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>scalegrid</B> command sets the ratio of magic internal
|
|
units to lambda units by rescaling the internal database and
|
|
appropriate technology parameters. The values <I>a</I> and
|
|
<I>b</I> are interpreted to mean that all positions in the
|
|
database should be multiplied by the factor <I>b</I> / <I>a</I>.
|
|
An equivalent meaning is that there should be <I>b</I> internal
|
|
units per <I>a</I> lambda units in the database. For example,
|
|
<BLOCKQUOTE>
|
|
<B>scalegrid 1 2</B>
|
|
</BLOCKQUOTE>
|
|
means 2 internal units per lambda, or an internal grid that is
|
|
twice as finely spaced as the default. The grid scaling can
|
|
be queried using the <B>tech lambda</B> command. Grid scaling
|
|
is interpreted relative to the current scale, so
|
|
<BLOCKQUOTE>
|
|
<B>scalegrid 1 2</B> <BR>
|
|
<B>scalegrid 1 2</B>
|
|
</BLOCKQUOTE>
|
|
results in 4 internal units per lambda.

<H3>Implementation Notes:</H3>
|
|
<BLOCKQUOTE>
|
|
<B>scalegrid</B> is implemented as a built-in command in <B>magic</B>.
