ArmJPEG ⌐ George S. Kapogiannopoulos, 1993
»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»»
!ArmJPEG generates JPEG image files from a various native and foreigner
image formats. It is based on the fourth public release of the Independent
JPEG Group's free JPEG software.
The program in this version ONLY creates JPEG image files because, are
already exist various viewers around.
The reason it was created was to make the life easier for Acorn users who
want to transfer Sprites and AIM files to JPEG image files, who till now,
had to transfer the files to another format (GIF, TARGA, PBMPlus, RLE),
which by the way take no compression, except GIF format which can't handle
24 bit color images. This is why I add and a TIFF extension which can
generate JPEG image files direct from TIFF files (even compressed). The
TIFF format, I think is the best and maybe will be the next Acorn standard,
can handle even JPEG files (revision 6.0) and the source maybe appear to a
next release of the Independent JPEG Group's free JPEG software.
The Program supports the following input image files:
Å Supporting baseline non-planar "II"(little-endian) and "MM"
(big-endian) TIFF revision 5.0 and 6.0, having no compression
or LZW compression TIFF (Tag Image File Format)
Å AIM (Archimedes Image Manager) 256x256 grayscale images
Å Sprites having 256 colours, palette data ignored
The following gives more details about the supporting formats
Filetype Name Commets
&004 * AIM 256x256 grayscale
&ff9 * Sprite only 256 colors, palette data ignored
&ff0 ! TIFF grayscale (Class G)
palette-color (Class C) 8 bpp
RGB full color (Class R) 24 bpp
compression none/LZW for all of the above
&695 ! GIF originally from JPEG Group's software
&69D ! Targa originally from JPEG Group's software
&69E ! PBMPlus originally from JPEG Group's software
&6A1 ! RLE originally from JPEG Group's software
* indicates which image formats are recognized by the filetype.
! indicates which image formats are recognized without having the correct
filetype.
