PNG Image Format

PNG [http://www.libpng.org/pub/png/] is an image format commonly used where lossless encoding with alpha information is required. It does have some issue with inconsistent gamma correction [https://hsivonen.fi/png-gamma/] in some context but is never the less a popular format to support. License and Source

If you access your Windows drives from Linux, it is very slow under WSL2. This thread [https://github.com/microsoft/WSL/issues/4197] reporting the issue is more than a year old. If you are like me and value the convenience of being able to access Windows files from Linux,

ANSI Colors in Command Prompt

{fmt} has this nice feature allowing you to use colors [https://github.com/fmtlib/fmt] for your output via ANSI escape code [https://en.wikipedia.org/wiki/ANSI_escape_code]. Too bad when I tried to run it under Windows the first time all I saw was the escape code

Debugging DLL, CMake, and Visual Studio 2019

Date/Time Manipulations

C++ provides std::chrono::system_clock::time_point that represents time, that works well with other classes such as durations (std::chrono::milliseconds, etc.). However, it isn't always sufficient for date time manipulations because of daylight savings and leap years. Since time_point represents time interval since the
