Drawing Graphics

If you want anything other than the default line style (solid), mask (no mask), background color (black), or foreground color (white), you must call the appropriate routine before calling the drawing routine. Subsequent output routines employ the same attributes until you change them or open a new child window.

The following is a list of routines that provide information on the current graphics settings, set new graphics settings, and draw graphics:

Routine

Description

ARC, ARC_W

Draws an arc

CLEARSCREEN

Clears the screen, viewport, or text window

ELLIPSE, ELLIPSE_W

Draws an ellipse or circle

FLOODFILL, FLOODFILL_W

Fills an enclosed area of the screen with the current color index using the current fill mask

FLOODFILLRGB, FLOODFILLRGB_W

Fills an enclosed area of the screen with the current RGB color using the current fill mask

GETARCINFO

Determines the endpoints of the most recently drawn arc or pie

GETCURRENTPOSITION, GETCURRENTPOSITION_W

Returns the coordinates of the current graphics-output position

GETPIXEL, GETPIXEL_W

Returns a pixel's color index

GETPIXELRGB, GETPIXELRGB_W

Returns a pixel's Red-Green-Blue color value

GETPIXELS

Gets the color indices of multiple pixels

GETPIXELSRGB

Gets the Red-Green-Blue color values of multiple pixels

GRSTATUS

Returns the status (success or failure) of the most recently called graphics routine

INTEGERTORGB

Convert a true color value into its red, green, and blue components

LINETO, LINETO_W

Draws a line from the current graphics-output position to a specified point

LINETOAR, LINETOAREX

Draws lines from arrays at x,y coordinate points

MOVETO, MOVETO_W

Moves the current graphics-output position to a specified point

PIE, PIE_W

Draws a pie-slice-shaped figure

POLYGON, POLYGON_W

Draws a polygon

RECTANGLE, RECTANGLE_W

Draws a rectangle

RGBTOINTEGER

Convert a trio of red, green, and blue values to a true color value for use with RGB functions and subroutines

SETPIXEL, SETPIXEL_W

Sets a pixel at a specified location to a color index

SETPIXELRGB, SETPIXELRGB_W

Sets a pixel at a specified location to a Red-Green-Blue color value

SETPIXELS

Set the color indices of multiple pixels

SETPIXELSRGB

Set the Red-Green-Blue color value of multiple pixels

Most of these routines have multiple forms. Routine names that end with _W use the window-coordinate system and REAL(8) argument values. Routines without this suffix use the viewport-coordinate system and INTEGER(2) argument values.

Curved figures, such as arcs and ellipses, are centered within a bounding rectangle, which is specified by the upper-left and lower-right corners of the rectangle. The center of the rectangle becomes the center for the figure, and the rectangle's borders determine the size of the figure. In the following figure, the points (x1, y1) and (x2, y2) define the bounding rectangle.
