Interface Scaler

All Known Implementing Classes:

CFFScaler, TTScaler, Type1Scaler

public interface Scaler

A scaler provides access to font data dependent on a size and target device. The method setDebugger(com.adobe.fontengine.font.ScalerDebugger) can be called at any time. The calls to the other methods must follow the pattern (setScale (getOutline | getBitmap)* )*.

Method Summary

Modifier and Type	Method	Description
void	getBitmap(int gid, BitmapConsumer bitmapConsumer)	Return the bitmap of a glyph.
void	getOutline(int gid, OutlineConsumer outlineConsumer)	Return the (hinted) outline of a glyph.
void	setDebugger(ScalerDebugger outlineDebugger)	Set a debugger to receive details about the computations.
void	setScale(double pointSize, double ppemX, double ppemY, double dX, double dY)	Set the scale factor for the font, and describe the target device.

Method Detail

setScale

void setScale(double pointSize,
              double ppemX,
              double ppemY,
              double dX,
              double dY)
       throws InvalidFontException,
              UnsupportedFontException

Set the scale factor for the font, and describe the target device.

Throws:

InvalidFontException

UnsupportedFontException

getOutline

void getOutline(int gid,
                OutlineConsumer outlineConsumer)
         throws UnsupportedFontException,
                InvalidFontException

Return the (hinted) outline of a glyph. Hinting that may be provided by the font is applied. The coordinates are in device space.

Throws:

UnsupportedFontException

InvalidFontException

getBitmap

void getBitmap(int gid,
               BitmapConsumer bitmapConsumer)
        throws UnsupportedFontException,
               InvalidFontException

Return the bitmap of a glyph. Hinting that may be provided by the font is applied. The coordinates are in device space.

Throws:

UnsupportedFontException

InvalidFontException

setDebugger

void setDebugger(ScalerDebugger outlineDebugger)

Set a debugger to receive details about the computations. This is used for development purposes only.
