ScaledFont

this this(cairo_scaled_font_t* ptr): Create a ScaledFont from a existing cairo_scaled_font_t*. ScaledFont is a garbage collected class. It will call cairo_scaled_font_destroy when it gets collected by the GC or when dispose() is called.
this this(FontFace font_face, Matrix font_matrix, Matrix ctm, FontOptions options): Creates a ScaledFont object from a font face and matrices that describe the size of the font and the environment in which it will be used.

Functions

checkError void checkError(): Method for use in subclasses. Calls cairo_scaled_font_status(nativePointer) and throws an exception if the status isn't CAIRO_STATUS_SUCCESS
extents FontExtents extents(): Gets the metrics for a ScaledFont.
getCTM Matrix getCTM(): Returns the CTM with which ScaledFont was created. Note that the translation offsets (x0, y0) of the CTM are ignored by new ScaledFont(). So, the matrix this function returns always has 0,0 as x0,y0.
getFontFace FontFace getFontFace(): Gets the font face that this scaled font uses. This is the font face passed to new ScaledFont().
getFontMatrix Matrix getFontMatrix(): Returns the font matrix with which ScaledFont was created.
getFontOptions FontOptions getFontOptions(): Returns the font options with which ScaledFont was created.
getScaleMatrix Matrix getScaleMatrix(): Returns the scale matrix of ScaledFont. The scale matrix is product of the font matrix and the ctm associated with the scaled font, and hence is the matrix mapping from font space to device space.
getType FontType getType(): This function returns the C type of a ScaledFont. See FontType for available types.
glyphExtents TextExtents glyphExtents(Glyph[] glyphs): Gets the extents for an array of glyphs. The extents describe a user-space rectangle that encloses the "inked" portion of the glyphs, (as they would be drawn by Context.showGlyphs() if the cairo graphics state were set to the same fontFace, fontMatrix, ctm, and fontOptions as scaled_font). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by Context.showGlyphs().
textExtents TextExtents textExtents(string text): Gets the extents for a string of text. The extents describe a user-space rectangle that encloses the "inked" portion of the text drawn at the origin (0,0) (as it would be drawn by Context.showText() if the cairo graphics state were set to the same fontFace, fontMatrix, ctm, and fontOptions as ScaledFont). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by Context.showText().
textToGlyphs Glyph[] textToGlyphs(double x, double y, string text, Glyph[] glyphBuffer)
Glyph[] textToGlyphs(Point!double p1, string text, Glyph[] glyphBuffer)
textToTextGlyph TextGlyph textToTextGlyph(double x, double y, string text, Glyph[] glyphBuffer, TextCluster[] clusterBuffer)
TextGlyph textToTextGlyph(Point!double p1, string text, Glyph[] glyphBuffer, TextCluster[] clusterBuffer): Converts UTF-8 text to an array of glyphs, optionally with cluster mapping, that can be used to render later using ScaledFont.
