Pictures

class Pictures(impl)

A collection of all picture objects on the specified sheet:

>>> import xlwings as xw
>>> xw.books['Book1'].sheets[0].pictures
Pictures([<Picture 'Picture 1' in <Sheet [Book1]Sheet1>>,
          <Picture 'Picture 2' in <Sheet [Book1]Sheet1>>])

在 0.9.0 版本加入.

add(image, link_to_file=False, save_with_document=True, left=None, top=None, width=None, height=None, name=None, update=False, scale=None, format=None, anchor=None, export_options=None)

在指定的工作表中增加一个图片。

参数:

  • image (str | PathLike[str] | Any) -- 是文件路径名或者是Matplotlib图形对象。

  • left (float | None) -- Left position in points, defaults to 0. If you use top/left, you must not provide a value for anchor.

  • top (float | None) -- Top position in points, defaults to 0. If you use top/left, you must not provide a value for anchor.

  • width (float | None) -- Width in points. Defaults to original width.

  • height (float | None) -- Height in points. Defaults to original height.

  • name (str | None) -- Excel picture name. Defaults to Excel standard name if not provided, e.g., 'Picture 1'.

  • update (bool) -- 替换指定名字的图片，需要指定图片名字。

  • scale (float | None) -- Scales your picture by the provided factor.

  • format (str | None) -- Only used if image is a Matplotlib or Plotly plot. By default, the plot is inserted in the "png" format, but you may want to change this to a vector-based format like "svg" on Windows (may require Microsoft 365) or "eps" on macOS for better print quality. If you use 'vector', it will be using 'svg' on Windows and 'eps' on macOS. To find out which formats your version of Excel supports, see: https://support.microsoft.com/en-us/topic/support-for-eps-images-has-been-turned-off-in-office-a069d664-4bcf-415e-a1b5-cbb0c334a840

  • anchor (Range | None) -- The xlwings Range object of where you want to insert the picture. If you use anchor, you must not provide values for top/left. New in version 0.24.3.

  • export_options (dict[str, Any] | None) -- For Matplotlib plots, this dictionary is passed on to image.savefig() with the following defaults: {"bbox_inches": "tight", "dpi": 200}, so if you want to leave the picture uncropped and increase dpi to 300, use: export_options={"dpi": 300}. For Plotly, the options are passed to write_image(). New in version 0.27.7.

示例

  1. Picture

>>> import xlwings as xw
>>> sht = xw.Book().sheets[0]
>>> sht.pictures.add(r'C:\path\to\file.png')
<Picture 'Picture 1' in <Sheet [Book1]Sheet1>>

  1. Matplotlib

>>> import matplotlib.pyplot as plt
>>> fig = plt.figure()
>>> plt.plot([1, 2, 3, 4, 5])
>>> sht.pictures.add(fig, name='MyPlot', update=True)
<Picture 'MyPlot' in <Sheet [Book1]Sheet1>>
