python wand: creating text dropshadow

Have anyone tried creating dropshadow with python wand? I went through this doc and couldn't find dropshadow attribute.

http://docs.wand-py.org/en/0.4.1/wand/drawing.html

According to imagemagick it is possible by doing below: http://www.imagemagick.org/Usage/fonts/

   convert -size 320x100 xc:lightblue -font Candice -pointsize 72 \
           -fill black -draw "text 28,68 'Anthony'" \
           -fill white -draw "text 25,65 'Anthony'" \
           font_shadow.jpg

How can I adapt this in python?

Have anyone tried creating dropshadow with python wand?

There's a few techniques, and examples if you search the tag.

I went through this doc and couldn't find dropshadow attribute.

You would not see an attribute, as the dropshadow is nonsensical in vector drawing context. (at least I think)

Here's one approach / method for creating text dropshadows.

  1. Draw shadow
  2. Apply filter (optional)
  3. Draw text
from wand.color import Color
from wand.compat import nested
from wand.drawing import Drawing
from wand.image import Image

dimensions = {'width': 450,
              'height': 100}

with nested(Image(background=Color('skyblue'), **dimensions),
            Image(background=Color('transparent'), **dimensions)) as (bg, shadow):
    # Draw the drop shadow
    with Drawing() as ctx:
        ctx.fill_color = Color('rgba(3, 3, 3, 0.6)')
        ctx.font_size = 64
        ctx.text(50, 75, 'Hello Wand!')
        ctx(shadow)
    # Apply filter
    shadow.gaussian_blur(4, 2)
    # Draw text
    with Drawing() as ctx:
        ctx.fill_color = Color('firebrick')
        ctx.font_size = 64
        ctx.text(48, 73, 'Hello Wand!')
        ctx(shadow)
    bg.composite(shadow, 0, 0)
    bg.save(filename='/tmp/out.png')

Creating Text dropshadow

Edit Here's another example that matches the Usage example.

from wand.color import Color
from wand.drawing import Drawing
from wand.image import Image

# -size 320x100 xc:lightblue
with Image(width=320, height=100, background=Color('lightblue')) as image:
    with Drawing() as draw:
        # -font Candice
        draw.font = 'Candice'
        # -pointsize 72
        draw.font_size = 72.0
        draw.push()
        # -fill black
        draw.fill_color = Color('black')
        # -draw "text 28,68 'Anthony'"
        draw.text(28, 68, 'Anthony')
        draw.pop()
        draw.push()
        # -fill white
        draw.fill_color = Color('white')
        # -draw "text 25,65 'Anthony'"
        draw.text(25, 65, 'Anthony')
        draw.pop()
        draw(image)
    # font_shadow.jpg
    image.save(filename='font_shadow.jpg')
