OCR from html page? Reading/ interpreting/

5 posts in this topic

I've got a scheduling program that I use (written in Autoit) which is now being required to enter a "control code" to complete the process. I'm at a loss as to where to go from here. Please help, I'll do the needed research, just need to know the best way to advance. What I need to do is read the 6 images from the webpage, then interpret them to their appropriate number. Later on in the script I'll insert them into the input box and submit (already have that process).

Here is what that section of the html code looks like.

<B CLASS=alert>

Please enter the control code shown below to submit your request.</B>

<BR>

<TABLE><TR><TD>

</TD></TR><TR><TD>

Enter Control Code </TD>

In this case, the images are output the number 299073. The website is blocking me from rt clicking and saving any images (which I'm sure I can get around but appreciate the advice if any out there). I'm pretty sure that each digit looks the same, but are simply being rearranged. Attached is an exaple pic of what the webpage looks like

Thanks for any help.

maybe its possible to scan all the gifs and see with crc check which are equal? then reduce to the numbers 0-9 :: bots/000001.gif --> bots/999999.gif etc...

junkew,

Thanks for the fast reply. I'll get busy on reading up on this code it... is a little over my head as yet. You've obviously done some awesome work here.

Since I can't right click on this web page, what is the best way to screen shot that area of the screen to find the bitmaps first, then later while running the script? I'm guessing the best option is the "_screencapture" seris of commands

Thaks again, already a huge help.

After doing more research on _screencapture, it seems the limitation is on finding the xy coordinates.....

In my page, the needed coordinates are right before the submit buttons at the bottom, unfortunately, the size of the page is always changing based on the information retrieved.

I'm guessing that I should find the xy cordinates of the submit button, then work backwards towards the capture area? Anybody tried that?
