row_pixel_dims()

MAYAFLUX_API glm::uvec2 MayaFlux::Portal::Forma::row_pixel_dims	(	const std::shared_ptr< Core::Window > &	window,
		float	x_min,
		float	x_max,
		float	row_h
	)

Convert an NDC row rect into integer pixel dimensions.

Clamps width to at least 1 pixel and height to at least the default atlas pixel size to avoid degenerate textures.

Parameters

window	Target window for pixel dimension calculation.
x_min	Left edge in NDC.
x_max	Right edge in NDC.
row_h	Row height in NDC units.
