Hi<br> You need to add up the colors of the surrounding pixels and average it out.<br>So you'd do something like <br>PSET(x,y),(POINT(x,y)+POINT(x+1,y)+POINT(x-1,y)+POINT(x,y-1)+POINT(x,y+1))\5<br>for each pixel on the line, after you enter graphics mode.<br><br>If you want to see some cool demo effects, come to <A HREF=" TARGET="_new">
hey this code is neat itll make a random image<br>then turn it into a plasma like image enjoy 
<br><---code starts here---><br>SCREEN 13<br>FOR x = 1 TO 101<br>FOR y = 1 TO 101<br>PSET (x, y), RND * 255<br>NEXT<br>NEXT<br>DO<br>FOR y = 1 TO 101<br> FOR x = 1 TO 101<br> c = (POINT(x - 1, y) + POINT(x + 1, y) + POINT(x, y - 1) + POINT(x, y + 1) + POINT(x, y) + POINT(x, y) + POINT(x + 1, y + 1) + POINT(x - 1, y + 1) + POINT(x + 1, y - 1) + POINT(x - 1, y - 1)) / 10<br> IF c < 1 THEN c = 1<br> PSET (x, y), c<br> NEXT x<br>NEXT y<br>e = e + 1<br>LOOP UNTIL e = 10<br><---code ends here--->

If anybody hasn't tried it yet, this is the graphic output (at 1/2 scale):<br><img src= might try smoothing the display a little with a couple GET and PUT statements. The output is a little smoother in the early stages.<br><br>Insert these lines at the top:<br>DIM yLn(1600)<br>DIM xLn(1600)<br><br>Insert these after the PSET command:<br>x2 = 101 - x<br>GET (x, 1)-(x, 101), xLn<br>PUT (x2, 1), xLn, PSET<br><br>And insert these after the NEXT x:<br>y2 = 101 - y<br>GET (1, y)-(101, y), yLn<br>PUT (1, y2), yLn, PSET<br><br>This is what it looks like:<br><img src= if you had signed on as a member I could have given you a tipmaster vote.<br> <p> <br><a href=mailto: > </a><br><a href= plain black box</a><br>
Oh, PPS:<br>If you place a RANDOMIZE TIMER command after the SCREEN command you will end up with a different image every time.<br><br>I like this discussion. It stimulates growth.<br> <p> <br><a href=mailto: > </a><br><a href= plain black box</a><br>
