The font size. Depending on your version of GD, this should be
specified as the pixel size (GD1) or point size (GD2).
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 color index. Using the negative of a color index has
the effect of turning off antialiasing.
See imagecolorallocate().
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'; ?>
text
The text string.
May include decimal numeric character references (of the form:
€) to access characters in a font beyond position 127.
Strings in UTF-8 encoding can be passed directly.
If a character is used in the string which is not supported by the
font, a hollow rectangle will replace the character.
imagettftext() returns an array with 8
elements representing four points making the bounding box of the
text. The order of the points is lower left, lower right, upper
right, upper left. The points are relative to the text
regardless of the angle, so "upper left" means in the top
left-hand corner when you see the text horizontally.
Example 1. imagettftext() example
This example script will produce a white PNG 400x30 pixels, with
the words "Testing..." in black (with grey shadow), in the font Arial.
<?php // Set the content-type header("Content-type: image/png");
// Create the image $im = imagecreatetruecolor(400, 30);
