imagefttext
(PHP 4 >= 4.0.7, PHP 5)
imagefttext — Write text to the image using fonts using FreeType 2
Description
array imagefttext
( resource $image
, float $size
, float $angle
, int $x
, int $y
, int $color
, string $fontfile
, string $text
[, array $extrainfo
] )
Parameters
-
image
-
An image resource, returned by one of the image creation functions,
such as imagecreatetruecolor().
-
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().
-
fontfile
-
The 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';
?>
