Image Vectorization – Convert BMP to SVG

Vectorization involves replacing bitmaps with mathematical curves and geometric shapes, which are then saved as SVG files. Aspose.SVG for Python via. NET API offers a high-speed Python library for various SVG parsing tasks. Here, we’ll show you how to convert BMP to SVG vector graphics in Python using the Aspose.SVG Python library. On the other hand, online Image Vectorizer allows you to vectorize images in real-time, providing fast and high-quality conversions. Try the Image Vectorizer right now!


Online Image Vectorizer

Ready to transform your pixel art into crisp vector graphics? Image Vectorizer converts raster images into vector graphics using geometric shapes, Bezier curves, splines, paths, and lines. After vectorization, all elements are saved in SVG files. Image Vectorizer supports a variety of bitmap formats, including JPEG, PNG, BMP, ICO, GIF, and TIFF. Easily manipulate your vectorized SVG image with interactive controls linked to vectorization options. Convert your images into scalable, clear vector art today!




How to vectorize BMP 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 an image to a vector with default vectorization options.


Convert BMP 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

# Vectorize an image
src_file = "input.bmp"  # Specify the input BMP file
output_file = "output.svg"  # Specify the output SVG file

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


Steps to convert BMP to SVG with default vectorization options

To vectorize BMP 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. Vectorize BMP from the specified file. Use the vectorize() method to vectorize the source BMP file.
  5. Save the vectorized BMP 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, 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, PNG, BMP, TIFF, ICO, and GIF bitmap images into vector graphics.

FAQ

1. How can I vectorize BMP?

Aspose.SVG allows you to convert BMP to SVG in any way – online or programmatically. For example, you can vectorize BMP 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 BMP 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.
