Explanation

Code 49 is used to indicate that the content contains images of text.

Images of text are where the text is part of the image data (i.e., it cannot be accessed or read separately by assistive technologies or adjusted to match user preferences). The text could be part of a larger image (e.g., a graph or chart), or it could be the entire image (e.g., stylized headings for which no equivalent font can be provided).

Note that some image formats, like SVG, allow authors to include text in an image that remains accessible to assistive technologies. Use code 45 for this case.

Code 49 is typically set in a <ProductContentType> element for digital publications. Images of text can be prevalent in comics, manga, and similar works, but these are typically characterized as primarily visual works.

Only for use in ONIX 3.0 or later.

Schema.org mapping

Code 49 is the equivalent of setting a visual access mode using schema.org metadata.
