Enclosing class:

Font

public static class Font.GlyphRegion
extends com.badlogic.gdx.graphics.g2d.TextureRegion

Describes the region of a glyph in a larger TextureRegion, carrying a little more info about the offsets that apply to where the glyph is rendered.

Field Summary

Fields

Modifier and Type	Field and Description
float	offsetX The offset from the left of the original image to the left of the packed image, after whitespace was removed for packing.
float	offsetY The offset from the bottom of the original image to the bottom of the packed image, after whitespace was removed for packing.
float	xAdvance How far to move the "cursor" to the right after drawing this GlyphRegion.

Constructor Summary

Constructors

Constructor and Description
GlyphRegion(Font.GlyphRegion other) Copies another GlyphRegion.
GlyphRegion(com.badlogic.gdx.graphics.g2d.TextureRegion textureRegion, int x, int y, int width, int height) Creates a GlyphRegion from a parent TextureRegion (typically from an atlas), along with the lower-left x and y coordinates, the width, and the height of the GlyphRegion.

Method Summary

Modifier and Type	Method and Description
void	flip(boolean x, boolean y) Flips the region, adjusting the offset so the image appears to be flipped as if no whitespace has been removed for packing.

Field Detail

offsetX

public float offsetX

The offset from the left of the original image to the left of the packed image, after whitespace was removed for packing.

offsetY

public float offsetY

The offset from the bottom of the original image to the bottom of the packed image, after whitespace was removed for packing.

xAdvance

public float xAdvance

How far to move the "cursor" to the right after drawing this GlyphRegion. Uses the same unit as offsetX.

Constructor Detail

GlyphRegion

public GlyphRegion(com.badlogic.gdx.graphics.g2d.TextureRegion textureRegion,
                   int x,
                   int y,
                   int width,
                   int height)

Creates a GlyphRegion from a parent TextureRegion (typically from an atlas), along with the lower-left x and y coordinates, the width, and the height of the GlyphRegion.

Parameters:

textureRegion - a TextureRegion, typically from a TextureAtlas

x - the x-coordinate of the left side of the texture, in pixels

y - the y-coordinate of the lower side of the texture, in pixels

width - the width of the GlyphRegion, in pixels

height - the height of the GlyphRegion, in pixels

GlyphRegion

public GlyphRegion(Font.GlyphRegion other)

Copies another GlyphRegion.

Parameters:

other - the other GlyphRegion to copy

Method Detail

flip

public void flip(boolean x,
                 boolean y)

Flips the region, adjusting the offset so the image appears to be flipped as if no whitespace has been removed for packing.

Overrides:

flip in class com.badlogic.gdx.graphics.g2d.TextureRegion

Parameters:

x - true if this should flip x to be -x

y - true if this should flip y to be -y
