| jaeho | Hello, I am justing starting to use mupdf on iOS project. And I have a strange problem which I cannot seems to figure out. | 12:44.00 |
| | I was able to build and test run sample iOS project, But when I try to incorporate mupdf to my iOS project, I get below error message. | 12:44.39 |
| | Undefined symbols for architecture i386 fz_new_context_imp() | 12:44.51 |
| | What is this error about? Thanks in advance for any help. | 12:45.24 |
| StarryEyes | Hi all | 14:33.35 |
| | is there a way to detect tables in the mudraw? | 14:33.47 |
| Jogux | jaeho : is that the only error you get, or are their lots of them? | 18:55.28 |
| | starryeyes : what do you mean by 'detect'? | 18:56.24 |
| StarryEyes | Jogux, I am trying to extract html ... current version does not add tr td tags automatically.... so trying to add these tags manually.... so I thought to ask here is there a method already available | 18:58.01 |
| Jogux | ah. right. I'm not sure then. The matching is all heuristic based; you may need to pop back on a weekday and try to catch one of the mupdf developers. | 18:59.11 |
| StarryEyes | Jogux, Sure! | 19:03.00 |
| robin_watts_mac | StarryEyes: Hi | 19:37.32 |
| StarryEyes | robin_watts_mac, Hi! | 19:37.51 |
| robin_watts_mac | StarryEyes: presumably you are creating a text device and then running an fz_page to it? | 19:38.07 |
| StarryEyes | robin_watts_mac, yes! | 19:38.20 |
| robin_watts_mac | That will give you style sheets/pages etc. | 19:38.24 |
| StarryEyes | You are right! | 19:38.34 |
| robin_watts_mac | Are you then calling fz_analyse_text on the results. | 19:38.39 |
| | ? | 19:38.40 |
| Jogux | declares Robin_Watts's "holiday" to be unusual. :) | 19:38.50 |
| StarryEyes | correct | 19:38.51 |
| robin_watts_mac | ok, fz_analyse_text is where we attempt to spot columns etc. | 19:39.14 |
| | sometimes we manage it, sometimes we don't. | 19:39.21 |
| | If you then call the fz_print_page_as_html (or whateer it's called) method, you might possibly get tables out. | 19:39.48 |
| | but fz_analyse_text is far from foolproof. | 19:40.06 |
| | Jogu: I've done bugger all work. That's an unusual holiday :) | 19:40.32 |
| Jogux | :-) | 19:40.38 |
| robin_watts_mac | StarryEyes: Any improvements etc for fz_analyse_text gratefully received :) | 19:41.35 |
| StarryEyes | robin_watts_mac, :) | 19:41.52 |
| | robin_watts_mac, what is algorithm that you could suggest? | 19:49.21 |
| robin_watts_mac | StarryEyes: for the logs... I can't suggest an algorithm. There is no recognised "best" algorithm for this. It's still an area of research. | 20:08.24 |
| | I've implemented some hairy heuristics that attempt to guess various things (like hanging indents, columns etc) and seem to do a reasonable job for some files, but it's still far from perfect. | 20:09.07 |
| AndroidDeveloper | hey guys | 20:55.09 |
| | I need some help regarding mupdf to read a pdf file | 20:55.23 |
| Jogux | well, that's a good thing to try and do with mupdf; where is it proving tricky? | 20:56.08 |
| AndroidDeveloper | when i open a pdf file using the mupdf through ChoosePdfActivity, it gives me this exception Exception Ljava/lang/UnsatisfiedLinkError; thrown while initializing Lcom/artifex/mupdfdemo/MuPDFCore; | 20:57.02 |
| | any clue what am i doing wrong over here? | 20:57.12 |
| Jogux | my first guess would be issues with loading the native library, libmupdf.so or something like that. | 20:57.47 |
| | I presume the example project works okay for you? | 20:57.54 |
| AndroidDeveloper | i am using the example project, haven't modified any bit of the code | 20:58.14 |
| | i just put a pdf file in my emulator, and opened it though the sample project | 20:58.33 |
| henrys | Jogux: haven't seen a change yet, I wonder if Miah's push failed again. | 20:58.45 |
| Jogux | henrys : I've not had a further update; he's not been online today :-( | 20:59.48 |
| AndroidDeveloper | and here is the first line of following exception trace AndroidRuntime(10838): java.lang.ExceptionInInitializerError 04-07 01:54:02.053: E/AndroidRuntime(10838): at com.artifex.mupdfdemo.MuPDFActivity.openFile(MuPDFActivity.java:213) | 21:00.30 |
| Jogux | androiddeveloper : it's probably worth having a read through mupdf/platform/android/ReadMe.txt - there's a fairly long list of steps that you need to make sure you've done every one of successfully | 21:01.57 |
| | henrys : if he doesn't appear tonight I'll try and get hold of him in the morning | 21:02.24 |
| | (it's 10PM over here just now) | 21:02.34 |
| henrys | Jogux: okay thanks | 21:02.58 |
| AndroidDeveloper | Jogux, i happen to saw that list, it was really long and i ignored it, lol | 21:04.04 |
| Jogux | androiddeveloper : okay, that may explain it ;-) | 21:04.17 |
| AndroidDeveloper | the readme doc says some about setting the environment variables, in the latest Android sdk it was never required to explicitly set those variables, should i still be setting them on my mac? | 21:07.39 |
| Jogux | which step mentions that? | 21:08.29 |
| AndroidDeveloper | step 2 in the dc | 21:10.04 |
| | doc* | 21:10.07 |
| Jogux | I think you still need to explicitly add the ndk directory to the PATH | 21:10.41 |
| AndroidDeveloper | 1 & 2 both , here is the text | 21:10.41 |
| | 1) Download the android sdk, and install it. These instructions have been written with r14 (the latest version at time of writing) of the SDK in mind; other versions may give problems. On windows r14 unpacked as: C:\Program Files (x86)\Android\android-sdk on Macos an older version installed as: /Library/android-sdk-mac_x86 on Linux install it as: mkdir ~/android-sdk cd ~/android-sdk tar ~/Downloads/an | 21:10.43 |
| Jogux | I think both those apply; they certainly need to be in your PATH anyway, just echo $PATH to check if they are or not :-) | 21:11.12 |
| AndroidDeveloper | okey :) | 21:11.25 |
| Jogux | getting the developer tools setup is one place where android really sucks compared to iOS, imho :-( | 21:12.06 |
| AndroidDeveloper | LOL, well it never gave me the problem though i hve been using third party libraries quiet extensively, mupdf is first in my career that demands these manual configurations, though i am not that expert of these things, i remember that 2nd semester of my graduation was the last time whe i set environemnt variables explicitly when we used text editor to code | 21:14.05 |
| Jogux | partly mupdf is more tricky because it includes native code, so the ndk needs to be properly setup. | 21:15.43 |
| AndroidDeveloper | agree with you, doing it right away | 21:16.07 |
| | Forward 1 day (to 2014/04/07)>>> | |
