# Summary
Forked version of killme2008's [clj.qrgen](https://github.com/killme2008/clj.qrgen) - clojure wrapper over [QRGen](https://github.com/kenglxn/QRGen) with iCal scheme added.
## Usage
```clojure
(use 'qrgen)
```
Create a QRCode from a text then save as a temporary file:
```clojure
(as-file (from "hello world"))
```
Created with options:
```clojure
;; override size and image type
(from "hello world" :size [250 250] :image-type JPG)
;; supply charset hint to ZXING
(from "hello world" :charset "utf-8")
;; supply error correction level hint to ZXING
(from "hello world" :correction L)
;; supply any hint to ZXING
(from "hello world" :hint {CHARACTER_SET "utf-8"})
```
Encode contact data as vcard using defaults:
```clojure
(from (vcard "John Doe"
:email "[email protected]"
:address "John Doe Street 1, 5678 Doestown"
:title "Mister"
:company "John Doe Inc."
:phonenumber "1234"
:website "www.example.org"))
```
same with ical:
```clojure
(from (ical "20170324T193000Z" ;; DTSTART
"20170324T194000Z" ;; DTEND
:organizer "Foo"
:summary "Birthday party"
:location "Coffee Bar"
:description "Bring sandwiches")
```
As InputStream( as ring response):
```clojure
(as-input-stream (from "hello world"))
```
As OutputStream:
```clojure
(as-output-stream (from "hello world"))
```
As byte array:
```clojure
(as-bytes (from "hello world"))
```
Suppy own file name:
```clojure
(as-file (from "hello world") "QRCode.png")
```
Work with `clojure.java.io`:
```clojure
(require '[clojure.java.io :as io])
(io/file (from "hello world"))
(io/output-stream (from "hello world"))
(io/input-stream (from "hello world"))
(io/copy (io/file (from "hello world")) a-output-stream)
```
