Method Detail

align

public Coord3d align(float textWidth,
                     float textHeight,
                     Horizontal horizontal,
                     Vertical vertical,
                     Coord2d offset,
                     Coord3d screen)

Compute final text position on screen according to the layout parameters and initial screen position.

Parameters:

textWidth - width of the text in pixel

textHeight - height of the text font in pixel

horizontal - horizontal alignment

vertical - vertical alignment

offset - an (x,y) offset to apply to the base position once X and Y alignment are processed

screen - base 2D position of the text on screen before applying layout (Z dimension is used to indicate how far is the text in the 3D scene, given as a ratio between the near and far clipping plane of the camera)

align

public Coord3d align(float textWidth,
                     float textHeight,
                     Horizontal horizontal,
                     Vertical vertical,
                     Coord3d screen)

Compute final text position on screen according to the layout parameters and initial screen position.

Parameters:

textWidth - width of the text in pixel

textHeight - height of the text font in pixel

horizontal - horizontal alignment

vertical - vertical alignment

screen - base 2D position of the text on screen before applying layout (Z dimension is used to indicate how far is the text in the 3D scene, given as a ratio between the near and far clipping plane of the camera)

computeXAlign

public float computeXAlign(float textWidth,
                           Horizontal horizontal,
                           Coord3d screenPosition,
                           float x)

computeYAlign

public float computeYAlign(float textHeight,
                           Vertical vertical,
                           Coord3d screenPosition,
                           float y)
