For example, the text layer is typically stored at 300 or 400 dots
per inch resolution in one-bit binary (black and white) color
depth. This enables you to index the document for full search and
retrieval. It also enables you to OCR the document so you can use
the actual text in your word processor or other application.
The photographs and other pictures in the document are stored as
24-bit color segments typically in 75–200 dots per inch
resolution. This enables you, for example, to copy and edit a
photograph from a scanned document in your graphics editing
software. It also enables an recognized document in your word
processor to include the color pictures from the original document.
The background tint and text color layers are present so that
if you print a document, the output remains true to the original.
