About
What's this?
This library contains some utility functions I have been developing over the last decade or so (some even longer) and that I use extensively in almost anything I write/maintain these days.
What's so special about that?
There might not be anything really special about this, but maybe you think some of this is useful in your daily .NET developing life? These include things like:
- Manipulation of and near-equality checks on
Colorinstances through some extension methods. - Some basic creation and edit methods on
Bitmapimage instances.
Who created this?
My name is Jarno Peschier. I started programming on a Commodore 64 in high school, got a masters degree in Computer Science at Utrecht University at the end of the last century, specializing in GIS algorithms, and I have been developing software all my professional life.
You might also know me by my online name of peSHIr, which is basically the way you write my last name phonetically in Klingon.
At the start of 2025 I worked as a software engineer at Dutch engineering firm Iv, where I personally handled all software development around our scan vehicle (YouTube) using multiple third party software packages, C#, and PowerShell.
The laserscan and photo data Iv collects using this vehicle is used in infrastructure projects all over the Netherlands, but also for monitoring things like trees or quay walls in Amsterdam.
