Watermarks Augmentation (e.g., “COPY” / “VOID” / “DRAFT”)

[jboarman]

Document-oriented watermarks are common and have several patterns that we can attempt to reproduce:

• large print overlaid on document, of varying fonts and weights
• printed often at angles, diagonal across the page, from bottom-left to upper-right corners (at least in the US); or it can simply be horizontally placed on the page
• sometimes makes document text illegible, but most often watermarks are lightweight to allow readability of original document
• sometimes the watermark is laid over the text, and sometimes it's under the text
• dithering (20% probability) or some level of alpha blending (75% prob) is common, if not solid (5% prob)
• common watermark phrases: COPY, VOID, DRAFT, CONFIDENTIAL, UNOFFICIAL, DO NOT COPY, SAMPLE, ORIGINAL
• text is usually in UPPERCASE, but sometimes Title Case, or lowercase
• watermark may be some degree of grey (85% probability), red (10% prob) or any random color (5% prob)
• sometimes has border (like it was a stamp) or partial border (just lines at top and bottom of text) (5% prob, each)
• the same logic applied using smaller "watermarks" at more varied angles could suffice to double this augmentation as a "stamps" augmentation

Other kinds of Watermarks (Not in Scope)

These other kinds of watermarks most associated with stock photos, or premium paper / historical documents when held up to a light source, is NOT part of the scope of this ticket, at least not initially.
