Supported platforms:
Available since: Gideros 2016.1

Description

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

Examples

Example 1.

--require plugin
require "media"

-- is camera available
print(mediamanager:isCameraAvailable())

-- take screenshot (no permission needed)
mediamanager:takeScreenshot()

-- get picture from gallery (*need read permission*)
mediamanager:getPicture()

-- save picture to sdcard/pictures folder (*need write permission*)
mediamanager:postPicture("gfx/ball.png")

Example 2.

require "media"
mediamanager:addEventListener(Event.MEDIA_RECEIVE, function(e)
    local media = Media.new(e.path)
    media:resize(200, 200)
    print(media:getPixel(1, 1))
    for x = 50, 100 do
        for y = 50, 100 do
            media:setPixel(x, y, 255, 0, 0, 0.5)
        end
    end
    media:save()
    local bmp = Bitmap.new(Texture.new(e.path, true))
    stage:addChild(bmp)
end)

if mediamanager:isCameraAvailable() then
    mediamanager:takePicture()
else
    mediamanager:getPicture()
end

Example 3. Save 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)

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.

Methods mediamanager:deleteFile(path) deletes file at provided path mediamanager:getPicture selects picture from gallery mediamanager:isCameraAvailable returns true if you can get picture from camera mediamanager:playVideo(path, force) plays video file in given path (bool force to watch till the end, or quit playing on tap) mediamanager:postPicture(path) adds picture from given path to gallery (or opens save file dialog on pc) mediamanager:takePicture allows user to provide picture input from camera mediamanager:takeScreenshot captures a screenshot of the app Media.new(path) creates a new Media object with provided image Media.new(width, height) creates a blank Media object with provided dimensions Media:getPath() returns the path that was used to create the media Media:getHeight() returns the height of the image Media:getWidth() returns the width of the image Media:getPixel(x, y) returns r, g, b, a values of pixel at x,y coordinate 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:resizeWidth(newWidth, fixed) resizes image width Media:resizeHeight(newHeight, fixed) resizes image height Media:resize(newWidth, newHeight, fixed, crop) resizes image width and height Media:crop(x, y, width, height) crops an image Media:copy(destination) makes a copy of an image Media:save() saves the changes made to file Media:setRotation(angle) rotates image Media:getRotation() returns current rotation Media:flipHorizontal() flips image horizontally Media:flipVertical() flips image vertically Media:drawImage(x, y, media, alpha) draws another image on current one TO DO! Media:drawText(x, y, text, hexColor, fontSize, alpha) -- draw a text at provided coorindates with provided settings Media:drawLine(x0, y0, x1, y0, hexColor, alpha, blendAlpha) -- draw a line from x0,y0 to x1,y1 with provided settings Media:drawFill(x, y, width, height, hexColor, alpha, blendAlpha) -- draw filled rectangle at x,y position with width,height dimensions and with provided settings Media:floodFill(x, y, hexColor, alpha, tolerance, blendAlpha) -- fill area with provided color based on tolerance to other colors Media:trim(hexColor) -- trim image by provided background color, if color is not provided, uses top left pixel to crop

Events Event.MEDIA_RECEIVE (e.path) -- path to image Event.MEDIA_CANCEL --user cancelled media input Event.VIDEO_COMPLETE --user completed watching video Constants
