| Robin_Watts | Morning mvrhel_laptop | 15:35.35 |
| | Sorry, didn't see you appear. | 15:35.42 |
| | Are you here now? | 15:35.45 |
| | mvrhel_laptop: hello? | 15:52.20 |
| | third times a charm.. | 18:31.53 |
| | mvrhel_laptop: Morning! | 18:31.56 |
| mvrhel_laptop | Morning | 18:33.11 |
| Robin_Watts | mvrhel_laptop: So, there is an img2.pdf in my home dir. | 19:44.38 |
| mvrhel_laptop | Robin_Watts: ok | 19:44.49 |
| Robin_Watts | It has a image in it that is in an XObject with a /ColorSpace << /DeviceGray .... >> | 19:45.10 |
| | It looks to me like the default colorspaces are being set to this new space correctly. | 19:45.58 |
| | when I end up in icc_conv_pixmap, we're falling into the "DeviceGray->CMYK as K only" case. | 19:46.23 |
| | If I nobble that, we get results that match acrobat. | 19:46.38 |
| | so, as far as I can tell, we're doing exactly what I reckon we should be, but are somehow getting the wrong result. | 19:47.02 |
| | so I suspect my understanding of what we should be doing is broken :( | 19:47.14 |
| | If you get a mo, can you sanity check it please? | 19:47.24 |
| mvrhel_laptop | hmm so if the image is DeviceGray, and DeviceGray I would expect it to go to K still when going to CMYK is AR not doing that? | 19:47.48 |
| | oops | 19:47.55 |
| | let me rewrite that | 19:48.00 |
| | so if the image is DeviceGray, and DeviceGray is defined in the XObject I would expect it to go to K still when going to CMYK is AR not doing that? | 19:48.26 |
| Robin_Watts | mvrhel: If I understand you... yes, that's what we are doing, and no, that doesn't match acrobat. | 19:48.48 |
| | nobbling it so we DON'T do the gray -> k thing, we match acrobat (as far as I can tell) | 19:49.03 |
| mvrhel_laptop | hmm maybe they dont respect the DeviceGray->K *if* DeviceGray was defined in the file | 19:49.50 |
| | I wonder if the pdf2.0 spec clarifies this | 19:50.01 |
| Robin_Watts | I have to run, sorry. | 19:50.38 |
| mvrhel_laptop | np | 19:50.41 |
| | I will look into this | 19:50.49 |
| | ah looks like page 14 is an overprint confusion | 20:10.12 |
| | Robin_Watts: I found the issue | 20:26.23 |
| | I will write it up and let you fix it | 20:26.33 |
| | Robin_Watts: ok sent | 20:30.09 |
| | Robin_Watts: I may have a simple fix for this | 22:43.05 |
| Robin_Watts | oh, cool. | 22:50.07 |
| mvrhel_laptop | Let me push it | 22:56.08 |
| | It did fix one issue on that page | 22:56.17 |
| | but there is still something going on | 22:56.24 |
| | let me check that my fix did not break the technical overprint | 22:56.44 |
| Robin_Watts | I have to get up early tomorrow, so I'm off to bed. I'll check in the morning. | 23:00.02 |
| | Tyhnaks! | 23:00.06 |
| mvrhel_laptop | ok np | 23:01.57 |
| | pushed | 23:01.59 |
| | good night | 23:02.04 |
| | Forward 1 day (to 2017/08/04)>>> | |
