PkGlyph::PkGlyph	(	unsigned int	cc,
		unsigned int	tfmwidth,
		unsigned int	dm,
		unsigned int	w,
		unsigned int	h,
		int	hoff,
		int	voff,
		PkRasterdata *	rasterdata,
		PkFont *	f
	)

Represents a single glyph in a font.

The parameters here correspond to the parameters of the same names which are read from the PK file.

Parameters

cc	the character code of this glyph
tfmwidth	the width of the character, in DVI units
dm	the horizontal escapement, in pixels; this is the number of pixels rightwards (towards increasing x) that the reference should move after this glyph is set; the vertical escapement is taken to be zero
w	width of the bitmap in pixels
h	height of the bitmap in pixels
hoff	(hoff,voff) is the position of the glyph reference point, as an offset from the top-left pixel, in units of pixels, and with right and down being positive
voff	see parameter `hoff`
rasterdata	the raster information for this glyph
f	the font which this glyph belongs to

References PkFont::designSize.

PkGlyph::PkGlyph	(	unsigned int	cc,
		unsigned int	tfmwidth,
		unsigned int	dx,
		unsigned int	dy,
		unsigned int	w,
		unsigned int	h,
		int	hoff,
		int	voff,
		PkRasterdata *	rasterdata,
		PkFont *	f
	)

Represents a single glyph in a font.

The parameters here correspond to the parameters of the same names which are read from the PK file.

Parameters

cc	the character code of this glyph
tfmwidth	the width of the character, in DVI units
dx	the horizontal escapement, in pixels times 2¹⁶; this defines the number of pixels rightwards (towards increasing x) that the reference should move after this glyph is set
dy	the vertical escapement, in pixels times 2¹⁶
w	width of the bitmap in pixels
h	height of the bitmap in pixels
hoff	(hoff,voff) is the position of the glyph reference point, as an offset from the top-left pixel, in units of pixels, and with right and down being positive
voff	see parameter `hoff`
rasterdata	the raster information for this glyph
f	the font which this glyph belongs to

References PkFont::designSize.

PkGlyph::PkGlyph	(	int	resolution,
		PkFont *	f
	)

Constructs a dummy glyph for a font.

Parameters

resolution	the resolution which this glyph corresponds to
f	the font which this glyph is a member of

References PkFont::designSize.

Member Function Documentation

const Byte * PkGlyph::bitmap ( )

Returns the bitmap which represents this glyph.

This runs from the top-left of the character, with the width and height as given by methods w() and h().

Returns: the bitmap for this glyph

References PkRasterdata::bitmap().

Referenced by main().

char PkGlyph::characterChar ( ) const

inline

The character which this glyph represents.

Returns: the (ASCII) printable character which this glyph purports to represent

Referenced by main().

unsigned int PkGlyph::characterCode ( ) const

inline

The character code for this glyph.

Referenced by main().

unsigned int PkGlyph::h ( ) const

inline

Height of this character.

This is the number of columns in the bitmap returned by method bitmap()

Returns: height in device units (ie, pixels)

Referenced by main().

int PkGlyph::hEscapement ( ) const

inline

The glyph's horizontal escapement.

Returns: the escapement in pixels

int PkGlyph::hoff ( ) const

inline

Obtains the horizontal offset of the first pixel of the bitmap from the reference point for this glyph, with positive numbers indicating a rightward offset.

This is the negative of the horizontal offset of the reference point from the bitmap, as discussed in the constructor.

Returns: the offset (in pixels, with right being positive)

Referenced by main().

double PkGlyph::tfmWidth ( ) const

inline

The glyph's width.

Returns: the glyph's width in points

static verbosities PkGlyph::verbosity ( const verbosities level)

inlinestatic

Sets the verbosity of this module.

Parameters

level the required verbosity

Returns: the previous verbosity level

int PkGlyph::vEscapement ( ) const

inline

The glyph's vertical escapement.

Returns: the escapement in pixels

int PkGlyph::voff ( ) const

inline

Obtains the vertical offset of the first pixel of the bitmap from the reference point for this glyph, with positive numbers indicating a downward offset (which is rather rare, since the reference point is generally near the lower-left corner of the glyph).

This is the negative of the vertical offset of the reference point from the bitmap, as discussed in the constructor.

Returns: the offset (in pixels, with down being positive)

Referenced by main().

unsigned int PkGlyph::w ( ) const

inline

Width of this character.

This is the row-length of the bitmap returned by method bitmap()

Returns: width in device units (ie, pixels)

Referenced by main().
