Here you will find Python code examples for SVG to PNG conversion with default save options and with exactly specified conversion options. The article provides a general description of the conversion features of Aspose.SVG for python via .NET and describes supported scenarios of SVG to Image conversions by using Converter class.

Online SVG Converter

You can convert SVG to images and other popular formats in any way – online or programmatically. Check the Aspose.SVG API functionality and convert SVG in real-time! Please load SVG from a local file system or URL, select the output format and run the converter. In the example, the save options are set by default. You will immediately receive the result as a separate file.

If you want to convert SVG to PNG programmatically, please see the following conversion scenarios and Python examples.

Convert SVG to PNG – Using the convert_svg() method

The PNG (Portable Network Graphics) format is a widely used image format known for its lossless compression, which means it preserves all the details of an image without losing quality during compression. It supports transparency, making it ideal for web graphics, logos, and images with transparent backgrounds. PNG is popular because it offers high image quality, excellent compression ratio, and wide compatibility with various applications and web browsers. Additionally, it supports a wide range of colors and is suitable for images that require editing and resaving.

Using convert_svg() methods is the most common way to convert SVG to various popular formats. The following code snippet shows how to convert SVG to PNG with default save options:

• Create an instance of the ImageSaveOptions class.
• Open a source SVG document using the SVGDocument class.
• Use the convert_svg() method to convert and save SVG as a PNG file.

from aspose.svg import SVGDocument
from aspose.svg.saving import ImageSaveOptions
from aspose.svg.converters import Converter

options = ImageSaveOptions()
with SVGDocument("document.svg") as document:

    # Convert SVG to PNG
    Converter.convert_svg(document, options, "result.png")

Save Options – ImageSaveOptions Class

Aspose.SVG allows converting SVG to Image file formats using default or custom save options. ImageSaveOptions usage enables you to customize the rendering process. For example, you can specify the image format, page size, margins, background color, etc.

Property	Description
compression	Sets Tagged Image File Format (TIFF) Compression. By default, this property is LZW.
css	Gets a CssOptions object which is used for configuration of CSS properties processing.
format	Sets the ImageFormat (JPG, PNG, BMP, TIFF, or GIF). By default, this property is PNG.
background_color	This property sets the color that will fill the background. By default, this property is transparent.
page_setup	This property allows you to define the layout of the page, including dimensions and margins.
horizontal_resolution	Sets the horizontal resolution for output and internal images in pixels per inch (dpi). By default, this property is set to 300 dpi, which is used unless overridden by specific conditions. The resolution is always applied unless the Page size is set in pixels (px), in which case the default resolution is 96 dpi.
vertical_resolution	Sets the vertical resolution for output and internal images in pixels per inch (dpi). By default, this property is set to 300 dpi, which is used unless overridden by specific conditions. The resolution is always applied unless the Page size is set in pixels (px), in which case the default resolution is 96 dpi.
smoothing_mode	This property sets the rendering quality for this image.
text	Gets a TextOptions object which is used for configuration of text rendering.

Note: The options that are implementing with the ImageSaveOptions class are inheriting from the ImageRenderingOptions class.

Convert SVG to PNG using save options

The following Python example shows how to use ImageSaveOptions and convert SVG to PNG with custom save options. In addition, the following Python example will show how to configure the paths to the source and output files in your file system.

• Create an instance of the ImageSaveOptions class and specify required save options:
  • Use the background_color property to set the color that will fill the background.
  • Use the page_setup property to set page size amd margins.
  • Use the horizontal_resolution and vertical_resolution properties to set the horizontal and vertical resolutions for output image.
• Open a source SVG document using the SVGDocument class.
• Use the convert_svg() method to convert and save SVG as a PNG file.

import os
from aspose.svg import SVGDocument
from aspose.svg.converters import Converter
from aspose.svg.saving import ImageSaveOptions
from aspose.svg.drawing import Resolution, Page, Size, Margin
from aspose.pydrawing import Color

# Initialize an SVG document from a file
input_folder = "data/"
output_folder = "output/"
src_file = os.path.join(input_folder, "winter.svg")
output_file = os.path.join(output_folder, "winter.png")
if not os.path.exists(output_folder):
    os.makedirs(output_folder)

options = ImageSaveOptions()
options.background_color = Color.from_argb(231, 217, 230)
options.page_setup.any_page = Page(Size(600, 550), Margin(10, 10, 10, 10))
options.horizontal_resolution = Resolution.from_dots_per_inch(96.0)
options.vertical_resolution = Resolution.from_dots_per_inch(96.0)
with SVGDocument(src_file) as document:

    # Convert SVG to PNG
    Converter.convert_svg(document, options, output_file)
