Porting Photoshop to Amiga

KONEY · 20 December 2016, 15:04

Semi serious proposal: porting Photoshop 1.0 to classic Amigas, starting from its source code available here: https://github.com/amix/photoshop

After reading this http://computerhistory.org/atchm/ado...p-source-code/ I've been asking myself how doable a porting would be but having no Amiga coding skills I never manage to give me an answer, hence this post :=

"about 128,000 lines of mostly uncommented but well-structured code. By line count, about 75% of the code is in Pascal, about 15% is in 68000 assembler language, and the rest is data of various sorts."

This makes about 20.000 lines of undocumented assembler code. It would need months, maybe years.

...but well-structured

Who needs Photoshop? We have Dpaint!

nobody · 20 December 2016, 16:00

I guess Photoshop is a different thing than dpaint. Photoshop does more things, dpaint is a pixel manipulation program.

KONEY · 20 December 2016, 16:06

it was a joke I think

Anyway better speak of Personal Paint, ages ahead of Dpaint

I would have thought Photogenics would have been closer to Photoshop on the Amiga if I recall.

Solo Kazuki · 20 December 2016, 18:47

And ImageFX.

jPV · 20 December 2016, 19:26

And FxPaint and ArtEffect... etc...

ArtEffect is my favourite of this kind of painting (non pixelling) programs. I'll still use it all the time for more modern painting needs (retouching of scanned images, creating alpha transparencies, extensive magic wand usage etc).

In any case I think all these newer major gfx packages on Amiga should make Photoshop 1.0 obsolete

nogginthenog · 20 December 2016, 19:26

And GIMP. Needs X-Windows though...

There are talks somewhere of a indea for a compatibility layer for Mac OS classic applications structured in the same way Wine is structured in linux; that would indeed help run mac binaries but i don't see it as a short time commitment - btw a thing like that cannot be called other than "hard cider"

Perhaps the most successful was "TVPaint", HERE on one of my old review there are many others

You can use photoshop 4 on amiga apparently.

Version 4 has support for layers which is pretty handy.

saimon69 · 20 December 2016, 23:38

I would say with emulation 3.0.5 or 4 do a good job, however 3.0.5. is lighter; has layers but lack macros and batch conversions that instead 4 has. however the shareware GraphicConverter can substitute on that.

The original topic was, however, to get the source of PS1 and compile it for Amiga natively.

there is no need to port photoshop to the Amiga
you can use it right now in MACOS emulation using shapeshifter or fusion

the last 68k version is photoshop 4.0 you can download it here

Damn, now you spoiled people here of the fun of going through 20000 lines of "well structured" assembler code.

JimDrew · 29 December 2016, 05:35

That's not many lines of code to go through. PCx is 1.6 million lines of assembly code, not including the drivers.

Devlin · 29 December 2016, 16:53

I'd be down for a re-sourced version of photoshop for the amiga provided it stays light on requirements (no mui/ixemul etc etc cos fuck that noise)

idrougge · 29 December 2016, 20:17

Why would anyone want to run Photoshop when you have ArtEffect?

That doesn't look like it's free, and porting Photoshop is likely to be a labour of love for the porting team more than anything.

At least if someone does take on the task of porting Photoshop, we'll be able to say it's native on our amigas now
