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
$ gmic 1024,1,1,2,'t=x/40;if(c==0,sin(t),cos(t))*(exp(cos(t))-2*cos(4*t)-sin(t/12)^5)' display_parametric 512,512

Command: 1024,1,1,2,'t=x/40;if(c==0,sin(t),cos(t))*(exp(cos(t))-2*cos(4*t)-sin(t/12)^5)' display_parametric 512,512
• Example #2
$ gmic 1000,1,1,2,u(-100,100) quantize 4,1 noise 12 channels 0,2 +normalize 0,255 append c display_parametric 512,512,0.1,8
