Constructor & Destructor Documentation

◆ LcdGlyph()

Graphics::LcdGlyph::LcdGlyph	(	size_t	bmOffset,
		const Options &	options
	)

Member Function Documentation

◆ getBits()

Bits Graphics::LcdGlyph::getBits ( uint16_t row ) const

inlineoverridevirtual

Implements Graphics::GlyphObject.

◆ init()

bool Graphics::LcdGlyph::init ( )

inlineoverridevirtual

Initialise the object, e.g. parse header content and obtain dimensions.

Implements Graphics::ImageObject.

◆ readAlpha()

void Graphics::LcdGlyph::readAlpha	(	void *	buffer,
		Point	origin,
		size_t	stride
	)		const

overridevirtual

Obtain glyph information as block of 8-bit alpha values.

Parameters

buffer
origin	Location of cursor within buffer
stride	Number of bytes per row in buffer

This method is called with a positive origin to accommodate negative x/y glyph offsets. Italic and script typefaces do this a lot!

Implements Graphics::GlyphObject.
