README

正在进行中

此模块仍在开发中。此模块存在是因为 SilverStripe 缺少功能，一旦 Image 重新实现，其 API 可能会更改或完全过时。

当前功能

• SetCroppedSize - 更一致的名字，允许指定裁剪原点
• SetMaxRatioSize - 如果图像太大，则只使用 SetRatioSize
• SetQuality - 设置 jpeg 质量
• SetGreyscale - 灰度图像
• GetAsDataURI - 返回图像作为 base64 数据 URI 字符串

安装

要求

• php GD (ImagickBackend 尚未实现)

安装模块

1. 使用 composer 安装模块或下载并放置在您的项目文件夹中
2. 运行 ?flush=1

使用方法

$Image.SetCroppedSize(300, 300, 'left', 'top') <!-- image is cropped to 300x300 from the left top -->
$Image.SetMaxRatioSize(1000, 1000) <!-- returns an image of 1000x1000 or smaller -->
$Image.SetQuality(75) <!-- only for jpeg, returns an image with quality set to 75 -->
$Image.SetGreyscale <!-- returns a grey scale version of the image -->
<img alt="" src="$Image.GetAsDataURI" />

<!-- as with all SilverStripe image methods, they can be chained: -->
$Image.SetMaxRatioSize(1000, 1000).SetQuality(75)
<img alt="" src="$Image.SetCroppedSize(300, 300).SetQuality(50).getURL" />    
<img alt="" src="$Image.SetCroppedSize(300, 300).SetQuality(50).GetAsDataURI" />    
<% with $Image.SetMaxRatioSize(1000, 1000) %>
	<div style="background-image: url('$SetQuality(75).SetGreyscale(50, 50, 50).getURL');
				width: {$getWidth}px; 
				height: {$getHeight}px;">
	</div>
<% end_with %>
