imagettftext
Name
imagettftext — Draws a string using a TrueType font.
Synopsis
array imagettftext(image, size,
angle, x, y, color, font, string);
int image: Image
identifier
int size: Font size
int angle: Angle of rotation
of text
int x: X coordinate
int y: Y coordinate
int color: Specified
color
string font: Font file
string string: String to
display
Returns
Array or FALSE on error
Description
imagettftext() relies on Freetype support being
compiled into PHP. The function draws a string on the
image in a specified TrueType font. There are several
advantages to using this function versus imagestring() : Any TrueType
font file can be used, the text can be rotated at any
angle, and the font size can be more widely varied. The
angle of rotation of the text is different from that used
by imagearc() . The
rotation point is the x and y coordinate position at the
lower-left corner of the first character. From there, the
angle goes from 0 to 360 degrees up and around to the
left in a counterclockwise direction. The function
returns an eight-element array consisting of the x and y
coordinates of the bounding box (the rectangle enclosing
the rendered text). The coordinates are independent of
the angle of rotation of the text. Thus, if the image is
rotated, the coordinates are taken as the upper-left
corner of the box around the text relevant to the text,
not the upper-left corner of the rotated string.
The array returned from this function contains the
bounding coordinates of the text. For more details, see
imagettfbbox() .
Example
Example 447. Display text
header("Content-type: image/png");
$im = imagecreate(200, 200);
$green = imagecolorallocate($im, 0, 255, 0);
$red = imagecolorallocate($im, 255, 0, 0);
imagefill($im, 0, 0, $green);
imagettftext($im, 30, 45, 50, 150, $red, "verdana.ttf", "SAMPLE!");
imagepng($im);
imagedestroy($im);
