@BrandonLee

Hi, thank you for the picture,
I have tried your picture in ImageFx4.5, Photogenics,TVpaint,Ppaint and CandyFactory pro, all have loaded it without any problems.( OK lots of dithering with Ppaint )
I have played about with it in Photogenics and ImageFx.scaled it Colourised it flipped it around and it all works.
In ImageFx it shows it as an 8bit grey file so converted to 24bit (RGB)then to 8bit cmap ILBM, then back to 8bit grey. then reloaded all into Photogenics (V5) which again displayed them with out any problems (all showing as 24bit)

What versions of the software are you using?

I'll have to reinstall Imagine and art effect then I'll have a go with those two as well.
(this is on a Micro A1 with 256MB)

Excuse me, what's your system ?

I have CandyFactory, and works fine in the 1200, but when install the Blizzard PPC stops to work, so I can't installed in the SAM.

But now, I understand that works in youuur OS4.

@ajs

ArtEffect v1.5 and v5

Photogenics5.0

Photogenics1.2 (now stopped working due to missing magazine code!!!!)

ImageFX2.1

GfxLab1.8 (this also CAN'T load the grayscale picture, but since it's an old program, no big deal...)

@broadblues

A bit OT, but... is ImageFX' filename length limitation (max 31 characters) hardcoded inside the program, or it depends on the used loader? If the latter, could it be possible to fix it in your JPEG loader?

This seems worth bumping since we still have people trying to interchange .jpg files in particular between different applications and are having various issues.

Writing a new loader or saver for a program is a limited fix. The following is a global fix:

Download: http://os4depot.net/index.php?function=showfile&file=graphics/edit/jpegoptim.lha
Put jpegoptim in c:

(1)COPY troublesome .jpg files to a new directory.
(2)open a shell and change directory to your new troublesome .jpg directory.
(3)type without quotes "jpegoptim -v -f #?"

You should see verbose feedback on the operation performed on the entire directory.

When completed you should be able to interchange these files with most Amiga applications. The reason we are using a "COPY" instead of the originals, is because you will lose filenotes due this being a port. If that does not matter to you...you can operate on the original files instead.

For those who want to run a test first to prove this, download to RAM:
http://www.reasoft.com/tutorials/web/img/progress.jpg
Try to load it into Adpro for example and it will fail with:
Quote:

unsupported JPEG SOF type

Open a shell, type jpegoptim -f -v RAM:progress.jpg
Now it loads in Adpro.
You'll get similar results with your other favorite apps.

Hmm. We really need to focus more on our advantages, so getting filenote support into ports should be one of the focus points for porters

This weeks pet peeve:
Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C). Sometimes I don't even know what people mean.

True. The same problem exists for our ported file archivers.

The issue with the old programs lies with those using their own custom loaders and savers for the most part. If a program uses datatypes (as Brandon indicated), then you'll be using current loaders and savers and not disturbing either the file headers or the filenotes.

There used to be a program called "Pegger" that intercepted .iff save calls and forced a .jpg save (configurable through Pegger).

Perhaps something like this could be done to address our older s/w. Dunno. But things like this would help all variants of Amiga, so it might be worth trying.

Some info about the concept of Pegger
