| GUBLAZ | hi, anyone here who can just explain me how i can use icc file correctly to create an pdfa document with ghostscript? | 06:46.50 |
| | nobody here? | 07:00.35 |
| kens | Just arrived. Your best time to get people in this channel is UK office hours | 07:01.54 |
| GUBLAZ | ah okay, thanks for this hint, so may i can repeat my question kens? | 07:02.58 |
| kens | No need, I haev now read the logs | 07:03.10 |
| GUBLAZ | okay i will wait | 07:03.29 |
| kens | How much do you understand about colour management, and how critical is the colour to your workflow ? | 07:03.32 |
| GUBLAZ | just started with Colour Mgt yet, for this case. The colour is critical in my oppionen | 07:05.16 |
| kens | Then you are going to need to understand colour management thoroughly. | 07:05.41 |
| | And I cannot answer this question in a few words. | 07:06.02 |
| GUBLAZ | okay could u tell me a good documentation? | 07:06.10 |
| kens | The reproduction of colour by Dr RWG Hunt is what I used when I was learnign about colour and printing | 07:06.48 |
| GUBLAZ | what is the way if die colour isnt critical, could we found here a solutions? | 07:06.49 |
| kens | If you don't care about colour fidelity, then you should choose a device space for the PDF/A file (RGB or CMYK IIRC). You can then select any convenient matching ICC profile If you chose RGB then you need a 3 component RGB profile, if you chose CMYK then you need a 4 component CMYK profile. | 07:08.04 |
| | Reference that ICC profile in the PDFA_def.ps file. | 07:08.19 |
| | Our own documentation is here: | 07:09.25 |
| | https://www.ghostscript.com/doc/9.26/VectorDevices.htm#PDFA | 07:09.25 |
| GUBLAZ | okay, i will read this and will come back. Thanks in advance. | 07:10.29 |
| andyrtr | what about the epexted jbig2dec release required for new ghostscript? I can't find it so far anywhere. | 09:33.28 |
| kens | We haven't released the new Ghostscript yet | 09:33.48 |
| andyrtr | but looks like that checking the web page | 09:35.04 |
| kens | Hmmm | 09:35.31 |
| | I'll have to defer to teh release maintainer | 09:35.52 |
| | chrisl ping | 09:35.59 |
| chrisl | I'm working on it | 09:36.18 |
| kens | :-D | 09:36.22 |
| | I didn't realise you'd actually pushed the GS release | 09:36.36 |
| chrisl | Well, I haven't finished yet, hence I haven't sent out the notification | 09:38.25 |
| kens | Ah! Well that would explain it :-) I thought I was being dense | 09:38.52 |
| chrisl | andyrtr: the jbig2dec 0.16 release is on out github downloads area now | 10:07.03 |
| andyrtr | compiling fails here: make so-only breaks now: https://privatebin.net/?8bfef970bd6e5e3e#QEdcANe2CADC+TMwuKzKTPUZDyJfX4hVVodRwhQwlI4= | 11:30.45 |
| | havew you done changes to the makefiles? | 11:30.53 |
| | this is a non-parallel build just for testing | 11:31.06 |
| chrisl | Yeh, gpdl doesn't support a .so target at the moment - if you want a shared lib, get the Ghostscript only archive | 11:35.18 |
| | andyrtr: ^^ | 11:36.03 |
| andyrtr | thx | 11:36.14 |
| chrisl | Although, I'm a little confused why it's trying to build it at all.... | 11:37.25 |
| andyrtr | it worked with 9.26 and ghostpdl source | 11:37.46 |
| chrisl | 9.26 didn't have the gpdl product in it | 11:38.03 |
| | If you prefer, you can make a quick tweak to the makefile(s) that should solve it.... | 11:39.24 |
| GUBLAZ | hi again, i just got it, but i only can create pdfa-2b documents, ist this correkt or may it is possibil to convert pdf to pdfa-2a or perhaps pdfa-3a? | 11:40.57 |
| kens2 | GUBLAZ: No | 11:41.55 |
| GUBLAZ | thx kens2 | 11:42.22 |
| kens2 | The requirements of the 'a' variants for PDF/A mean that we would have to guess at certain aspects of the file (or ignore them) the specification states that producers should *not* guess. | 11:42.37 |
| GUBLAZ | okay and the level 3 spezifikation isnt possibil too? | 11:44.06 |
| kens2 | As I recall there are no significant differences between 2 and 3 | 11:44.27 |
| GUBLAZ | oh did wrote it before sorry and thank u again. | 11:45.47 |
| kens2 | NP | 11:45.55 |
| chrisl | andyrtr: Actually, you don't even need to change the makefiles, just do: make GPDL_TARGET= so | 11:47.36 |
| | andyrtr: altrernatively (given you're packaging stuff) delete/rename/move the gpdl directory in the source tree, and re-run configure. | 11:51.14 |
| | afk for a while | 12:02.22 |
| | Forward 1 day (to 2019/04/05)>>> | |
