void Show_Edge_Weight | ( | float * | weight | ) |
Returns the edge weight that has been set on the currently open segment.
weight | Scale factor applied to edge-line widths in the currently open segment. Passed by reference. Returned to user. |
When the value being passed back is a string, be sure you've declared your string variable to be long enough.
In C, "passed by reference" means that you have to allocate an appropriate variable, either statically or off the stack, and pass a pointer to that variable to the HOOPS routine. To generate a pointer to a variable C, you prefix the variable with a "&". In other languages you normally don't have to do anything different from usual.
The Show_Edge_Weight routines will complain if they're called and the attribute is not actually set in the segment. Use Show_Existence() to avoid this, if necessary.
void QShow_Edge_Weight | ( | const char * | segment, | |
float * | weight | |||
) |
Similar to Show_Edge_Weight() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
weight | Scale factor applied to edge-line widths in the currently open segment. Passed by reference. Returned to user. |
void Show_Net_Edge_Weight | ( | float * | weight | ) |
Similar to Show_Edge_Weight(), but returns the net effective setting rather than the local one.
weight | Scale factor applied to edge-line widths in the currently open segment. Passed by reference. Returned to user. |
void PShow_Net_Edge_Weight | ( | int | keycount, | |
HC_KEY * | pathkeys, | |||
float * | weight | |||
) |
Similar to Show_Net_Edge_Weight(), but returns the net effective setting along a discreet segment path.
keycount | The size of pathkeys | |
pathkeys | An array of HC_KEY's delineating a path of segments. | |
weight | Scale factor applied to edge-line widths in the currently open segment. Passed by reference. Returned to user. |
void QShow_Net_Edge_Weight | ( | const char * | segment, | |
float * | weight | |||
) |
Similar to Show_Net_Edge_Weight() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
weight | Scale factor applied to edge-line widths in the currently open segment. Passed by reference. Returned to user. |
