Re: [Imtoolkit-users] Draw line on a image

[Milind G. <mil...@gm...>]

Tried this:

local crd = im.ImageCreate(2200, 1700, im.RGB, im.BYTE)
    im.ProcessRenderConstant(crd, {255, 255, 255})
canvas =
cd.CreateCanvas(cd.IMAGERGB,tostring(crd:Width()).."x"..tostring(crd:Height()).."
0x"..tostring(crd[0]):match("imImageChannel%((.-)%)").."
0x"..tostring(crd[1]):match("imImageChannel%((.-)%)").."
0x"..tostring(crd[2]):match("imImageChannel%((.-)%)"))
canvas:LineStyle(cd.DASHED)
canvas:Line(10, 10, 50, 50)
cd.KillCanvas(canvas)
im.FileImageSave("a.png", "PNG", crd)

But did not work just a white image
