Parameters:

imageSource - the source of the shape's texture, either a String path, a URL, a BufferedImage, or null.

See Also:

ShapeAttributes.getImageSource()

See Also:

ShapeAttributes.getInteriorMaterial()

setInteriorOpacity

public void setInteriorOpacity(double opacity)

Specifies the opacity of the shape's interior as a floating-point value in the range 0.0 to 1.0. A value of 1.0 specifies a completely opaque interior, and 0.0 specifies a completely transparent interior. Values in between specify a partially transparent interior.

Specified by:

setInteriorOpacity in interface ShapeAttributes

Parameters:

opacity - the interior opacity as a floating-point value from 0.0 to 1.0.

See Also:

ShapeAttributes.getInteriorOpacity()

setOutlineMaterial

public void setOutlineMaterial(Material material)

Specifies the material properties of the shape's outline. If lighting is applied to the shape, this specifies the outline's ambient, diffuse, and specular colors, its shininess, and the color of any emitted light. Otherwise, the material's diffuse color specifies as the shape's constant outline color.

Specified by:

setOutlineMaterial in interface ShapeAttributes

Parameters:

material - the material to apply to the shape's outline.

See Also:

ShapeAttributes.getOutlineMaterial()

setOutlineOpacity

public void setOutlineOpacity(double opacity)

Specifies the opacity of the shape's outline as a floating-point value in the range 0.0 to 1.0. A value of 1.0 specifies a completely opaque outline, and 0.0 specifies a completely transparent outline. Values in between specify a partially transparent outline.

Specified by:

See Also:

ShapeAttributes.getOutlineOpacity()

setOutlineStippleFactor

public void setOutlineStippleFactor(int factor)

Specifies the number of times each bit in the outline stipple pattern should be repeated before the next bit is used. For example, if factor is 3, each bit is repeated 3 times before using the next bit. The specified factor must be either zero or an integer greater than zero. The factor may be limited by an implementation-defined maximum during rendering. The maximum stipple factor is typically 256.

To disable outline stippling, either specify a stipple factor of 0, or specify a stipple pattern of all 1 bits: 0xFFFF.

Specified by:

setOutlineStippleFactor in interface ShapeAttributes

Parameters:

factor - the number of times each bit in the outline stipple pattern should be repeated.

See Also:

ShapeAttributes.getOutlineStippleFactor(), ShapeAttributes.setOutlineStipplePattern(short)

setOutlineStipplePattern

public void setOutlineStipplePattern(short pattern)

Specifies a 16-bit integer that defines which pixels are rendered in the shape's outline. Starting at the least significant bit and moving to the most significant bit, the 16 bits define a repeating a pattern of which pixels in the outline are rendered and which are suppressed. Each bit corresponds to a pixel in the shape's outline, and the bit pattern repeats after reaching n*16 pixels, where n is the stipple factor. Each bit is repeated n-times according to the outline stipple factor. For example, if the outline stipple factor is 3, each bit is repeated 3 times before using the next bit.

To disable outline stippling, either specify a stipple factor of 0, or specify a stipple pattern of all 1 bits: 0xFFFF.

Specified by:

setOutlineStipplePattern in interface ShapeAttributes

Parameters:

pattern - a 16-bit integer whose bit pattern defines which pixels are rendered in the shape's outline.

See Also:

ShapeAttributes.getOutlineStipplePattern(), ShapeAttributes.setOutlineStippleFactor(int)

setOutlineWidth

public void setOutlineWidth(double width)

Specifies the line width (in pixels) to use when rendering the shape's outline. The specified width must be zero or a positive floating-point value. Specifying a line width of zero disables the shape's outline. The width may be limited by an implementation-defined maximum during rendering. The maximum width is typically 10 pixels.

Specified by:

setOutlineWidth in interface ShapeAttributes

Parameters:

width - the line width in pixels.

See Also:

ShapeAttributes.getOutlineWidth()

setUnresolved

public void setUnresolved(boolean unresolved)

Specifies whether some of the shape's attributes are unresolved. This can be used to denote that a shape's attributes are being retrieved from a non-local resource. During retrieval, the controlling code sets unresolved to true, then sets it to false once the retrieval is complete. Code that interprets the attributes knows that the attributes are complete when unresolved is false.

Specified by:

setUnresolved in interface ShapeAttributes

Parameters:

unresolved - true to specify that one or more attributes are unresolved, otherwise false.

See Also:

ShapeAttributes.isUnresolved()
