ImageTTFTextPHP ManualPrevNextImageTTFTextImageTTFText -- write text to the image using TrueType fontsDescriptionarray ImageTTFText(int im, int size, int angle, int x, int y, int col, string fontfile, string text);
ImageTTFText draws the string text in the
image identified by im, starting at
coordinates x,y (top left is 0,0), at an
angle of angle in color
col, using the TrueType font file
identified by fontfile.
The coordinates given by
x,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,y define the
upper-right corner of the first character.
angle is in degrees, with 0 degrees being
left-to-right reading text (3 o'clock direction), and higher
values representing a counter-clockwise rotation. (i.e., a value
of 90 would result in bottom-to-top reading text).
fontfile is the path to the TrueType font
you wish to use.
text is the text string which may include
UTF-8 character sequences (of the form: { ) to access
characters in a font beyond the first 255.
col is the color index. Using the
negative of a color index has the effect of turning off
antialiasing.
ImageTTFText() returns an array with 8
elements representing four points making the bounding box of the
text. The order of the points is upper left, upper right, lower
right, lower 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 horizontallty.
This example script will produce a black GIF 400x30 pixels, with
the words "Testing..." in white in the font Arial.
Example 1. ImageTTFText 1
2 <?php
3 Header("Content-type: image/gif");
4 $im = imagecreate(400,30);
5 $black = ImageColorAllocate($im, 0,0,0);
6 $white = ImageColorAllocate($im, 255,255,255);
7 ImageTTFText($im, 20, 0, 10, 20, $white, "/path/arial.ttf", "Testing... Omega: Ω");
8 ImageGif($im);
9 ImageDestroy($im);
