Short: New Datatype for JPEG Images (43.6) Author: achimste@gmx.de (Achim Stegemann) Uploader: achimste@gmx.de (Achim Stegemann) Version: 43.6 Type: util/dtype Requires minimum: * OS 3.0 * MC68020 Additionally recommended: * CyberGraphX with picture.datatype V43 for 24-bit images. * MUI 3.8 for the preferences. If you run OS 3.5 or OS 3.9, it is recommended to install the JPEG-DT35 archive !! With the help of the jpeg.datatype, your datatype sytem is able to read JPEG images. This datatype is freeware and can be used for any purpose ! ##### Why another datatype for JPEG images ? ##### Well there are many of them available on the Aminet, but this has two unbeatable advantages !! 1. It is very short, only about 8 kB !! Why ? Because it does not contain the JPEG de/encoder and color quantizer in the datatype itself. The datatype uses the jpeg.library from Paul Huxham for the JPEG de/encoding and the render.library by Tim Müller for color reduction. The jpeg.library has been developed from the latest JPEG V6b release, so it is up-to-date. 2. It can write JPEG files when using the DTMW_RAW flag in the DTM_WRITE method !! The V45 of datatypes by Roland Mainz is supported, so you can convert any datatype picture to JPEG. #### Note #### If you have another jpeg.datatype (with THIS name) installed on your Amiga with a version number higher than 43.0, the installer will not be able to replace it. In this case, you must copy the jpeg.datatype manually to your SYS:Classes/DataTypes directory. Changes since V43.5: * Cleaned up ramlib-stuff (thx to Oliver Roberts). jpeg.library (WarpOS version) works again with datatype, no crashed with IPrefs :) ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 3435 2482 27.7% 06-Jul-01 01:37:52 JPEG-DT.info 11396 5677 50.1% 18-Jul-01 12:49:44 +jpeg.datatype 98 82 16.3% 06-Jul-01 01:37:46 +JPEG 12 12 0.0% 06-Jul-01 01:37:46 +jpeg.prefs 2200 562 74.4% 18-Jul-01 12:44:02 +Install 4232 2886 31.8% 10-Jul-01 12:22:06 +Install.info 3974 1921 51.6% 18-Jul-01 12:47:08 +JPEG-DT.doc 3576 1924 46.1% 06-Jul-01 01:37:46 +JPEG-DT.doc.info 1692 929 45.0% 18-Jul-01 12:47:24 +JPEG-DT.readme 2221 1385 37.6% 06-Jul-01 01:37:46 +JPEG-DT.readme.info 79480 45414 42.8% 06-Jul-01 01:37:46 +jpeg.library_020881 85780 48582 43.3% 06-Jul-01 01:37:46 +jpeg.library_020std 78108 44782 42.6% 06-Jul-01 01:37:46 +jpeg.library_040881 84156 47741 43.2% 06-Jul-01 01:37:46 +jpeg.library_040std 77808 44712 42.5% 06-Jul-01 01:37:46 +jpeg.library_060881 84104 47841 43.1% 06-Jul-01 01:37:46 +jpeg.library_060std 119160 52071 56.3% 06-Jul-01 01:37:46 +jpeg.library_wos 52452 23487 55.2% 06-Jul-01 01:37:46 +render.library 52244 23390 55.2% 06-Jul-01 01:37:46 +render.library_68040 52436 23362 55.4% 06-Jul-01 01:37:46 +render.library_68060 8741 6048 30.8% 06-Jul-01 01:37:46 +Prefs.info 10024 4878 51.3% 18-Jul-01 12:49:44 +JPEGPrefs 3902 2924 25.0% 06-Jul-01 01:37:46 +JPEGPrefs.info 87 77 11.4% 18-Jul-01 12:49:44 +class.h 12228 3680 69.9% 18-Jul-01 12:49:44 +dispatcher.c 67 67 0.0% 18-Jul-01 12:49:44 +jpeg.fd 1969 635 67.7% 18-Jul-01 12:49:44 +jpeg.¶ 7683 2120 72.4% 18-Jul-01 12:49:44 +jpegprefs.c 1278 483 62.2% 18-Jul-01 12:49:44 +jpegprefs.¶ 281 207 26.3% 18-Jul-01 12:49:44 +jpeg_lib.h 2370 808 65.9% 18-Jul-01 12:49:44 +libbase.c 3101 1194 61.4% 18-Jul-01 12:49:44 +savejpeg.c -------- ------- ----- --------- -------- 850295 442363 47.9% 27-Jul-101 01:01:12 32 files
