A good Amiga PDF reader
Does anyone know of a good pdf viewer for the Amiga? I am currently using apdf, but it seems to have problems with many of the pdf files. I am currently running amigaos 3.9.
Thanks |
Apdf sucks as it supports a very old subset of the PDF format, which means you wont be able to see most of your pdf files.
You should install GhostScript 8.70 and use as a front end either gsgui or easygs. It is a pain to install and get GhostScript running, but it is worth the trouble. |
Is it a problem with installing ghost script 8.7 when ghostscript 4 is installed with turboprint. Do I need to remove The version that came with turboprint And replace it with 8.7? Doi keep both versions installed? Thanks
|
Somewhere on the GhostScript 8.70 website there is a tip on getting it to work properly with Turboprint, I cant emember right now how it was, but it worked.
|
Does somebody know from where GostScript 8.70 and EasyGS for 68k can be downlaoded nowadays?
As I see it in Aminet is only the MorphOS version of GhostScript 8.70. |

Thank you :great
And any idea from where to get EasyGS? Couldn't somebody be so kind and put it into the zone? |
So yesterday I tried the GhostScript 8.70 package for pdf rendering. I was using the gs command for rendering. And it went well..but I was a bit baffled how slow it was.
On an emulated 68040 (as fast as possible but no JIT, SysInfo states it as 1.8 x as fast as an A4000/25) I could see how a pdf was "painted" line by line. It took e.g. forty seconds to display one page. I tried different pdfs, always the same. I'm just wondering, because on the same system displaying some jpeg images using PicShow didn't take nearly as long. So is there any known speed-up option in GhostScript? |
Lower dpi value speeds up a bit. b/w is faster then grey then color then more colors. ;) Generally higher quality = lower speed. The documentation is good, so have at least a read here: http://www.whoosh777.com/index.php?txt=1#usage

Thank you, I'll try that out.
|
If you have an RTG setup, I'd suggest to try the RNOPDF program. It's a simple but quick PDF viewer, and is available for 68k, 68k+FPU, WarpOS, and several other platforms.
|
Also RNOPDF does not support many PDF formats.
It would be nice to have on Amiga "PDF-XChange Viewer" a free, small, light and powerful viewer. |
If you don't need the ability to search there are tools to render very fast into bitmap gfx files
I haven't used this myself but it is the most recent on Aminet http://aminet.net/text/misc/xpdftools_400_m68k.lha And if your Amiga is connected to the internet you can of course use a free online PDF->TIFF converter which usually give you the PDF back as a zip containing a TIFF for each page. |

EDIT: I have to repeat the tests in my system was missing the Holliwood library "polybios.ext" now always open many more PDF documents. |

there are still some "simple" PDF files that are not supported, although RNOPDF supports even complex PDF files. The only problem is the Zoom that does not work well. it does not maintain the status |

Also, is there any particular reason you're not using JIT? Some games don't like it due to their funky coding tricks, but then they're less likely to run on a 68040 anyway. If you're emulating a top-end Amiga, turn on JIT and enjoy the massive speed boost it gives you. Ultimately, rendering PDFs, like rendering web pages, is as simple or as complicated as the document itself is. That means there's nothing to stop a very complicated document taking a huge amount of processing power to render, power which is taken for granted on modern platforms. Reducing the render quality/accuracy will help, but ultimately there's no getting away from the fact that there's a lot of computation involved. |

Ah, I take it the debugger is using some sort of funky tricks then. Well it might be worth trying it as an emulated 68020 with JIT instead. The simpler CPU has fewer pitfalls for exotic code, and speed should get a massive boost. Ultimately, rendering PDFs in a non-JIT environment is simply pouring away CPU cycles, so if it still doesn't work I'd suggest using the host OS to open PDFs, maybe using a second display.
