Drizzle and resampling
Spend pixels only when the data supports them.
Forecast drizzle dimensions, working memory and sampling support from frames and dither diversity.
Purpose and method
What this calculator does
Should I use 2× or 3× drizzle? Forecast drizzle output size, memory and sampling support.
In words: Linear dimensions grow by drizzle factor and pixel area grows by its square.
Change a value and the result updates immediately. Adequate sampling is a planning heuristic. Dither distribution, drop shrink, rejection and native optical sampling determine whether drizzle adds real detail.
Working geometry
Dithered sampling grid
Sub-pixel dithers distribute measurements across a finer drizzle output grid.

Governing equation
In words: Output width and height grow by the drizzle factor, so pixel count and memory grow with its square.
