Scale Factor for Microcontrollers

When targeting a Microcontroller, there exists no windowing system that provides a device pixel ratio to map logical lengths in Slint (px) to physical pixels (phx). If desired, you can provide this ratio at compile time by setting the SLINT_SCALE_FACTOR target property on your CMake target.

# Example: when building my_application, specify that the scale factor shall be 2
set_property(TARGET my_application PROPERTY SLINT_SCALE_FACTOR 2.0)

cmake

A scale factor specified this way will also be used to pre-scale images and glyphs when used in combination with Resource Embedding.
