CAMERA to Image?

Questions

Hello,
Why CAMERA is not an image?
Someone knows how to make an variable with Camera as Image?

Here’s an example. Use collectgarbage() to prevent Codea from crashing when it updates img.

displayMode(FULLSCREEN)

function setup()
end

function draw()
    background(40, 40, 50)
    img=image(CAMERA)
    collectgarbage()
    if img~=nil then
        sprite(img,WIDTH/2,HEIGHT/2)
    end
end

Why that doesn’t work???


function setup()
    
end

function draw()
    i = image(CAMERA)
    collectgarbage()
    imgCopy = i:copy(i.width/2, i.height/2, 500, 500)
end

Are you after something like this. Tap the screen to copy a section of the Camera image.

displayMode(FULLSCREEN)

function setup()
end

function draw()
    background(0)
    i = image(CAMERA)
    collectgarbage()
    if imgCopy~=nil then
        sprite(imgCopy,WIDTH/2,HEIGHT/2)
    elseif i~=nil then
        sprite(i,WIDTH/2,HEIGHT/2)
    end
end

function touched(t)
    if t.state==BEGAN then
        print(i)
        imgCopy = i:copy(i.width/2, i.height/2, 500, 500)
    end
end
