PLACE()

{{Template:BuildingBlockLangImage}}

== Description ==
: You can position the drawing pen in a graphic object with the '''Place()''' method.

== Syntax ==
# #handle PLACE(x, y) - Set the position to be x, y

== Hints ==
: Place useful hints about this keyword here

The following demo positions the drawing pen, then retrieves the coordinates and prints the values in the graphics area.
<source lang="rb">
'create a graphic object
graphic #g, 800, 600

'locate the drawing pen at 10,10
#g place(10,10)

'retrieve the X coordinate of the pen
posX = #g X()

COLOR()

2021-07-04T06:00:56Z

UserStPendl:

{{Template:BuildingBlockLangImage}}

== Description ==
: Use the COLOR statement to set the drawing color in a graphic object. The default drawing color is black.

== Syntax ==
=== Named Color ===
# #handle COLOR("green")
=== RGB Color ===
# #handle COLOR("255, 128, 0")

== Hints ==
: The list of named Run BASIC colors:
:* black
:* blue
:* brown
:* chartreuse
:* cyan
:* darkCyan
:* darkGray
:* darkGreen
:* darkMagenta
:* darkRed
:* gray
:* green
:* lightCyan
:* lightGray
:* lightYellow
:* magenta
:* navy
:* olive
:* orange
:* orchid
:* paleGreen
:* pink
:* purple
:* red
:* royalBlue
:* salmon
:* springGreen
:* veryDarkGray
:* veryLightGray
:* white
:* yellow

== Example ==
<source lang="rb">
'create a graphic object
graphic #g, 300, 300

'set the drawing color to be salmon
#g color("salmon")

'place the drawing pen at 10,10
#g place(10,10)

'draw a box
#g box(290, 290)

'add graphic to web page
render #g
</source>

<source lang="rb">
'create a graphic object
graphic #g, 300, 300

'set the drawing color to be 233,88,125
#g color(233,88,125)

'place the drawing pen at 10,10
#g place(10,10)

'draw a box
#g box(290, 290)

CLS()

2021-07-04T06:00:35Z

UserStPendl:

{{Template:BuildingBlockLangImage}}

== Description ==
: The graphic CLS() statement should not be confused with the general [[CLS]] statement.

== Syntax ==
# A graphic object can be cleared to a blank rectangle with the '''CLS()''' statement. There are three possibilities for the CLS() statement.
#* #handle CLS(["color"] | [r, g, b]) - Clear the graphics area to white, or to named color, or to an RBG color

=== Clear to default white ===
# #handle CLS()

=== Clear to named color, which is a string ===
# #handle CLS("red")

=== Clear to RGB color, which is three values (0-255) separated by commas ===
# #handle CLS(255,0,128)

== Hints ==
: Place useful hints about this keyword here

== Example ==
Here is a demo that creates a graphic object, draws a circle, then causes the graphic to be displayed on the web page. It then uses CLS to clear the graphic to a named color, then again to the default white, then again to an RGB color. See also [[COLOR()]] for more information on using colors in Run BASIC graphics.
<source lang="rb">
'create a graphic object
graphic #g, 300, 300

'place the drawing pen at 100,100
#g place(100,100)

'draw a circle with radius 75
#g circle(75)

'add graphic to web page
render #g

'clear the screen to named color
#g cls("chartreuse")
render #g

'clear the screen to default white
#g cls()
render #g

'clear the screen to RGB color
#g cls(214, 120, 72)
render #g
</source>

CIRCLE()

2021-07-04T06:00:00Z

UserStPendl:

{{Template:BuildingBlockLangImage}}

== Description ==
: A '''CIRCLE''' can be drawn in a graphic object. It is drawn in the current [[COLOR()]] and the current [[SIZE()]]. The center is at the current pen position. The size of the radius is fed to the CIRCLE command. The radius of a circle is the distance from the center to the circumference of the circle.

== Syntax ==
# #handle CIRCLE(r) - Draw a circle of radius r at the current position

== Hints ==
: Place useful hints about this keyword here

== Example ==
<source lang="rb">
'create a graphic object
graphic #g, 300, 300

'place the drawing pen at 100,100
#g place(100,100)

'draw a circle with radius 75
#g circle(75)

'add graphic to web page
render #g

BOX()

2021-07-04T05:59:30Z

UserStPendl:

{{Template:BuildingBlockLangImage}}

== Description ==
: A '''BOX''' can be drawn in a graphic object. It is drawn in the current [[COLOR()]] and the current [[SIZE()]]. One corner is at the current pen position. The other corner's X,Y coordinates are fed to the BOX command.

== Syntax ==
# #handle BOX(x, y) - Draw a box from the current position to x, y

== Hints ==
: Place useful hints about this keyword here

== Example ==
<source lang="rb">
'create a graphic object
graphic #g, 300, 300

'place the drawing pen at 10,10
#g place(10,10)

'draw a box
#g box(290, 290)
