Pinch to zoom - Githubissues

JonathanWi commented 9 years ago

Very nice update using the animated library! It really is smoother and lighter!

Do you think it would be possible - just like facebook lightbox - to enable a pinch to zoom?

Have a great day

oblador commented 9 years ago

Hi, yeah it's on my todo. Thinking of maybe writing a carousel to go with it too. Just need some time to do it ;-)

JonathanWi commented 9 years ago

Awesome news then! Could you ping me when it's up?

Cheers

I'm feeling the pressure haha. I've implemented this in the navigator-refactor branch.

See https://github.com/oblador/react-native-lightbox/issues/8#issuecomment-160352712 for more info.

Hi @oblador, I'm getting this to work fine on iOS but not on Android. When I click to zoom, it zooms in but doesn't pinch to zoom. It also scrolls but doesn't drag left to right to see details cut off from initial zoom. I'm using your navigator example and also cloned the navigator-refactor branch during npm install. Any help is appreciated. Thanks!

oblador commented 8 years ago

@kwokster10: I'm aware of that issue, that's because ScrollView on android doesn't support zooming. I'm not sure if I should implement zooming for android completely custom or just wait for support to land in React Native core.

kwokster10 commented 8 years ago

Oh, interesting. Is there a workaround for this? Would using ViewPagerAndroid make a difference? Thanks!

oblador commented 8 years ago

@kwokster10: ViewPagerAndroid might help with paging the images but I don't think it'll help with zooming. Should be able to do zooming with scale transforms, but it wouldn't be as fluid as native zooming nor give you higher detail when zooming.

Hello, i couldn't get to work the version from the navigator refactor branch.. I get the following error:

Element type is invalid: expected a string but got:object. Check the render method of image.ios.js

The main branch works without problems for me. I'm on react-native 0.25.1

For those who can't get the navigator-refactor working for some reason but would like pinch-to-zoom, Wrapping an image in a ScrollView and setting swipeToDismiss to false does the trick (assuming you prioritize zooming above swipeToDismiss)

<LightBox
        key={i}
        swipeToDismiss={false}
      >
        <ScrollView
          minimumZoomScale={1}
          maximumZoomScale={2}
          centerContent={true}
        >
          <Image
            style={styles.image}
            source={{'uri' : source}}
          >

          </Image>
        </ScrollView>
      </LightBox>

I realize this is not ideal, but it's a quick and easy fix for a small feature

@oblador: just curious about timing, are you still working on this?

oblador commented 8 years ago

@braco: Not actively currently but I will soon need this functionality for a project I'm working on, but with NavigationExperimental so consider the navigator branch dead. Hopefully I'll be able to release something more generic for NavigationExperimental but I can't promise it right nor do I have a timeplan.

braco commented 8 years ago

@oblador: thanks for the clarification. Sounds like there's a bunch of hungry puppies waiting for you here, myself included!
