画像の縦横比を崩さずにリサイズ出来るライブラリです。
画像変換処理にはSkiaSharpを利用します。
usage
ImageResizeクラスの静的メソッドResizeを呼び出します。
byte[] bytes = ImageResize.Resize("ImageFilePath", 640, 480, ResizeMode.Default);
他にもいくつかのオーバーロードがあります。
byte[] bytes1 = ImageResize.Resize(stream, 640, 480, ResizeMode.Uniform, SKColors.Blue);
byte[] bytes2 = ImageResize.Resize(byteArray, 640, 480, ResizeMode.UniformToFill, SKEncodedImageFormat.Png);
byte[] bytes3 = ImageResize.Resize("ImageFilePath", 640, 480, ResizeMode.Default, SKColors.Blue, SKEncodedImageFormat.Jpeg);
byte[] bytes4 = ImageResize.Resize(stream, 640, 480, ResizeMode.Uniform, SKColors.Blue, SKEncodedImageFormat.Webp, 100);
byte[] bytes5 = ImageResize.Resize(byteArray, 640, 480, ResizeMode.UniformToFill, SKColors.Blue, SKEncodedImageFormat.Webp, 100, SKFilterQuality.High);
Resizeメソッドのパラメータは以下のとおりです。
| args | type | description |
|---|---|---|
| source | string<br>byte[]<br>stream<br>SKCodec | 変換元画像を指定します。 |
| width | int | 横幅。<br>0を指定した場合、heightを基準に縦横比が変わらないようにします。 |
| height | int | 縦幅。<br>0を指定した場合、widthを基準に縦横比が変わらないようにします。 |
| mode | ResizeMode | リサイズモード。詳細は以下。 |
| backColor | SKColor | 背景色。Uniformで余白ができる場合に適用されます。 |
| imgFmt | SKEncodedImageFormat | 出力する画像フォーマット。<br>SkiaSharpの都合上、jpeg, png, webpのみ指定できます。 |
| quality | int | 画像出力時の品質。0～100で指定します。<br>デフォルトは90です。 |
| fq | SKFilterQuality | SkiaSharpのリサイズメソッドの処理品質。 |
ResizeMode
各モードごとの挙動は以下です。
この300(w)x300(h) の画像を 200(w)x100(h) にリサイズした画像をSampleに示します。
| ResizeMode | Description | Sample |
|---|---|---|
| Default | 何もしません。指定されたサイズ通りに画像の伸縮が発生します。 |  |
| Uniform | 縦横比を維持したままリサイズします。<br>元画像と縦横比が異なる場合は余白が出来ます。 |  |
| UniformToFill | 縦横比を維持したままリサイズします。<br>元画像と縦横比が異なる場合は一部が欠落します。 |  |
※WPF/XAMLのStretch列挙型をイメージするとわかりやすいかも知れません。
