Detailed Description

Loader for .FNT files (FONT.FNT, SYSTEM.FNT, TINY.FNT, 8PNTTHIN.FNT). _LoadFont @ 1b66:023c.

Layout: u16 numChars, then per char u8 height, u8 widthBits, u8 sizeBytes, bytes[sizeBytes] bitmap.

Char → glyph table extracted from CHR2FNT (29b6:0000).

Member Function Documentation

getFontHeight()

int EEM::EEMFont::getFontHeight ( ) const

overridevirtual

Return the height of the font.

Returns

Font height in pixels.

Implements Graphics::Font.

getMaxCharWidth()

int EEM::EEMFont::getMaxCharWidth ( ) const

overridevirtual

Return the maximum width of the font.

Returns

Maximum font width in pixels.

Implements Graphics::Font.

getCharWidth()

int EEM::EEMFont::getCharWidth ( uint32  chr ) const

overridevirtual

Return the width of a specific character.

Parameters

chr	The character to query the width of.

Returns

The width of the character in pixels.

Implements Graphics::Font.

drawChar()

void EEM::EEMFont::drawChar ( Graphics::Surface *  dst, uint32  chr, int  x, int  y, uint32  color  ) const

overridevirtual

Draw a character at a specific point on the surface.

Note that the point describes the top left edge point where to draw the character. This can be different from the top left edge point of the character's bounding box. For example, TTF fonts sometimes move characters like 't' by one (or more) pixels to the left to create better visual results. To query the actual bounding box of a character, use getBoundingBox.

See also

getBoundingBox

The Font implementation should take care of not drawing outside of the specified surface.

Parameters

dst	The surface to draw on.
chr	The character to draw.
x	The x coordinate where to draw the character.
y	The y coordinate where to draw the character.
color	The color of the character.

Implements Graphics::Font.

drawWordWrapped()

int EEM::EEMFont::drawWordWrapped	(	Graphics::ManagedSurface *	dst,
		int	x,
		int	y,
		int	width,
		const Common::String &	s,
		uint32	color
	)		const

Wrap s to width via the inherited wordWrapText and draw each line at (x, y) downward. Returns total height drawn.
