- Users of HWGPOST beta 1/2, please note: This text has changed in some places.
- Please read it again.
-
- What is this?
- =============
-
- What you get here is the third version of HWGPOST that is publically
- available. It is _extremely_ raw, very incomplete, and probably buggy as
- hell. My intention is to abuse you as beta tester. ;^)
-
- HWGPOST is project that I started because I had some problems with
- post.library 1.7 (and 1.86 where post.library stayed the same) not handling
- some PostScript code correctly. So I built on the post 1.7 source. HWGPOST
- is IMHO a major step towards PostScript Level 2 already and as time and
- motivation permits it will hopefully become a R&W book compliant PostScript
- Level 2 interpreter library with maybe some Display PostScript extensions.
-
- Currently this archive is probably mostly useful to users of post.library
- up to 1.7.
-
- Major new features for HWGPOST beta 3
- =====================================
-
- - image operators fixed.
- - automatic resource lookup.
-
-
- Requirements & Compatibility
- ============================
-
- OS: >=V37 (= KS2.04)
-
- Memory: As much as possible. HWGPOST tends to need noticeable more memory
- than post.library 1.7 for complex PostScript files. You should have
- at least 2MB to have fun with it.
-
- HD: Suggested
-
- HWGPOST should be compatible to all applications using post.library 1.7
- with the exception of the "callextfunc" and some other special non standard
- operators, e.g. I have found no problems with PostView.
-
-
- Legal stuff/Distribution/bla
- ============================
-
- I need to explain something first. I built on the post 1.7 sources by Adrian
- Aylward. He did an amazing job with post up to and including 1.7. I do not
- claim to having put it all together myself from the the very first byte.
- But I have thrown out or reworked almost every single line of it and there
- is not much left that is truly unchanged. Adrian Aylward set up many useful
- concepts. I reworked most of them for going towards PostScript Level 2.
-
- While it may not look so from the outside, HWGPOST is a major step away from
- its origins, and so I claim the right to have something new here. Note that I
- did not take over any code from other sources than post 1.7 except for
- some fixes to post 1.7 that people sent me (Thanks especially to Tom
- Rokicki for his fixes and other unrelated things). No GNU code, no IBM
- code, nor anything else. To be honest I tried to look at some ghostscript
- code once for a particular feature, but I found it so ugly that I threw it
- out faster than you can say "out" (I never even found the code for the
- feature I was looking for). This means, that all that you read in the
- history file is only my work.
-
- Because of all the above, there will be different rules on HWGPOST that
- start out right _now_ even with this beta version:
-
- - Unlike with post 1.7, I am restricting commercial use somewhat:
-
- For use in commercial products or claims of compatibilty to
- HWGPOST to enhance the value of a commercial product, you need to
- contact me first to work something out.
-
- (Except for Tom Rokicki. He may use HWGPOST whenever he finds it
- acceptable for AmigaTeX)
-
- - If you are just a user of HWGPOST, consider it as Giftware. I like
- money, too, but it doesn't have to be money. Anything nice will do.
- Books, Networking boards, Ax000s, HDs, SW, non technical things,
- whatever. If you intend to use post and forget about me
- intentionally, don't expect any support or bug fixes.
-
- - If you want to use HWGPOST commercially (e.g. to make money by using
- it in your office), I feel that you should consider this very fact
- when thinking about a gift. If you think HWGPOST to be good enough to
- support you making a living, you should value it as such.
-
- - Starting with HWGPOST beta 2, any user of HWGPOST is _required_ to
- register the use of HWGPOST with me via email or smail.
-
- All (important) rights reserved, so to speak. This is currently a private
- undertaking for fun, but I have not yet lost hope that there is maybe some
- reward in it for me, too. :-)
-
- If you don't like the above, I don't want you to use HWGPOST. In fact I
- dare to declare use of HWGPOST then outright illegal. You should live with
- post 1.7 or something else then.
-
-
- Why this beta?
- ==============
-
- A lot of stuff is in place within HWGPOST already even though it is
- probably still far from completion. Actually it is so much that I hope to
- find bugs with your help now. I do not have test cases and PostScript files
- anymore to test all that PostScript Level 2. You will read some "untested"
- comments in the history file. I have checked for basic functionality with
- all my changes, but nobody knows where the bugs hide yet. So I am asking
- you for bug reports to make HWGPOST get better.
-
- I am interested in:
-
- - Enforcer hits, mungwall problems, reproducable crashes
- - deviation of behaviour compared to Adobe Level 2 products
- - Short and precise PostScript example files that break with HWGPOST
-
- and I need your complete computer and OS configuration with any bug report
- including any non C= WB things that you run like
- MagicMenu/ReqTools/CpuBlit.
-
- I am also interested in a short note if you have files using specific
- Level 2 features available with HWGPOST that _don't_ break.
-
- Thank you for your help!
-
- Oh well, if you are one of those using pirated [KS/WB] SW, don't bother
- asking for help. I won't help you and I don't want you to use HWGPOST
- either in this case.
-
-
- What should a bug report look like?
- ===================================
-
- I prefer bug reports created with the C= 'report' tool. Any bug report
- _must_ contain step by step instructions to reproduce the bug on a standard
- WB setup. Telling me "You need to install this pack of special OS hacks to
- make the bug appear" usually leads to no result. If it is a bug related to
- a PostScript program, I'd need a short example program to reproduce it. If
- the bug is dependant on the exact layout of the program (e.g. with eexec
- problems), you should think about using lha and uuencode to preserve any
- spaces, tabs, newlines, or other special characters in the file that might
- otherwise be lost in email.
-
- _AN_ABSOLUTE_MUST_ is the output of C:VERSION FULL (or a version comment in
- the file or printed in a window if C:VERSION does not yield useful
- results) _and_ C:LIST for any program involved. This includes but is not
- limited to:
-
- - The OS (Use ShowConfig)
- - The frontend (post, postband, postview, etc)
- - The library post.library
- - The support files init.ps, HWGPOSTResources
- - For printing, the printer driver
-
- If you don't give me this information with each bug report, I might decline
- to look at it.
-
-
- What is included?
- =================
-
- - README.FIRST (This file)
-
- - post.library (Using C= IEEE libs for all Amigas)
-
- - post.library.20 (Compiled for >=68020 using inline coprocessor math)
-
- - History (Informal overview on the changes since post 1.7)
-
- - init.ps (A new init.ps. You _will_ need to use it)
-
- - HWGPOSTResources (Example declaration of available external
- resources, e.g. fonts. Referenced by init.ps)
-
- - PATH_FONT (Example file to demonstrate automatic font lookup
- by the resource mechanism. This should be copied
- into a directory "ENV:HWGPOST".)
-
- - postlib.h (The include file with some infos on how to use
- the 24 bit color features of HWGPOST)
-
- - post (A hacked up post 1.7 frontend to try out HWGPOST.
- Nothing fancy.)
-
-
- Don't ask me for my sources. Currently I have no plans whatsoever to
- release them in full or part to anyone. After reading through the History
- you might understand why.
-
-
- Special note on the 'post' frontend
- ===================================
-
- The included 'post' frontend is a major hackup of the original (ugly)
- source to suit my testing needs. It may or may not do what you expect and
- it might or might not be compatible to the original 'post'. Anything can
- happen. If you don't get the output you expect, please send me a detailed
- bug report and fall back on PostView or the old 'post' frontend for now.
-
- To get more information on the options try 'post ?' and type another '?' at
- the command line template. For gray scale displays, play with the MAXDEPTH
- option. On an A2024, 'MAXDEPTH=2' and 'DISPLAYID 0x41000' give rather nice
- results compared to the standard B&W.
-
-
- Installation
- ============
-
- 1. Save your existing post.library, init.ps, and post. HWGPOST might break your
- setup and I don't want you to be out in the cold.
-
- 2. I am sure you have the POST: and PSFONTS: assigns that are needed for post 1.7.
- If not. Create them, and put all your type 1 fonts into PSFONTS:
-
- 3. Put init.ps, HWGPOSTResources, and (if you want to) post into POST:
-
- 3.1 Edit HWGPOSTResources for _your_ font setup in PSFONTS: You'll probably
- need to throw out and add some lines.
-
- 3.2 Put PATH_FONT into "ENV:HWGPOST". Edit it to suit your needs. For a
- permanent setup, copy it into ENVARC:HWGPOST, too!
-
- 4. Copy your choice of post.library[.020] into LIBS:
-
- 5. Shut down any running applications using post.library and do an "avail
- flush".
-
- 6. Try HWGPOST and send me detailed bug reports with reproducable examples!
-
-
- My TODO list
- ============
-
- Well, lots of stuff as time permits:
-
- - Composite Fonts (Anybody got a clean one for me as test case?)
- - Finish up Binary Object Sequences
- - User path operators
- - Forms
- - missing filters
- - missing image functionality
- - device parameters
- - insideness operators
- - missing color spaces
- - rest of the Level 2 graphics stuff
- - VM garbage collection
- - whatever else is needed for a languagelevel of 2
