void Show_Text_Spacing | ( | float * | spacing | ) |
Returns the text spacing that has been set on the currrently open segment.
spacing | A scalar describing the spacing of text characters. |
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_Text_Spacing 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_Text_Spacing | ( | const char * | segment, | |
float * | spacing | |||
) |
Similar to Show_Text_Spacing() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
spacing | A scalar describing the spacing of text characters. |
void Show_Net_Text_Spacing | ( | float * | spacing | ) |
Similar to Show_Text_Spacing(), but returns the net effective setting rather than the local one.
spacing | A scalar describing the spacing of text characters. |
void PShow_Net_Text_Spacing | ( | int | keycount, | |
HC_KEY * | pathkeys, | |||
float * | spacing | |||
) |
Similar to Show_Net_Text_Spacing(), but returns the net effective setting along a discrete segment path.
keycount | The size of pathkeys | |
pathkeys | An array of HC_KEY's delineating a path of segments. | |
spacing | A scalar describing the spacing of text characters. |
void QShow_Net_Text_Spacing | ( | const char * | segment, | |
float * | spacing | |||
) |
Similar to Show_Net_Text_Spacing() but operates on a given segment rather than the currently open one.
segment | The segment to query. | |
spacing | A scalar describing the spacing of text characters. |
