Convert EPUB to JPG in Python

EPUB is an open XML-based format for digital books and publications designed for optimal viewing on various devices. Converting EPUB files to other formats is often necessary to leverage different capabilities and features of those formats. JPG files can contain high-quality image data with lossless compression. This unique compression feature allows to quickly and efficiently share JPG images and use them widely on the Web, computers, and mobile devices. With Aspose.HTML for Python via .NET, you can convert EPUB to JPG format programmatically with full control over a wide range of conversion parameters.

Convert EPUB to JPG

To convert EPUB to JPG using ImageSaveOptions, you should follow a few steps:

1. Open an existing EPUB file. In the example, we use the open() method to open and read an EPUB file from the file system at the specified path.
2. Create a new ImageSaveOptions object with JPEG image format. By default, the format property is PNG. Here, you can set the required save options, such as page setup or resolution.
3. Use one of the convert_epub() methods of the Converter class to convert EPUB to JPG. In the following example, you need to pass the EPUB file stream, ImageSaveOptions, and output file path to the convert_epub() method.

Look at the following Python code snippet that shows how to convert EPUB to JPG with custom save options using Aspose.HTML for Python via .NET.

# Convert EPUB to JPG using Python with custom settings

import os
import aspose.html.converters as conv
import aspose.html.saving as sav
import aspose.html.rendering.image as rim
import aspose.html.drawing as dr
import aspose.pydrawing as pd

# Setup directories and define paths
output_dir = "output/"
input_dir = "data/"
os.makedirs(output_dir, exist_ok=True)

document_path = os.path.join(input_dir, "input.epub")
save_path = os.path.join(output_dir, "epub-to-image.jpg")

# Open an existing EPUB file for reading
with open(document_path, "rb") as stream:

    # Create an instance of ImageSaveOptions
    options = sav.ImageSaveOptions(rim.ImageFormat.JPEG)
    options.horizontal_resolution = dr.Resolution.from_dots_per_inch(150.0)
    options.vertical_resolution = dr.Resolution.from_dots_per_inch(150.0)
    options.background_color = pd.Color.bisque
    options.page_setup.any_page.size = dr.Size(500, 1000)

    # Convert EPUB to JPG
    conv.Converter.convert_epub(stream, options, save_path)

Save Options – ImageSaveOptions Class

The ImageSaveOptions class in Aspose.HTML for Python via .NET offers extensive customization options for converting EPUB content to various image formats, ensuring high-quality output tailored to your needs. Here’s a more detailed description of each property of ImageSaveOptions:

• The format property lets you specify the output image format, such as PNG, JPEG, BMP, GIF, or TIFF, with PNG as the default.
• The page_setup property enables precise control over the page layout, including size and margins, for optimal content placement.
• The background_color property sets the background color, with transparency as the default.
• The css property, managed through CssOptions, dictates how CSS properties are handled during conversion.
• The horizontal_resolution and vertical_resolution properties, defaulting to 300 dpi, define the pixel resolution per inch for internal and output images, enhancing image sharpness.
• The use_antialiasing property adjusts graphics rendering quality, which is crucial for achieving smooth, professional-grade images.
• The compression property specifies the compression method for TIFF files, supporting options like LZW, CCITT3, CCITT4, RLE, and NONE, which helps balance file size and image quality.
• The text property offers configurations for text rendering, ensuring clear and accurate text output in the converted images.
