loopz Posted July 29, 2015 Posted July 29, 2015 Hello!I need help for a small project to recover the text of an image. So I chose the Tesseract OCR .I did a lot of research on forums. I probably forgot something...For example, this code doesn't work correctly :#include <GDIPlus.au3> #include <Tesseract.au3> #include <WindowsConstants.au3> #include <TrayConstants.au3> Opt("WinTextMatchMode", -2) $img = @tempdir & "\img.png" InetGet ("http://nsa26.casimages.com/img/2011/06/24//110624070800223936.png", $img) Global $hGUI, $hImage, $hGraphic $hGUI = GuiCreate("imgtest", 145, 30, 0, 0, $WS_POPUP) GuiSetState() _GDIPlus_StartUp() $hImage = _GDIPlus_ImageLoadFromFile($img) $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI) _GDIPlus_GraphicsDrawImage($hGraphic, $hImage, 0, 0) Sleep(500) $text = _TesseractWinCapture("imgtest", "", 0, "", 1, 2, 0, 0, 5, 5, 0) GuiDelete($hGUI) MsgBox(0,"",$text) _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_ImageDispose($hImage) _GDIPlus_ShutDown() FileDelete($img) [/code]I have no errors but nothing is displayed in the MsgBox .I know that the subject has been done and redone ... So sorry, but I have the feeling of being stuck.Thanks for your help (and sorry for my english)
loopz Posted August 5, 2015 Author Posted August 5, 2015 I'm on windows 8 but i don't think it's the pb. I try everything i found, i don't understand why it doesn't work..
BrewManNH Posted August 5, 2015 Posted August 5, 2015 First off, how do you know you have no errors, you do absolutely no error checking in your script? Check @error after every function call, use consolewrite to display the value of every variable after the functions return. Then you'll know where it's failing. If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day. Teach a programmer to debug and he can do his work for a lifetime - by Chirag GudeHow to ask questions the smart way! I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Developers Jos Posted August 5, 2015 Developers Posted August 5, 2015 Thought you added some checks to ensure the performed functions were successful?Something like this right after the performed UDF or Function:ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') >Error code: ' & @error & @CRLF) ;### Debug ConsoleI see you are showing some variables now but you haven't shared whether they are correct or not.Jos SciTE4AutoIt3 Full installer Download page - Beta files Read before posting How to post scriptsource Forum etiquette Forum Rules Live for the present, Dream of the future, Learn from the past.
loopz Posted August 5, 2015 Author Posted August 5, 2015 OK thank you, i add this code : $text = _TesseractWinCapture("imgtest", "", 0, "", 1, 3, 0, 0, 5, 5, 0) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') >Error code: ' & @error & @CRLF) ;### Debug Consoleand the result in the console : @@ Debug(39) >Error code: 0
BrewManNH Posted August 5, 2015 Posted August 5, 2015 You should do something like this instead of a single error check.expandcollapse popup#include <GDIPlus.au3> #include <Tesseract.au3> #include <WindowsConstants.au3> #include <TrayConstants.au3> Opt("WinTextMatchMode", -2) ;$img = @tempdir & "\img.png" $img = "img.tif" ;InetGet ("http://nsa26.casimages.com/img/2011/06/24//110624070800223936.png", $img) ;InetGet ("img.tif", $img) Global $hGUI, $hImage, $hGraphic $hGUI = GuiCreate("imgtest", 128, 19, 0, 0, $WS_POPUP) GuiSetState() _GDIPlus_StartUp() ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') >Error code: ' & @error & @CRLF) ;### Debug Console $hImage = _GDIPlus_ImageLoadFromFile($img) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') >Error code: ' & @error & @CRLF) ;### Debug Console $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') >Error code: ' & @error & @CRLF) ;### Debug Console _GDIPlus_GraphicsDrawImage($hGraphic, $hImage, 0, 0) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') >Error code: ' & @error & @CRLF) ;### Debug Console Sleep(500) ConsoleWrite($hImage & @CRLF & $hGraphic & @CRLF) $text = _TesseractWinCapture("imgtest", "", 0, "", 1, 3, 0, 0, 5, 5, 0) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $text = ' & $text & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console ;$text = _TesseractWinCapture("imgtest", "", 0, "", 1, 2, 0, 0, 256, 38, 0) ;$text = _TesseractWinCapture("imgtest", "", 0, "", 1, 2, 0, 0, 128, 19, 0) ConsoleWrite("hello" & @CRLF) ConsoleWrite($text & @CRLF) Sleep(5000) GuiDelete($hGUI) MsgBox(0,"",$text) _GDIPlus_GraphicsDispose($hGraphic) _GDIPlus_ImageDispose($hImage) _GDIPlus_ShutDown() ;FileDelete($img)Once you see where you're getting an error, you'll start to understand where you need to fix your script.

loopz Posted August 5, 2015 Author Posted August 5, 2015 Oh i try it in the Tesseract.au3 i took and i've an error.I look at this and i tell you what it is.
LarsJ Posted August 6, 2015 Posted August 6, 2015 You don't have to reply on this. The example in first post works perfectly for me without any changes at all. Of course I have changed the half hard-coded paths for Tesseract.exe in Tesseract.au3 to the proper paths on Win 7. Controls, File Explorer, ROT objects, UI Automation, Windows Message MonitorCompiled code: Accessing AutoIt variables, DotNet.au3 UDF, Using C# and VB codeShell menus: The Context menu, The Favorites menu. Shell related: Control Panel, System Image ListsGraphics related: Rubik's Cube, OpenGL without external libraries, Navigating in an image, Non-rectangular selectionsListView controls: Colors and fonts, Multi-line header, Multi-line items, Checkboxes and icons, Incremental searchListView controls: Virtual ListViews, Editing cells, Data display functions
loopz Posted August 7, 2015 Author Posted August 7, 2015 LarsJ your answer was not necessary ... They helped me a lot, unlike you. It's the objective of this forum.BrewManNH and Jos thank you for your help, I solved my problem. For me, I've changed $tesseract_temp_path in Tesseract.au3 for the image (and not for the Tesseract.exe).Resolved
