# imagefttext

(PHP 4 >= 4.0.7, PHP 5)

imagefttext — Write text to the image using fonts using FreeType 2

### Описание

array imagefttext ( resource `$image` , float `$size` , float `$angle` , int `$x` , int `$y` , int `$color` , string `$fontfile` , string `$text` [, array `$extrainfo` ] )

### Список параметров

`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';
  ?>`

`text`

  Text to be inserted into image.

`extrainfo`

  Possible array indexes for `extrainfo`
  Key | Type | Meaning
  --- | --- | ---
  linespacing | float | Defines drawing linespacing

### Возвращаемые значения

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

### Примеры

Пример #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);
?>`
