rgba2rgb(rgba, background=(1, 1, 1))

Parameters

rgba : (..., 4) array_like

The image in RGBA format. Final dimension denotes channels.

background : array_like

The color of the background to blend the image with (3 floats between 0 to 1 - the RGB value of the background).

Raises

ValueError

If :None:None:`rgba` is not at least 2-D with shape (..., 4).

Returns

out : (..., 3) ndarray

The image in RGB format. Same dimensions as input.

RGBA to RGB conversion using alpha blending .

Examples

This example is valid syntax, but we were not able to check execution

>>> from skimage import color
... from skimage import data
... img_rgba = data.logo()
... img_rgb = color.rgba2rgb(img_rgba)

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
