| psmlbhor | kens, as you had suggested I am going to implement the Flate encoding on image data. The PS reference manual suggest RFC 1950 and 1951 for the implementation details. But can I directly use the zlib library for it? | 14:19.02 |
| | kens, can you help me please ? | 16:16.07 |
| kens | With what ? | 16:16.29 |
| psmlbhor | can I use zlib for Flate encoding? | 16:18.10 |
| | Will PS flate decoder understand the data? | 16:18.29 |
| kens | I don't see why not | 16:19.38 |
| | But I'm not going to say it will either, I don't actually know | 16:19.49 |
| | Try it and see | 16:19.59 |
| | Or, alternatively, use MuPDF which definitely does work, and was suggested several times | 16:20.16 |
| psmlbhor | I just need to compress the data now. Though I have started looking at MuPDF, right now I can't switch right away. | 16:24.11 |
| Robin_Watts | the flate data outputted by zlib is compatible with PS, yes. | 16:38.17 |
| psmlbhor | Robin_Watts, thank you. | 16:39.33 |
| elusiveother | hello | 17:30.08 |
| 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. | 17:30.08 |
| elusiveother | i was wondering if anyone here had advice for someone trying to convert a csv file into a legible pdf document where values are represented in a table | 17:31.13 |
| Robin_Watts | elusiveother: Interesting problem. | 17:35.05 |
| | You need something capable of laying out the text for you. | 17:35.55 |
| | elusiveother: Your easiest approach may be to write a script that reads the csv file and outputs postscript. | 17:36.33 |
| | And then use gs to go from postscript -> pdf. | 17:36.47 |
| | OR, for bonus points, write a PS program to read the CSV file and output PS. | 17:37.11 |
| | PS allows you to measure the strings, so you can be sure the layout will work. | 17:37.31 |
| elusiveother | Robin_Watts, thanks. I'll attempt that if CSV -> Tex -> PDF doesn't work out as well as i'd like | 17:58.44 |
| Robin_Watts | That's not a stupid plan. | 17:59.04 |
| | I might have been tempted to output HTML myself, on the grounds that you can have funky javascript in the html so you can resort by column by clicking on the column headers etc. | 18:00.24 |
| | But if you need PDF, you need PDF. | 18:00.35 |
| kens | Robin_Watts : if you write a PostScript program to read the CSV you can outptu straight to PDF< no need to output to PS | 18:00.59 |
| Robin_Watts | kens: I suspect that's harder to do (requires knowledge of our system rather than vanilla PS) | 18:01.44 |
| kens | No not really | 18:01.51 |
| Robin_Watts | but I bow to your greater knowledge in this area. | 18:01.54 |
| kens | The PostScript program would have to execute PS operations to position the text, just execute them | 18:02.09 |
| Robin_Watts | kens: Oh, I see. Yes. | 18:02.22 |
| kens | And select ps2write as the output device | 18:02.23 |
| | D'oh I mean pdfwrite of course.... | 18:02.39 |
| | I should go away, I'm clearly tired | 18:02.46 |
| Robin_Watts | I'd been thinking of actually putting out a PS program on stdout, but your way is better of course. | 18:02.47 |
| kens | Well, PostScript is a programming language, so.... | 18:03.05 |
| | But there's no reason CSV->TeX->PDF shouldn't work | 18:03.15 |
| elusiveother | what's a good source for learning the postscript language? | 19:43.55 |
| Robin_Watts | elusiveother: There is the PLRM (postscript language reference manual). It's a good reference, but not great as a learning tool. | 20:12.55 |
| | There are also a couple of other books I believe. One is a "Cookbook". | 20:13.20 |
| | and it should be available to download online somewhere I think. | 20:13.30 |
| elusiveother | http://www-cdf.fnal.gov/offline/PostScript/BLUEBOOK.PDF | 20:20.27 |
| | i'm looking at this atm | 20:20.31 |
| kens | There's the Green book and the blue book, that's about it for PS tutorials. In truth I wouldn't seriously reccomend learning PostScript. Another excellent source of inspiration is John Deubert's acumen training journal: | 20:35.16 |
