Discover how font size impacts digital and print media quality. The Apryse Server SDK streamlines secure document process By definition **1 point = 1/72 of an inch**, and a resolution of 72 dots per inch on paper (or pixels per inch in the context of digital media) implies that 1 dot (or 1 pixel) = 1 point. Roughly speaking, to have a 12 point font means that glyphs are bounded by boxes of 12 points in height maximum (as in older days they would have been cut in 12 point tall blocks of wood), so that at 300 PPI 12-point-font glyphs would be inscribed within 50x50 pixel bounding boxes. A good rule of thumb is that more pixels in a glyph is better than less, OCR quality starts to diminish exponentially if glyph bounding boxes get smaller than 20x20 pixel. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.apryse.com/core/ocr/resolution.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
