SVG can not be rendered properly (Images in zim file does not show up) #1014

Closed sonusourav closed 4 years ago

sonusourav commented 5 years ago

Describe the bug Images in some Zim files do not show up. The case is with some files and not all.

Expected behavior The images should load correctly and not have any broken link

Steps to reproduce the behavior:

  1. Open WikEM (37.3 MB).
  2. Scroll down to see.

Screenshots

broken images

Environment

kelson42 commented 5 years ago

@sonusourav Please secure with kiwix-serve that this is not a problem with the ZIM file itself (missing image in the ZIM file)... And then give a concreate zim/page so we can reproduce the problem.

sonusourav commented 5 years ago

@kelson42 I checked from kiwix-server, the zim file is fine there.

kiwix_desktop

Even after I deleted the zim file from my mobile device and re-downloaded, the issue persists. Is anybody else getting the same problem? Here are the file details: Project: WikEM Size: 37.3 Lang: English (en) Date created: 08-10-2018 Additional info: Contains pictures

@sonusourav @kelson42 The images are not loading even when the device is connected to kiwix-server. I would like to work on this bug, is anyone else working on it?

kelson42 commented 5 years ago

I confirm the problem with 2.5 and recent version of WiKem homepage. I can also confirm that the problem is not with the ZIM.

macgills commented 5 years ago

@mhutti1 would this have anything to do with the redirect problem being addressed in #1368 ?

mhutti1 commented 5 years ago

I guess it could theoretically. Will be interesting to see if it is fixed by it.

I am completely unaware of how to diagnose this. 2019-09-06 14:05:10.319 17627-19257/org.kiwix.kiwixmobile D/kiwix: reading I/m/Kaji-Title-v3-Print-COVER-AMAZON.jpg%3Fresize%3D232%2C348.svg(mime: image/svg+xml, size: 8439) finished. this reading seems fine? is it a problem with svgs? If so will we have to detect the mime type and write out custom html at ZimContentProvider.TransferThread.run()? @mhutti1

mhutti1 commented 5 years ago

This could be to do with redirects (are you using the fixed version)? Otherwise it might be svgs?

macgills commented 5 years ago

Using the fixed version. If there is any way I can debug further to get more info please let me know.The quickest way to patch up my knowledge on kiwix rendering is unfortunately to ask a lot of pestering questions

kelson42 commented 5 years ago

@macgills Have you checked the webView can display SVG properly?

kelson42 commented 5 years ago

@macgills I have uploaded a test ZIM with a SVG here http://tmp.kiwix.org/svg_test.zim... unfortunately I was not able to test it... because Kiwix crash at the time I try to open it!!!!

macgills commented 5 years ago

that would be this issue that I fixed

edit: and will quickly lead to this issue, as a workaround just rely on kiwix file scanning

kelson42 commented 5 years ago

OK, so my conclusion is WebView is not able to render properly SVG. This won't be a problem for which we can quickly find a solution.

from that test file, aye. SVG support has been apart of Webviews in android since 3.0 though. I can navigate on my device browser to a Wikipedia article on svgs that has them there

kelson42 commented 5 years ago

@mgautierfr @macgills Something special in the libkiwix JNI? Kiwix-Desktop and Kiwix-serve have no problem with it!

kelson42 commented 5 years ago

@macgills Hmm.. no it works for me on Android. Are you able to get the test file working... or it simply fails like I said first?

macgills commented 5 years ago

@kelson42, after downloading it I can find it with the kiwix app and then open it and the image is not displaying

macgills commented 5 years ago

I am not sure what was happening but on develop I can now open that test svg file and it displays image

macgills commented 5 years ago

is WikEM full of broken links for anyone else? When I click Kaji Review Volume 3 I get taken to a blank page because it tries to load nothing

The only difference I really see is that the WikEM svg is under I/m/ whereas test svg is under I/ and I very much doubt that is the cause. @kelson42 is anyone available to see if kiwix desktop etc does some particular handling of svg urls? I do not see a way forward with this ticket as of right now

macgills commented 5 years ago

https://blog.wikem.org/empty-mobile-app/ there is no possible way this should be able to affect us... On their website the svgs are now just jpgs

kelson42 commented 5 years ago

I have to move the ticket to 3.1 because so far nobody seems to have a clue about it and I don't want to block 3.0 because of it.

I think this file is lying about being an svg, I am not incredibly well versed on the formats but the byte difference is a lot WikEM:

The WikEM seems to just be a jpeg/jfif? @kelson42 I would say if we recreated the zim file now this issue would disappear

kelson42 commented 4 years ago

OK, I close the ticket. Seems to work fine with proper SVG files.
