| yousef | would anyone care to give me some pointers on how to create an image thumbnail from a pdf using the ghostscript (or any other) C API? | 10:16.37 |
| ray_laptop | yousef: if you know what size image thumbnail you want, and what format you can just invoke ghostscript without needing the C API | 10:55.48 |
| | yousef: for instance: gs -g100x100 -dFitPage -sDEVICE=png16m -o thumbnail.png input.pdf | 10:56.51 |
| | yousef: which will create a 100x100 image with the PDF scaled to fit in the 100x100 pixel image. From C you can just invoke gs with the system() call. | 10:58.09 |
| | yousef: if you want to use the C API, consult http://www.ghostscript.com/doc/current/API.htm#Example_usage and just replace the gsargv[ ] strings with those args above. | 11:01.11 |
| | and adjust the gsargc count as well | 11:01.30 |
| yousef | ray_laptop (or ray_pc): thank you. | 18:56.54 |
| ray_pc | yousef: I wasn't sure you were still around. I hope my comments helped. I'll consider this kind of thing for a FAQ | 21:48.06 |
| | we (Artifex staff) have been tasked with coming up with FAQ topics. | 21:48.40 |
| | IDEAS WELCOME for FAQ topics/questions :-) | 21:49.30 |
| | camelopard: I wanted to mention that Artifex has more than one Open Source (AGPL) packages. Besides Ghostscript, there is MuPDF which is a bit more "modern" in coding style (although still C) and MUCH easier for someone new to dive into | 21:57.08 |
| | camelopard: and if you let me know what (generally) your skills and interests are, I can suggest some small (20hr or so) project for you to tackle for one of those projects | 22:01.52 |
| | FAQ ideas: | 22:14.19 |
| | Extract some pages from PS or PDF | 22:14.20 |
| | Combining pages from several files into a single PS or PDF | 22:14.22 |
| | Making thumbnails of all pages in a file or files | 22:14.23 |
| | Converting an image into a PS or PDF file | 22:14.25 |
| | Printing using Ghostscipt/CUPS to my printer | 22:14.27 |
| | Calling GS/MuPDF from my application -- what can I do beyond the command line options, and how do I do it | 22:14.28 |
| | Using Ghostscript as a conversion filter (stdin -> gs -> stdout) | 22:14.29 |
| | | 22:14.31 |
