Pushing Photoshop CS2 to its limits with ActionScript

Question

I'm using Photoshop CS2 with Windows XP (lastest SP) and a Core2 4 Gb RAM PC.
Here's what I did :
I developped a javascript file for photoshop that opens another (pretty huge) file and reads it line by line and executes line by line.
This helped me to execute a huge javascript stuff.
This javascript stuff... generates one of the biggest (if not the biggest) maze in the world.
But.
Photoshop "agrees" to create a big file.
Photoshop "agrees" to draw in it for a lot of times.
Each 20 draws, Photoshop "agrees" to empy ALL the history (i think this would help to free RAM or whatever).
After say 80 % of the stuff done, there's an error that pops up.
This is not a javascript problem, I swear I've been looking for it for months now.
My generated javascript file is okay.
You can download the whole stuff here, uncompress it into the Photoshop script folder (usually "C:\Program Files\Adobe\Adobe Photoshop CS2\Paramètres prédéfinis\Scripts") and launch it (via "File=>Scripts=>m")
What I don't get is :
- if Photoshop "agrees" to create a big file.
- if Photoshop "agrees" to draw in it for a lot of times.
- if each 20 draws, Photoshop "agrees" to empy ALL the history (i think this may help to get RAM)
why on earth does it stop with a problem that seems to have nothing to do with memory allocation (but it has actually : I've just generated more than 1500 scripts and each time I made the script bigger and launched it : it worked without any problem at all so this is not a problem from my script (I've generated (with my own C program) a BMP file based on that javascript file and it generated the maze properly)).
I'm pretty convinced this is a problem with Photoshop, and only Photoshop.
Another problem I had to face that is documented nowhere, even in the JavaScript help file, (I told you I pushed Photoshop to its limits ) is that you are limited to 999 points when you create a path in JavaScript. Why is that ? This is not normal. So I had to modify my entire Javascript program to make it work properly. It has to create paths with 999 pixels, then draw them, clear the path, and son on.
Please tell me if my script works either with CS4 and / or with Windows Vista.
My goal is to create something like 15000 x 15000 pixels files (I'm not joking).
I was counting on Photoshop to use its own swap file and help me to generate mazes bigger than the ones my C program generates. But it can't for now.
Any help is greatly appreciated.

Answer 1

Here's what I've just tried : a vbs file that launches photoshop CS2, then executes action "M1" then action "M2"
Action "M1" executes the JavaScript "M1"
Action "M2" executes the JavaScript "M2"
The JavaScript M1 executes 998000 lines
The JavaScript M1 executes 1000 lines then stops.
So in essences I should have to :
(1) launch "M1" that creates the image and then executes 998000 lines
(2) save the image
(3) quit photoshop
(4) re-launch photoshop
(5) re-load the previously saved image
(6) launch "M2" that creates the image and then executes 998000 lines
I'll try that tonight.
This is far from being easy and nice. I hate when we need hacks to make simple things work
Anyway here's the source codeto launch Photoshop then the ActionScript M1 then the ActionScript M2 (if it is of any use) :
REM =======================================================
DIM objApp
SET objApp = CreateObject("Photoshop.Application")
REM Use dialog mode 3 for show no dialogs
DIM dialogMode
dialogMode = 3
DIM id1
DIM id2
DIM id3
DIM id4
DIM desc1
DIM ref1
id1 = objApp.CharIDToTypeID( "Ply " )
SET desc1 = CreateObject( "Photoshop.ActionDescriptor" )
id2 = objApp.CharIDToTypeID( "null" )
SET ref1 = CreateObject( "Photoshop.ActionReference" )
id3 = objApp.CharIDToTypeID( "Actn" )
Call ref1.PutName( id3, "M1" )
id4 = objApp.CharIDToTypeID( "ASet" )
Call ref1.PutName( id4, "Olivier" )
Call desc1.PutReference( id2, ref1 )
Call objApp.ExecuteAction( id1, desc1, dialogMode )
id1 = objApp.CharIDToTypeID( "Ply " )
SET desc1 = CreateObject( "Photoshop.ActionDescriptor" )
id2 = objApp.CharIDToTypeID( "null" )
SET ref1 = CreateObject( "Photoshop.ActionReference" )
id3 = objApp.CharIDToTypeID( "Actn" )
Call ref1.PutName( id3, "M2" )
id4 = objApp.CharIDToTypeID( "ASet" )
Call ref1.PutName( id4, "Olivier" )
Call desc1.PutReference( id2, ref1 )
Call objApp.ExecuteAction( id1, desc1, dialogMode )
