a little Bitmap reading question

[torels]

Hi there

I made this script

$string="Hello World!"&@CRLF&"The quick, brown fox Jumped over the lazy dog."&@CRLF&".,'\1234567890'"&@CRLF& _
"|!""£$%&/()=?^.,:;-_<>"
$y = 0
$x = 0
$length = StringLen($string)+$x
$LineHeight = 90-32+$y
GUICreate("",$length,$LineHeight)
GUISetBkColor(0x000000)
GUISetState()
$string = StringUpper($string)
For $i = 1 to StringLen($string)
    If StringMid($string,$i,1)=@LF OR StringMid($string,$i,1)=@CR OR StringMid($string,$i,1)=@CRLF Then
        $x += 1
    Else
        GUICtrlCreateLabel("",$x,$y,1,Asc(StringMid($string,$i,1))-32)
        GUICtrlSetBkColor(-1,0xFFFFFF)
        $x+=1
    EndIf
Next
while 1
    If GUIGetMsg() = -3 then Exit
WEnd

supposing that what you have in the gui will go on a bitmap instead

how could I read the bitmap to get each line's length and consequantly be able to decode the string ?

basically it's just about getting each line's length (width=1px)

btw... the white parts are the ones to be read

thanks in advance

torels,

Using PixelGetColor in a series of suitable loops seems a pretty good way to get what you want.

yes I thopught of that... but I was looking for a way of doing it without having the image shown

maybe using GDI+ ... but I do'nt know how to do that XD

torels,

If you save the image in 24-bit Bitmap format, it would not be difficult to read the internal structure without having to display the image. But for a simple black/white image, that would mean an enormous size overhead - unless you compressed it yourself once it had been created......

I have done a quick search on the forums and there are some threads about searching hidden windows for pixels. Perhaps that might be something to look into?

ok thanks... I think i'll try it

anyway i've expressed myself badly... it isn't a bmp but any kind of image

thanks for your help
