PRESS THE RETURN KEY TO EXECUTE THE SAVE. THIS FUNCTION WILL CREATE A FILE ON THE DRIVE YOU DESIGNATED. THE FILE WILL HAVE THE NAME YOU ASSIGNED WITH THE FILE EXTENSION (.PTN). 3.19.4. MANIPULATION OF PATTERNS ONCE A PATTERN HAS EITHER BEEN CAPTURED, OR LOADED FROM DISK, IT CAN BE MANIPULATED ON THE SCREEN. MOVE THE CURSOR DOT TO THE UPPER LEFT CORNER OF THE AREA WHERE YOU WANT TO PLACE THE PATTERN (REMEMBER WHEN WE CAPTURE A PATTERN WE DRAW AN IMAGINARY BOX AROUND IT. THE BOX THEORY STILL APPLIES). WHEN THE PATTERN IS PLACED IN THE SCREEN, IT GOES DOWN AND RIGHT FROM THE CURSOR DOT. 3.19.4.1. Alt P (LOGICAL XOR) OVERLAY WHILE HOLDING DOWN THE Alt KEY, PRESS THE P KEY. THE PATTERN WILL OVERLAY ANYTHING ALREADY ON THE SCREEN WITHOUT DESTROYING IT. IF YOU DON'T LIKE THE WAY IT LOOKS, YOU CAN REPEAT THIS FUNCTION, AND THE PATTERN WILL BE REMOVED.

NOTE WHEN USING THE LAST TWO FUNCTION, YOU WILL BE PROMPTED (PATTERN OK (Y/N) ). IF YOU ARE SATISFIED, ENTER Y. IF YOU ARE NOT SATISFIED, ENTER N AND THE SCREEN WILL BE RESTORED TO THE CONDITION BEFORE THE FUNCTION. NOTE IF YOU GET THE ERROR MESSAGE (NOT ENOUGH ROOM FOR PATTERN TO FIT!!), THIS MEANS CURSOR DOT IS EITHER TOO CLOSE TO THE RIGHT SIDE, OR TOO CLOSE TO THE BOTTOM, FOR THE PATTERN TO FIT ON THE SCREEN. MOVE THE CURSOR DOT AND TRY AGAIN. 3.20. WORKING WITH BLOCKS 3.20.1. Ctrl F7 DEFINE A BLOCK TO DEFINE A BLOCK, WE ARE GOING TO DRAW OUR IMAGINARY BOX AROUND THE AREA WE WANT TO MANIPULATE. MOVE THE CURSOR DOT TO ONE CORNER OF THE IMAGINARY BOX. WHILE HOLDING DOWN THE Ctrl KEY, PRESS THE F7 KEY. THE PROMPT LINE WILL SHOW (DEFINE BLOCK). MOVE THE CURSOR DOT TO THE DIAGONALLY OPPOSITE CORNER OF THE IMAGINARY BOX. WHEN YOU ARE SATISFIED WITH THE AREA DEFINED, PRESS THE RETURN KEY. THE PROMPT LINE WILL DISPLAY (BLOCK HAS BEEN DEFINED!). 3.20.2. Ctrl F8 DRAW A GRID INSIDE A BLOCK ONCE WE HAVE DEFINED A BLOCK, WE CAN PLACE A GRID INSIDE.

THIS TYPE OF GRID MAY BE SMALLER THAT THE AREA DEFINED IN THE BLOCK. YOU WILL BE PROMPTED (GRID OK (Y/N) ). IF YOU ARE SATISFIED WITH YOUR GRID, ENTER Y. IF YOU ARE NOT SATISFIED, ENTER N AND THE SCREEN WILL BE RESTORED TO THE CONDITION PRIOR TO THE GRID. Medium Resolution Graphics for the IBM-PC/XT YOURART1 Version 4.0 PAGE 3-8 3.20.3. MANIPULATION OF COLORS IN A BLOCK CHANGING FROM ONE COLOR TO ANOTHER, OR REVERSING THE COLORS WITHIN A SPECIFIC AREA OF THE SCREEN. 3.20.3.1.

WHILE HOLDING DOWN THE Ctrl KEY, PRESS THE F10 KEY. THE COLORS WILL BE REVERSED THE SAME AS IN A REVERSE WITHIN A BLOCK FUNCTION. THIS FUNCTION IS USED MAINLY TO PREPARE A NEGATIVE OF YOUR DRAWING BEFORE DUMPING TO A PRINTER. SOMETIMES DUMPING THE NEGATIVE OF YOUR DRAWING TO THE PRINTER IS MORE VISUALLY PLEASING THAN THE POSITIVE. 3.22. Alt C CHANGE BACKGROUND COLOR WHILE HOLDING DOWN THE Alt KEY, PRESS THE C KEY. EVERY TIME THE C KEY IS PRESS, THE BACKGROUND COLOR WILL CHANGE. THE BACKGROUND COLOR ROTATES FROM COLOR 0 through 15. WHEN COLOR 15 IS REACHED THE COLOR ROLLS OVER TO COLOR 0. 3.23.

Alt E ERASE SCREEN WHILE HOLDING DOWN THE Alt KEY, PRESS THE E KEY. YOU WILL BE PROMPTED TO SELECT EITHER ERASING ALL OF THE SCREEN OR JUST A PART OF THE SCREEN (ERASE (A)ll (P)art ). ENTERING A WILL ERASE THE ENTIRE SCREEN. ENTERING P WILL ALLOW YOU SELECTIVELY ERASE PARTS OF THE SCREEN. IF YOU WANT TO ERASE A PART OF THE SCREEN, BE SURE AND MOVE THE CURSOR DOT TO ONE CORNER OF THE AREA YOU WISH TO ERASE BEFORE USING THIS FUNCTION. USE THE CURSOR KEYS TO DEFINE THE AREA OF THE SCREEN YOU WISH TO ERASE (THIS AREA WILL BE A RECTANGULAR AREA). WHEN YOU ARE SATISFIED WITH THE AREA YOU DEFINED, PRESS THE RETURN KEY. THE AREA YOU DEFINED WILL BE ERASED. YOU WILL BE PROMPTED (ERASURE OK (Y/N) ). IF THE SCREEN WAS ERASED TO YOUR SATISFACTION ENTER Y.
