Add Fill Patterns
Fill Pattern() sets the pattern for filled areas.
Matrix Example
Specify a mask (a matrix of values between 0 and 1) or an image. Each value in the matrix creates a pixel.
win = New Window( "Example",
Graph Box(
Fill Pattern(
[1 0.5 0 0, 0.5 0 0 1, 0 0 1 0.5, 0 1 0.5 0]
);
Polygon( [10 30 90], [88 22 44] );
)
);
Named Pattern Example
Specify a name in quotation marks that corresponds to a pattern shown in Table 12.3.
win = New Window( "Named Pattern Example",
Graph Box(
Fill Pattern( "vertical light" );
Polygon( [10 30 90], [88 22 44] );
)
);
Graphic Example
Specify an image in quotation marks. If the image is not installed on the viewer’s computer, question marks appear in the shape.
win = New Window( "Graphic Example",
Graph Box(
Fill Pattern( Open( "$SAMPLE_IMAGES/pi.gif", "gif" ) );
Polygon( [10 30 90], [88 22 44] );
)
);
