      MapIt is a tile world editor.  MapIt was built around the concept of reversing Dragon Warrior map images.  MapIt can take image input and produce a tile and world array.  
      Changing and replacing tile / world data is easy.  B/c tile world editor.

      CTRL+R in image above to signal replace tile action and I use "G" to Get the tile under mouse.
      A full list of hotkeys can be assigned in the: Help Menu\Hotkeys
       
      MapParser is a C++ project that scans images for unique tiles. 
      MapIt can be downloaded without MapParser. MapParser can be toggled off in the Scan_Image dialog. Without MapParser, MapIt will use the Scan_Tiles() function written in AutoIt ; which is 100 * slower Idk. If MapParser.exe will not run for you:      Installing Visual C++ Redistributable for Visual Studio 2015 should fix it: https://www.microsoft.com/en-us/download/details.aspx?id=48145   
      You can start with example world and tiles.
      Example world was made following these steps:
      Started with a tile map image of DragonWarrior3 town of: Reeve From MapIt World Menu \ New \ Scan_Image dialog, I set the area to exclude the key legend to the far right of image. After scanning the map image to world and tile array.  I removed a few of the map artifacts.  More work could be done on this world; removing unwanted tiles, but it is fine for now. I saved my world to disk.  This creates folder: Worldname: Containing folder of Tiles and a Worldname.txt. Using The Gimp, I edited some tiles to have a transparent color: Stairs, Trees, Desk Tables, Chest-of-drawers, Chairs, Signs, Doors, Beds. I changed the world layers to 2: World Menu \ Properties. F9 Finds all selected tile on current layer and changes to a new selected tile on new layer. I used F9 to change all Trees on layer: 0 to Trees on layer: 1. Then I used F9 to change all Trees on layer: 0 to Grass on layer: 0  
      In this video you can see how I used the Tile Menu \ Replace From Disk option to remap tile images to my custom tiles.  Conveniently my tiles already have a transparent pixel.
      See video for how that was done:
      To use the example world:
      First unzip the world save file: http://songersoft.com/programming/mapit/worlds/Reeve_Swapped.zip From the World Menu: choose \Load Navigate to the Reeve_Swapped.txt located in the extracted zip. Or you can scan any image.
      The map images I used are here: http://www.realmofdarkness.net/dq/games/nes/dw3/maps/world
      For download, videos, and example of created world file data; please visit the MapIt webpage: http://songersoft.com/programming/mapit/mapit_about.phtml

      Trying to ocr some values on chart in real time(once per minute) and buy/sell securities on basis of alert generated in my software.
      I am struck onto few steps.
      1. On Tesseract Screen Capture indentation parameters. How can we determine the exact parameters if I just want numeric values only.
      2. The Tesseract Screen Capture generates and error Obj1 on line 185 which needs to be resolved.
      3. Sometimes lines get overlapped with values. What to do in that case.
      3. Detecting the sound as and when it approaches and then comparing the ocr values to decide on either buy or sell.
      The values that needs to be fetched are encircled.

      I have a situation where I am repeatedly capturing a region of the screen and feeding it into Tesseract OCR.  Since the OCR is a relatively slow operation, I would like to create an in memory cache of the ocr results.  An ideal hash key for this cache would be a checksum of the captured image.  With this I could capture the region, checksum it, and then only if I don't get a cache hit I would write the image out to disk for external OCR.
      Now I know I can do this by saving the captured image out to disk, and then summing the disk file with _Crypt_HashFile().  But that's still slower than I would like, and it shouldn't be necessary.  Ideally, it should be possible to checksum the image data directly in memory so I don't have to go to disk at all.  In order to do that, I need a way to dump a representation of the image into a string  (or some equivalent).  Then I could use the _Crypt_HashData() function against that string to create my cache hash key.
      Googling around I found an article here that shows a way to convert an image object to a byte array using System.Drawing.  This was the closest thing I found to what I'm trying to do.  I don't know if that method could be used from within AutoIT, or if perhaps there may be a better way I don't know about.  If someone could give me a shove in the right direction it would be a big help.  Thanks!

      Howdy, I've gone through a lot of au3 forums, and I once had a working Imagesearch script that I got from here.  However, and i'm just totally not sure how but my imagesearch scripts aren't working anymore.
      I'm not new to au3 but i'm not the most experienced with it's syntax/commands.

      Anyways, I've looked over the big threads involving imagesearch.

      Does anyone have a working Imagesearch x64 for win10 that is currently working as of the date with the post.

      Dll's and what not is fine, just when I tell the script to run, I want to be able to find the image on the screen!
      Can't find a working copy so if anyone has one please send it my way lol.

      I've taken all the imagesearch downloads and what not and have played with them but I can't get any of them working on my end, despite others saying they're working.
      Thanks.
