This package contains methods for images upload to the Capella

java -jar capella.jar

git clone https://github.com/codex-team/capella.scala.git
cd capella.scala
sbt compile
sbt run

import codex.capella.CapellaApi

CapellaApi.uploadUrl("https://ifmo.su/public/app/img/products/capella.png") match {
  case Left(x) => println("Result: " + x)
  case Right(x) => println("Exception: " + x)
}

CapellaApi.uploadFile("C:\\capella.jpg") match {
  case Left(x) => println("Result: " + x)
  case Right(x) => println("Exception: " + x)
}

Response object contains the following parameters: success, message, id, url

• success is true when Capella successfully saved the image
• url - special allocated URL for uploaded image. If success is false this property takes value of nil
• id – an unique image identifier which is equal to the part of the url
• message - in the case of error you will get a message.

You can apply filters to the image's URL. Currently we support the following filters:

• pixelize – render image using large colored blocks.
• crop – cover the target rectangle by the image.
• resize – scale the image.

Example of resize filter

import codex.capella.Pipeline._
import codex.capella.Filters

val url = "https://capella.pics/07d4fa39-7465-474a-9e01-15a71bb71c32"
val filteredUrl = url |> Filters.resize(700, 700)
println(filteredUrl)

// got: https://capella.pics/07d4fa39-7465-474a-9e01-15a71bb71c32/resize/700x700

You can also apply sequence of filters using pipeline operator or applyFilters method.

import codex.capella.Pipeline._
import codex.capella.Filters

val url = "https://capella.pics/07d4fa39-7465-474a-9e01-15a71bb71c32"
val filteredUrl = url |> Filters.resize(700, 700) |> Filters.crop(100, 100, (50, 50))

val filteredUrlAnother = Filters.applyFilters(url, Seq(Filters.resize(700, 700), Filters.crop(500)))

println(filteredUrlAnother)
// got: https://capella.pics/07d4fa39-7465-474a-9e01-15a71bb71c32/resize/700x700/crop/500

Currently support the following arguments

• -f/--file - upload local file
• -u/--url - upload file by URL
• -i - apply filter to the result URL

Upload local file to Capella

java -jar capella.jar --file capella.png
// output: https://capella.pics/fa10d5bc-f1e0-4527-b69d-a1b8334e7ae8

Upload file to Capella by URL

java -jar capella.jar --url https://ifmo.su/public/app/img/products/hawk.png
// output: https://capella.pics/a05702c9-ba2a-47d0-8d6c-07596588a0e5

Upload and consistently apply several filters

java -jar capella.jar --url https://ifmo.su/public/app/img/products/hawk.png -i crop:250,250
// output: https://capella.pics/bd2f6c54-b6da-4b9d-ad6b-36b089e3c470/crop/250x250

java -jar capella.jar -i crop:250,250 -i resize:300 -i pixelize:100 --url https://ifmo.su/public/app/img/products/hawk.png
// output: https://capella.pics/9cba0795-d4c9-4b43-aac8-82d7c6e3ef72/crop/250x250/resize/300/pixelize/100

If you not specify --file or --url, filters will by applied to the standard input

echo "https://capella.pics/9cba0795-d4c9-4b43-aac8-82d7c6e3ef72" | java -jar capella.jar -i crop:250,250,100,100 -i pixelize:100
// output: https://capella.pics/9cba0795-d4c9-4b43-aac8-82d7c6e3ef72/crop/250x250&100,100/pixelize/100

java -jar capella.jar --url https://ifmo.su/public/app/img/products/hawk.png | java -jar capella.jar -i pixelize:100 | java -jar capella.jar -i resize:500
// output: https://capella.pics/8d4305cf-ffd0-4d3e-8eaa-327bcc179b00/pixelize/100/resize/500
