Detailed Description

Reads simple text comment metadata from image files.

CommentMetadata extracts basic comment fields that some image formats support. This is the simplest form of metadata, typically just a single text string describing or annotating the image.

JPEG comment segments and similar simple metadata formats are handled by this class. Unlike EXIF, XMP, or IPTC, comments don't have structured fields.

Usage:

FileInputStream stream(imageFile);
OwnedArray<ImageMetadata> metadata;
ImageMetadata::getFromImage(stream, metadata);
 
for (auto* meta : metadata)
{
    if (auto* comment = dynamic_cast<CommentMetadata*>(meta))
    {
        StringPairArray data = comment->getAllMetadata();
        String commentText = data["Comment"];
    }
}
