// Initialize Converter object with source HTML file path
Converter converter = new Converter("YOUR_DOCUMENT_DIRECTORY/sample.html");

Implementation Guide

Feature: HTML to PSD Conversion

This feature allows converting an HTML document into a multi-page PSD format, perfect for graphic design and editing.

Overview:

GroupDocs.Conversion enables transforming web pages into high-fidelity PSD files, allowing designers to edit layouts in their preferred graphics software.

Implementation Steps

Step 1: Define Output Directory Paths

Specify where your converted files will be saved before conversion:

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string outputFileTemplate = Path.Combine(outputFolder, "converted-page-{0}.psd");

Explanation: The outputFileTemplate is used for naming each page’s PSD file.

Step 2: Create Stream for Each Page Conversion

Define a function to create a stream for writing each converted page:

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

Explanation: This lambda function generates a file path for each PSD page and opens a FileStream to write the output.

Step 3: Load Source HTML File

Load your source HTML file using the Converter class:

using (Converter converter = new Converter("YOUR_DOCUMENT_DIRECTORY/sample.html"))
{
    // Conversion process will be executed within this block.
}

Explanation: The Converter object initializes with the path to your HTML document, preparing it for conversion.

Step 4: Set Conversion Options

Specify the conversion options for PSD format:

ImageConvertOptions options = new ImageConvertOptions { Format = ImageFileType.Psd };

Explanation: This configuration tells GroupDocs.Conversion to convert your HTML into a PSD file.

Step 5: Perform the Conversion

Execute the conversion using the specified stream function and conversion options:

converter.Convert(getPageStream, options);

Explanation: This line performs the actual conversion, saving each page of the HTML document as an individual PSD file in the designated output directory.

Troubleshooting Tips:

  • Ensure your output directory exists before running the conversion.
  • Handle exceptions during initialization to prevent runtime errors.

Practical Applications

HTML to PSD conversion can be useful in various scenarios:

  1. Web Design: Transform website layouts into editable PSD files for graphic design software.
  2. Prototyping: Quickly convert HTML prototypes into PSDs for client review or further development.
  3. Content Migration: Facilitate the transfer of web content designs into desktop applications.

Integration with other .NET systems can enhance these use cases, allowing you to embed conversion capabilities directly within larger projects.

Performance Considerations

To ensure optimal performance when using GroupDocs.Conversion:

  • Resource Management: Dispose of streams and objects properly to prevent memory leaks.
  • Efficient Conversion Settings: Tailor the ImageConvertOptions for your specific needs to avoid unnecessary processing.
  • Batch Processing: For large-scale conversions, consider implementing batch processing to manage resource usage effectively.
