I am referring to @fmw42 and his wonderful ImageMagic command to turn a white background to a transparent background. I modified his original command to work with the latest version of ImageMagick.
magick test_imagemagick.jpg -fuzz 25% -fill none -draw "alpha 0,0 floodfill" -channel alpha -blur 0x1 -level 50x100% +channel result.png
This is great on the command line, but I am struggling with understanding how to implement the same in Python Wand.
This is what I have so far which is not much because I have no idea how to map the info from both documentation.s
with Image(filename= 'test_imagemagick.jpg') as img:
img.fuzz = 0.25 * QUANTUM_RANGE # 25%
img.fill_color = 'transparent'
Try this command in Python/Wand:
from wand.image import Image
from wand.drawing import Drawing
from wand.color import Color
from wand.display import display
with Image(filename='logo:') as img:
with img.clone() as copied:
copied.fuzz = 0.25 * img.quantum_range
with Drawing() as draw:
draw.fill_color = Color('transparent')
draw.matte(x=0.0, y=0.0, paint_method='floodfill')
draw(copied)
copied.alpha_channel = 'extract'
copied.blur(radius=0.0, sigma=2)
copied.level(black=0.5, white=1, gamma=1.0)
img.composite(copied, left=0, top=0, operator='copy_opacity')
img.format='png'
display(img)
img.save(filename='logo_transparent_antialiased.png')
