ReadMeDocs/JPEG_Fix
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
JPEG_Fix ======== This file documents how to make changes to ChangeFSI so that it can recognise and handle "progressive JPEG" images. The instructions are adapted from my posting on comp.sys.acorn.apps & comp.sys.acorn.misc in the middle of October 1996. Contents: Patching ChangeFSI Installing the new JPEG software And Finally ... Technical Notes Patching ChangeFSI ================== Making sure you start with version 1.15 (although it may work for other versions too), load !ChangeFSI.ChangeFSI into your favourite BASIC editor (keeping a backup copy!) and make the following changes: Find the line which says the following (If you search for the string "JFIF" it's a couple of lines below it) IFcache%<EXT#c% THEN Change this to say: IFcache%<EXT#c% OR ASCMID$(S$,12,1)>1 OR FNsnb_needdjpeg(c%) THEN (DON'T have any trailing spaces on the line or it won't work!) Add at the end of the program: DEFFNsnb_next(c%) LOCALv%:WHILEBGET#c%<>255 AND NOTEOF#c%:ENDWHILE:IFEOF#c%:=&100 REPEAT:v%=BGET#c%:UNTILEOF#c% OR v%<>255:IF EOF#c%:v%=256 =v% DEFPROCsnb_skip(c%) LOCALv%,w%:v%=PTR#c%:w%=BGET#c%:w%=(w%*256+BGET#c%) PTR#c%=v%+w%:ENDPROC DEFFNsnb_needdjpeg(c%) LOCALsz%:REM Not Acorn code - added. Assumes file is JPEG! PTR#c%=2:REPEAT:sz%=FNsnb_next(c%):IFsz%=&C0 OR sz%>255:=FALSE IFsz%>&C0 ANDsz%<&D0 ANDsz%<>&C4 ANDsz%<>&CC:=TRUE:REM M_SOFn IFsz%>&E0 AND sz%<&F0:=TRUE: REM M_APPn PROCsnb_skip(c%):UNTILEOF#c%:=FALSE Save this, keeping a backup of the original. That completes the changes to the ChangeFSI program itself. Now you need to install the new JPEG software. Installing the new JPEG software ================================ Open the "djpeg" directory which was in the root of the ArcWeb archive and copy the djpeg program that you find inside to somewhere on Run$Path so that ChangeFSI can see it. (You may choose to copy it into the !ChangeFSI directory itself (or !ChangeFSI.djpeg directory) And Finally ... =============== That should do it - it now works for me. The following text is a description of how it works and reading & understanding of it is not necessary :-) Technical Notes =============== This change allows ChangeFSI to spot non-baseline JPEGs and farms that out to djpeg. Note that even djpeg doesn't handle some of the arithmetic encodings, but it does allow it to handle images that it otherwise can't. Note that all my new functions are prefixed "snb_" to avoid name clashes. Non-JFIF files are trapped here too since anything with a filetype of &C85 is accepted as JPEG. If ChangeFSI is ever extended to supported more SOFn markers, then these can simply be trapped within the REPEAT loop and return FALSE for those SOFn types. -- Stewart Brodie 17th October 1996
