Textual Wmf to Png conversion in Python

Support textual Wmf to Png conversion

Issue : When converting WMF file to PNG, the text position and style can change.

Tips : It is necessary to change the RenderMode property to AUTO in WmfRasterizationOptions.

Example :

import aspose.pycore as aspycore
from aspose.imaging import Image, SizeF
from aspose.imaging.imageoptions import WmfRasterizationOptions, PngOptions
from aspose.imaging.fileformats.wmf import WmfRenderMode
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 = "template.wmf"
input_file_name = os.path.join(templates_folder, file_name)
output_file_name = input_file_name + ".png"
with Image.load(input_file_name) as image:
	obj_init = WmfRasterizationOptions()
	obj_init.render_mode = WmfRenderMode.AUTO
	obj_init.page_size = aspycore.cast(SizeF, image.size)
	rasterization_options = obj_init
	obj_init2 = PngOptions()
	obj_init2.vector_rasterization_options = rasterization_options
	image.save(output_file_name, obj_init2)

if delete_output:
	os.remove(output_file_name)
