很多站长朋友们都不太清楚php制作圆角png，今天小编就来给大家整理php制作圆角png，希望对各位有所帮助，具体内容如下：
本文目录一览： 1、 easyphpthumbnail，phpthumb哪 个更好 2、 如何制作圆角图片 3、 utf-8 转换圆角怎么实现? 用php写的 easyphpthumbnail，phpthumb哪 个更好EasyPHPThumbnail类可以处理图像和PHP生成缩略图支持GIF、JPG和PNG。这个类是免费的，基于100％的PHP，可用于PHP4（4.3.11以上）和PHP5，易于使用，并提供了超过60的功能操作：
提供的功能包括：调整大小，裁剪，旋转，翻转，另存为，阴影，水印，文字，边框，锐化，模糊，水波纹，反射镜，透视，动画，置换贴图和更多！
使用简介
1、基本使用
<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Createthumb('gfx/image.jpg');
?>
2、动态显示指定大小图片
<?php
include_once('inc/easyphpthumbnail.class.php');
// Your full path to the images
$dir = str_replace(chr(92),chr(47),getcwd()) . '/gfx/';
// Create the thumbnail
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Createthumb($dir . 'img.jpg');
?>
3、生成静态多张本地图片
<?php
include_once('inc/easyphpthumbnail.class.php');
// Your full path to the images
$dir = str_replace(chr(92),chr(47),getcwd()) . '/gfx/';
$dir_thumbs = str_replace(chr(92),chr(47),getcwd()) . '/thumbs/';
if(!is_dir($dir_thumbs)) mkdir($dir_thumbs,0777);
// Create the thumbnail
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 600;
$thumb -> Copyrighttext = 'SCUTEPHP.COM';
$thumb -> Copyrightposition = '50% 90%';
$thumb -> Copyrightfonttype = $dir . 'handwriting.ttf';
$thumb -> Copyrightfontsize = 30;
$thumb -> Copyrighttextcolor = '#FFFFFF';
$thumb -> Chmodlevel = '0755';
$thumb -> Thumblocation = $dir_thumbs;
$thumb -> Thumbsaveas = 'jpg';
$thumb -> Thumbprefix = '120px_thumb_';
$thumb -> Createthumb(array($dir . '69.jpg', $dir . '70.jpg'), 'file');
?>
4、图片大小百分比调整及图片旋转
<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 50;
$thumb -> Rotate = 90;//指定度数旋转
//$thumb -> Fliphorizontal = true; //水平轴旋转
//$thumb -> Flipvertical = true; //垂直轴旋转
$thumb -> Percentage = true;
$thumb -> Createthumb('gfx/image.jpg');
?>
Thumbsize默认是px像素单位，然而要用百分比的话可以设置Percentage属性为ture，Rotate属性设置顺时针旋转度数。
5、给缩略图增加背景阴影
<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Backgroundcolor = '#D0DEEE';

include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Clipcorner = array(2,15,0,0,1,1,0);
$thumb -> Createthumb('gfx/image.jpg');
?>
Clipcorner属性的7个参数含义
[0]: 0=关闭 1=直角 2=圆角
[1]: 裁剪比例
[2]: 随机 - 0=关闭 1=开启
[3]: 左上 - 0=关闭 1=开启
[4]: 左下 - 0=关闭 1=开启
[5]: 右上 - 0=关闭 1=开启
[6]: 右下 - 0=关闭 1=开启

$thumb = new easyphpthumbnail;
$thumb -> Backgroundcolor = '#0000FF';
$thumb -> Clipcorner = array(2,15,0,1,1,1,1);
$thumb -> Maketransparent = array(1,1,'#0000FF',30);
$thumb -> Createthumb('gfx/image.jpg');
?>
8、给缩略图增加框架效果
<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#FFFFFF';
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Shadow = true;
$thumb -> Createthumb('gfx/image.jpg');
?>
9、给缩略图增加经典相框效果
<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#FFFFFF';
$thumb -> Backgroundcolor = '#D0DEEE';
$thumb -> Shadow = true;
$thumb -> Binder = true;
$thumb -> Binderspacing = 8;
$thumb -> Clipcorner = array(2,15,0,1,1,1,0);
$thumb -> Createthumb('gfx/image.jpg');
?>
10、给缩略图增加水印效果
<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#00000';
$thumb -> Backgroundcolor = '#000000';
$thumb -> Clipcorner = array(2,15,0,1,1,1,1);
$thumb -> Watermarkpng = 'watermark.png';
$thumb -> Watermarkposition = '50% 50%';
$thumb -> Watermarktransparency = 70;
$thumb -> Createthumb('gfx/image.jpg');
?>
11、给缩略图增加短文本及相框
<?php
include_once('inc/easyphpthumbnail.class.php');
$thumb = new easyphpthumbnail;
$thumb -> Thumbsize = 300;
$thumb -> Framewidth = 10;
$thumb -> Framecolor = '#00000';
$thumb -> Borderpng = 'border.png';

如何制作圆角图片可以直接用这个在线图片转圆角图片的工具吧，直接设置一下圆角的数值，马上就能出结果。还能单独设置图片四个角是否需要变成圆角。图片背景是透明的没有白边，正好符合你要求。在线生成圆角图片,PNG|JPG图片转圆角工具
生成圆角图片工具使用步骤：
一、首先选定一张照片，通过改变圆角大小的数值，下方会显示照片转换效果的实时预览，默认生成的圆角为60px。
二、可以通过多选框单独选择图片需要被转换成圆角的角，默认是图片的四个角都会被转换成圆角。
三、图片预览显示的是转换后的缩略图，而下载时候是转换生成的原始大小和原始清晰度的图片。
四、因为jpg等格式的图片不支持透明背景，所以如果选定的照片原始格式为jpg等，会自动将照片转换为png格式，那么在下载时png照片占用的存储空间可能会显著增大。
五、如果圆角设置过大，可能会造成不可预计的转换结果，应当在合理范围内设置图片圆角的大小。
utf-8 转换圆角怎么实现? 用php写的<?php
echo ' web-root = '.$_SERVER['DOCUMENT_ROOT'].'<br>';
echo ' current-file = '.__FILE__.'<br>';
echo ' current-dir = '.dirname(__FILE__).'<br>';
echo ' http-root = '.$_SERVER['HTTP_HOST'].'<br>';
echo ' web-position = '.$_SERVER['PHP_SELF'].'<br>';
$file='c:/webroot/index.php';
echo ' file-position = '.$file.'<br>';
$fileWebAddress='http://'.str_replace($_SERVER['DOCUMENT_ROOT'],$_SERVER['HTTP_HOST'],$file);
echo ' file-web-position = '.$fileWebAddress.'<br>';
?>
