pub struct LogicalSize {
pub width: f64,
pub height: f64,
}
Expand description
A size represented in logical pixels.
The size is stored as floats, so please be careful. Casting floats to integers truncates the fractional part,
which can cause noticable issues. To help with that, an Into<(u32, u32)>
implementation is provided which
does the rounding for you.
