How to convert JPG to vector image in Python

Aspose.SVG for Python via .NET API provides classes and methods that allow you to implement the process of vectorizing images and work with various options for pre-processing images before saving them in vector format. You can control the following vectorization parameters: trace_smoother, error_threshold, max_iterations, path_builder, stencil, etc. To find out how to do this, see, for example, the Vectorize PNG page.

In the following code example, we convert JPG to SVG with default vectorization options.


Convert JPG to SVG in Python

import os
from aspose.svg import *
from aspose.svg.imagevectorization import *

# Configuration for image vectorization
path_builder = BezierPathBuilder()

vectorizer = ImageVectorizer()
vectorizer.configuration.path_builder = path_builder

# Convert JPG to vector image
src_file = "input.jpg"  # Specify the input JPG file
output_file = "output.svg"  # Specify the output SVG file

with vectorizer.vectorize(src_file) as document:
    document.save(output_file)


Steps to convert JPG to SVG with default vectorization options

To Vectorize JPG with Aspose.SVG Python library, you should follow a few steps:

  1. Import the necessary modules and classes from the aspose.svg and aspose.svg.imagevectorization packages.
  2. Create an instance of the BezierPathBuilder class to define the path-building strategy.
  3. Create an instance of the ImageVectorizer and set its configuration to use the BezierPathBuilder.
  4. Convert JPG to vector image from the specified file. Use the vectorize() method to vectorize the source JPG file.
  5. Save the vectorized JPG image as an SVG file using the save() method on the resulting SVGDocument.

Vectorization Options

You can apply custom settings to get the best result from the image vectorization. Below are some of the main settings you can control, along with their default values. Please refer to the Vectorize PNG page for a Python example of image vectorization using custom parameters.

  1. tolerance – determines the maximum error tolerance allowed for a point to be eliminated from the trace. It must be between 0 and 4. The default value is 0.3.
  2. error_threshold – defines the maximum deviation of points to the fitted curve. By default, it is 30.
  3. max_iterations – defines a number of iterations for the least-squares approximation method. By default, it is 30.
  4. background_color – the default value is transparent white.
  5. colors_limit – sets the maximum number of colors used to quantize an image. The default value is 25.
  6. line_width – sets the line width. The value of this parameter is affected by the graphics scale. The default value is 1.
  7. image_size_limit – maximal dimension of an image determined by the multiplication of image width and height. The size of the image will be scaled based on this property. The default value is 1800000.

Image Vectorization is the process of converting raster images into vector graphics, such as Bezier curves, paths, and lines. In the documentation chapter Image and Text Vectorization , you will find detailed information about image vectorization, including a description of the process and available options. Learn how to vectorize raster images like PNG, JPG, JPEG, BMP, TIFF, GIF, and ICO into an SVG document. The chapter also includes several examples demonstrating the functionalities of the Aspose.Svg.ImageVectorization namespace and the effects of configuration properties on the results.

Aspose.SVG offers a Free Online Image Vectorizer that allows you to convert JPG, JPEG, PNG, BMP, TIFF, ICO, and GIF bitmap images into vector graphics. With this application, you can apply various options to achieve the perfect result. Save time and experience the benefits of vector graphics by trying out this Image Vectorizer today!


FAQ

1. How can I vectorize JPG?

Aspose.SVG allows you to convert JPG to SVG in any way – online or programmatically. For example, you can vectorize JPG in real-time using Online Image Vectorizer that converts your images quickly and with high quality. On other hand, you can use Aspose.SVG to vectorize JPG programmatically.

2. What is a raster to vector conversion?

The process of image conversion from raster to vector is called image vectorization. It is a complex computational process that converts a bitmap image made up of pixels into a vector image made up of lines, curves, and other geometric shapes.

3. What is the image vectorization for?

Vector images are essential for any professional who works with drawings, graphics, or sketches. Many designers, printers, architects, and artists often choose to work with sketches or drawings as vector images. And they have good reasons! Unlike bitmap graphics, vector arts are resizable and scalable without losing any quality, and they will still display just as clearly. Also, vectorization can be used to update or recover images.
Vector images are what you need to produce banners, logos, maps, signs, embroideries, engravings, graphs, blueprints, etc.

4. How is the vectorization occur?

The vectorization process uses color image quantization – a technique that reduces the number of different colors used in an image, intending that the new image should be as visually similar as possible to the original one. Then, the Vectorizer replaces all the same colored spots or pixels with geometric shapes or curves using a set of contour tracing algorithms. The final step is to convert the tracing points to SVG path lines and Bezier curves and add them to the SVG document.
