PxlLine CATALOG PxlLine rowStart, colStart, rowEnd, colEnd [, drawMode] Displays the Graph screen and draws a line between pixel coordinates (rowStart, colStart) and (rowEnd, colEnd), including both endpoints. If drawMode = 1, draws the line (default). If drawMode = 0, turns off the line. If drawMode = -1, turns a line that is on to off or off to on (inverts pixels along the line). Note: Regraphing erases all drawn items. See also Line. PxlOff CATALOG PxlOff row, col PxlOff rowList, colList Displays the Graph screen and turns off the pixel at pixel coordinates (row, col). Note: Regraphing erases all drawn items.

Note: Regraphing erases all drawn items. 25,50 PxlOn 25,50 ¸ pxlTest() CATALOG pxlTest (row, col) ⇒ Boolean expression pxlTest (rowList, colList) ⇒ Boolean expression Returns true if the pixel at pixel coordinates (row, col) is on. Returns false if the pixel is off. Note: Regraphing erases all drawn items.
