    Modifier and Type
    Field
    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
    Description
    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.
    GlyphRegion​(Font.GlyphRegion other)
    Copies another GlyphRegion.

  • Method Summary

    Method
    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 Details

    • 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 Details

    • 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 Details

    • 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
