| Emran | hey guys, any examples on adding text annotations with MuPDF | 09:12.44 |
| | ? | 09:12.45 |
| Asuran | kens, if i can bother you a sec: -sOutputICCProfile where thas the profile file to be? (using windows 10) | 11:18.31 |
| kens | anywhere you can set a path | 11:18.52 |
| Asuran | if i want make sure its finding it, where could i place it in the gs folder? | 11:19.53 |
| kens | It won't 'find it' unless you specify a full path and name | 11:20.52 |
| Asuran | ah now i get it, i thought you mean enviorment variables | 11:22.39 |
| | so you meant instead the path inside the actual -switch | 11:22.49 |
| | thank you kens | 11:22.52 |
| kens | Yes, -sOutptuICCProfile=/path/filename | 11:23.03 |
| kens | heads for early lunch | 11:23.15 |
| BlearyEyed | Have used mupdf1.9a to clean a 200mb pdf. | 13:19.37 |
| | I'm trying to shrink the pdf size. In Acrobat this is fairly simple. But I get an out of memory error when trying to do so. | 13:20.37 |
| | Can mupdf shrink like Acrobat. It often reduces the size by %50 | 13:21.20 |
| tor8 | BlearyEyed: have you tried "mutool clean -ggz in.pdf out.pdf" ? | 13:30.05 |
| BlearyEyed | not yet. will give it a try. | 13:30.32 |
| tor8 | that does a syntactic reconstruction of the PDF file, and compresses the data inside if it's not already compressed | 13:30.56 |
| | it may or may not decrease the size | 13:31.02 |
| | the -gg is to garbage collect and remove unused objects, and compact the cross reference table to skip empty slots | 13:32.11 |
| | the -z is to compress embedded data streams | 13:32.22 |
| BlearyEyed | tor8 do you have any idea what "Reduce Size" does in Acrobat? | 13:35.40 |
| tor8 | BlearyEyed: sorry, not a clue | 13:35.57 |
| BlearyEyed | what does the -s switch do? It says clean content streams. Not sure what is meant. | 13:37.43 |
| tor8 | BlearyEyed: content streams are the page graphics; in essence a simplified postscript program to draw the page | 13:39.14 |
| | we can interpret the page graphics and do some optimizations on the commands and recreate those | 13:39.30 |
| | that could potentially save some space, but it's more used to clean up syntax errors so that we can add stuff to a page and know that the graphics are in a known good state | 13:41.22 |
| BlearyEyed | I received this "error: freetype: cannot load font: broken file <nl> error: cannot load embedded font (61009 0 R) <nl> warning: ignored error when loading embedded font; attempting to load system font | 13:45.43 |
| kens | Sounds like your PDF file has a broken font. | 13:46.19 |
| BlearyEyed | :) | 13:46.39 |
| kens | You could try running it through Ghostscript, it has a slightly difernt impleentation of FreeType and it *might* be able to fix it. No guarantees though | 13:47.48 |
| BlearyEyed | k | 13:47.57 |
| kens | You'll want somethijng like gs -sDEVICE=pdfwrite -o out.pdf <input filename> | 13:48.56 |
| BlearyEyed | its gonna take a while ~17k pages | 14:08.51 |
| kens | Well, you did say 200 Mb | 14:10.13 |
| BlearyEyed | I'm getting Range check errors on a few pages. Any idea what that means? | 14:11.20 |
| kens | Something bad happened | 14:15.43 |
| | Probably its your broken font. GS will continue and try to do the rest of the file, but frankly there are going to be bits missing in all likelihood. | 14:17.24 |
| | check the pages the errors occured on | 14:17.42 |
| | But ti sounds to me like your file is sadly broken | 14:17.52 |
| elusiveother | why does a font effect a graphics format? | 14:17.58 |
| kens | Because hte font gets used to draw the graphics :-D | 14:18.13 |
| elusiveother | all fonts are broken | 14:18.54 |
| BlearyEyed | Where is the log file for the gs output? | 14:20.04 |
| kens | There is no log file, it goes to stdout | 14:20.33 |
| | If you want it logged you have to send stdout to a file | 14:20.41 |
| BlearyEyed | I'm gonna have to run it again I think if I want a log | 14:21.10 |
| kens | Its probably not worth it, it sounds like your basic problem is the file is damaged in some way | 14:21.32 |
| BlearyEyed | is there a switch to input multiple pdf files,clean them then outpu to individual files? | 14:34.18 |
| | ie recursive clean | 14:35.50 |
| kens | you talking about GS or MuPDF and I'm no sure what is recursive about that | 14:36.14 |
| BlearyEyed | mupdf | 14:36.45 |
| | recursively take in a file clean it and generate file name with -out appended for an entire directory of files | 14:38.21 |
| kens | If you take in one PDF file, why would you get a directory of PDF files as an output ? | 14:38.50 |
| | are you saying you wnt each page in the original PDF produced as a separate PDFNfile ? | 14:40.00 |
| BlearyEyed | let me clarify. If I have a directory of 100 pdf files. Can I recursively clean them? | 14:40.11 |
| kens | sAgain, I don't understand your use of 'recursively' | 14:40.39 |
| BlearyEyed | where the out put would be filename-out.pdf | 14:40.47 |
| kens | You can easily write a shell script which runs MuPDF for each file i a directory and write each outptu file to a new directory | 14:41.01 |
| BlearyEyed | can that be done through mupdf in the same directory? | 14:42.03 |
| kens | As I said, you oculd wrie a shell script to invoke MuPDF on each file in a directory | 14:43.07 |
| BlearyEyed | ok | 14:43.18 |
| elusiveother | i'm actually having quite a bit of fun playing with postscript | 17:09.51 |
| | dynamic random grey boxes! | 17:10.00 |
