- HAMSHARP 1.4

-
- This Amiga program converts GIF files to IFF files (using HAM if required).
- It takes a while to run (typically 3 minutes) but produces HAM images with
- few colour errors. It is also useful for showing full PAL pictures when
- used in conjunction with PAL-capable IFF viewers.
-
- It is invoked from the CLI with the following command:
-
- hamsharp [source_file] [destination_file] [options]
-
- MS-DOS style wildcards (*) are allowed in the source and destination
- filenames. The options are:
-
- -b# Disk buffer size (# ranges from 1 to 32767, default 16384).
- -c IFF Compression off.
- -d Distribute colours. Try this for some digitized pictures etc.
- -e Edge enhancement. Try this for diagrams and ray-traced pictures etc.
- The -d and -e options are opposites. Default is -e.
- -f Fix filenote indicating image error.
- -h HAM-only conversions. Skip non-HAM files.
- -s# Line step size. Use with -e option only.
- (# ranges from 1 to 4. Default is 2. Larger values gives faster
- processing at the expense of accuracy).
- -u Update. Skip files whose destination already exists.
-
- To stop the program at any time, press ctrl-C <return>.
-
- Examples
- --------
- hamsharp src.gif dst.iff
- Converts a single file.
-
- hamsharp df1:*.gif *.iff -b32000 -h -s4
- Converts a batch of HAM files quickly from drive 1 to the current
- directory.
-
- hamsharp src.gif dst.gif -d
- Converts a file using the alternative algorithm.
-
- Changes from 1.0 to 1.2
- -----------------------
- - Fixed minor bug in header of non-HAM IFF files.
- - Fixed bug allowing IFF files with an odd number of bytes.
- - Implemented batch mode facility.
- - Implemented -h option to skip non-HAM files.
-
- Changes from 1.2 to 1.3
- -----------------------
- - Fixed incorrect body length parameter in IFF files larger than 64K.
- - Added buffering for faster writing to floppies.
- - Implemented -c no IFF compression option.
- - Implemented -f filenote option.
- - Implemented -u update option for resuming interrupted conversions.
- - Incorporated HAMMER into HAMSHARP. Use -d/-e options to select algorithm.
-
- Changes from 1.3 to 1.4
- -----------------------
- - Slightly improved algorithm results better pictures.
-
- Changes from 1.4 to 1.5
- -----------------------
- - Slightly reduced memory requirements.
