<B>LINE Draw Line or Box</B>

<B>LINE</B> [[STEP] (<U>x1</U>,<U>y1</U>)] - [STEP] (<U>x2</U>,<U>y2</U>) [,[<U>color</U>] [,B[F]]] [,<U>style</U>]
|

|
|
|
||
|
|
Draws a line or a box at specified coordinates, in a specified color.
|
||
|
|
|
||
|
|
STEP If included, coordinates are relative to last graphics
|
||
|
|
point referenced. If omitted, coordinates are absolute.
|
||
|
|
|
||
|
|
<U>x1</U>,<U>y1</U> If ,B option is used, <U>x1</U>,<U>y1</U> and <U>x2</U>,<U>y2</U> are corner
|
||
|
|
<U>x2</U>,<U>y2</U> coordinates of a rectangular box; otherwise <U>x1</U>,<U>y1</U> and
|
||
|
|
<U>x2</U>,<U>y2</U> are end points of a line.
|
||
|
|
|
||
|
|
<U>color</U> Specifies color to use . Defaults to 3 in medium
|
||
|
|
resolution, 1 in high resolution.
|
||
|
|
|
||
|
|
B Tells BASIC to draw a rectangular box instead of a line.
|
||
|
|
|
||
|
|
F Tells BASIC to fill the box.
|
||
|
|
|
||
|
|
<U>style</U> Allows you to draw a broken (dashed) line or box (see
|
||
|
|
below).
|
||
|
|
|
||

|
<B>Notes:</B> If STEP is included with <U>x2</U>,<U>y2</U> but not <U>x1</U>,<U>y1</U>, then <U>x2</U> and
|
||
|
|
<U>y2</U> are measured relative to the absolute coordinate pair
|
||
|
|
(<U>x1</U>,<U>y1</U>).
|
||
|
|
|
||
|
|
QuickBASIC treats <U>style</U> as a 16-bit integer mask, plotting
|
||
|
|
the 1 bits and skipping the 0 bits, and repeating the
|
||
|
|
pattern as many times as necessary to create the specified
|
||
|
|
line. Thus a style value of 43690 (AAAAh,
|
||
|
|
1010101010101010b) would produce an evenly dotted line or
|
||
|
|
box, with every other pixel plotted. Note that QuickBASIC
|
||
|
|
ignores the "off" pixels; it does not plot them in the
|
||
|
|
background color.
