Description
Sharing a piece of data with an external app.
(bool) = Share.share(mimeType,data)
This invokes the platform default sharing dialog, allowing to save, print, send, share, etc.
Supported MIME types:
- "text/*"
- "image/png"
- "image/jpeg"
Parameters
mimeType: (string) the MIME type of the data
data: (string) the data itself
Return values
Returns (boolean) true if data can be shared
Examples
Image from file
require "Share"
local share = Share.new()
local img = io.open("gfx/cat.jpg")
local rimg = img:read("*all")
share.share("image/jpeg", rimg) -- MIME type, data
Using a Buffer (faster than IO)
local share = require "Share"
local tex = Texture.new("gfx/cat.jpg")
local bmp = Bitmap.new(tex)
local rt = RenderTarget.new(tex:getWidth(), tex:getHeight())
rt:draw(bmp)
local buff = Buffer.new("buffer.jpg") -- create a buffer
rt:save("|B|buffer.jpg") -- write to the buffer
local bdata = buff:get()
share.share("image/jpeg", bdata) -- share buffer data
