Resize creates a scaled image with new dimensions (`width`, `height`) using the interpolation function `interp`. The resize package provides 2 functions:
If either `width` or `height` is set to 0, it will be set to an aspect ratio preserving value.
* `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 ```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
resize.Thumbnail(maxWidth, maxHeight uint, img image.Image, interp resize.InterpolationFunction) image.Image
``` ```
The provided interpolation functions are (from fast to slow execution time) The provided interpolation functions are (from fast to slow execution time)
