Chart2 Direct General Transparency

Overview

The style_area_transparency_*() method can be used to set chart transparency.

Setup

General setup for examples.

from __future__ import annotations
import uno
from pathlib import Path
from ooodev.calc import CalcDoc, ZoomKind
from ooodev.utils.color import StandardColor
from ooodev.loader.lo import Lo


def main() -> int:
    with Lo.Loader(connector=Lo.ConnectPipe()):
        fnm = Path.cwd() / "tmp" / "col_chart.ods"
        doc = CalcDoc.open_doc(fnm=fnm, visible=True)
        Lo.delay(500)
        doc.zoom(ZoomKind.ZOOM_100_PERCENT)

        sheet = doc.sheets[0]
        sheet["A1"].goto()
        chart_table = sheet.charts[0]
        chart_doc = chart_table.chart_doc
        _ = chart_doc.style_area_color(color=StandardColor.GREEN_LIGHT2)
        _ = chart_doc.style_area_transparency_transparency(50)

        Lo.delay(1_000)
        doc.close()
    return 0

Transparency

Before setting the background transparency of the chart is seen in Fig. 829.

Setting Transparency

The style_area_transparency_transparency() method can be used to set the transparency of a chart.

_ = chart_doc.style_area_color(color=StandardColor.GREEN_LIGHT2)
_ = chart_doc.style_area_transparency_transparency(50)

The results can bee seen in Fig. 480 and Fig. 481.

Getting the transparency from a Chart

# ... other code

f_style = chart_doc.style_area_transparency_transparency_get()
assert f_style is not None

Gradient Transparency

Before setting the background gradient transparency of the chart is seen in Fig. 829.

Setting Gradient

The style_area_transparency_gradient() method can be used to set the gradient transparency of a chart.

from ooodev.utils.data_type.intensity_range import IntensityRange
# ... other code

_ = chart_doc.style_area_transparency_gradient(angle=30, grad_intensity=IntensityRange(0, 100))

The results can bee seen in Fig. 482 and Fig. 483.
