RegionGetColor() function gets the average color of a portion of the screen. RegionWaitColor() function waits either until the average color of a region matches a value, or until the region's current color changes. Included are some generally useful color functions such as InvertColor() and withinVariation().
Using the AvgBitmap() func, you can get the average color of any bitmap in memory.
regionGetColor(x, y, w, h, hwnd=0)
regionGetColor_AvgBitmap(hbmp, pc)
regionGetColor_BitBlt( hdc_dest, x1, y1, w1, h1 , hdc_source, x2, y2 , mode )
regionGetColor_CreateCompatibleBitmap(hdc, w, h)
regionGetColor_CreateCompatibleDC(hdc=0)
regionGetColor_DeleteDC(hdc)
regionGetColor_DeleteObject(hbmp)
regionGetColor_GetDC(hwnd=0)
regionGetColor_invertColor(x, a = "")
regionGetColor_PrintWindow(hwnd, hdc, Flags=0)
regionGetColor_regionCompareColor(color, x, y, w, h, hwnd=0, a="", b="", c="")
regionGetColor_regionWaitColor(color, X, Y, W, H, hwnd=0, interval=100, timeout=5000, a="", b="", c="")
regionGetColor_ReleaseDC(hwnd, hdc)
regionGetColor_SelectObject(hdc, hgdiobj)
regionGetColor_SumIntBytes(bits, pc, ca, cr, cg, cb)
regionGetColor_Variation( x, y )
regionGetColor_withinVariation( x, y, a, b="", c="")
For the functions's parameters and return value, please see it's source code.
I added the prefix regionGetColor_ on all functions, except on regionGetColor() itself to make the library stdlibconform.
Infogulch is the author of this function, but borrowed some of Titans codes plus it uses MCode.
