SVG rendering on Android app based on Readium SDK

Hi, There's an issue with SVG files on Android.

• SVG aren't rendered in this case:

  <img src="my.svg" />

• SVG are rendered in these cases:

  <object data="my.svg" type="image/svg+xml"></object>

  <svg>(my.svg code)</svg>

So I can confirm the issue will apply to background-image as well when it’s SVG (JPG, GIF, etc. are OK), on every Android app I know is using the SDK I could test.

I’ll try to provide a sample ASAP.

So here you go, test file for the background-image case: https://www.dropbox.com/s/t1bkxptt4ptwk59/svg-sample.epub?dl=0

@garconvacher Please feel free to re-use this file and add your use case.

In the following screenshots, when you’re seeing whitespace, there should be a dinkus a.k.a. * * * displayed (SVG background image).

Here is a control capture:

So, from quick testing, apps using the SDK consistently fail at rendering the SVG on Android…

On iOS, it may or may not work depending on the app so I’m correcting my previous statement…

WKWebView seems to be fine…

UIWebView is not…

Which brings the question: could that be a WebView issue?

In this case, I’m afraid that will impact Readium2 as well…
