| kens | Hmm, just found a shorter flight to Mauai, 18 hours 5 minutes with Air Canad via Calgary | 11:43.55 |
| | 1 stop in Calgary for 1 hour 40, gets into Mauai at 20:10 | 11:44.28 |
| | The downside is the return is 27.5 hours, though even that is better than BA | 11:47.10 |
| | Aha, but on the Air Canada site I can get that down to 22.5 hours. Looks like the Canadians win eh ? | 12:00.40 |
| | also the Air Canada site claims laptop power in economy seats too. | 12:01.57 |
| kens | heads for the shower | 12:04.23 |
| robin_watts_mac | morning mvrhel_laptop - good flight back? | 13:20.13 |
| mvrhel_laptop | not back yet. in michigan now | 13:26.54 |
| robin_watts_mac | oh, of course. | 14:16.10 |
| benbro | is there a command to embed fonts in a pdf without changing anything else? | 16:03.08 |
| | I'm using this: "gs -o new.pdf -sDEVICE=pdfwrite -dEmbedAllFonts=true old.pdf" | 16:03.56 |
| | but I'm not sure if it changes images or does other stuff | 16:04.10 |
| robin_watts_mac | benbro: That will completely change the PDF. | 16:05.34 |
| | It will strip it down to graphic objects and rebuild it. | 16:05.50 |
| benbro | robin_watts_mac: will it preserve the original image resolution? | 16:06.46 |
| | will it change the appearance? | 16:06.53 |
| | for example I see the option -dPDFSETTINGS=/prepress but I won't to use the same images | 16:07.23 |
| robin_watts_mac | benbro: The graphic operations may result in different data in the file. | 16:07.42 |
| | broadly the appearance will be the same, but things like resolution/colorspace etc may change acording to your options. | 16:08.02 |
| benbro | how can I tell gs to not change resolution and colorspace? | 16:08.25 |
| robin_watts_mac | You can't, broadly. | 16:08.38 |
| benbro | so if I'm using -dPDFSETTINGS=/prepress it will result with a bigger file? | 16:08.53 |
| | and if I won't use it, images might get lower resolution? | 16:09.03 |
| kens | If you use the default options pdfwrite will endeavour not to alter the original data. | 16:09.50 |
| | Image data may be differently (loslessly) compressed, but it will not be downsampled, colour spaces will remain teh same etc. | 16:10.25 |
| benbro | kens: this will embed fonts and fix corrupted pdf without changing resolution? ""gs -o new.pdf -sDEVICE=pdfwrite -dEmbedAllFonts=true old.pdf"" | 16:10.56 |
| kens | But as Robin says, we do not treat the original PDF as a series of black boxes, the source file is completely interpreted to graphics objects, and the primitives built up into a new PDF file. | 16:11.18 |
| benbro | that's ok as long as the output is the same | 16:11.51 |
| kens | benbro, fonts may or may not be mebedded, it depends on whether a suitablel replacemnet font is available, the format of the font and so on | 16:11.57 |
| benbro | do I need to add the following options? "-dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT" | 16:12.26 |
| kens | No | 16:12.36 |
| benbro | ok | 16:12.39 |
| kens | The command line options are documented in ghostpdl/gs/doc/*.htm | 16:12.55 |
| benbro | I'm using it to fix corrupted pdfs and embed fonts on the server from the command line | 16:12.56 |
| kens | benbro you aren't 'fixing' a broken PDF, you are creating a brand new PDF file | 16:13.22 |
| | Which hopefully is not broken | 16:13.33 |
| robin_watts_mac | What you are doing is 'embedding ghostscripts guess at what font was meant'. | 16:13.42 |
| benbro | in my case I just need to embed the fonts | 16:13.47 |
| | that's good | 16:13.58 |
| kens | But if the original file is broken, all bets are off on the quality of teh output. Content may be missing for example | 16:14.01 |
| sebras | is the meeting over now? | 19:27.56 |
| | Forward 1 day (to 2013/09/09)>>> | |
