- Special notes for CJPEG_ST.TTP / DJPEG_ST.TTP
-
-
- This Version (V3A) of the IJG's JPEG SOFTWARE has been subject to several
- Atari - dependent changes :
-
- - Compiled with Turbo-C (smaller and faster executeables)
-
- - Memory manadgement :
- + by default, all availeable memory is beeing used
- [ free memory is determined by coreleft() now]
- + swap-files : if the enviroment variable TMP or TEMP points to a valid
- directory, temporary files are put there instead of the working directory.
-
- - Commandline / Desktop usage:
- + though cjpeg/djpeg use TWO_FILE_COOMADLINE (this means you have to name
- both input -and outputfile in the commandline - see file USAGE),
- you can use them with your desktop as an "installed application" :
- + If djpeg only gets one filename (the .jpg file), it produces a .gif
- file of the same name (djpeg foo.jpg produces foo.gif) as output.
- Cjpeg : almost the same. Parameter is the name of the source file,
- a .jpg file with the same name is produced.
-
- - progress monitor :
- + completion is displayed in percent.
-
- - speed :
- avarage decoding / encoding time is 3 - 5 minutes.
- (djpeg takes a lot of time for 2-phase-quantization - see USAGE)
