How to bypass the Windows system palette for colorbanding (gradient colors)
Posted on 1997-05-31
In a D2 app. I present sampled data in trendcurves, using normal Delphi
routines like Canvas.MoveTo, Canvas.LineTo etc.
Now i'd like to extend the capabilities and plot the data as you sometimes
can see it in a wheather chart (all colors having gradients).
If I use the normal Delphi methods, the colors are rounded to the
NearestColor. That's not what I want since I know the video card is able to
display more precise colors.
Can anyone help me or explain it a little bit?
(Note: I already have digged into sourcecode of gradientform,
gradientcaption and gradientbutton, all found on DSP but that's not giving
the right solution).
Many thanks in advance.
