[英]Python-pptx - Inserting a picture into a shape & animations
I'm trying to make a python script using python-pptx but I struggle with inserting a picture into a shape.我正在尝试使用 python-pptx 制作 python 脚本,但我很难将图片插入到形状中。 Basically, I need it for making the picture transparent ( https://www.shapechef.com/blog/make-image-transparent-in-powerpoint ).
基本上,我需要它来使图片透明( https://www.shapechef.com/blog/make-image-transparent-in-powerpoint )。
One more thing, I'd like to make a button into the presentation for showing/hiding the picture (trying to make it in python).还有一件事,我想在演示文稿中制作一个按钮以显示/隐藏图片(尝试在 python 中制作)。 I ain't sure how to use animations in python-pptx, can you help me with this?
我不知道如何在 python-pptx 中使用动画,你能帮我吗?
Much appreciated, thank you.非常感谢,谢谢。 Raz

Adding the code I have for making a shape with transparency (just need to insert a picture into it):添加我用于制作具有透明度的形状的代码(只需在其中插入图片):
from pptx import Presentation
from pptx.oxml.xmlchemy import OxmlElement
from pptx.util import Cm
from pptx.enum.shapes import MSO_SHAPE
from pptx.dml.color import RGBColor
def SubElement(parent, tagname, **kwargs):
element = OxmlElement(tagname)
element.attrib.update(kwargs)
parent.append(element)
return element
def _set_shape_transparency(shape, alpha):
""" Set the transparency (alpha) of a shape"""
ts = shape.fill._xPr.solidFill
sF = ts.get_or_change_to_srgbClr()
sE = SubElement(sF, 'a:alpha', val=str(alpha))
## Create presentation
prs = Presentation()
## Add a slide (empty slide layout)
slide = prs.slides.add_slide(prs.slide_layouts[6])
##Add a blue box to the slide
# MSO_FILL_TYPE = MSO_FILL.PICTURE
blueBox = slide.shapes.add_shape(autoshape_type_id=MSO_SHAPE.RECTANGLE,
left=Cm(0),
top=Cm(0.54),
height=Cm(17.97),
width=Cm(25.4))
## Make the box blue
blueBoxFill = blueBox.fill
blueBoxFill.solid()
blueBoxFillColour = blueBoxFill.fore_color
blueBoxFillColour.rgb = RGBColor(0,176,240)
## Set the transparency of the blue box to 56%
_set_shape_transparency(blueBox,44000)
## Save the presentation
prs.save('test.pptx')
With Aspose.Slides for Python , you can easily apply image transparency to shapes.使用Aspose.Slides for Python ,您可以轻松地将图像透明度应用于形状。 The following code example shows you how to do this:
以下代码示例向您展示了如何执行此操作:
import aspose.slides as slides
# Create a new presentation.
with slides.Presentation() as presentation:
# Add an image to resources of the presentation.
with open("dog.png", "rb") as image_stream:
image = presentation.images.add_image(image_stream)
# Add a rectangle shape.
rectangle = presentation.slides[0].shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 50, 50, 200, 200)
# Use the picture fill for the shape.
rectangle.fill_format.fill_type = slides.FillType.PICTURE
rectangle.fill_format.picture_fill_format.picture.image = image
# Set the image transparency to 50%.
rectangle.fill_format.picture_fill_format.picture.image_transform.add_alpha_modulate_fixed_effect(50)
# Save the presentation.
presentation.save("example.pptx", slides.export.SaveFormat.PPTX)
