Python魔杖：如何使文字加粗？

Question

How to generate bolded text using python wand library? I cant get it to work.

http://docs.wand-py.org/en/0.4.1/wand/drawing.html - regarding documentation styles that are supported: 'undefined; 'normal' 'italic' 'oblique' 'any' there is no bold style?

sample usage i wanted to do a footer with a date that I get from contents file:

        with Image(width=150, height=25,) as img:
            draw.font_family = 'MS Reference Sans Serif'
            draw.font_size = 14.0
            draw.push()
            draw.font_style = 'italics'
            metrics = draw.get_font_metrics(img, contents['date'], multiline=False)
            draw.text(int((img.width - metrics.text_width)/2), int((metrics.text_height)), contents['date'])
            draw.pop()
            draw(img)
            img.save(filename='./temp/footer.png')

Maybe there is some way to make it bold in some quick way? Would really appreciate any help.

Answer 1

"bold" is not a font_style , it's a font_weight : http://docs.wand-py.org/en/0.4.1/wand/drawing.html#wand.drawing.Drawing.font_weight

And the integer values it takes are the values fonts typically use, where 400 is "normal" and 700 is "bold". (These are also used in CSS. See eg https://developer.mozilla.org/en-US/docs/Web/CSS/font-weight#Common_weight_name_mapping .)

Answer 2

Although mercator offered a correct answer to the title question, this answer focusing on the nested question:

Maybe there is some way to make it bold in some quick way?

Try using the bold variant typeface directly.

Either specific the bold-font file provided by Microsoft ...

draw.font = 'refsanb.ttf`

... or use the font style with a "Bold" suffix.

draw.font_family = 'MS Reference Sans Serif Bold'
