since all of the title images still had 8.2, and the title text still said 7.3 or 7.4, having not been updated for a long time.

<H3>Summary:</H3>
|
|
<BLOCKQUOTE>
|
|
The <B>cutbox</B> command generates a clipping rectangle on the
|
|
layout. This is used for two purposes: Limiting the amount of
|
|
output to generate for a large layout, and to create vertical
|
|
or orthogonal cross-sections of a layout. <P>
|
|
|
|
<B>cutbox none</B> removes any existing cutbox. <B>cutbox box</B>
|
|
creates a cutbox equal to the cursor box boundary. Otherwise,
|
|
<B>cutbox</B> is followed by two coordinate pairs representing
|
|
the cutbox lower-left and upper-right corners, in <B>magic</B>
|
|
(<I>not</I> CIF/GDS) units. <P>
|
|

|
<H3>Implementation Notes:</H3>
|
|
<BLOCKQUOTE>
|
|
<B>cutbox</B> is implemented as a built-in <B>wind3d</B>
|
|
window command in <B>magic</B>. It can only be invoked from
|
|
a window created with the <B>specialopen wind3d</B> command,
|
|
or the <B>render</B> procedure. Note that the <B>wind3d</B>
|
|
window is only available when magic is compiled with the OpenGL
|
|
graphics option and invoked with <B>magic -d OGL</B>. <P>
|
|
|
|
Note that macros of the <B>wind3d</B> window are hard-coded,
|
|
and cannot be changed with the <B>macro</B>, <B>gmacro</B>, or
|
|
<B>imacro</B> commands. There is no "<TT>:</TT>" macro for
|
|
entering commands; to enter commands from the command-line,
|
|
use the <A HREF=../tk_path_name.html> <I>tk_path_name</I></A>
|
|
command. The default Tk path name of the <B>wind3d</B> window
|
|
is "<TT>.magic3d</TT>".
