Description

The current writer API operates on full images. This causes problems when trying to save images that are larger than the amount of memory allocated to the JVM; in addition, images with more than 2 GB of pixel data cannot be saved, regardless of how much memory is allocated.

Ideally, the writer API would be updated to be tile-based (much like the reader API). Then large images could be split up into more manageable tiles, and each tile could be saved separately.

(In [6294]) Added API for tiled image and multi-file export (see #413 and #486). There are several known issues (see Export), but basic export should work.

  • Status changed from new to closed

Closing, as the API and several implementations are in place as of r6508. There are still several known issues with this feature; see this page for a list.
