Manipulating Vector images

Extraction of raster images, embedded in vector formats

Using Aspose.Imaging for Python via .NET, developers can easily in unified way extract raster images embedded in vector formats. Example contains how to get embedded images from SVG file, but also you can use it for another vector formats.

from aspose.imaging import FileFormat, Image, VectorImage
from aspose.pycore import as_of
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
file_name = os.path.join(data_dir, "template.svg")
output_folder = data_dir
files = []


def get_extension(format_):
	tmp_switch = format_
	if tmp_switch == FileFormat.JPEG:
		return ".jpg"
	elif tmp_switch == FileFormat.PNG:
		return ".png"
	elif tmp_switch == FileFormat.BMP:
		return ".bmp"
	else:
		return "." + FileFormat(format_).name


with Image.load(file_name) as image:
	images = as_of(image, VectorImage).get_embedded_images()
	i = 0
	for im in images:
		embed_image = im.image
		out_file_name = "svg_image{0}{1}".format(i, get_extension(embed_image.file_format))
		i += 1
		out_file_path = os.path.join(output_folder, out_file_name)
		files.add(out_file_path)
		with im as _:
			embed_image.save(out_file_path)

		if delete_output:
			os.remove(out_file_path)
