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。

<br> <br>

ResizeMode

ResizeMode description
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。
