imagepsbbox — Give the bounding box of a text rectangle using PostScript Type1 fonts

警告

この機能は PHP 7.0.0 で 削除 されました。

### 説明

imagepsbbox ( string `$text` , resource `$font` , int `$size` ) : array
imagepsbbox ( string `$text` , resource `$font` , int `$size` , int `$space` , int `$tightness` , float `$angle` ) : array

Gives the bounding box of a text rectangle using PostScript Type1 fonts.

The bounding box is calculated using information available from character metrics, and unfortunately tends to differ slightly from the results achieved by actually rasterizing the text. If the angle is 0 degrees, you can expect the text to need 1 pixel more to every direction.

### パラメータ

`text`

  The text to be written.

`font_index`

  imagepsloadfont() により返されるフォントリソース

`size`

  `size` is expressed in pixels.

`space`

  Allows you to change the default value of a space in a font. This amount is added to the normal value and can also be negative. Expressed in character space units, where 1 unit is 1/1000th of an em-square.

`tightness`

  `tightness` allows you to control the amount of white space between characters. This amount is added to the normal character width and can also be negative. Expressed in character space units, where 1 unit is 1/1000th of an em-square.

`angle`

  `angle` is in degrees.

### 返り値

Returns an array containing the following elements:

0 | left x-coordinate
1 | upper y-coordinate
2 | right x-coordinate
3 | lower y-coordinate

### 例

例1 imagepsbbox() usage

`<?php
// Create image handle
$im = imagecreatetruecolor(200, 200);
// Allocate colors
$black = imagecolorallocate($im, 0, 0, 0);
$white = imagecolorallocate($im, 255, 255, 255);
// Load the PostScript Font
$font = imagepsloadfont('font.pfm');
// Make a bounding box for the font
$bbox = imagepsbbox('Sample text is simple', $font, 12);
// Define our X and Y cordinates
$x = ($bbox[2] / 2) - 10;
$y = ($bbox[3] / 2) - 10;
// Write the font to the image
imagepstext($im, 'Sample text is simple', $font, 12, $black, $white, $x, $y);
// Output and free memory
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>`
