| ghostbot | Welcome to #ghostscript, the channel for Ghostscript and MuPDF. If you have a question, please ask it, don't ask to ask it. Do be prepared to wait for a reply as devs will check the logs and reply when they come on line. | 03:52.48 |
| DrChalisque | Hi, I'm a newbie to irc, freenode and thus this channel also. I have long held a fascination about postscript, have fond memories of writing pure ps programs in the late 90s and am at a point in life where I have the time to sit down and do a bit of learning. | 12:16.08 |
| | I'd like to learn my way around the basic bits of postscript, with ghostscript as a reference. I am thinking of reading the source of historical versions, since presumably they will have little beyond the core facilities implemented, making the haystack smaller. | 12:17.06 |
| Robin_Watts | Really, learning postscript is NOT best done by reading the gs source. | 12:42.36 |
| DrChalisque | I am interested in learning how the implementation of postscript works (i.e. how one renders a letter of a type 1 font). I want to learn how ghostscript works, not how to write postscript code. I did that years ago. | 12:55.54 |
| | E.g. how does gs turn '100 100 moveto (Hello World) show' into actual text | 12:56.58 |
| Robin_Watts | Well, in the case of gs, stuff is broken down into a series of 'device' calls. | 13:18.56 |
| | where devices know how to do things like draw a line, draw a character etc. | 13:19.19 |
| | Different devices can implement these calls in different ways. | 13:19.36 |
| | For instance, the pdfoutput device will keep 'draw a char' as a high level thing (characters stay as characters) | 13:19.56 |
| | but other devices, like raster output, might break 'draw a char' down into 'draw a path', which in turn gets broken down into 'draw these pixels'. | 13:20.36 |
| | If you're interested, look at one of the device implementations - there are many to choose from. I would advise staying away from pdfwrite for sanities sake though. | 13:21.15 |
| DrChalisque | Thanks, Robin_Watts, I will do so. | 15:20.11 |
| contrapunctus | o/ | 18:07.26 |
| | I'm trying to extract some pages from a PDF file. Is there any way I can specify some specific, non-sequential page numbers? | 18:09.17 |
| sebras | hm... | 18:29.53 |
| | maybe you guys know this: what is soft proofing? | 18:30.21 |
| | and how does it differ from proofing? I guess the latter is considered "real" or "hard"? | 18:30.43 |
