Convert SVG to Image, JPG, PNG, BMP, TIFF and GIF using Python

In the article, you will find information on how to convert SVG to Image file formats such as JPG, PNG, BMP, TIFF, and GIF. Image file conversion is required for website developing, graphic designers acting, photography, and other purposes. The choice of the image format depends on whether you print it in polygraphy, send it by e-mail or put an image on a webpage.

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 and SVGDocument classes.

To continue following this tutorial, you should install and configure the Aspose.SVG for Python via .NET library in your Python project. Our code examples help you to convert SVG files using the Python library.

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 example. 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 image formats programmatically in Python, please see the following conversion scenarios and Python code examples.

Convert SVG to JPG

The JPG format offers high compression rates with minimal loss of quality, making it ideal for use on the web where file size matters. It is widely supported across devices and platforms, ensuring compatibility and ease of sharing. Additionally, JPG’s ability to handle complex color variations makes it ideal for photographs and realistic images.

Using the convert_svg() method

Using convert_svg() methods is the most common way to convert SVG to various popular formats. You can convert SVG to JPG or to another format programmatically with full control over a wide range of conversion parameters. The following code snippet shows how to convert SVG to JPG and specify background color, page size, margins, and vertical & horizontal resolutions. In addition, the following Python example will show how to configure the paths to the source and output files in your file system:

• Use the set_extension() method of the Configuration class to register the SkiaSharp extension. The SkiaSharp module is a graphics library used for rendering SVG content. It ensures that the rendering engine supports the operations needed for the conversion.
• Create an instance of the ImageSaveOptions class and specify required save options:
  • Use the format property to set image format.
  • Use the background_color property to set the color that will fill the background.
  • Use the page_setup property to set paage 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 an image file.

import os
import aspose
from aspose.svg import *
from aspose.svg.converters import *
from aspose.svg.drawing.skiasharp import *
from aspose.svg.rendering import *
from aspose.svg.drawing import *
from aspose.svg.saving import *

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

# Activate the Aspose.SVG.Drawing.SkiaSharp feature
Configuration.set_extension(SkiaModule())
options = ImageSaveOptions()
options.format.JPEG
options.background_color = aspose.pydrawing.Color.from_argb(233, 255, 241)
options.page_setup.any_page = Page(Size(450, 450), Margin(20, 20, 20, 20))
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 JPG
    Converter.convert_svg(document, options, output_file)

You can evaluate the quality of conversion by trying our product. Here, we provide an illustration - the following Figure shows the original сhristmas-tree.svg image (a) and the converted the сhristmas-tree.jpg image with a new background color (b):

How to convert SVG to image

Aspose.SVG for Python via .NET supports converting SVG to image formats such as PNG, JPG, JPEG, BMP, TIFF, GIF, and WEBP. You can use the above Python code for this; to change the output image format, you only need to specify the required extension (format) in the output file name and set the format property.

For example, to convert SVG to GIF, you need:

1. to set the format property: options.format.GIF,
2. and set the extension .gif in the output image file name: output_file = os.path.join(output_folder, "image.gif").

Image 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.

Using the render_to() method

Consider how to convert a document from SVG to JPG using render_to() method:

• Initialize an SVG document using the SVGDocument() class.
• Create an instance of the ImageRenderingOptions class. If you need to set image format, horizontal and vertical resolutions, page size and margins:
  • Use the format property to set image format.
  • Use the horizontal_resolution and vertical_resolution properties to set the horizontal and vertical resolutions for output image.
  • Use the page_setup property to set page size amd margins.
• Create a new instance of the ImageDevice class.
• Convert SVG to JPG using the render_to(device) method of the SVGDocument class.

The following example shows how to apply the page_setup, horizontal_resolution and vertical_resolution properties for SVG to JPG converting:

import os
from aspose.svg import *
from aspose.svg.drawing.skiasharp import *
from aspose.svg.rendering import *
from aspose.svg.drawing import *
from aspose.svg.rendering.image import *

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

with SVGDocument(src_file) as document:
    # Initialize an instance of the ImageRenderingOptions class and set custom properties
    image_rendering_options = ImageRenderingOptions()
    image_rendering_options.format = ImageFormat.JPEG
    image_rendering_options.horizontal_resolution = Resolution.from_dots_per_inch(96.0)
    image_rendering_options.vertical_resolution = Resolution.from_dots_per_inch(96.0)
    image_rendering_options.page_setup.any_page = Page(Size(600, 600), Margin(10, 10, 10, 10))

    # Initialize an instance of the ImageDevice class
    with ImageDevice(image_rendering_options, output_file) as device:
        # Render SVG to JPG and send the document to the rendering device
        document.render_to(device)

You can use the above Python code for converting SVG to image formats such as PNG, JPG, JPEG, BMP, TIFF, GIF, and WEBP. To change the output image format, you need to specify the required extension (format) in the output file name and set the format property.

For example, to convert SVG to BMP, you only need to set the format property:

image_rendering_options.format = ImageFormat.BMP,

and set the extension .bmp in the output image file name:

output_file = os.path.join(output_folder, "image.bmp").

Image Rendering Options – ImageRenderingOptions class

The ImageRenderingOptions class in Aspose.SVG for Python via .NET provides a set of options to control how SVG documents are rendered to image formats. The ImageRenderingOptions class is used in conjunction with the specific device ImageDevice, which represents the target output image formats for the rendered SVG content.

This class allows you to fine-tune the rendering process to meet specific requirements. Here are key properties associated with the ImageRenderingOptions class:

Property	Description
compression	Sets Tagged Image File Format (TIFF) Compression. By default, this property is LZW.
css	This property gets a CssOptions object, which is used for the 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 allows you to set the background color for the rendered output. If not set, the default background 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.
