A value of 4 willĮvaluate each pixels top-bottom, & left-right

  • connectivity ( numbers.Integral) – Either 4, or 8.
  • fuzz = 0.1 * QUANTUM_RANGE # 10% objects = img.
  • gravity – Calculate the top & left values based onįrom wand.image import Image from wand.version import QUANTUM_RANGE with Image ( filename = 'objects.gif' ) as img : img.
  • arguments ( basestring) – Additional numbers given as a geometry string, orĬomma delimited values.
  • top ( numbers.Integral) – the row offset of the composited source image.
  • left ( numbers.Integral) – the column offset of the composited source image.

  • operator ( basestring) – the operator that affects how the composite.
  • (the receiver image becomes the destination)
  • image ( Image) – the composited source image.
  • composite_channel ( channel, image, operator, left=None, top=None, arguments=None, gravity=None ) ¶Ĭomposite two images using the particular channel.
  • 'background' replaces full-transparent color with background color.Ĭhanged in version 0.5.3: Optional gravity argument was added.
  • 'remove' will composite background_color value.
  • 'shape' is identical to 'copy', but will color the resulting image with the value defined with background_color.
  • 'copy' calculates the gray-scale of RGB channels, and applies it to alpha channel.
  • 'extract' copies data in alpha channel across all other channels, and disables alpha channel.

  • 'transparent' enables alpha/matte channel, and forces full transparent image.
  • 'opaque' enables alpha/matte channel, and forces full opaque image.
  • 'set' enables and resets any data in an images alpha channel.
  • 'associate' & 'disassociate' toggle alpha channel flag in certain image-file specifications.
  • 'deactivate', 'off', or False will disable an images alpha channel.
  • 'activate', 'on', or True will enable an images alpha channel.
  • It can also be used to enable/disable alpha channel, but with differentīehavior of setting alpha_channel is defined with the ( bool) Get state of image alpha channel.
