| sebras | bhs720: I believe that you may need to run the page to get all the matrices multiplied yes. but wait for tor8 to return here in roughly 6h or so. he's better equipped to answer questions like these than I am. | 03:32.04 |
| Sepultura | Hallo | 07:28.49 |
| delrier | Hello, I came in here friday describing my issue with mupdf 1.13 randomly drawing red backgrounds in areas and sometimes drawing the entire page b&w | 09:03.51 |
| | I'm using java | 09:03.57 |
| | I thought I might share screenshots of this issue: https://imgur.com/a/L9TbESh in case it would give anyone a hint of why this is failing :) | 09:04.27 |
| | I'm not sure if imgur adds extra compresison, but if you want I can send the "raw" pngs & the pdf file itself | 09:05.03 |
| kens | I'd have to see the PDF even to tell where there's a problem. But you probably need to wait for tor to come onlione | 09:06.05 |
| delrier | ok, where would you like me to send/upload the pdf? | 09:07.24 |
| kens | Any public URL, or you can open a bug report and attach it there | 09:07.44 |
| delrier | Thank you for your help, I have now added Bug 699750 | 09:15.49 |
| kens | OK I'll prompt tor when he appears | 09:16.04 |
| | delrier: I hate to say it, but I think an intermittent fault on a 150+ page docuemnt is not going to be easy to investigate | 09:27.58 |
| delrier | no problem, I thought maybe I was doing something obviously wrong when rendering, but if it's a bug I can check back in the next version and see how it's working | 12:10.15 |
| sebras | delrier: I just tried to reproduce your issue, but I'm unable to do so. | 18:00.13 |
| | delrier: I did however look into the PDF and noticed that the area that is pained red in your sample image is coded using a gray ICC profile with the value 0.933. | 18:01.00 |
| | delrier: because I know that mupdf bundles its own lcms, could it be the case that you are instead using your systems lcms? | 18:01.27 |
| | delrier: this might not be the reason, but we've come across a fair number of people that revert to using the system's lcms2 instead of the one we bundle. | 18:02.27 |
| | delrier: oh and the faint white lines you see in the red area is because it consists of several filled rectangles that are close together, but far enough apart to have the white paper shown through the seam. | 18:19.06 |
| | Forward 1 day (to 2018/09/11)>>> | |
