python-pillowHow to add watermark to image
To add watermark, we first make it transparent with putalpha() and then merge our initial image with it:
from PIL import Image
im = Image.open('/var/www/examples/heroine.png')
im_merge = Image.open('/var/www/examples/watermark.png')
im_merge.putalpha(100)
im.paste(im_merge, (0, 0), im_merge)
im.show()ctrl + cPILimport Pillow package modules | Image.openopen given image with Pillow |
.putalpha(change transparency of an image | .paste(paste given image to the current image |
(0, 0)coordinates to place watermark at | .show()displays resulting image |
Usage example
from PIL import Image
im = Image.open('/var/www/examples/heroine.png')
im_merge = Image.open('/var/www/examples/watermark.png')
im_merge.putalpha(100)
im.paste(im_merge, (0, 0), im_merge)
im.show()
