Hi!
I am developing an application in ASP.NET that takes an image, that have
been created with a digital camera or camera phone, and processes it, to
get data from it. The image taken by the user will be of a square in some
kind of magazine or newpaper, with a white background and the border of the
square should be black.

in the image, using ASP.NET code. If the...

Let's say I have an image which is monochrome with areas of white, black and
shades of gray. Now I want to turn all the white parts into some RGB color
but it also needs to be darkened by the gray areas for the same color.
Like say it's an image of a sphere, it is white in the part it is under the
light but then as you get away from the light source it becomes darker and
darker gray. Now I want to take this image and apply just one RGB...

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

For most users, this new feature is actually very convenient. If you want to control the update process,...
