Pinch to zoom is not working

[911shanky]

It seems like "Pinch to Zoom" is not working.

Calling camera.setZoom(CameraKit.Constants.ZOOM_PINCH); doesn't work.

Can you resolve this issue quickly.

[Moonbloom]

This is not implemented yet, so there is nothing to "resolve".

If you read the README, you'll see:

Coming soon: Built-in pinch to zoom.

The code to enable the option is in the lib, but the functionality is not there yet.

[android-dataticket]

having huge client demand for this feature, hope it gets implemented soon

[android-dataticket]

i added pinch to zoom, pull #72

[veeranath]

Hi sir i am using this version of the library com.flurgle:camerakit:0.9.17 is pinch zoom is intergated as tried it .Its not working sir

[veeranath]

@android-dataticket i had tried your pull request but pinch to zoom is not working

[samuelhehe]

@android-dataticket i had tried your pull request but pinch to zoom is not working

[adamwlarson]

I took @android-dataticket pull request and integrated into my fork, I had to do a few things to get it working such as passing on the onTouchEvent, I also switched over to a gesture scale. It isn't working perfectly yet, but it is close. I am using jitpack and have a release tagged https://github.com/adamwlarson/CameraKit-Android/releases/tag/1.0.4

[android-dataticket]

sorry I've sorta abandoned this thread @adamwlarson - I made the pinch to zoom pull request and then had to make some more adjustments to get it to work and never updated the PR

looks like you figured it out, i think the creator of this library has abandoned it.. i gave up.

i have a working fork that i use in my app and haven't updated it in months, it gives me some memory issues here and there but it works for the most part, i wish this library was a little more up-kept by the creator but oh well, he's a busy young man i guess

[KalpeshJadvani]

any one to solved this problem plz tell me i was finding from long time

[abhisheksingapore]

Has anyone solved this issue, yet? Pinch to zoom is critical to my app and everything else about this fits my app well except the lack of zoom

[android-dataticket]

@abhisheksingapore @KalpeshJadvani I've updated the pull request with some changes that I made afterwards which work for my application, please note the commented areas which indicates code removal

[aravindhkumar23]

@android-dataticket please confirm when can i get the pinch to zoom feature?

[austinkettner]

@android-dataticket Can you reOpen the PR? @aravindhkumar23 this is something we are working on, you can expect it in the next week.

[android-dataticket]

@austinkettner i am not that great of a programmer and what i've done is forked and tweaked to work with only my application.. for instance consider the following: in my PR, i remove DisplayOrientationDetector - some may need this, but i did not in my PR, i removed the handleFocus(event, params) method call, it gave issues when touching the screen to pinch i also add some quirky try catches and thread sleeps, but if you really want me to do a fresh PR, i will fork a new copy and upload the files that i've changed

[austinkettner]

@android-dataticket No worries! Thanks for the clarity, we are actually working on a solution to this today internally, so no PR needed! Really appreciate your willingness to help though! =)

[aravindhkumar23]

Hi @austinkettner any updates regarding pinch to zoom feature? or any workaround to get it done? i have been waiting for this feature to be implemented in one of my project..

[austinkettner]

@aravindhkumar23 We actually just pushed this in the release/0.13.0 branch (https://github.com/wonderkiln/CameraKit-Android/tree/release/0.13.0), check it out via compile 'com.wonderkiln:camerakit:0.13.0-Snapshot'

[aravindhkumar23]

when i use compile 'com.wonderkiln:camerakit:0.13.0-Snapshot' i get error msg when building gradle

--i'am a newbie in android app development can u guys help me to solve this

[austinkettner]

There is a temporary issue with Bintray current preventing the builds from being accessible, you can use compile 'com.flurgle:camerakit:0.13.0-Snapshot' in the meantime. @aravindhkumar23
