Linux: cmp_tool
Mac OS: cmp_tool

Changelog:

Added

• add -b or --binary option for read and write files in binary format
• add cross compile file for sparc
• add tests for the compression entity
• add test for cmp_rdcu_cfg.c
• add sparc inttypes.h definitions

Changed

• refactor function and constants names
• refactor configure check functions
• move the rdcu setup functions to cmp_rdcu_cfg.c
• update Documentation
• update Doxygen setup

Fixed

• remove memory leaks from tests
• fixed incorrect error message when using rdcu_pkt option without .rdcu_pkt_mode_cfg file
• set the rdcu_par option when using the rdcu_pkt option
• fixed several bug when using the last_info option
• fix a bug in the calculation of the adaptive compression sizes

Executables:

Windows: cmp_tool.exe
Linux: cmp_tool
Mac OS: cmp_tool

Changelog:

Added

• decompression/compression for non-imagette data
• functions to create and configure a compression configuration
• add max_used_bits feature
• add max used bit version field to the compression entity

Changed

• Change the build system form make to meson
• Change DEFAULT_CFG_MODEL and DEFAULT_CFG_DIFF to CMP_DIF_XXX constats

Fixed

• now the adaptive compression size (ap1_cmp_size, ap2_cmp_size) is calculate when the --rdcu_par option is used

Executables:

Windows: cmp_tool.exe Linux: cmp_tool Mac OS: cmp_tool

Changelog:

Added

• Relax the requirements on the input format A whitespace (space (0x20), form feed (0x0c), line feed (0x0a), carriage return (0x0d), horizontal tab (0x09), or vertical tab (0x0b) or several in a sequence are used as separators. If a string contains more than three hexadecimal numeric characters (0123456789abcdefABCDEF) in a row without separators, a separator is added after every second hexadecimal numeric character. Comments after a '#' symbol until the end of the line are ignored. E.g. "# comment\n ABCD 1 2\n34B 12\n" are interpreted as {0xAB, 0xCD, 0x01, 0x02, 0x34, 0x0B, 0x12}.

Changed

• update the header definition according to PLATO-UVIE-PL-UM-0001 Draft 6
  • changed version_id from 16 to 32 bit in the generic header. Add spare bits to the adaptive imagette header and the non-imagette header, so that the compressed data start address is 4 byte-aligned.
• Rename cmp_tool_lib.c to cmp_io.c

NOTE: The behaviour of the cmp_tool has changed. From now on, the compressed data will be preceded by a header by default. The old behaviour can be achieved with the --no_header option.

Executables: Windows: cmp_tool.exe Linux: cmp_tool Mac OS: cmp_tool

Changelog:

• Implement the compression entity header as defined in PLATO-UVIE-PL-UM-0001 for compression and decompression
• small bug fixes

Executables: Windows:cmp_tool.exe Linux: cmp_tool Mac OS: cmp_tool

Changelog:

• added feature to guess the compression configuration
• if samples = 0 the cmp_tool counts the samples in the data file and uses them
• if buffer_length = 0 the 2*samples parameter is used as buffer_length
• some code refactoring
• added more detailed error messages
• small bug fixes

Changelog:

• discard old file format. Now the only input format is like: 12 AB 23 CD .. ..
• change to new compression and decompression library
