = 70;// center Y position , from top  
$cr = 40; // Radius 
$font_size=15;
$angle_degree=180; // total angle of rotation 
$text='plus2net.com'; // text to be used 
$text_length = strlen($text); // number of chars in string
$angle_Delta = $angle_degree / ($text_length); // Change in angle 
if ($text_length > 0) {
for ($d = 0; $d < $text_length; $d++) {
        // x and y coordinates for the char
        $deltaX = $cx - cos(deg2rad($angle_Delta * $d)) * $cr;
        $deltaY = $cy - sin(deg2rad($angle_Delta * $d)) * $cr;
imagefttext($im,$font_size,-($angle_Delta * $d + $angle_Delta / 2)+90,
    $deltaX, $deltaY, $blue, 'arial.ttf', $text[$d]);
}
}
//$path='D:\\php_files\\php_tutorial\\images\\gd-curved-text1.jpg';
//Imagejpeg ($im,$path); // save to path 
Imagejpeg($im); // display in browser
imagedestroy($im); //memory is removed. 
?>
