# display_parametric

## Arguments:

• _width>0,_height>0,_outline_opacity,_vertex_radius>=0,_is_antialiased={ 0 | 1 },_is_decorated={ 0 | 1 },_xlabel,_ylabel

## Description:

Render 2D or 3D parametric curve or point clouds from selected image data.

Curve points are defined as pixels of a 2 or 3-channel image.
If the point image contains more than 3 channels, additional channels define the (R,G,B) color for each vertex.
If outline_opacity>1, the outline is colored according to the specified vertex colors and
outline_opacity-1 is used as the actual drawing opacity.

## Default values:

width=512, height=width, outline_opacity=3, vertex_radius=0, is_antialiased=1,is_decorated=1, xlabel="x-axis" and ylabel="y-axis".

## Examples of use:

### • Example #1
