AMS 1.01 or higher | bascmd.h

void cmd_xorpic (SYM_STR SymName, CESI y, CESI x);

Executes TI-Basic 'XorPic' command.

cmd_xorpic displays the Graph Screen and logically XORs the picture stored in the TI-Basic variable pointed to by SymName (a VAT variable string, see SYMSTR) into the current graph screen at the pixel coordinates determined by the values pointed to by y and x, respectively. Both x and y should point to integer items. SymName should be the name of a PIC variable.
See BitmapPut for much faster low-level manipulations with bitmap pictures, independently of the Graph Screen.

Uses: GetValue, HToESI, gr_active, GraphActivate, DerefSym, VarRecall, WinBitmapPut
