I have a project, and would like to support screen brightness up/down in C#,
anyone can help me about this issue, I know one possibility is write a
driver, and
AP through driver to control the H/W.
Is anyway can adjust the screen brightness without driver? 2 6976
Steve,
If the display supports it, you can call the DeviceIoControl function
through the P/Invoke layer in the Windows API, and pass
IOCTL_VIDEO_SET _DISPLAY_BRIGHT NESS for the dwControlCode parameter.
Hope this helps.

Nicholas,
thanks for the hint, yes, it should be the easiest way to adjust the
brightness, really appreciated.

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:
public void adjustLight(int ipParam){ // ipParam = 18
pb = new ParameterBlock();

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;

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.
