I am saving a BufferedImage as a JPEG file under Windows XP.
I am using the JAI JPEGImageEncoder class.
The JPEG is saved as CMYK but I need RGB.
I cannot figure out how to get RGB. Any help?

Hi,
I am using Tkinter and I have a Label and a Scale. I want to update
my label everytime the Scale value changes. What is the best way of
doing this? Do i have to bind for every event type? Or is there some
better way? If I do have to bind each type of event to the scale, what
types occur for a Scale?
Thanks.

A very useful feature was added in 2.0 of .NET framework which was the
scaling of a form and all the controls within it. This is really useful but
I am finding very little information of how to use it.
I have managed to implement it as follows:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim addSize As New SizeF(0.5F, 0.5F)

Hello!
We have a pc running a form application.
If I push some buttons in this application I want to send some commands to a
scale which is connected
to a specific IP address. When I sent a command I also receive an answer
from the scale.
I want to communicate with the scale using TCP or UDP.
The commands that can be sent to the scale are very short about 3 to 5
characters.

I want to get the R, G and B components as integers (0-255). I use this:
Rectangle area = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
BufferedImage bufferedImage = r.createScreenCapture(area);
int pixel = bufferedImage.getRGB(x,y);
But it returns some crazy 1 value of -65536 or something like that. How do I convert it to three individual integers R,G and B?

I'm trying to save a BufferedImage as a .tiff.
The following:
ImageIO.write(bufferedImg, "TIFF", new File("file.tiff"));
is returning false.
Do I need to use JAI?
I'm just trying to use the easiest way to save a .tiff.
Thanks.

I have a whiteboard I'm working on at the moment but I have no idea how i should transport the user's input on the canvas to the recipient. Someone suggested using BufferedImage.
Can anyone please explain to me what Serialization and BufferedImage are, what they do, and how they work?? And how I should implement them in a whiteboard??

Hi!
I've to scale a vector of numbers of size N to a vector of size M.
The trasformation is like a zoom on images but I need on a vector.
The second size can be M >= N or M <= N, M 0.
The value for each element can be from 0 to 255.
Is there some methods that can I use?

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
