I use a bitmap class new bitmap(filepath)
this should and does load my jpg into memory.
I then want to use mybitmap.save(filepath,imaging.imageformat.jpeg) to save
it; overwriting the original.
If this outfile path is different there is no problem but when it is the
same file it blows up with a generic GDI+error.

I'm a VB.NET newbie. I've created a program that plots pixels at random on
the form. I have a 19" LCD monitor with a resolution set to 1280 by 1024. If
you do the math, that means that there are over 1.3 million pixels. In one
version of the program, the pixels start plotting at the upper-left & go down
the form from top to bottom & left to right. In another version, the pixels
are plotted at random. I have a 2.4 GHZ Athlon 64 with 1...

Hello!
My goal is to develop a program that opens a bitmap, copies its pixels
to an ArrayList in order to perform some complex calculations (edge
detection, Hough transform etc.), and save resulting image back in some
other bitmap.
It works pretty fast, except for stages of coping pixels between bitmap
(object of type Bitmap) and the ArrayList. I'm using the trivial

I've been looking on the Internet for a way to convert a DIB to a Bitmap
without success.
Now I'm wondering if that is the approach I should be taking.
All I want to do is display the DIB or draw it into a Bitmap.
Is there a graphics method that can help?

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...

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....
