Notes

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

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 <syntaxhighlight lang="lua"> 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) </source>
