How to draw an image

Several methods are available for drawing graphics primitives such as draw_line, draw_ellipse, draw_rect draw_arc, draw_bezier and draw_string. In the beginning, we create a graphic surface to draw an image and describe graphic properties. In our example, we will create a surface with a size of 100 x 100 pixels and a color depth of 32 bits per pixel and set the background to yellow color with Clear method. Next, we define a drawing tool - a Pen object with a Blue color, to draw a dotted line or use SolidBrush for continuous lines with different colors, followed by X and Y coordinates of the start and end points of the lines:

	import aspose.pycore as aspycore
	from aspose.imaging import Image, Pen, Color, Graphics, Point
	from aspose.imaging.imageoptions import BmpOptions
	from aspose.imaging.sources import FileCreateSource
	from aspose.imaging.brushes import SolidBrush
	import os


	if 'TEMPLATE_DIR' in os.environ:
	templates_folder = os.environ['TEMPLATE_DIR']
	else:
	templates_folder = r"C:\Users\USER\Downloads\templates"

	delete_output = 'SAVE_OUTPUT' not in os.environ

	data_dir = templates_folder
	out_file = os.path.join(data_dir, "result.bmp")
	# Create an instance of BmpOptions and set its various properties
	with BmpOptions() as save_options:
	save_options.bits_per_pixel = 32
	# Set the Source for BmpOptions and create an instance of Image
	save_options.source = FileCreateSource(out_file, False)
	with Image.create(save_options, 100, 100) as image:
	# Create and initialize an instance of Graphics class and clear Graphics surface
	graphic = Graphics(image)
	graphic.clear(Color.yellow)
	# Draw two dotted diagonal lines by specifying the Pen object having blue color and co-ordinate Points
	graphic.draw_line(Pen(Color.blue), 9, 9, 90, 90)
	graphic.draw_line(Pen(Color.blue), 9, 90, 90, 9)
	# Draw a four continuous line by specifying the Pen object having Solid Brush with red color and two point structures
	graphic.draw_line(Pen(SolidBrush(Color.red)), Point(9, 9), Point(9, 90))
	graphic.draw_line(Pen(SolidBrush(Color.aqua)), Point(9, 90), Point(90, 90))
	graphic.draw_line(Pen(SolidBrush(Color.black)), Point(90, 90), Point(90, 9))
	graphic.draw_line(Pen(SolidBrush(Color.white)), Point(90, 9), Point(9, 9))
	image.save()

	if delete_output:
	os.remove(out_file)
