Picture recognition

[Marcus Tettmar]

If I have understood you correctly you have several predefined images on disk and you want the macro to tell you which one of those is on the screen at a specific place. You can use the CompareBitmaps example. The only difference is that you will run it in a loop for each of the images on disk, and instead of taking the whole screen you will extract the portion of the screen which you want to compare against each image on disk. Alternatively use FindImgPos for each image against a dump of the entire screen and see which one returns as found.

Here is a sample of code which will take a screen shot of the current app, then search within that window for a specific bitmap file. this may be a good starting point for you. Try this, then we can discuss how to make it more complex.

Of course, you will need to edit the paths/files as yours are likely to differ.
