Draw Direct Shape Line Arrow Styles

The ooodev.format.draw.direct.line.ArrowStyles class is used to modify the values seen in Fig. 851 of a shape.

Add a Line Properties to the shape

Adding a Line Arrow Styles to the shape is done by using the ArrowStyles class.

from ooodev.format.draw.direct.line import ArrowStyles, GraphicArrowStyleKind

# ... other code

line = slide.draw_line(x1=x, y1=y, x2=x + width, y2=y + height)
style = ArrowStyles(
    start_line_name=GraphicArrowStyleKind.ARROW_LARGE,
    start_line_center=True,
    start_line_width=2.5,
    end_line_name=GraphicArrowStyleKind.SQUARE_45,
    end_line_center=False,
    end_line_width=1.9,
)
style.apply(line.component)

The results of the setting the shape line properties can be seen in Fig. 852.

Get Shape Line Arrow Styles

We can get the line arrow styles of the shape by using the ArrowStyles.from_obj() method.

from ooodev.format.draw.direct.line import ArrowStyles
# ... other code

# get the properties from the shape
f_style = ArrowStyles.from_obj(line.component)
assert f_style is not None
assert f_style.prop_start_line_name == GraphicArrowStyleKind.ARROW_LARGE.value
