seqdiag font

[Ricardo Mancera]

Hello,

I want to draw a pdf using DiagramDraw and need an example, this gives me error:

from seqdiag import parser, builder, drawer

tree = parser.parse_string(text)
diagram = builder.ScreenNodeBuilder.build(tree)
draw = drawer.DiagramDraw('pdf', diagram, filename="c:\\Results\\diagram.pdf")
draw.draw()
draw.save()

===> RuntimeError: Could not detect fonts, use --font opiton


-How do i include the font option in the function drawer.DiagramDraw ?

thank you

Hi Recard,

>-How do i include the font option in the function drawer.DiagramDraw ?

Outputting PDF requires truetype font.
You should give fontmap argument to DiagramDraw().

blockdiag.utils.bootstrap:create_fontmap() will help you to create
fontmap object.

Thanks,

Hi, 

    is there any example code about how to add truetype font use python scripts?

Thanks for your help!

[varvar debianvarvar]

after reading the code, I fixed it.

For those who also met problems in change fontmap, 

here is the sample code:

options = dict()
options['fontmap'] = ''
options['font'] = list()
options['font'].append('/usr/font/DejaVuSerif.ttf:1')
options = utils.dotdict(options)
fm = create_fontmap(options)

pdfdraw = drawer.DiagramDraw('PDF', diagram, filename=pdfname, debug=True, fontmap=fm)
pdfdraw.draw()
pdfdraw.save()

Hi,

Sorry for late response.

You can do it using following code. (I don't test it. but it will work fine)

from blockdiag.utils.fontmap import FontMap

fm = FontMap()
fm.set_default_font('/usr/font/DejaVuSerif.ttf:1')

Thanks,
