示例

AsciiHexadecimalToBinaryInputStream

此类从从属输入流中读取 ascii 十六进制字节并将它们转换为二进制字节。两个十六进制字节转换为一个二进制字节。

<?php

require_once __DIR__.'/vendor/autoload.php';

use ZerusTech\Component\IO\Stream\Input\StringInputStream;
use ZerusTech\Component\Postscript\Font\TypeOne\Stream\Input;

$in = new StringInputStream('68656c6c6f');

$input = new Input\AsciiHexadecimalToBinaryInputStream($in);

$count = $input->read($string, 5); // reads upto 5 binary bytes from the stream. 

printf("%d bytes read: %s\n", $count, $string); // 'hello'

BinaryToAsciiHexadecimalInputStream

此类从从属输入流中读取二进制字节并将它们转换为 ascii 十六进制字节。一个二进制字节转换为两个 ascii 十六进制字节。

<?php

require_once __DIR__.'/vendor/autoload.php';

use ZerusTech\Component\Postscript\Font\TypeOne\Stream\Input;

$in = new StringInputStream('hello');

$input = new Input\BinaryToAsciiHexadecimalInputStream($in);

printf("%d bytes read: %s\n", $count, $string); // '68656C6C6F'

AsciiHexadecimalFormatInputStream

// Formats hexadecimal string as follows:
// Current column: 0
// Columns per line: 5
$input = new Input\AsciiHexadecimalFormatInputStream($in, 0, 5);

// reads upto 33 hex bytes, including line feeds from the stream.
