* UserPath.h by Bruce Blumberg, NeXT Computer, Inc.
|
|
*
|
|
* You may freely copy,distribute and re-use the code in this example. NeXT
|
|
* disclaims any warranty of any kind, expressed or implied, as to its fitness
|
|
* for any particular purpose
|
|
*
|
|
* This file and its associated .m file define a data structure and set of
|
|
* functions aimed at facilitating the use of user paths. Here is a simple
|
|
* example:
|
|
*
|
|
* UserPath *arect;
|
|
* arect = newUserPath(); // creates an empty user path
|
|
* beginUserPath(arect,YES); // initialize user path and cache
|
|
* UPmoveto(arect,0.0,0.0); // add moveto to userpath; update bounding box
|
|
* UPrlineto(arect,0.0,100.0); // add rlineto to path; update bounding box
|
|
* UPrlineto(arect,100.0,0.0); // add rlineto to path; update bounding box
|
|
* UPrlineto(arect,0.0,-100.0); // add rlineto to path; update bounding box
|
|
* closePath(arect); // close path
|
|
* endUserPath(arect,dps_stroke); // close user path and specify operator
|
|
* sendUserPath(arect);
|
|
*
|
|
* As you will note, the set of routines manage the allocation and growth of
|
|
* the operator and operand arrays, as well as the calculation of the bounding
|
|
* box. A user path created via these functions may be optionally cached down
|
|
* at the window server, or repeatedly sent down. The user paths created by
|
|
* this set of functions are all allocated in a unique zone.
|
|
*
|
|
* Note: the associated file is a .m file because it pulls in some .h files
|
|
* which reference objective C methods.
