Description

THIS PLUGIN IS NOT AVAILABLE FOR WINDOWS 32 BITS :-(

The Media functions wiki pages are prefixed by X_ because media is a reserved wiki word

Get/save 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"

Here is an extensive example

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

Saving 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)

Media:flipHorizontal() flips image horizontally
Media:flipVertical() flips image vertically
Media:floodFill(x, y, hexColor, alpha, tolerance, blendAlpha) flood fills current image
Media:getHeight() returns the height of the image
Media:getPath() returns the path that was used to create the media
Media:getPixel(x, y) returns r, g, b, a values of pixel at x,y coordinate
Media:getRotation() returns current rotation
Media:getWidth() returns the width of the image
Media:resize(newWidth, newHeight, fixed, crop) resizes image width and height
Media:resizeHeight(newHeight, fixed) resizes image height
Media:resizeWidth(newWidth, fixed) resizes image width
Media:save() saves the changes made to file
Media:setPixel(x, y, r, g, b, a) sets r, g, b, a values to pixel at x,y coordinate
Media:setPixel(x, y, hex, a, blendAlpha) sets hex color and alpha values to pixel at x,y coordinate
Media:setRotation(angle) rotates image
Media:trim(hexColor) trims current image

Events

Event.MEDIA_RECEIVE (e.path) path to image
