Like this:
local pixels = { 0,50,210,40,40,40,40,40,40, ...} -- format RRRRR...
GGGGG... BBBB... and bottom-up orientation
local image = im.ImageCreate(width, height, im.RGB, im.BYTE)
image:SetPixels(pixels)
or
local pixels = { 0,50,210,40,40,40,40,40,40, ...} -- format RRRRR...
GGGGG... BBBB... AAAA... and bottom-up orientation
local image = im.ImageCreate(width, height, im.RGB, im.BYTE)
image.AddAlpha()
image:SetPixels(pixels)
To simplify this I added IupImageToImImage to SVN.

Scuri
