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!
With your help I have been able to conquer every problem I've faced thus far in using AutoIt, but I've come across something that I 1) don't fully understand and 2) am not sure how to even begin tackling.
I have the following list box in a GUI that I am trying to automate that I cannot read any data from. I have discussed this in a previous thread and tried several solutions, but the conclusion was that OCR would probably be the best way to go. You can see the list info and the list box(the data has been edited out) below:
I need to find a way to view the data in the list box and choose the user parameter(in this case, the correct library). There will also be instances where I will simply need to get data from another list and validate it it. I believe the major issue is that the list is populated at runtime(this was discussed in a previous thread) and that is why I cannot directly access the data in the list.
I have viewed both of these threads:
but am not able to full grasp how I should be using either of them. Unfortunately this means that I also don't really have a script to post at this point in time either. If anyone that has experience with this can help me out or point me in the right direction, that would be a huge help. This is the last piece of the puzzle for me and it has absolutely driven me crazy
I am trying to incorporate everything into AutoItx4Java, but am prepared to run an executable for these portions if necessary. Thanks in advance for any help you might be able to give! I will do my best to get back to you with any questions as soon as I can.
I have lot's of images like this
i would like to crop the page number (the arabic number on the top of the page)
so it would be something like this ...
any ideas ?
