Implementation Guide

This section demonstrates how to convert OXPS files to PNG using the GroupDocs.Conversion library.

Loading and Converting OXPS File

Overview

Learn how to load an OXPS file and perform a conversion to PNG format efficiently.

1. Setting Up Paths Define paths for your input and output directories:

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string inputFile = "YOUR_DOCUMENT_DIRECTORY/SAMPLE_OXPS.oxps";
string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.png");

2. Creating a Stream for Each Page Use a function to create streams dynamically during conversion:

Func<SavePageContext, Stream> getPageStream = savePageContext =>
    new FileStream(string.Format(outputFileTemplate, savePageContext.Page), FileMode.Create);

3. Conversion Process Load the OXPS file and convert it using GroupDocs.Conversion:

using (Converter converter = new Converter(inputFile))
{
    ImageConvertOptions options = new ImageConvertOptions { Format = ImageFileType.Png };
    converter.Convert(getPageStream, options);
}

Setting Conversion Options for PNG Format

Overview

Configure image conversion settings tailored specifically for the PNG format.

1. Initializing Convert Options Start by creating an instance of ImageConvertOptions:

ImageConvertOptions options = new ImageConvertOptions();

2. Specifying Output Format Set the desired output format to PNG:

options.Format = ImageFileType.Png;

Troubleshooting Tips

  • File Path Issues: Ensure all file paths are correctly set.
  • Version Compatibility: Verify you’re using compatible versions of .NET and GroupDocs.Conversion.
