php 한글 메뉴얼 도움말 검색 사이트 Give the bounding box of a text rectangle using PostScript Type1 fonts [function.imagepsbbox]

설명

array imagepsbbox ( string $text , resource $font , int $size )

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

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.

Warning

This function was REMOVED in PHP 7.0.0.

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.

Example #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
