Supported platforms:
Available since: Gideros 2016.1

Description

• Get files from file system (desktop only)
• Get image from Camera, gallery or file system (mobile and desktop)
• Resize image
• Make copy of an image
• Take screenshots
• Play videos (for cutscenes)
• Manipulate pictures (getting/setting pixels, flood fill)
• And much more...

require "media"

Notes

By resizing image you will actually resize the file of the image, so there is no going back to upscale it later.

getPicture method gives you copies of the image, so you won't harm the original.

The dimensions when resizing are all actual dimensions of the image and not logical dimensions in your project.

Example

Saves a picture on your phone or on your pc.

require "media"
 
-- draw your gfx
local source = Pixel.new(0xff00ff, 1, 128, 128)
-- create a render target and draw to it
local rt = RenderTarget.new(source:getWidth(), source:getHeight())
rt:draw(source)
-- save your render target to gideros documents folder
local myfilepath = "|D|mysavedpicture2.png"
rt:save(myfilepath)
-- create a new media and save your gfx
local media = Media.new(myfilepath)
-- android saved path = internal storage/pictures !!! NEED permission write external storage !!!
mediamanager:postPicture(myfilepath)
 
-- show your gfx on stage
local mybmprt = Bitmap.new(Texture.new(myfilepath))
mybmprt:setPosition(64, 64)
stage:addChild(mybmprt)
