+
+Package imaging provides basic image manipulation functions (resize, rotate, flip, crop, etc.).
+This package is based on the standard Go image package and works best along with it.
+
+Image manipulation functions provided by the package take any image type
+that implements `image.Image` interface as an input, and return a new image of
+`*image.NRGBA` type (32bit RGBA colors, not premultiplied by alpha).
+
+## Installation
+
+Imaging requires Go version 1.2 or greater.
+
+ go get -u github.com/disintegration/imaging
+
+## Documentation
+
+http://godoc.org/github.com/disintegration/imaging
+
+## Usage examples
+
+A few usage examples can be found below. See the documentation for the full list of supported functions.
+
+### Image resizing
+```go
+// resize srcImage to size = 128x128px using the Lanczos filter
+dstImage128 := imaging.Resize(srcImage, 128, 128, imaging.Lanczos)
+
+// resize srcImage to width = 800px preserving the aspect ratio
+dstImage800 := imaging.Resize(srcImage, 800, 0, imaging.Lanczos)
+
+// scale down srcImage to fit the 800x600px bounding box
+dstImageFit := imaging.Fit(srcImage, 800, 600, imaging.Lanczos)
+
+// resize and crop the srcImage to make a 100x100px thumbnail
+dstImageThumb := imaging.Thumbnail(srcImage, 100, 100, imaging.Lanczos)
+```
+
+Imaging supports image resizing using various resampling filters. The most notable ones:
+- `NearestNeighbor` - Fastest resampling filter, no antialiasing.
+- `Box` - Simple and fast averaging filter appropriate for downscaling. When upscaling it's similar to NearestNeighbor.
+- `Linear` - Bilinear filter, smooth and reasonably fast.
+- `MitchellNetravali` - А smooth bicubic filter.
+- `CatmullRom` - A sharp bicubic filter.
+- `Gaussian` - Blurring filter that uses gaussian function, useful for noise removal.
+- `Lanczos` - High-quality resampling filter for photographic images yielding sharp results, but it's slower than cubic filters.
+
+The full list of supported filters: NearestNeighbor, Box, Linear, Hermite, MitchellNetravali, CatmullRom, BSpline, Gaussian, Lanczos, Hann, Hamming, Blackman, Bartlett, Welch, Cosine. Custom filters can be created using ResampleFilter struct.
+
+**Resampling filters comparison**
+
+Original image. Will be resized from 512x512px to 128x128px.
+
+
+
+Filter | Resize result
+---|---
+`imaging.NearestNeighbor` | 
+`imaging.Box` | 
+`imaging.Linear` | 
+`imaging.MitchellNetravali` | 
+`imaging.CatmullRom` | 
+`imaging.Gaussian` | 
+`imaging.Lanczos` | 
+
+### Gaussian Blur
+```go
+dstImage := imaging.Blur(srcImage, 0.5)
+```
+
+Sigma parameter allows to control the strength of the blurring effect.
+
+Original image | Sigma = 0.5 | Sigma = 1.5
+---|---|---
+ |  | 
+
+### Sharpening
+```go
+dstImage := imaging.Sharpen(srcImage, 0.5)
+```
+
+Uses gaussian function internally. Sigma parameter allows to control the strength of the sharpening effect.
+
+Original image | Sigma = 0.5 | Sigma = 1.5
+---|---|---
+ |  | 
+
+### Gamma correction
+```go
+dstImage := imaging.AdjustGamma(srcImage, 0.75)
+```
+
+Original image | Gamma = 0.75 | Gamma = 1.25
+---|---|---
+ |  | 
+
+### Contrast adjustment
+```go
+dstImage := imaging.AdjustContrast(srcImage, 20)
+```
+
+Original image | Contrast = 20 | Contrast = -20
+---|---|---
+ |  | 
+
+### Brightness adjustment
+```go
+dstImage := imaging.AdjustBrightness(srcImage, 20)
+```
+
+Original image | Brightness = 20 | Brightness = -20
+---|---|---
+ |  | 
+
+
+### Complete code example
+Here is the code example that loads several images, makes thumbnails of them
+and combines them together side-by-side.
+
+```go
+package main
+
+import (
+ "image"
+ "image/color"
+
+ "github.com/disintegration/imaging"
+)
+
+func main() {
+
+ // input files
+ files := []string{"01.jpg", "02.jpg", "03.jpg"}
+
+ // load images and make 100x100 thumbnails of them
+ var thumbnails []image.Image
+ for _, file := range files {
+ img, err := imaging.Open(file)
+ if err != nil {
+ panic(err)
+ }
+ thumb := imaging.Thumbnail(img, 100, 100, imaging.CatmullRom)
+ thumbnails = append(thumbnails, thumb)
+ }
+
+ // create a new blank image
+ dst := imaging.New(100*len(thumbnails), 100, color.NRGBA{0, 0, 0, 0})
+
+ // paste thumbnails into the new image side by side
+ for i, thumb := range thumbnails {
+ dst = imaging.Paste(dst, thumb, image.Pt(i*100, 0))
+ }
+
+ // save the combined image to file
+ err := imaging.Save(dst, "dst.jpg")
+ if err != nil {
+ panic(err)
+ }
+}
