Hello,
I am trying to change brightness of a color at run-time. I can get all the
components: Hue, Saturation, Brightness from Color object, and I can
obviously change these values but how can I create a new color based on
these new values?
Color oColor = Color.FromArgb( 129, 129, 129);
float fNewHue = oColor.GetHue() + 10;
float fNewSaturation = oColor.GetSatur ation() + 0.1F;
float fNewBrightness = oColor.GetBrigh tnes() + 0.1F;
// how can I build a new color based on these values?
Color oNewColor = Color.FromHSV(f NewHue, fNewSaturation, fNewBrightness) ; //
DOESN'T EXIST
Does anybody have a source for HSV to RGB (C# preferably), or is there a
work-around in .NET?
Thanks,
VR 2 19683
Steven.
Thanks a lot for your post. I found it very helpful.

As for the converting HSV/HSB format color to RGB format problem,
currently there hasn't been any buildin interfaces in the .net framework to do
this. But we can do it via our own function according to the convert algorithm. Here is a kb article discussing on the convertion (which is using C++)
#How To Converting Colors Between RGB and HLS (HBS) http://support.microsoft.com/?id=29240
Also, there is some other former threads and tech articles related to
this problem:

Hope also helps. Thanks.

Hi,
I have written a program using JAI for a project I am doing which can
be used to adjust the brightness of an image. It all works fine but I
now need to write it all up and am not entirely sure what it is doing.
The code is below:

I'm trying to implement some code in vb.net to allow the user to
adjust the brightness or contrast on an image (through the use of a
slider) that is already black & white in the bitmap. I have tried
to use the colormatrix and even down to the pixel using GetPixel and
SetPixel in system.drawing, but I'm really not up on using gdi+ and
haven't really gotten anywhere. I've seen some examples for VB6, but
I need vb.net.

Hi,
I have two bitmaps that look the same, except in color. Is there a
simple way to "subtract" the color of one bitmap, pixel by pixel so
that only the difference in colour remains. For instance, if I take a
pixel at point (50,75), and find that the colours are FF00FF and FF0000
respectively, is there a way to determine that the residual colour is
0000FF ?
Thanks in advance!

Hello!
I'm using Bitmap->LockBits method to copy its pixels into an array
according to example found on
http://msdn2.microsoft.com/en-us/library/5ey6h79d.aspx . Now I need to
use pixels' brightness. How do I get such info? I guess that requires
some special PixelFormat argument.
Thanks in in advance for all hints.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
