Orientation-normalized RGBA; may be a reduced-resolution preview.
Original canonical dimensions, used to scale coordinates into the decoded buffer.
Same fit used for preview and final export.
Coordinate system in which the fit operates.
Validated output from outputGrid; this function allocates width × height × 4 bytes.
Interpolation kernel.
Host projection definitions.
Optionalprogress: (v: number) => void
Synchronous progress fractions, reported every 32 rows and at completion.
Newly allocated raster; the input is not mutated.
Synchronously backward-map output pixel centres through the fit and resample the source. Use the worker engine for interactive applications.
