vol.imagestack: Turn volume into an ImageMagick image stack.

In fsbrain: Managing and Visualizing Brain Surface Data

Turn volume into an ImageMagick image stack.

Description

Create an image from each slice along the axis, then stack those into an ImageMagick image stack.

Usage

vol.imagestack(volume, axis = 1L, intensity_scale = 255)

Arguments

volume	a 3D image volume. Can be numeric, or something that can be read directly by magick::image_read in 2D matrices (slices along the axis), e.g., a 3D array of color strings. If a 2D matrix is passed, the resulting stack will contain a single image.
axis	positive integer in range 1L..3L or an axis name, the axis to use.
intensity_scale	integer, value by which to scale the intensities in the volume to the range '[0, 1]'. Only used for numeric volumes. Set to NULL for data that can be read directly by magick::image_read, and to 1 for intensity data that requires no scaling. Defaults to 255, which is suitable for 8 bit image data.

Value

a vectorized ImageMagick image, containing one subimage per slice. This can be interpreted as an animation or whatever.
