Python Svgwrite和字体样式/大小

[英]Python Svgwrite and font styles/ sizes

我正在尝试将SVG文件连接到Web scraper。

如何使用svgwrite更改字体和文本大小? 我知道我必须定义一个CSS样式,并以某种方式将其连接到文本对象。 但是这是怎么做的?

这是我到目前为止的代码

import svgwrite

svg_document = svgwrite.Drawing(filename = "test-svgwrite3.svg",
                            size = ("1200px", "800px"))
#This is the line I'm stuck at
#svg_document.add(svg_document.style('style="font-family: Arial; font-size  : 34;'))

svg_document.add(svg_document.rect(insert = (900, 800),
                                   size = ("200px", "100px"),
                                   stroke_width = "1",
                                   stroke = "black",
                                   fill = "rgb(255,255,0)"))

svg_document.add(svg_document.text("Reported Crimes in Sweden",
                                   insert = (410, 50),
                                   fill = "rgb(255,255,0)",

                                  #This is the connection to the first line that I'm stuck at
                                  #style = 'style="font-family: Arial; font-size  : 104;'))

print(svg_document.tostring())

svg_document.save()

SvgWrite的制造商Manfred Moitzi寄给我一个更加精心的答案;

这必须由CSS完成,使用'class_'或'style'关键字args来设置文本属性:

dwg = svgwrite.Drawing()

使用'style'关键字arg:

g = dwg.g(style="font-size:30;font-family:Comic Sans MS, Arial;font-weight:bold;font-
style:oblique;stroke:black;stroke-width:1;fill:none")

g.add(dwg.text("your text", insert=(10,30))) # settings are valid for all text added to 'g'
dwg.add(g)

使用'class_'关键字arg:

创建包含内容的CSS文件:

.myclass {
font-size:30;
font-family:Comic Sans MS, Arial;
font-weight:bold;
font-style:oblique;
stroke:black;
stroke-width:1;
fill:none;
}

请参阅CSS参考: http//www.w3schools.com/cssref/default.asp

dwg.add_stylesheet(filename, title="sometext") # same rules as for html files

g = dwg.g(class_="myclass")
g.add(dwg.text("your text", insert=(10,30))) # settings are valid for all text added to 'g'
dwg.add(g)

使用'class_'和'style'关键字args,您可以设置每个图形对象的样式,并且可以在容器对象中使用它们。

答案很简单;

svg_document.add(svg_document.text("Reported Crimes in Sweden",
                                   insert = (410, 50),
                                   fill = "rgb(255,255,0)",
                                   style = "font-size:10px; font-family:Arial"))

像这样设置font-size:

dwg = svgwrite.Drawing('test.svg', profile='tiny')
dwg.add(dwg.text('Test',insert = (30, 55),font_size="10px",fill='black'))
