image
Eine von den verschiedenen Erzeugungsfunktionen wie imagecreatetruecolor() gelieferte Grafikressource.
sizeThe font size to use in points.
angleThe 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.
yThe y-ordinate. This sets the position of the fonts baseline, not the very bottom of the character.
colorThe index of the desired color for the text, see imagecolorexact().
fontfileThe path to the TrueType font you wish to use.
Depending on which version of the GD library PHP is using, when
fontfile 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.
When using versions of the GD library lower than 2.0.18, a space character, rather than a semicolon, was used as the 'path separator' for different font files. Unintentional use of this feature will result in the warning message: Warning: Could not find/open font. For these affected versions, the only solution is moving the font to a path which does not contain spaces.
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 enviroment variable for GD
putenv('GDFONTPATH=' . realpath('.'));
// Name the font to be used (note the lack of the .ttf extension)
$font = 'SomeFont';
?>
textText to be inserted into image.
extrainfo
| Key | Type | Meaning |
|---|---|---|
| linespacing | float | Defines drawing linespacing |
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 |
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);
?>
