pdftricks – Sup­port for pstricks in pdfTeX

The PSTricks macros can­not be used (di­rectly) with pdfTeX, since pstricks uses PostScript arith­metic, which isn't part of PDF. This pack­age cir­cum­vents this lim­i­ta­tion so that the ex­ten­sive fa­cil­i­ties of­fered by the pow­er­ful PSTricks pack­age can be made use of in a pdfTeX doc­u­ment. This is done us­ing the shell es­cape func­tion avail­able in cur­rent TeX im­ple­men­ta­tions.
The pack­age may also be used in sup­port of other ‘PostScript-out­put-only’ pack­ages, such as PSfrag.
For al­ter­na­tives, users may care to re­view the dis­cus­sion in the PSTricks on­line doc­u­men­ta­tion.
