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

Parameter-Liste

image

Ein GdImage-Objekt, das von einer der Funktionen zur Bilderzeugung, z. B. imagecreatetruecolor(), zurückgegeben wurde.

size

The font size to use in points.

angle

The angle in degrees, with 0 degrees being left-to-right reading text. Higher values represent a counter-clockwise rotation. For example, a value of 90 would result in bottom-to-top reading text.

x

The coordinates given by x and y will define the basepoint of the first character (roughly the lower-left corner of the character). This is different from the imagestring(), where x and y define the upper-left corner of the first character. For example, "top left" is 0, 0.

y

The y-ordinate. This sets the position of the fonts baseline, not the very bottom of the character.

color

The index of the desired color for the text, see imagecolorexact().

font_filename

The path to the TrueType font you wish to use.

Depending on which version of the GD library PHP is using, when font_filename does not begin with a leading / then .ttf will be appended to the filename and the library will attempt to search for that filename along a library-defined font path.

In many cases where a font resides in the same directory as the script using it the following trick will alleviate any include problems.

<?php
// Set the environment variable for GD
putenv('GDFONTPATH=' . realpath('.'));

// Name the font to be used (note the lack of the .ttf extension)
$font = 'SomeFont';
?>
text

Text to be inserted into image.

options

Possible array indexes for options
KeyTypeMeaning
linespacingfloatDefines drawing linespacing

Rückgabewerte

This function returns an array defining the four points of the box, starting in the lower left and moving counter-clockwise:

0lower left x-coordinate
1lower left y-coordinate
2lower right x-coordinate
3lower right y-coordinate
4upper right x-coordinate
5upper right y-coordinate
6upper left x-coordinate
7upper left y-coordinate

On failure, false is returned.

Beispiele

Beispiel #1 imagefttext() example

<?php
// Create a 300x100 image
$im = imagecreatetruecolor(300, 100);
$red = imagecolorallocate($im, 0xFF, 0x00, 0x00);
$black = imagecolorallocate($im, 0x00, 0x00, 0x00);

// Make the background red
imagefilledrectangle($im, 0, 0, 299, 99, $red);

// Path to our ttf font file
$font_file = './arial.ttf';

// Draw the text 'PHP Manual' using font size 13
imagefttext($im, 13, 0, 105, 55, $black, $font_file, 'PHP Manual');

// Output image to the browser
header('Content-Type: image/png');

imagepng($im);
imagedestroy($im);
?>
