I have a one dimensional byte array that stores the pixel information
of my image. The image is 8-bit grayscale so each byte in the array
holds a value from 0(black) to 255(white) for a single pixel. I need
a way to save this this byte array as a gif. Does anyone have any
suggestions???

I'm using bmp.Save() and the bmp is in PixelFormat.Format8bppIndexed.
But when I open the image with Gimp, it tells me that the image is RGB
and not grayscale.

Hello
I translated this code (witch convert an image to grayscale) from C#.NET to
C++.NET
The C#.NET code is :
private void GrayScale(Bitmap b)
{
BitmapData bmData = b.LockBits(new Rectangle(0, 0, b.Width,
b.Height),ImageLockMode.ReadWrite,PixelFormat.Format24bppRgb);
int stride = bmData.Stride;

I'm having trouble reducing the size of a bitmap programmatically: The file
size of the original is 2400k.
The picture is 816x1056. 16 million colors i think. I only need grayscale
render.
Public Sub ConvertBadBitmap(ByVal FilePath As String)
Dim objPicture As New Bitmap(816, 1056,
System.Drawing.Imaging.PixelFormat.Format16bppGrayScale)
objPicture = objPicture.FromFile(FilePath)
objPicture.Save("C:\ConvertPHOTO.bmp")

Hi I was at the search for making e.Graphics.DrawImage turn any image
to Grayscale, and I found two similar solutions but different
ColorMatrix values, what is the difference between the two? Is there
an industry standard for the GrayScale ColorMatrix values?
Thanks,

Currently I got a thermal image mapping program which converts grayscale pictures to RGB. Now, what I need to do is to convert those 3 RGB colors into other three colours. The choice of colours are white, black, red, green and blue.
To explain more, for the thermal mapping using grayscale converted to RGB, red denotes hot areas, green-zero, and blue-cold. What I want to do is to make a program that enables you to choose the colours from the...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
