Changelog

v0.7.0 - 2026-08-19

Features

• Limit OpenCV, BLAS and OpenMP operations to single threads inside Python pool threads to reduce contention.

• Allow for source and ortho images with dimensions greater than 32767 (#26).

• Improve pan-sharpening performance with an increased block size that results in multi-threaded WarpedVRT reads.

• Add a ztd compression option.

• Add an --aligned-pixels CLI option, and aligned_pixels Ortho.process() parameter to align ortho pixels so their world coordinates are multiples of the resolution.

Fixes

• Fix Camera.pixel_boundary() returning an incorrect number of points for some image size / num_pts combinations.

Packaging

• Limit the OpenCV dependency version to <5 to avoid https://github.com/opencv/opencv/issues/29412.
