Constructor Detail

TextureTextRenderer

public TextureTextRenderer(int preferredWidth,
                           int preferredHeight,
                           int maxDimension)

TextureTextRenderer

public TextureTextRenderer(int preferredWidth,
                           int preferredHeight,
                           int maxDimension,
                           boolean antialiasing)

Method Detail

getImageStore

public TextImageStore getImageStore()

Returns:

Image store with packed glyphs

getWidth

public int getWidth()

Returns:

width of the backing image store

getHeight

public int getHeight()

Returns:

height of the backing image store

setAntialiasing

public void setAntialiasing(boolean set)

Enable or disable antialiasing in the backing image store

isAntialiasing

public boolean isAntialiasing()

Whether or not antialiasing is enabled

setFont

public void setFont(java.awt.Font font)

Default font to use for methods in which the font is not specified

Parameters:

font - default font

getFont

public java.awt.Font getFont()

Returns:

the default font

begin

public void begin()

Prepare a queue for optimized rendering of characters

drawText

public float drawText(java.awt.Font font,
                      java.lang.String text,
                      float[] loc,
                      float emsize)

Renders text with a given font at a provided baseline location.

Specified by:

drawText in interface TextRenderer

Parameters:

font - font to use. Note that the font's size controls the resolution of the glyphs in the backing texture. The final drawn font size can be controlled using emsize. Rendering might not take place immediately. This class creates a queue to minimize the number of required changes to a backing texture. To force a render, use flush().

text - text to draw

loc - baseline location to start drawing

emsize - size of an 'em' unit

Returns:

the advance distance in the x-direction (width of text)

flush

public void flush()

Draw characters to screen now

end

public void end()

getTextBounds

public java.awt.geom.Rectangle2D getTextBounds(java.awt.Font font,
                                               java.lang.String text,
                                               float size)

Description copied from interface: TextRenderer

Bounding rectangle. Includes ascent, descent, leading, advance. Some glyphs may extend beyond these bounds in some fonts. Bounds are base-line relative, with the position being the bottom-left corner.

Specified by:

getTextBounds in interface TextRenderer

Parameters:

font - font used for sizing

text - text to bound

size - 'em' unit size

Returns:

bounding rectangle

setPreferredSize

public void setPreferredSize(int width,
                             int height)
