PgGlyphString

A PangoGlyphString is used to store strings of glyphs with geometry and visual attribute information.

The storage for the glyph information is owned by the structure which simplifies memory management.

class PgGlyphString {

PangoGlyphString* pangoGlyphString;

bool ownedRef;

PangoGlyphString* getPgGlyphStringStruct(bool transferOwnership);

void* getStruct();

this(PangoGlyphString* pangoGlyphString, bool ownedRef);

static GType getType();

PgGlyphString copy();

void extents(PgFont font, PangoRectangle inkRect, PangoRectangle logicalRect);

void extentsRange(int start, int end, PgFont font, PangoRectangle inkRect, PangoRectangle logicalRect);

void getLogicalWidths(string text, int length, int embeddingLevel, int[] logicalWidths);

int getWidth();

void indexToX(string text, int length, PangoAnalysis* analysis, int index, bool trailing, int xPos);

void setSize(int newLen);

void xToIndex(string text, int length, PangoAnalysis* analysis, int xPos, int index, int trailing);

}

Constructors

this this(PangoGlyphString* pangoGlyphString, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Create a new PangoGlyphString.

Destructor

Functions

copy PgGlyphString copy(): Copy a glyph string and associated storage.
extents void extents(PgFont font, PangoRectangle inkRect, PangoRectangle logicalRect): Compute the logical and ink extents of a glyph string.
extentsRange void extentsRange(int start, int end, PgFont font, PangoRectangle inkRect, PangoRectangle logicalRect): Computes the extents of a sub-portion of a glyph string.
free void free(): Free a glyph string and associated storage.
getLogicalWidths void getLogicalWidths(string text, int length, int embeddingLevel, int[] logicalWidths): Given a PangoGlyphString and corresponding text, determine the width corresponding to each character.
getPgGlyphStringStruct PangoGlyphString* getPgGlyphStringStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getWidth int getWidth(): Computes the logical width of the glyph string.
indexToX void indexToX(string text, int length, PangoAnalysis* analysis, int index, bool trailing, int xPos): Converts from character position to x position.
setSize void setSize(int newLen): Resize a glyph string to the given length.
xToIndex void xToIndex(string text, int length, PangoAnalysis* analysis, int xPos, int index, int trailing): Convert from x offset to character position.
