Can someone help me (if is possible) to retrieve an image (JPG) from an URL (http protocol).

Thanks

from the not yet done weather module
local b,HTTPERROR = self.SatMaphttp.request( self.SatMap.URL )
if HTTPERROR == 200 then -- no error
local f = assert(io.open(self.SatMap.Filename, "wb"))
local t = f:write(b)
f:close()
self.SatMapMutex:lock ()
self.SatMap.LastUpdate = win.GetElapsedSeconds ()
self.SatMapMutex:unlock ()
self:LogUpdate (self.SatMap.Product)
else
self:LogUpdate (self.SatMap.Product,"Error "..(HTTPERROR or "unknown"))
end

self.SatMaphttp.request( self.SatMap.URL )

What this object ?

I have this code:


b, HTTPERROR = self.SatMaphttp.request( 'http://myurl' )
if HTTPERROR == 200 then
print ('OK')
else
print('Error')
end

Sorry, one more question... I'm trying to convert JPG to BMP as I suspect that the function you implement only receive a BMP file (is'nt correct?)
Now, I found a function win.ConvertImageFormat, what does this function do? and what are the parameters?

Thsnks any help.

http=require("socket.http")

local b,HTTPERROR = http.request(URL )
if HTTPERROR == 200 then -- no error
local f = assert(io.open(self.SatMap.Filename, "wb"))
local t = f:write(b)
f:close()
end


try this instead.

see the lua windows function example gml on how to use the convert image. the function above will download any type of file.
