A pure Go library for cropping images by removing borders with specified color.

## Installation

Import package with
|
|
|
|
```go

|
import "github.com/nxshock/colorcrop"

Crop white borders with 50% of thresold:
|
|
|
|
```go
|
|
croppedImage := colorcrop.Crop(
|
|
sourceImage, // for source image
|
|
color.RGBA{255, 255, 255, 255}, // crop white border

0.5) // with 50% thresold

You may use custom comparator of colors:

croppedImage := colorcrop.CropWithComparator(
|
|
sourceImage, // for source image
|
|
color.RGBA{255, 255, 255, 255}, // crop white border
|
|
0.5, // with 50% thresold
|
|
colorcrop.CmpCIE76) // using CIE76 standart for defining color difference
|
|
```
