Apply gradient to a style

Before applying Style

Draw dialog Area Gradient style default — Fig. 879 Draw dialog Area Gradient style default

Apply style

The gradient can be loaded from a preset using the PresetGradientKind class as a lookup.

# ... other code

style_modify = Gradient.from_preset(
    preset=PresetGradientKind.MAHOGANY,
    style_name=FamilyGraphics.DEFAULT_DRAWING_STYLE,
    style_family=DrawStyleFamilyKind.GRAPHICS,
)
doc.apply_styles(style_modify)

After applying style

Dialog after applying style.

Draw dialog Area Gradient style changed — Fig. 880 Draw dialog Area Gradient style changed

Shape after applying style.

Shape after Style applied — Fig. 881 Shape after Style applied

Getting the area image from a style

We can get the area image from the document.

# ... other code
f_style = Gradient.from_style(
    doc=doc.component,
    style_name=FamilyGraphics.DEFAULT_DRAWING_STYLE,
    style_family=DrawStyleFamilyKind.GRAPHICS,
)
assert f_style is not None
