weGetPathSegWidth

weGetPathSegWidth( 
[ g_pathSegId ] 
) 
=> float

Description

Automatically handles the sqrt(2) conversion for diagonal path segments when their width is being queried. Unlike dbGetPathSegWidth which returns the value stored in the OpenAccess database for the width of diagonal pathSegs, this API does the sqrt(2) conversion appropriately and return the width value as it appears in the property editor form or object inspector assistant.

Arguments

g_pathSegID

OpenAccess database Id of the pathSeg being queried.

Value Returned

float

Returns an sqrt(2) converted width for diagonal pathSeg. For manhattan pathSegs, it returns the value of debGetPathSegWidth using ~> operator.

Examples

Consider the following examples:

Consider ortho is a manhattan pathseg whose width == 0.3

\i weGetPathSegWidth(ortho)

\t 0.3

\p >

\i ortho~>width

\t 0.3

Consider diag is a diagonal pathseg whose width == 0.3. The following script shows the use of weGetPathSegWidth versus using ~> operator with dbGetPathSegWidth. Here the diagonal width is calculated as 0.43 = mfgGrid (0.3 * sqrt(2) )

\i weGetPathSegWidth(diag)

\t 0.3

\p >

\i diag~>width

\t 0.43

\p >
