How to apply artistic filters and stylize images in Go?

To apply artistic filters and stylize images in Go, you can use various libraries and packages available. One popular library for image processing in Go is the "github.com/disintegration/imaging" package.

Here's an example of how you can use this package to apply artistic filters and stylize images:

1. First, install the package using the following command:

   go get -u github.com/disintegration/imaging

2. Import the necessary packages in your Go code:

   import ( "github.com/disintegration/imaging" "image" )

3. Load the image you want to stylize:

   srcImage, err := imaging.Open("path/to/source/image.jpg") if err != nil { // handle error }

4. Apply filters and stylize the image using the available functions:

   // Apply Sepia filter sepiaImage := imaging.AdjustFunc(srcImage, func(c color.NRGBA) color.NRGBA { r, g, b, _ := c.RGBA() red := float64(r) green := float64(g) blue := float64(b) newRed := 0.393*red + 0.769*green + 0.189*blue newGreen := 0.349*red + 0.686*green + 0.168*blue newBlue := 0.272*red + 0.534*green + 0.131*blue return color.NRGBA{R: uint8(newRed), G: uint8(newGreen), B: uint8(newBlue), A: c.A} }) // Apply Grayscale filter grayscaleImage := imaging.Grayscale(srcImage) // Apply Gaussian blur blurredImage := imaging.Blur(srcImage, 5.0)

5. Save the resulting stylized images:

   err = imaging.Save(sepiaImage, "path/to/save/sepia_image.jpg") if err != nil { // handle error } err = imaging.Save(grayscaleImage, "path/to/save/grayscale_image.jpg") if err != nil { // handle error } err = imaging.Save(blurredImage, "path/to/save/blurred_image.jpg") if err != nil { // handle error }

Remember to handle any errors that may occur during image loading, stylization, or saving. Additionally, you can explore other available functions and adjustments provided by the "github.com/disintegration/imaging" package to apply various filters and stylize images according to your requirements.
