| miha | hello. does mupdf support 3d pdf? http://www.adobe.com/manufacturing/3dpdfsamples/3dsolutions/ | 09:33.19 |
| kens | If you mean the 3D annotations defined in the PDF reference, then no. | 09:33.50 |
| miha | kens: i mean like this adobe url? | 09:34.08 |
| kens | There's a bunch of files there, I'm not really prepared to downlaod multi-megabyte PDF files and look. | 09:34.42 |
| miha | it's 3d models inside pdf, that you can rotate? | 09:35.19 |
| | well, not even adobe reader supports that on android :) | 09:35.37 |
| kens | That sounds very much like 3D annotations, so the answer is no | 09:35.39 |
| | If there is an alternate representation, then MuPDF will display that. | 09:36.05 |
| sebras | miha: no, there is no support for this kind of 3D-rendering in MuPDF. | 09:36.27 |
| miha | sebras: any plans for that? :) | 09:36.48 |
| kens | That would also be a no | 09:36.59 |
| miha | ok, thank you for your answers. | 09:37.07 |
| sebras | miha: however some tools might also render the (often times) rotatable 3D-model into a static 3D-lookalike image (bitmap or vector graphics-based using shadings). if that is the case then MuPDF will show this graphics. | 09:37.57 |
| | miha: may I ask why you are interested in 3D-support? | 09:38.38 |
| miha | company provides 3d printing... so lots of models :) | 09:41.43 |
| | thank you again | 09:43.00 |
| sebras | kens: gs doesn't have U3D support either I imagine..? | 09:43.17 |
| kens | No, it doesn't, it would be even less useful there, since it isn't interactive :-) | 09:43.37 |
| sebras | kens: good point. | 09:43.45 |
| | kens: I know that we have some mesh support due to supporting shadings. | 09:44.22 |
| | but that's about it. | 09:44.34 |
| kens | sebras mesh shadings, yes, certainly | 09:44.38 |
| | But the rest of it, no not at all | 09:44.46 |
| sebras | kens: says nothing about lighting though. I know. :) | 09:44.55 |
| kens | It would be a big project to add it, I'm assuming Adobe bought the technology in. | 09:45.01 |
| sebras | yeah, though it _is_ an accessible ECMA standard should it ever be considered. | 09:46.13 |
| kens | Its always struck me as Adobe just trying to make life difficutl for the clones. | 09:46.35 |
| | THere doesn't seem to be any reasonable use for the ability, otther than 'isn't that cool, look I can rotate it' | 09:47.03 |
| sebras | yeah, I guess this is one area where Adobe are still unique (though it appears to be a very small market). | 09:47.23 |
| kens | I'd have thgouht that if you wanted someone to 'print' a 3D obejct, you'd send them the original model.... | 09:47.27 |
| sebras | kens: indeed. | 09:47.39 |
| kens | Not a PDF from which they would have to extract the model.... | 09:47.43 |
| sebras | I guess this is due to the broad support for this particular format. so anyone<tm> can view the model. | 09:48.05 |
| kens | Like I said, its very 'ooh, aahh', but actual uses ? | 09:48.10 |
| sebras | kens: I agree with you, don't get me wrong. | 09:48.38 |
| kens | I feel sure there are dedicated u3d visualisation tools | 09:48.41 |
| sebras | there is some sample code from 3dif (who developed u3d) over at sourceforget. | 09:49.33 |
| kens | Hmm, my code just dimped an undefined error :-( | 09:49.33 |
| Robin_Watts | is reminded of the policeman from allo allo. | 09:50.03 |
| | My cude has just dimped on indefuned arror. | 09:50.22 |
| kens | My typing is often like that.... | 09:50.27 |
| | I can at least see why now though. | 09:50.42 |
| sebras | gets breakfast | 09:51.12 |
| kens | Robin_Watts : eprintf or empritnf ? which is preferred ? | 09:53.09 |
| | Hmm, -dFirstPage and -dLastPage aren't working properly with pdfwrite. | 09:57.25 |
| | Oh, but it does if I don't run in the debugger, weird.... | 09:59.39 |
| | :-) Turns out I had LastPage sepcified twice, ooops | 10:01.37 |
| Robin_Watts | emprintf | 10:08.23 |
| | basically, always try and use the methods that specify a gs_memory_t * | 10:08.40 |
| kens | :-( I just coded with eprintf, oh well. | 10:08.41 |
| chrisl_away | kens: It looks like Kyocera's own printer driver produces PS with the same complexity problem for that printer..... | 10:34.15 |
| kens | well then I think we are safe to close it | 10:35.31 |
| chrisl_away | I agree, although, it would be nice to try to figure out a way to use fonts and charpaths for this class of file | 10:36.13 |
| kens | True, but it looks like a lot of work, at first glance | 10:36.31 |
| chrisl_away | Hmm, shame - if only the output didn't come from an Adobe product...... | 10:37.28 |
| | kens: do you have any PS printer drivers on your machine, other than the Adobe PDF writer one? | 10:41.44 |
| kens | Not currently | 10:42.47 |
| | But the ps driver is the built in one all that changes is (effectively) the PPD | 10:43.03 |
| chrisl_away | So no one does their own PS driver, these days? | 10:43.40 |
| kens | I don't think anyone produces their own any more no | 10:43.44 |
| | Not for ages reallly. | 10:43.59 |
| chrisl_away | There's a "Print as Image" option in the PS driver, which I'm assuming is included for situations like this | 10:44.23 |
| kens | I woeuld think so, yes | 10:44.31 |
| chrisl_away | I've suggested it's something the cups developers might consider | 10:45.13 |
| kens | Its a reasonable idea, certainly | 10:45.34 |
| | I guess we could do that too ;-) | 10:45.57 |
| chrisl_away | I'm assuming cups already has some boiler plate to take a cups raster and wrap it in a PDL | 10:46.40 |
| | We could do a psimage device, but it seems rather pointless | 10:47.34 |
| kens | I'm inclined to agree, yes | 10:55.09 |
| | I did clsoe the bug as wonfix this morning based on the ubuntu tracker | 10:55.29 |
| chrisl_away | Yeh, I regard the matter as "no longer our problem"..... | 11:01.07 |
| kens | OK lunch and swim, bye all | 11:05.25 |
| blino | hi | 13:59.06 |
| ghostbot | hello | 13:59.06 |
| blino | tkamppeter_: long time :) | 13:59.23 |
| | I have a small patch to fix a hang in gstoraster, I'll open a bug for that | 13:59.41 |
| | tkamppeter_: opened http://bugs.ghostscript.com/show_bug.cgi?id=693336 with a patch | 14:37.59 |
| marcosw | I going to be taking casper offline tonight at 18:00 PDT for an os upgrade. Please save your work and log off. | 15:12.11 |
