Subject: Re: How can I convert Tcolor to RGB?
In reply to: Carlos Ramírez 's message, "How can I convert Tcolor to RGB?" on 20:01:58 06/16/00 Fri

Hi Carlos,

By looking at the online help on TColor I found,

If you specify TColor as a specific 4-byte hexadecimal number instead of using the constants defined in the Graphics unit, the low three bytes represent RGB color
intensities for blue, green, and red, respectively. The value $00FF0000 represents full-intensity, pure blue, $0000FF00 is pure green, and $000000FF is pure red.
$00000000 is black and $00FFFFFF is white.

So using the "and" mask and the shr (shift right) operator you can extract the R,G,B values.
For example,

Blue := (Color and $00FF0000) shr 16;
Green := (Color and $0000FF00) shr 8;
Red := (Color and $000000FF);

Best regards,
