Member Function Documentation

getFontHeight()

virtual int CryOmni3D::CryoFont::getFontHeight ( ) const

inlinevirtual

Return the height of the font.

Returns

Font height in pixels.

Implements Graphics::Font.

getMaxCharWidth()

virtual int CryOmni3D::CryoFont::getMaxCharWidth ( ) const

inlinevirtual

Return the maximum width of the font.

Returns

Maximum font width in pixels.

Implements Graphics::Font.

getCharWidth()

virtual int CryOmni3D::CryoFont::getCharWidth ( uint32  chr ) const

virtual

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.

getBoundingBox()

virtual Common::Rect CryOmni3D::CryoFont::getBoundingBox ( uint32  chr ) const

virtual

Calculate the bounding box of a character.

It is assumed that the character shall be drawn at position (0, 0).

The idea here is that the character might be drawn outside the rect (0, 0) to (getCharWidth(chr), getFontHeight()) for some fonts. This is common among TTF fonts.

The default implementation simply returns the rect with a width of getCharWidth(chr) and height of getFontHeight().

Parameters

chr	The character to draw.

Returns

The bounding box of the drawn glyph.

Reimplemented from Graphics::Font.

drawChar()

virtual void CryOmni3D::CryoFont::drawChar ( Graphics::Surface *  dst, uint32  chr, int  x, int  y, uint32  color  ) const

virtual

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.
