 Posted: Sun Mar 13, 2005 6:43 am Post subject: Practical use of ASCII capture: locate a control |
 |
|
| Code: |
;
;MouseLocate by David Bradford
;
;This is an example of how to use this script
;ctrl-alt-l will position my mouse over the submit button on http://www.rottentomatoes.com
;However, to use this, you'll want to scan a control yourself. Hold down the ctrl key
;and press the left mouse button, then drag the window that appears till it covers the
;control. Be careful not to highlight or do anything that changes the appearance of the
;control, as the mouse will still do whatever it would normally do on that window.
;
;Go to Notepad and make sure you are using a fixed-width font (as a suggestion, go to
;Format->Font, select Terminal font, Regular style, and the smallest size you can). Then
;paste from the clipboard.
;
;I have switched to all alpha characters as it makes coding easier.
;
;Below, I have put the output after "scanning" the submit button from Rotten Tomatoes.
;Note that the mouse will be put in the center of whatever graphic you use, so narrow it
;down to just the control for best results.
;
;scan_x_start, scan_x_end, scan_y_start, and scan_y_end tell it what rectangle to search
;for the control.
;
;Thanks to Jon for the control selection code

Thats an interesting use for the script, though it will have problems on a system using a different font and color scheme. On the other hand it could produce matches that cannot otherwise be searched for.

For some things, yes, but the control in question here is a gif, so that won't apply in this case. For cases such as you are describing, I deal with them like this:
I have the same main .ahk script running on my home and work computers. I check upon loading the script which one I am on (through COMPUTERNAME). Then I take different paths at certain points in the script depending on which machine I am on. |

| This is pretty cool, and I love the original ascii script, but why not just use ImageSearch for this purpose? The nice thing about your method is the "image" is contained right inside the script, but that seems to be the only advantage. Then again I'm a total newbie so maybe I'm missing something subtle? |

One other thing is that my way takes less work (just highlight the image you see on the screen and you've got it). It seemed to me that when I was trying to do the same thing with ImageSearch, I had to do a printscreen, go into paint, isolate the smaller image on the screen, resize the image, etc. However, there is probably a speed disadvantage with my way (haven't really checked).
Also, I had tried ImageSearch a while back and had difficulties making it work. I think I need to give it another shot. I'd like to be able to OCR part of the screen to get the text... that would be really cool. |

After getting ImageSearch to work and seeing how fast it is, regarding my code in this post, I just want to say: nevermind!  I shall use ImageSearch from now on. |

| I just discovered ImageSearch myself and was amazed at the speed. The only thing that bugs me is it doesn't have a WindowName parameter. I'm avoiding this currently by using a Coordmode change, getting the location of the window I want to use, and then sending the search coords relative to that window, but the process would be easier if I could just tell ImageSearch which window to use. |

This sounds like a good idea: To have ImageSearch and PixelSearch optionally accept a WinTitle/WinText rather than a set of coordinates. The search could then be confined to the boundaries of that window only.
I'll add this to the to-do list. Thanks. |

Wow you really saved my life with this one
I have been trying now for 3 days to develop my own image search because ImageSearch does not work in 256 color mode.
I'm making a script that takes a random mix of units in StarCraft and sorts them into hot-key groups based on unit type.
I was hoping to be able to use your script to search for a few hundred pixels in an area 200x150 but that takes about 1 second. And I need to do it maybe 12-48 times in a second for 8 different unit icons.
Well it turns out only 10 pixels are needed for 100% accuracy in areas of high contrast so it works very fast.
Please post if you make any improvements to the program
thanks
