IPTC Information

IPTC (International Press Telecommunications Council) information refers to a standard used for embedding metadata within image files. This metadata typically includes information such as the title, description, keywords, copyright information, and other details relevant to the image.

IPTC information allows photographers, journalists, and other content creators to embed descriptive and administrative metadata directly into image files. This metadata can then be used by various software applications for organization, search, and retrieval purposes.

Some common IPTC metadata fields include:

  1. Title: The title or headline of the image.

  2. Description: A brief description or caption of the image.

  3. Keywords: Keywords or tags associated with the image, aiding in search and categorization.

  4. Creator: The name of the photographer or creator of the image.

  5. Copyright: Copyright information and usage rights for the image.

  6. Date: The date the image was created or captured.

  7. Location: The geographical location where the image was captured, if applicable.

  8. Usage Terms: Any specific terms or restrictions regarding the usage of the image.

IPTC information is commonly used in various fields such as journalism, photography, publishing, and digital asset management to provide context and organization to image files. It helps streamline workflows, enhance searchability, and ensure proper attribution and rights management for images.

async function extractIptcMetadata(imageBlob) {
  // Use a library or built-in functionality to extract IPTC metadata
  // For example, you can use exifr library
  const metadata = await exifr.parse(imageBlob);
  return metadata.iptc;
}

  // Format metadata in HTML format
  let html = '<html><head><title>Image IPTC Metadata</title></head><body>';

    html += `<li><strong>${key}:</strong> ${value}</li>`;
  }
