Bad image resize with Android using crosswalk Runtime 19 Embedded

mattias_c_ — Tue, 22 Nov 2016 00:54:17 GMT

I'm using the accepted answer from this stackoverflow question http://stackoverflow.com/questions/19262141/resize-image-with-javascript-canvas-smoothly.

It works perfectly everywhere i try it. Except for Android crosswalk when images are resized from large images to canvas(3000+ pixel image down to 500 pixel canvas). When building with crosswalk the edges get jaggy and looks bad. I know this might be hard to get around but I fgured maybe somebody had any input on why the downscaling when using crosswalk is worse then when not using crosswalk. If so, is there anything I can change to downscale better?

(It works good in Android when not using crosswalk, incase i was unclear)

Any help or input is highly appreciated, thanks!

EDIT: Just noticed that big images looks bad in crosswalk overall(not that i try to use this big images, just want to scale them down, but the problem might be related).

Steps to reproduce,

1. get a big image, like 4000x4000 pixels for instance.

2. Set as image src to an image tag

3. Compare crosswalk with default browser/runtime

You might also try different

You might also try different versions of Crosswalk, that might make a difference.

Ye, tried them all between

Ye, tried them all between version 14-19. I Guess that there's not much i can do or do you have any suggestions? Is it possible to give the crosswalk team feedback somehow or something? kinda stuck, Thanks

You can provide feedback

You can provide feedback directly to the Crosswalk team. There is a Jira database, but I think you need to request permission to add to it > https://crosswalk-project.org/jira/ <
