    Load B64 images

    Hi all,

    I need to apply a Base64 encoded image (it is downloaded from my site) to a Gideros Texture or Bitmap class. Is that possible? I have found a bit slow lua decoder but I cannot apply it to any of the Gideros availble classes since it is in raw data format after the decoding.

      @brigosx look at the Image Loader example in the Networking section in Gideros IDE, where it downloads raw image saves it and uses it.
      You can do the same. You can save the raw data as :
      --decoding some base64 encoded data with your lua decoder
local rawdata = decode(base64encodeddata)
 
--save raw data as image
local out = io.open("|D|image.png", "wb")
out:write(rawdata)
out:close()
 
--use it as texture
local b = Bitmap.new(Texture.new("|D|image.png"))
b:setAnchorPoint(0.5, 0.5)
b:setPosition(160, 240)
stage:addChild(b)

      Thanks for your immidiate response ar2rsawseen. Actually the problem seems to be the Lua base64 decoder. Can you propose me of a good one because the one I found on the net has bugs and is very slow.

      Haven't used any, so can't suggest any specific one.
      Better search google for http://www.google.lv/search?q=Base64+lua

      Whell finally I found a good one at the following URL (search for "Base64 in less code"):

      It is a bit slow for image files decoding but with the use of a coroutine I managed to overcome the pausing of Gideros player.

      I have attached the library in that post for anyone that may be interested in.
