Thank you for the PR! That's an exciting speedup! I have two requests:
- Please sign off the commits (
git rebase --signoff) so the DCO check passes - Please fix the 7 test failures https://build.ros2.org/job/Rpr__rosidl_runtime_py__ubuntu_noble_amd64/4/testReport/
rosidl_runtime_py/convert.py

Please keep this argument name as truncate_length. This appears to be the cause of some of the test failures.

The `_convert_value` function takes a lot of time converting array types, especially making conversion of image types very slow. This change accelerates this conversion when the complete images are handled (`no_arr` option is off, no truncation applied). Signed-off-by: Zoltan Beck <zoltan.beck@woven.toyota>

The
_convert_valuefunction takes a lot of time converting array types, especially making conversion of image types very slow. This change accelerates this conversion when the complete images are handled (no_arroption is off, no truncation applied).Example for speedup:
The conversion time went down for a compressed image of 256 bytes more than 10 folds, with possibly higher gains at reasonable image sizes.
