+The resize package provides 2 functions:
|
|
|
+
|
|
|
+* `resize.Resize` creates a scaled image with new dimensions (`width`, `height`) using the interpolation function `interp`.
|
|
|
+ If either `width` or `height` is set to 0, it will be set to an aspect ratio preserving value.
|
|
|
+* `resize.Thumbnail` downscales an image preserving its aspect ratio to the maximum dimensions (`maxWidth`, `maxHeight`).
|
|
|
+ It will return the original image if original sizes are smaller than the provided dimensions.
|

```go
|
|
|
-resize.Resize(width, height uint, img image.Image, interp resize.InterpolationFunction) image.Image
|
|

+resize.Resize(width, height uint, img image.Image, interp resize.InterpolationFunction) image.Image
