Hello

i am trying to run image magick then get the result of the compare process 

 

#include <AutoItConstants.au3>
#include <Array.au3>

; Compare
$iPID = Run("magick compare -metric RMSE 1.jpg 2.jpg NULL:","", @SW_SHOW, $STDOUT_CHILD)

; Wait until the process has closed using the PID returned by Run.
ProcessWaitClose($iPID)

; Read the Stdout stream
$ScreenOutput = StdoutRead($iPID)

MsgBox(0,0,$ScreenOutput)

 

i have 2 questions:

1- why the console (logs) is always writing the result even that i didn't used  console write function 

2- why msg box is empty ?

Please provide more information:

  • Post the output you get when you run "magick" in a DOS window
  • @SW_SHOW isn't a valid flag  for the Run statement
  • Check for error after each function. Run sets @error
  •  Check the length of $ScreenOutput using StringLen to make sure the string is empty

Actually the strange thing that it is working but in an unexpected way !

 

it is showing the correct output in the console , but not showing in msgbox !

Modified Script: 

#include <AutoItConstants.au3>

; Compare
Global $iPID = Run("magick compare -metric RMSE 1.jpg 2.jpg NULL:", "", Default, $STDOUT_CHILD)
If $iPID = 0 Then Exit ConsoleWrite("Error running Magick! @error=" & @error & ", @extended=" & @extended & @CRLF)

; Wait until the process has closed using the PID returned by Run.
Global $iWait = ProcessWaitClose($iPID)
If $iWait = 0 Then Exit ConsoleWrite("Error returned by ProcessWaitClose! @error=" & @error & ", @extended=" & @extended & @CRLF)

; Read the Stdout stream
Global $sScreenOutput = StdoutRead($iPID)
If @error Then Exit ConsoleWrite("Error returned by StdOutRead! @error=" & @error & ", @extended=" & @extended & @CRLF)

MsgBox(0, 0, $sScreenOutput)

Replace $STDOUT_CHILD with $STDERR_MERGED to get both streams when you read Stdout.
