在python和matplotlib生成的PPTX中向图片(图)添加边框

Question

​

我有一个由matplotlib生成的图，然后将它保存为.png，然后使用pptx模块将它放在PPT文件中。我想在我的PPT文件中添加图片的边框，谁能帮我写代码..？

from pptx.util import Inches
from pptx import Presentation

prs = Presentation('dashboard.pptx')
left = Inches(0.5)
top = Inches(1)
slide = prs.slides.add_slide(prs.slide_masters[0].slide_layouts[2])
pic = slide.shapes.add_picture('test.png',left, top,width =None ,height =None)
prs.save('dashboard_new.pptx')

Answer 1

python中的Picture对象具有一个line属性，该属性提供对边框属性的访问：

• http://python-pptx.readthedocs.org/en/latest/api/shapes.html#picture-objects
• http://python-pptx.readthedocs.org/en/latest/api/dml.html#pptx.dml.line.LineFormat

所以代码会像这样：

from pptx.dml.color import RGBColor

line = pic.line
line.color.rgb = RGBColor(0xFF, 0x00, 0x00)
line.width = Inches(0.1)

Answer 2

形状(在本例中是pic对象)具有一个.Line属性，该属性控制形状周围的边框。下面是一个如何在VBA中添加行的示例。在您的示例中，您将修改pic对象的相同.Line属性：

Sub AddBorder()

    Dim oSh As Shape

    ' this assumes that the current shape is selected
    ' in other cases, you'd work with an object reference
    ' generated when you added the shape
    Set oSh = ActiveWindow.Selection.ShapeRange(1)

    With oSh
        ' if you don't set the line to be visible,
        ' you get odd results
        .Line.Visible = msoTrue
        .Line.ForeColor.RGB = RGB(255, 0, 0)
        .Line.Weight = 6    ' in points
    End With

End Sub
