# 大小调整策略和宽高比
<a name="aspect-ratios"></a>

您选择的**大小调整策略**会影响 Elastic Transcoder 对您的输出图像的缩放，如下表所示。


| 大小调整策略 | 可能会放大输出图像 | 当填充策略为“Pad”时，可能会填充输出图像 | 输出图像可能具有与输入图像不同的像素宽高比 | 可能会裁切输出图像 | 
| --- | --- | --- | --- | --- | 
| **适应** | 支持 | 是 |   |   | 
| **填充** | 支持 |   |   | 是 | 
| **拉伸** | 支持 |   | 是 |   | 
| **保持** |   | 支持 |   | 是 | 
| **ShrinkToFit** |   | 是 |   |   | 
| **ShrinkToFill** |   | 是 |   | 是 | 

## 宽高比缩略图
<a name="ratio-thumbnails"></a>

下表展示了**大小调整策略**、**填充策略**、**最大高度**和**最大宽度**之间如何相互影响，以改变输出图像。

+ [填充](#fill-ratio)
+ [拉伸](#stretch-ratio)
+ [保持](#keep-ratio)
+ [缩小以适应](#shrink-to-fit-ratio)
+ [缩小以填充](#shrink-to-fill-ratio)

### 适应
<a name="fit-ratio"></a>

如果您为**大小调整策略**选择**适应**，则 Elastic Transcoder 会对您的输入文件进行缩放，直到它可以放进输出图像的尺寸里，而不超出输出图像的尺寸。

例如，如果您的输入文件为 `200` x `200` 像素，而您希望获得一个 `300` x `400` 像素的输出图像，则 Elastic Transcoder 会将文件大小增加至 `300` x `300` 像素，并在文件两侧应用填充策略。如果您为**填充策略**选择**未填充**，则 Elastic Transcoder 会返回 `300` x `300` 像素的文件作为输出。如果您选择**已填充**，则 Elastic Transcoder 会在输出的两侧各增加 `50` 像素的填充，然后返回一个 `300` x `400` 像素的文件。

### 填充
<a name="fill-ratio"></a>

如果您为**大小调整策略**选择**适应**，则 Elastic Transcoder 会对您的输入文件进行缩放，直到它可以填满输出图像的尺寸，并对超出输出图像尺寸的部分进行裁切。

例如，如果您的输入文件为 `200` x `200` 像素，而您希望获得一个 `300` x `400` 像素的输出图像，则 Elastic Transcoder 会将输入大小增加至 `400` x `400` 像素，从顶部和底部裁切 `50` 像素，然后返回 `300` x `400` 像素的文件。Elastic Transcoder 不会为**填充**策略使用填充。

### 拉伸
<a name="stretch-ratio"></a>

如果您为**大小调整策略**选择**拉伸**，则 Elastic Transcoder 会拉伸或缩小输入文件，直到它与输出文件的尺寸相匹配。

例如，如果您的输入文件为 `200` x `200` 像素，而您希望获得一个 `300` x `400` 像素的输出图像，则 Elastic Transcoder 会将输入大小增加至 `300` x `400` 像素，导致输出图像的比例发生扭曲。Elastic Transcoder 不会为**拉伸**策略使用填充或裁切。

### 保持
<a name="keep-ratio"></a>

如果您为**大小调整策略**选择**保持**，则 Elastic Transcoder 不会缩放您的输入文件。Elastic Transcoder 会裁切或填充输入文件，直到它与输出图像的尺寸相匹配。

例如，如果您的输入文件为 `400` x `200` 像素，而您希望获得一个 `300` x `300` 像素的输出图像，则 Elastic Transcoder 会从顶部和底部裁掉 `100` 像素，并在两侧应用填充策略。如果您为**填充策略**选择**未填充**，则 Elastic Transcoder 会返回 `300` x `200` 像素的输出文件。如果您选择**已填充**，则 Elastic Transcoder 会返回 `300` x `300` 像素的文件。

### 缩小以适应
<a name="shrink-to-fit-ratio"></a>

如果您为**大小调整策略**选择**缩小以适应**，则 Elastic Transcoder 会缩小您的输入文件的大小，直到它可以放进输出文件的尺寸里，而不超出输出图像的尺寸。如果您的输入文件小于输出图像，则 Elastic Transcoder 不会增加文件大小。

例如，如果您的输入文件为 `400` x `400` 像素，而您希望获得一个 `200` x `300` 像素的输出图像，则 Elastic Transcoder 会将输入缩小至 `200` x `200` 像素，然后应用填充策略。如果您为**填充策略**选择**未填充**，则 Elastic Transcoder 会返回 `200` x `200` 像素的文件作为输出。如果您选择**已填充**，则 Elastic Transcoder 会在输出的两侧各增加 `50` 像素的填充，然后返回一个 `300` x `300` 像素的文件。

### 缩小以填充
<a name="shrink-to-fill-ratio"></a>

如果您为**大小调整策略**选择**缩小以填充**，则 Elastic Transcoder 会缩小输入文件的大小，直到它填满输出图像的尺寸，并对不能放入输出图像内的部分进行裁切，然后应用填充策略。如果您的输出图像大于输入文件，则 Elastic Transcoder 不会增加文件大小。

例如，如果您的输入文件为 `400` x `200` 像素，而您希望获得一个 `200` x `300` 像素的输出图像，则 Elastic Transcoder 会从两侧裁切 `100` 像素，并在文件的顶部和底部应用填充策略。如果您为**填充策略**选择**未填充**，则 Elastic Transcoder 会返回 `200` x `200` 像素的输出文件。如果您选择**已填充**，则 Elastic Transcoder 会返回 `200` x `300` 像素的文件。
