GAE Go image optimizer

Go package for automatically optimizing images uploaded to Google App Engine blobstore. This reduces file size of images and, thus, reducing download times and saving you dollars.

Features:

Files are converted to JPEG format.
Compression rate is changable.
- (highly compressed) 0 --> 100 (not much compressed)
- Defaults to 75 (compressed but not visually noticable).
Change image dimensions.
- This value is the largest allowed dimension for the images.
- 0 = unlimited / no change.
- Defaults to 0.
Leaves other kind of blobs untouched
Returns the same values as blobstore.ParseUploads()

Usage

  import "github.com/tomihiltunen/gae-go-image-optimizer"
  
  func urlPathHandler(w http.ResponseWriter, r *http.Request) {
    // Create options
    o := optimg.NewCompressionOptions(r)

    // Set max size
    o.Size = 1600

    // Set quality
    o.quality = 75

    // Get the automatically optimized blobs and other values
    blobs, other, err := optimg.ParseBlobs(o)

    ...
  }
