Introduction

This is a collection of utility functions I found I often need in my projects. They are split over 3 packages:

• PowBasics General utility functions (no dependencies)
• PowBasics.Geom Structs & utils for Rectangles, points, margins... (no dependencies)
• PowBasics.WinForms Utilities for WinForms depends on WinForms
• PowBasics.Rx Utilities for reactive extensions depends on System.Reactive

PowBasics

Math

public static class MathUtils
{
    // Cap a number between 2 bounds (inclusive)
    int Cap(int val, int min, int max);

    /*
      Compute the minimum number of multiples of b we need to be at least a
      Note: this is not the same as integer division.
      Integer division: 7 / 3 = 2 (but 2*3=6 doesn't cover/fill 7 completely)
      FillingDiv(7, 3) = 3
    */
    int FillingDiv(int a, int b);
}

PowBasics.Geom

It contains :

• records for points, size, rectangles (both with int & double coordinates)
• records for margins and padding

It has all the operations you'd expect either as member methods or extension methods. Including:

• + & - operators between rectangles (R) and margins & paddings (Marg && Pad)
• Mirror operations for margins & paddings. (Swaps x and y coordinates)

record Pt(int X, int Y);
record R(int X, int Y, int Width, int Height);
record Sz(int Width, int Height);

record VecPt(double X, double Y);
record VecR(VecPt Min, VecPt Max);

enum Dir { Horiz, Vert }

interface IMarg {
    int Top { get; }
    int Right { get; }
    int Bottom { get; }
    int Left { get; }
}

record Marg(int Top, int Right, int Bottom, int Left) : IMarg;
record Pad(int Top, int Right, int Bottom, int Left, int InBetween) : IMarg;
