Write Direct Shape Area Transparency Transparency

The ooodev.format.writer.direct.shape.transparency.Transparency class is used to modify the values seen in Fig. 848 of a shape.

Add a transparency to the shape

Adding a transparency to the shape is done by using the ShapeTransparency class.

from ooodev.format import Styler
from ooodev.format.draw.direct.transparency import Transparency as ShapeTransparency
# ... other code

rect = Draw.draw_rectangle(slide=slide, x=x, y=y, width=width, height=height)
color_style = ShapeColor(StandardColor.RED)
style = ShapeTransparency(60)
Styler.apply(rect, color_style, style)

The results of the setting the shape style can be seen in Fig. 1010.

Get Shape Transparency

We can get the style of the shape by using the ShapeTransparency.from_obj() method.

from ooodev.format.writer.direct.shape.transparency import Transparency as ShapeTransparency
# ... other code

# get the style from the shape
f_style = ShapeTransparency.from_obj(rect)
assert f_style
