Pictures¶

class Pictures(impl)¶

指定工作表中图片( picture )对象的集合:

>>> 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>>])

Added in version 0.9.0.

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。

Arguments¶

imagestr or path-like object or matplotlib.figure.Figure: 是文件路径名或者是Matplotlib图形对象。
leftfloat, default None: Left position in points, defaults to 0. If you use top/left, you must not provide a value for anchor.
topfloat, default None: Top position in points, defaults to 0. If you use top/left, you must not provide a value for anchor.
widthfloat, default None: Width in points. Defaults to original width.
heightfloat, default None: Height in points. Defaults to original height.
namestr, default None: Excel picture name. Defaults to Excel standard name if not provided, e.g., 'Picture 1'.
updatebool类型, 缺省值为False: 替换指定名字的图片，需要指定图片名字。
scalefloat, default None: Scales your picture by the provided factor.
formatstr, default 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: xw.Range, default 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.

Added in version 0.24.3.
export_optionsdict, default 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().

Added in version 0.27.7.
