Figure Class

Summary: The figure. A container for shapes.

Module: aspose.imaging

Full Name: aspose.imaging.Figure

Inheritance: ObjectWithBounds

Constructors

Name	Description
Figure()	Initializes a new Figure instance. A constructor required for a JSON deserialization.

Properties

Name	Type	Access	Description
bounds	RectangleF	r	Gets or sets the object’s bounds.
is_closed	bool	r/w	Gets or sets a value indicating whether this figure is closed. A closed figure will make a difference only in case where the first and the last figure’s shapes are continuous shapes. In such case the first point of the first shape will be connected by a straight line from the last point of the last shape.
segments	ShapeSegment[]	r	Gets the whole figure segments.
shapes	Shape[]	r	Gets the shapes.

Methods

Name	Description
add_shape(shape)	Adds a shape to the figure.
add_shapes(shapes)	Adds a range of shapes to the figure.
get_bounds(matrix)	Gets the object’s bounds.
get_bounds(matrix, pen)	Gets the object’s bounds.
remove_shape(shape)	Removes a shape from the figure.
remove_shapes(shapes)	Removes a range of shapes from the figure.
reverse()	Reverses this figure shapes order and shapes point order.
transform(transform)	Applies the specified transformation to the shape.

Constructor: Figure()

 Figure() 

Initializes a new Figure instance.
A constructor required for a JSON deserialization.

 get_bounds(matrix) 

Gets the object’s bounds.

Parameters:

Parameter	Type	Description

 remove_shapes(shapes) 

Removes a range of shapes from the figure.

Parameters:

Parameter	Type	Description
shapes	Shape[]	The shapes range to remove.

Method: transform(transform)

 transform(transform) 

Applies the specified transformation to the shape.

Parameters:

Parameter	Type	Description
transform	Matrix	The transformation to apply.

Examples

This examples make use of GraphicsPath and Graphics classes to create and manipulate figures on an Image surface. Example creates a new Image (of type Tiff), clears the surface and draws paths with the help of GraphicsPath class. At the end draw_path method exposed by Graphics class is called to render the paths on surface.

from aspose.imaging import Image, Graphics, Color, GraphicsPath, Figure, RectangleF, PointF, SizeF
from aspose.imaging import Pen
from aspose.imaging.sources import StreamSource
from aspose.imaging.imageoptions import TiffOptions
from aspose.imaging.fileformats.tiff.enums import TiffExpectedFormat
from aspose.imaging.shapes import RectangleShape, EllipseShape, PieShape


# Create an instance of a file stream
with open(r"C:\temp\output.tiff", "w+b") as stream:
	# Create an instance of TiffOptions and set its various properties
	tiffOptions = TiffOptions(TiffExpectedFormat.DEFAULT)
	# Set the source for the instance of ImageOptions
	tiffOptions.source = StreamSource(stream)
	# Create an instance of Image
	with Image.create(tiffOptions, 500, 500) as image:
		# Create and initialize an instance of Graphics class
		graphics = Graphics(image)
		# Clear Graphics surface
		graphics.clear(Color.wheat);
		# Create an instance of GraphicsPath class
		graphics_path = GraphicsPath()
		# Create an instance of Figure class
		figure = Figure()
		# Add Shapes to Figure object
		figure.add_shape(RectangleShape(RectangleF(10.0, 10.0, 300.0, 300.0)))
		figure.add_shape(EllipseShape(RectangleF(50.0, 50.0, 300.0, 300.0)))
		figure.add_shape(PieShape(RectangleF(PointF(250.0, 250.0), SizeF(200.0, 200.0)), 0.0, 45.0))
		# Add Figure object to GraphicsPath
		graphics_path.add_figure(figure)
		# Draw path with Pen object of color Black
		graphics.draw_path(Pen(Color.black, 2.0), graphics_path)
		# save all changes.
		image.save()

This example creates a new Image and draws a variety of shapes using figures and GraphicsPath on the Image surface

	#Second Boolean parameter determines if the file to be created IsTemporal or not
	bmpOptions.source = FileCreateSource(r"c:\temp\output.bmp", False)
	#Create an instance of Image
