Python-pptx font .name doesn't work. How to change all fonts?
问题
我想将所有字体设置为"Calibri"，我使用以下代码成功地更改了字体大小和颜色。然而，font.name却无效。我尝试了构建另一个ppt并再次尝试，但仍然失败。
还有一个问题，我在哪里可以获取字体名称列表？
"tmp.pptx"只是通过MS PowerPoint创建的普通ppt文件。任何人都可以通过打开PowerPoint来复制这个过程。我在其中放置了一个矩形并输入了一些文本，这是在PowerPoint中完成的。现在，我想使用python-pptx包而不是MS PowerPoint将字体类型更改为'Calibri'。问题是我无法将字体类型更改为我设置的font.name='Calibri'。
运行代码后，我通过Powerpoint打开tmp.pptx，发现字体仍然是Times New Roman，没有更改为Calibri。
总之，我想知道如何将整个PPT中的所有字体从一种类型更改为另一种类型，比如Calibri\Arial等。我的意思是每个幻灯片中的每个字符都更改为我想要的字体。
ppt = pptx.Presentation('tmp.pptx')
for slide in ppt.slides:
for shape in slide.shapes:
if shape.has_text_frame:
for para in shape.text_frame.paragraphs:
# 如果使用"font=para.font"，它无法识别自动形状中的字体。要更改所有字体，应该使用"for run in para.runs"。
for run in para.runs:
font = run.font
font.size = pptx.util.Pt(20) # 成功
font.color.rgb = pptx.dml.color.RGBColor(140, 0, 0) # 成功
font.name = 'Calibri' # 失败
ppt.save('tmp.pptx')
英文:
I want to set all font to "Calibri", I use the following code to change font size,color sucessfully. font.name doesn't work however. I build a another ppt and try again, failed again.
And one more question, where can I get font name list?
"tmp.pptx" is just a common ppt file built through MS powerpoint. Any one can replicate this by open powerpoint. I put a rectangle in it and type some text, which was done in powerpoint. Now I want change the font type to 'Calibri' by using python-pptx pacakage rather than MS powerpoint. The problem is I can not change font type to what I set font.name='Calibri".
After running the code, I open tmp.pptx through Powerpoint and found that the font remains Times New Roman, it didn't change to Calibri.
In a word, How can I change all fonts from one type to another type such as Calibri\Arial whatever in the entire PPT. I mean every character in every slide change to the font I want.
ppt=pptx.Presentation('tmp.pptx')
for slide in ppt.slides:
for shape in slide.shapes:
if shape.has_text_frame:
for para in shape.text_frame.paragraphs:
#If use "font=para.font",It can not identify font in autoshape. To change all fonts, a "for run in para.runs" should be used.
for run in para.runs:
font=run.font
font.size=pptx.util.Pt(20)#succeeded
font.color.rgb=pptx.dml.color.RGBColor(140,0,0)#succeeded
font.name='Calibri'#failed
ppt.save('tmp.pptx')

你可以按照以下方式获取字体名称：
from pptx.text.fonts import FontFiles
fonts = FontFiles._installed_fonts()
font_names = [i[0] for i in fonts]
请注意，这是获取字体名称的代码示例。
英文:
You can get font names like this
from pptx.text.fonts import FontFiles
fonts = FontFiles._installed_fonts()
font_names = [i[0] for i in fonts]
