◆ recalculateFontSizes()

void gui::renderer::FontManager::recalculateFontSizes	(	float	aspectX,
		float	aspectY,
		float	xScale,
		float	yScale
	)

static

Recalculates the font sizes.

This method adapts the font sizes by multiplying them by the a scale factor.

The scale factor is calculated according to the following formula:

scaling = min(aspectX, aspectY) * min(xScale, yScale)

Parameters

aspectX	The aspect ratio of the window width to the base width (constants::FONT_ASPECT_BASE_WINDOW_WIDTH)
aspectY	The aspect ratio of the window height to the base height (constants::FONT_ASPECT_BASE_WINDOW_HEIGHT)
xScale	The scale factor for the X axis
yScale	The scale factor for the Y axis
