| chrisl | velix: no | 06:34.42 |
| sine0 | hey folks hows it going. chrisl you around? | 13:57.25 |
| chrisl | I am, yes | 13:57.38 |
| kens | He's here but in the middle of pushing ot a release | 13:57.45 |
| | Ah he even replied, I'm surprised :-) | 13:57.53 |
| chrisl | Doesn't mean I'll *keep* replying ;-) | 13:58.22 |
| sine0 | someone helped me out on stack and gave me some code to create a line drawing/vector image | 13:58.24 |
| | although its using postscript as a language, im not sure, in the most easiest way, how can i make an image like jpg or some file out of this? | 13:58.48 |
| | https://bpa.st/CYHA | 13:58.51 |
| | it has to be command line | 13:59.06 |
| kens | You want to render that program to an image ? | 13:59.14 |
| | Or you want to put an image in the PostScript program and draw it ? | 13:59.26 |
| sine0 | how do i use that code, to make an image, on the command line, easiest as possible | 13:59.39 |
| kens | gs -sDEVICE=png16m -o out.png <file.ps> | 13:59.57 |
| | There are *lots* of devices in Ghostscript which will create image files in various flavours. gs --help will list all the devices | 14:00.43 |
| | I need to step away for 10 minutes, will bbs | 14:00.56 |
| sine0 | wow ok great | 14:01.57 |
| | so ghostscript is an interpreter for vector/print tools? | 14:07.11 |
| chrisl | For Postscript and PDF | 14:07.20 |
| kens | Ghostscript is a PostScript interpreter | 14:07.23 |
| | And as chrisl says can handle PDF too | 14:07.32 |
| | GhostSP handles XPS files | 14:07.41 |
| | and GhostPCL PCL and PXL files | 14:07.48 |
| sine0 | so postscript is a language (I only ever heard of it when fixing the printer drivers on corp network) | 14:07.50 |
| chrisl | Postscript is a fully fledged programming language | 14:08.15 |
| kens | Yep, PostScript is indeed a programming language, this comes as a surprise to many people ! | 14:08.19 |
| sine0 | PDL PCL XPS what are they | 14:08.20 |
| kens | PDL = Page Description Language | 14:08.38 |
| | XPS = Microsoft's more or less failed answer to PDF | 14:08.51 |
| | PCL is HP's printer language | 14:09.03 |
| sine0 | XPS is when you print to file, I know that one | 14:09.04 |
| kens | yeah sort of. | 14:09.18 |
| | Its the native stuff in recent versions of Windows | 14:09.31 |
| sine0 | ok so the language what is it coparible to | 14:09.37 |
| | basic | 14:09.39 |
| kens | Which language XPS ? | 14:09.49 |
| chrisl | Postscript is the only one of those which is a *programming* language | 14:10.10 |
| sine0 | well like that code I showed you it had: EPSF | 14:10.16 |
| kens | EPSF = EPS which ie Encapsulated PostScript | 14:10.34 |
| | Which is a particular subset of PostScript intended to be treated as a 'black box' | 14:10.54 |
| sine0 | using postscript, is it old, is it like BASIC or FORTRAN or soemthing like that | 14:11.05 |
| kens | You can insert it into another PostScript program without knowing anything about what's in it | 14:11.10 |
| Robin_Watts_ | Postscript is not like basic or fortran :) | 14:11.15 |
| kens | PostScript is not quite as old as BASIC or Fortran | 14:11.22 |
| Robin_Watts_ | Except in that it's interpreted. | 14:11.29 |
| kens | But it is old, 1980s | 14:11.32 |
| Robin_Watts_ | It's more akin to lisp in some regards, but even that is not really fair comparison. | 14:11.59 |
| velix | dang dang dang | 18:43.19 |
| | Seems like Cairo 1.16 already fixed my PDF problems. | 18:43.30 |
| | 1.12 <-- error | 18:43.36 |
| | 1.16 <-- no error, GS can display the file | 18:43.45 |
