Happy New Year everyone!
I would like to extract the color values of certain pixels in an image. This is how I picture the workflow:
User opens an image of his choice. Image is shown on the screen. User draws a line into the image. This happens by marking the startpixel and the endpixel of the line The line is drawn, so the user can check visually if he is happy with the line. The following pixel based properties belonging to the line are stored in Excel: X-Coordinate Y-Coordinate Color Value Additional operations: Extracting for max- and min. color values; Statistical operations. Browsing through the helpfile of AutoIt I find plenty of functions for treating images (e.g. GDIPlus), but I am completely unsure if Autoit will get me there. Should I read the entire image into an array? Should I rather attempt to script an external image software (e.g. IrfanView, Gimp)?
I would be very thankful if someone could give some recommendations and maybe list a couple of the most important commands to use.
Thank you very much.
Currently, I'm using Opencv UDF and i'm encountering issues with DLLOPEN(). it is failing and returning -1
But, I cannot figure out why it is failing.
I need help from people.
I'm running windows 10 32bit.
This's my code.
#RequireAdmin $fileopen = DllOpen("opencv_core2413.dll") MsgBox(0,"Result",$fileopen) Example.au3opencv_core2413.dll
This script used to work on an older version of AutoIT. Currently I am running AutoIT v126.96.36.199 and it's failing.
Func PublicIP() ;Post public facing IP address Local $url = 'https://www.google.com/search?client=opera&q=what+is+my+ip&sourceid=opera&ie=UTF-8&oe=UTF-8' Local $getIPaddress = BinaryToString(InetRead($url)) Local $sStart = 'clamp:2">' Local $sEnd = '</div>' Local $ipaddress = _StringBetween($getIPaddress, $sStart, $sEnd For $i In $ipaddress MsgBox(0, 'External IP', "Your public IP address is " & $i) Next EndFunc ;==>PublicIP The console output shows:
"C:\Users\user\Documents\AutoIT\Scripts\WSI Tools.au3" (197) : ==> Variable must be of type "Object".: For $i In $ipaddress For $i In $ipaddress^ ERROR ->14:12:16 AutoIt3.exe ended.rc:1 +>14:12:16 AutoIt3Wrapper Finished. >Exit code: 1 Time: 9.811
I'm listing the error message strings, and roughly matching the error code
Is this how to do error reporting? Is there a more simple way I don't know about?
I realise I might not need to trap @error inside $error. I like it this way b/c I have no fear of overwriting @error now; I don't even use it.
Func Send_Connect($address, $port) $socket = TCPConnect($address, $port) $error = @error If $error <> 0 Then Local $aError = ["-2 not connected.", _ "1 IPAddr is incorrect.", _ "2 port is incorrect."] $aError = "10060 Connection timed out." If $error < 0 Then $error = 0 If $error > 2 Then $error = 3 MsgBox(0, "TCP Connect Error", $aError[$error], 0) $socket = 0 EndIf Return $socket EndFunc
I am wondering if is there any autoit function that make the program ignore errors and move on and resume correct lines?
