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
xandywill define the basepoint of the first character (roughly the lower-left corner of the character). This is different from the imagestring(), wherexandydefine 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_filenamedoes not begin with a leading/then.ttfwill 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 optionsKey Type Meaning linespacingfloat Defines drawing linespacing
Rückgabewerte
This function returns an array defining the four points of the box, starting in the lower left and moving counter-clockwise:
| 0 | lower left x-coordinate |
| 1 | lower left y-coordinate |
| 2 | lower right x-coordinate |
| 3 | lower right y-coordinate |
| 4 | upper right x-coordinate |
| 5 | upper right y-coordinate |
| 6 | upper left x-coordinate |
| 7 | upper left y-coordinate |
On failure, false is returned.

<?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);
