Individual RGB values from TColor....

[onrdbandit]

Howdy,

I want to use a TColorDialog to allow the user to select a color, but the value returned is as of TColor type. I need to extract the individual values (red, green, and blue) from the TColor type.

If someone could explain how to seperate the values from the single value returned by ColorToRGB(TColor Color); that would solve my problem.

I cant seem to find any valid info on this topic. I have found some info saying the TColor type has member functions, but it does not seem to have a class stucture.

Thanks for any assitance...

Search the documentation, because there is some functions that return each color : Red, Green, Blue.
Or you can apply some bit operation(binary and and shift to right) on the TColor variable to find each color.
TColor in hexa is something like this : 0xRRGGBB.

You can use global windows defines:
GetRValue(DWORD rgb);
GetBValue(DWORD rgb);
GetGValue(DWORD rgb);

Thanks,

I found those functions, and they work great. I spent so long looking for answers without finding anything, that I wanted to make sure I was not searching in vain...

Thanks anyways,
