# Create text stamp
textStamp = apdf.TextStamp("Sample Stamp")
# Set whether stamp is background
textStamp.background = True
# Set origin
textStamp.x_indent = 100
textStamp.y_indent = 100
# Rotate stamp
textStamp.rotate = apdf.Rotation.ON90
# Set text properties
textStamp.text_state.font = apdf.text.FontRepository.find_font("Arial")
textStamp.text_state.font_size = 14
textStamp.text_state.font_style = apdf.text.FontStyles(
    apdf.text.FontStyles.BOLD | apdf.text.FontStyles.ITALIC )
textStamp.text_state.foreground_color = apdf.Color.aqua
# Add stamp to particular page
document.pages[1].add_stamp(textStamp)
