Original Pull Request: https://github.com/microsoft/terminal/pull/4912

State: closed
Merged: Yes

Summary of the Pull Request

Introduces convenience type til::rectangle which automatically implements our best practices for rectangle-related types and provides automatic conversions in/out of the relevant types.

PR Checklist

  • In support of Differential Rendering #778
  • I work here.
  • Tests added/passed
  • I'm a core contributor.

Detailed Description of the Pull Request / Additional comments

  • Automatically converts in from anything with a Left/Top/Right/Bottom or left/top/right/bottom (Win32 RECT)
  • Automatically converts Console type SMALL_RECT and shifts it from inclusive to exclusive on instantiation
  • Automatically converts out to SMALL_RECT (converting back to inclusive), RECT, or D2D1_RECT_F.
  • Constructs from bare integers written into source file
  • Constructs from a single til::point as a 1x1 size rectangle with top-left corner (origin) at that point
  • Constructs from a single til::size as a WxH size rectangle with top-left corner (origin) at 0,0
  • Constructs from a til::point and a til::size representing the top-left corner and the width by height.
  • Constructs from a til::point and another til::point representing the top-left corner and the exclusive bottom-right corner.
  • Default constructs to empty
  • Uses Chromium numerics for all basic math operations (+, -, *, /)
  • Provides equality tests
  • Provides operator bool to know when it's valid (has an area > 0) and empty() to know the contrary
  • Accessors for left/top/right/bottom
  • Type converting accessors (that use safe conversions and throw) for left/top/right/bottom
  • Convenience methods for finding width/height (with Chromium numerics operations) and type-converting templates (with Chromium numerics conversions).
  • Accessors for origin (top-left point) and the size/dimensions (as a til::size).
  • Intersect operation on operator & to find where two til::rectangles overlap, returned as a til::rectangle.
  • Union operation on operator | to find the total area covered by two til::rectangles, returned as a til::rectangle.
  • Subtract operation on operator - to find the area remaining after one til::rectangle is removed from another, returned as a til::some<til::rectangle, 4>.
  • TAEF/WEX Output and Comparators so they will print very nicely with VERIFY and Log macros in our testing suite.
  • Additional comparators, TAEF/WEX output, and tests written on til::some to support the Subtract operation.
  • A natvis

Validation Steps Performed

  • See automated tests of functionality.
