im2frame

Convert image to movie frame.

Syntax

• F = im2frame(RGB)
• F = im2frame(X, map)
• F = im2frame(X)

Input argument

• RGB - m-by-n-by-3 numeric array: Truecolor image, defined as an m-by-n-by-3 numeric array. For images of data type double, the values must be within the range [0, 1].
• X - m-by-n matrix of integers: Indexed image (double or uint8)
• map - c-by-3 numeric matrix: Colormap linked to the indexed image X, defined as a c-by-3 numeric matrix with values ranging from [0, 1]. Each row of the matrix represents an RGB triplet, specifying the red, green, and blue components of a colormap color.

Output argument

• F - a structure: Movie frame with two fields: cdata and colormap.

Description

F = im2frame(RGB) converts the truecolor image RGB into a movie frame F.

F = im2frame(X, map) converts the indexed image X along with its colormap map into a movie frame F.

F = im2frame(X) converts the indexed image X into a movie frame F, using the current colormap.

Example

examples_directory = [modulepath('graphics', 'root'), '/', 'examples/'];
edit([examples_directory, 'movie/demo_movie.m']);
run([examples_directory, 'movie/demo_movie.m']);
