cmd_xorpic |
Function (ROM Call 0x39B) |
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
