Examples

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

from aspose.imaging import Image, Graphics, Color, GraphicsPath, Figure, RectangleF, Rectangle, Size
from aspose.imaging import Point, PointF, Pen
from aspose.imaging.imageoptions import BmpOptions
from aspose.imaging.sources import FileCreateSource
from aspose.imaging.shapes import EllipseShape, PieShape, ArcShape, PolygonShape, RectangleShape
from os.path import join as path_join

#Creates an instance of BmpOptions and set its various properties            
with BmpOptions() as bmpOptions:
	bmpOptions.bits_per_pixel = 24
	#Create an instance of FileCreateSource and assign it as Source for the instance of BmpOptions
	#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 
	with Image.create(bmpOptions, 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
		graphicspath = GraphicsPath()
		#Create an instance of Figure class
		figure1 = Figure()
		# Add Shape to Figure object
		figure1.add_shape(EllipseShape(RectangleF(50, 50, 300, 300)))
		figure1.add_shape(PieShape(Rectangle(Point(110, 110), Size(200, 200)), 0, 90))
		# Create an instance of Figure class
		figure2 = Figure()
		# Add Shape to Figure object
		figure2.add_shape(ArcShape(RectangleF(10, 10, 300, 300), 0, 45))
		figure2.add_shape(
			PolygonShape([PointF(150, 10), PointF(150, 200), PointF(250, 300), PointF(350, 400)], True))
		figure2.add_shape(RectangleShape(RectangleF(Point(250, 250), Size(200, 200))))
		# Add Figure object to GraphicsPath
		graphicspath.add_figures([figure1, figure2])
		# Draw path with Pen object of color Black
		graphics.draw_path(Pen(Color.black, 2.0), graphicspath)
		# save all changes.
		image.save()
