All notable changes to this project will be documented in this file.
- Fixed two bugs that prevented intensity limits from being read correctly.
- Made color and intensity normalization optional (still enabled by default).
- Better intensity and color normalization using the proper limits of the point cloud. The library was using the type ranges before, which is now only a fallback.
- Allow setting intensity and color limits manually when writing point clouds.
- Improved documentation related to color and intensity topics.
- Fixed reader bug that occured for some cases when a point cloud contained values where min=max. See issue #12 for more details: #12
- Added some convenience helpers for getting Cartesian bounds.
- Some very minor documentation improvements.
- Fixed critical writer bug that occurred when the compressed vector section header and the data offset were not in the same page. In such cases the the data offset was off by the 4 bytes, (which is the size of the CRC32 checksum).
- Fixed potential alignment bug in writer when doing early outs while writings points to disk.
- Updated example code to use the latest version of the LAS crate.
- Fixed critical writer bug that could produce invalid E57 files. This occured when point attributes sizes were not full bytes, for example intensity integer values between 0 and 2047. In other cases the file was valid, but contained wrong values for such attributes.
- Fixed minor corner case in reader when a data packet did not contain a full point.
- This version was yanked from crates.io and is no longer available!
- Broken fix for critical writer bug that could produce corrupt E57 files.
- Updated
roxmltreedependency to version 0.20.
- Fixed typo in
intensityMaximumXML tag when writing E57 files. - Added missing support for non-integer color and intensity limits when writing E57 files.
- Breaking Change: Fixed typo in public API to register E57 extensions.
- Fixed reading E57 files without data3D or images2D tags in XML section.
- Added public API to write and read arbitrary blobs for E57 extensions.
- Added public API to allow XML customization for E57 extensions.
- Extended documentation and example code for E57 extensions.
- New flag for e57-unpack tool to extract only images and skip point data (thx Graham!)
- Fixed handling of integer values when min and max values are equal.
- Very minor documentation improvements.
- Enabled and fixed additional Clippy lints.
- Deleted some unused code from paged reader.
- Smaller perfomance improvements for reading E57 files.
- Fixed paged writer boundary crossing errors (thx nil-vr!)
- Fixed alignment issues after writing image blob sections (thx nil-vr!)
- Updated
roxmltreedependency to 0.19, which removes the indirect dependency toxmlparser. - Fixed handling of integers and scaled integer values without explicit min and max values.
- Fixed handling of big integer and scaled integer values (avoid i64 overflows).
- Allow bigger integer ranges in the simpler iterator for invalid state values.
- Make simple iterator more robust against weird color and intensity values. It will now use zero values as fall back in case a value cannot be mapped to a unit float.
- Fixed bug when converting Cartesian to spherical coordinates.
The code used
atan2(x, y)instead ofatan2(y, x)which flipped the data horizontally. This problem was not detected since the unit tests were too simple. They have now been extended to capture this issue.
- Added missing support for original GUIDs member of point clouds. The breaking API changes for this feature were already part of the last release.
- Allow access to the E57 library version field when reading E57 files.
- Breaking Change: Made GUIDs for point clouds and images optional. This required changes in the corresponding public structs. The spec says the GUID for both is required, but the C++ implementation allows to omit it. Some software (e.g. Matterport) is generating files without them, so we need to make it optional to stay compatible and read these files. When creating E57 files, the library still enforces setting the GUIDs.
- Breaking Change: Prepared structs for missing original GUIDs. This feature was missing and was prepared now to avoid more breaking changes later. Its not yet implemented and can be added later as non-breaking change.
- Fixed major bug that prevented adding images to E57 files. Some required property structs were accidentally private.
- Added some C++ utility code to generate test example files using the libE57format library.
- Restructured and extended integration tests to cover more cases.
- Breaking Fix: Added missing implementation for offset in scaled integers. This required changes in the basic enum for record data types.
- Additional perfomance improvements when reading E57 files.
- Added validation for XML namespaces and attributes when writing E57 files with extensions.
- Added support for optional faster external CRC32 crate.
- Implemented optional size_hint() for reading point cloud iterators.
- Reworked image extraction tool to become a generic E57 unpack tool.
- Very minor improvements to the XYZ-to-E57 tool.
- Breaking: Reworked simple iterator to make it easier to use
- Breaking: Removed simple iterator option to skip invalid points
