[NTG-context] Re: Hiding a part of a path

Dear Mikael, As you said, it might be good to use image. Since I want not to draw a part of the path, I’d like to use the following code. pic := image(origin--(2u,0)--(3u,u); (3u,0)--(4u,0);); Thank you for the reply. Best regards, Dalyoung

Dear all,

I’d like to hide a part of a path.

I can do that after changing it into an image, but it is not clearly erased. Is there a way to do that not changing it into an image? Thank you for reading.

Best regards,

Dalyoung

\startMPcode path p,q; picture pic; numeric u; u:= 1cm;

p := origin--(2u,0)--(3u,u)--(3u,0)--(4u,0); q := (3u,u)--(3u,0); pic := image(draw p; draw q withcolor white;);

draw pic; \stopMPcode

It is not clear how general you want this to be. For your example you can draw only the parts of p you need.

\startMPpage[offset=1DK] path p,q; picture pic; numeric u; u:= 1cm;

p := origin--(2u,0)--(3u,u)--(3u,0)--(4u,0); q := (3u,u)--(3u,0); % pic := image(draw p; draw q withcolor white;); % draw pic; draw p withpen pencircle scaled 4 ; draw subpath (0,2) of p && subpath (3,4) of p withpen pencircle scaled 2 withcolor yellow ; \stopMPpage

If you need to "cut" in a more advanced way, I suggest to give such an example.
