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.

• 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()

  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)

    ...
