Constructor Detail

GraphicsLCDCanvas

public GraphicsLCDCanvas()

create a GraphicsLCDCanvas with the default size of 128x64 pixels

Method Detail

setDefaultSize

public void setDefaultSize()

setSize

public void setSize(int n_columns,
                    int n_rows)

createDefaultColors

public void createDefaultColors()
