Xylocopadream.IconTool

xd-icon makes the icons of an app from one drawing (svg or png):

Install

dotnet tool install -g Xylocopadream.IconTool

Use

xd-icon app.svg                          # app.ico, app.icns, app-256.png, app-512.png next to app.svg
xd-icon app.svg -o build/icons --ico     # only the .ico, in build/icons
xd-icon app.svg --png 48,128,256         # only these png
xd-icon app.svg --maui "#1B1E25"         # the two files of a MauiIcon, and the line for the .csproj
xd-icon --help

Small sizes drawn apart

A drawing made for 256 px blurs at 16 px. Variants for the small sizes sit next to the main image, named after it with the largest size they draw:

app.svg       48 px and more
app.40.svg    25 to 40 px (e.g. fewer details)
app.24.svg    up to 24 px (e.g. shapes on whole pixels)

The smallest variant that fits a size draws it. Variants can be png (app.16.png), a pixel-perfect image for one size.

MAUI

--maui <color> writes appicon.svg, a square of the color, and appiconfg.svg, a copy of the icon, then prints the line to put in the .csproj:

<MauiIcon Include="Resources\AppIcon\appicon.svg" ForegroundFile="Resources\AppIcon\appiconfg.svg"
          ForegroundScale="0.65" Color="#1B1E25" />

MAUI resizes them for every platform; ForegroundScale keeps the icon within the part of an Android adaptive icon that its masks (circle, squircle) never cut.
