Removes a specified color from an image and replaces it with transparent pixels. This
transformation is ideal for removing solid background colors from product images
photographed on clean, consistent backgrounds without any shadows. You can enter a hex
value or click the color picker to select the color to remove.
Important: We’re making
experimental features available for you to try so we can include your feedback in our
development process. The Remove Color transformation is still under development and is
subject to change without notice. It may be replaced or even removed and is not intended
for use in a production capacity. We do however, encourage you to use Remove Color in
staging or on pre-production traffic and of course, to
email us with your feedback!
The Tolerance option defines how close the color needs to be to the selected color before
it's changed to fully transparent. By default Tolerance is set at a value of 0.2. Set
the Tolerance to 0.0 to remove only the exact color specified. The maximum permitted
Tolerance is 1.0.
The Remove Color transformation may create a hard edge around an image. To
minimize these hard edges and make the removal of the color more gradual in appearance,
use the Feather option. This option allows you to extend the color removal beyond the
specified Tolerance. The pixels in this extended tolerance become semi-transparent -
creating a softer edge. By default the feather option is disabled (set to 0.0).
Note: The first realtime request for an
image using the feather option may result in a slow transformation time. Subsequent
requests are not impacted as they are served directly out of cache.
If you add the IMQuery transformation to a policy, use the im
variable, and select Remove Color, you can use a query string to remove a specified
color from an image and replace it with transparent pixels. See Syntax and Examples for
the syntax for the query string parameter.
