Emboss effect is similar to Edge extraction but it is more like a 3d effect. The traditional use for Emboss is to make something look more three-dimensional by adding highlights and shadows to different parts of your layer. In order to generate an Embossed image we use emboss function in Wand. Similar to edge() function, emboss() function gives best result with grayscale image.
Syntax :
wand.image.emboss(radius=radius, sigma=std. deviation)Parameters :
Parameter Input Type Description radius numbers.Integer the radius of the, in pixels, not counting the center pixel. sigma numbers.Real Standard deviation used
Image Used :
Example #1:
# import Image from wand.image module from wand.image import Image # read image using Image function with Image(filename ="frameman.jpeg") as img: # generate a grayscale image img.transform_colorspace('gray') # GENERATE EMBOSS IMAGE img.emboss(radius = 3.0, sigma = 1.75) # SAVE FINAL IMAGE img.save(filename ="manemboss.jpeg") |
Output:
Example #2:
Increasing radius and sigma value.
# import Image from wand.image module from wand.image import Image # read image using Image function with Image(filename ="frameman.jpeg") as img: # generate a grayscale image img.transform_colorspace('gray') # GENERATE EMBOSS IMAGE img.emboss(radius = 10, sigma = 3) # SAVE FINAL IMAGE img.save(filename ="manemboss.jpeg") |
