While writing a simple application to monitor a poker table I was attempting to use the ImageSearch function to detect what cards had been displayed.

After many _hours_ of frustration I downloaded the source code and dug in.

Here is the problem in a nutshell: The ImageSearch function will not even LOAD an 8 bit bitmap, much less search for it.

I modified the source to allow it to load, but still no joy and I am not an advanced enought windows graphics programmer to know what to do with the GetDIBits calls, etc.

It seems that with an 8 bit bitmap, the high order bytes are going to be ignored. I know almost nothing about windows bitmap functions, so take my statements with liberal salt.

Anyhow, is there a way to fix ImageSearch so it can find an 8 bit bitmap?

Thank in advance,

I've verified that BMP files whose color depth is less than 8-bit (256 colors) are not supported by ImageSearch. Although this is by design, I've e-mailed Aurelian Maga (the developer of ImageSearch) to see if there's an easy way to support them.

In the meantime, I've documented this limitation in the help file. Thanks for reporting it.

Edit: Relu informs me that this wouldn't be that easy to support. Therefore, due to rarity of use, it will probably stay documented as a known limitation.

Edit #2: Although 8-bit color bitmaps aren't supported, 8-bit screens should work as of v1.0.40.10. If anyone has any problems with it, please let me know.
