zoomage's Issues

How to find coordinates of touch on the image

Hi, is there any way of finding where the user has tapped on the image?
(I'm a bit new to android studio)

Add pinch translatable

Would be awesome to be able to translate only with pinch in stead of single finger.

Issue resetting zoomed image before changing image

When image is zoomed right in then change images the new image is at the same zoom level as the last image even if I do a ZoomageView.reset() first.

Is there a way to reset the zoom to 1?

Can't swipe ViewPager

After update to 1.3.0 i can't swipe to left right inside viewpager. How can i fix it?
I can't change images

Can't be used in ViewPager2 because swipe doesn't work

Unfortunately it doesn't work with ViewPager2. I can zoom in the photo but the ViewPager's swipe is broken so I can't see my next photos in the slideshow.
This library seems to work with but there is no customization like yours

Issue when changing orientation in a ViewPager

When you change orientation, the images change dimension and position (they become smaller and at the top corner). No idea why.

support library

this is what i get when i want to sync the project

Double tap zoom is not working

hi admin please enable also double tap zoom feature

Add zoomage_ before all XML attrs

This more closely guarantees a safe XML attribute declaration, since zoomage_ will be a part of the attribute's name.

Add xml attrs file to the aar package

Hi! Just tried your library today and it works wonderfully! Thank you very much for releasing it.

But when I tried to use some attributes, Android Studio complained that it couldn't find them. After inspecting the aar file, I noticed that the attrs.xml file is missing inside the res folder.

Issue with ViewPager

When i zoom image and swipe left or right then view pager swipe not image.

Feature Request: Restrict Scale to One Dimension

I'm looking to restrict the scale to page width for the purpose of scrolling through multiple pages vertically.
Thank you for this library

Add support to clickListener

I'd like to handle clicks on the imageview, but when I call setOnClickListener, the listener isn't called.

I think onTouchEvent needs to be patched to detect when a click was done and call the performClick method accordingly.

Thanks for all the hard work!

View gets locked when changing layout params

Hi, I'm trying to make that a ZoomageView gets "fullscreen" when you double touch it, instead of simply zooming.

To make that, I've created a custom GestureDetector, this code:

class GestureListener(private val mainActivity: MainActivity) :
    GestureDetector.SimpleOnGestureListener() {
    companion object {
        private const val TAG = "GestureListener"
    }

    private var zoomed = false

    override fun onDoubleTap(e: MotionEvent?): Boolean {
        super.onDoubleTap(e)

        val displayMetrics = DisplayMetrics()
        mainActivity.windowManager.defaultDisplay.getMetrics(displayMetrics)
        val screenHeight = displayMetrics.heightPixels
        val imageViewParams = mainActivity.imageView.layoutParams
        imageViewParams.height = screenHeight * 1 / 2
        mainActivity.imageView.layoutParams = if (zoomed) imageViewParams
            else ConstraintLayout.LayoutParams(
                ConstraintLayout.LayoutParams.MATCH_PARENT,
                ConstraintLayout.LayoutParams.MATCH_PARENT
            )
        zoomed = !zoomed

        mainActivity.imageView.invalidate()

        return true
    }
}

What I'm trying to do there is to set the imageView's height to half the screen height, and when you double click, it fills the parent view.
The thing is that some times (mostly always) when the view changes size it gets blocked, I can't zoom in, out or move the image, and I have to close and reopen the app, to see the same behavior again.
I'm not getting any errors, so I am a bit confused.
I've tried doing it the ugly way, creating two imageView, and when double clicking one hiding that, and showing the other, see this code:

class GestureListener(private val mainActivity: MainActivity) :
    GestureDetector.SimpleOnGestureListener() {
    companion object {
        private const val TAG = "GestureListener"
    }

    private var zoomed = false

    override fun onDoubleTap(e: MotionEvent?): Boolean {
        super.onDoubleTap(e)

        visibility(mainActivity.sector_imageView, !zoomed)
        visibility(mainActivity.imageView_full, zoomed)

        zoomed = !zoomed

        mainActivity.imageView.invalidate()
        mainActivity.imageView_full.invalidate()

        return true
    }
}

Where visibility is:

fun visibility(view: View, visible: Boolean, setGone : Boolean = true, debug: Boolean = false){
    view.visibility = if(visible) View.VISIBLE else if(setGone) View.GONE else View.INVISIBLE
}

But I am having the same issue. Locked view, no errors... What am I doing wrong? Thanks in advance.

No method to retain zoom level

Hi! I need to retain the zoom level when drawable changes in the view. Currently when I show thumbnail in the ImageView and zoom the image then when Glide loads the actual image. The zoom state is reset, I need to retain it in that case.
Currently I've handled it like this:

    @Override
    public void setScaleType(@Nullable ScaleType scaleType) {
        // To retain zoom level on Drawable change i.e. when actual image loads after thumbnail
        if (!isZoomed()) {
            super.setScaleType(scaleType);
        }
    }

Image disapears on zoom out when the image gets to minimum zoom level

Tested under Android 10 on Moto G8 plus
As already described when zoom out to the maximim possible value suddenly the image disapears and will not re-appear. Just to check I added a button that lets me do a reset(). But that does not change anything.

Default load image to fullscreen

Hello,
I set scaltype fitxy and set image width,height match_parent still image not show to fullscreen.

Get position touched by user

I need to show a map who will receive user interactions to point some events in my app. There is a way to get the right position (x/y) when the image is zoomed? I found a similar question where you say to use Matrix to do that, but I don't know how to do it.

Status Code 409 Conflict

Hey Jeff,
I've used zoomage in my Android applications before with no error, but I'm getting an error now. See notes below. Hope you can help.

When loading an Android application with the zoomage dependencies, I get the following gradle error:

Error:Could not GET 'https://oss.jfrog.org/artifactory/oss-snapshot-local/com/android/support/appcompat-v7/25.3.1/appcompat-v7-25.3.1.pom'. Received status code 409 from server: Conflict
Enable Gradle 'offline mode' and sync project

When I go to the site in the error message (https://oss.jfrog.org/artifactory/oss-snapshot-local/com/android/support/appcompat-v7/25.3.1/appcompat-v7-25.3.1.pom), I see:
{ "errors": [ { "status": 409, "message": "The repository 'oss-snapshot-local' rejected the resolution of an artifact 'oss-snapshot-local:com/android/support/appcompat-v7/25.3.1/appcompat-v7-25.3.1.pom' due to conflict in the snapshot release handling policy." } ] }

Any idea what's going on?

Thanks

Zoom is very difficult when you are inside a ScrollView

When the ZoomageView is inside an ScrollView and your content doesn´t fit in the screen and the scroll view is enabled, using the ZoomageView functionality is a mess because it conflicts with the scroll bar.

How to get visible zoomed image?

I cant seem to find the appropriate way to get the visible zoomed image

Add support for rotation

Since we have translation and scale, we may as well get crazy and add an option for rotation as well. Rotation would require twisting two fingers past a threshold, optionally resetting after, same as translation and scale.

Zoom factor

How can i get zoom factor?
ex. zoomed (2x), zoomed (1.63x)

Edit:
and also how can i get x and y coordinates of displayed part of ZoomageView after i zoom in?

support exoplayer :D

awesome library! any hints for videos though?

Single tap is also causing image to zoom

I open image in a separate activity and zoom works fine for the first time. But when I open this activity again, it zooms on a single click (To the maximum zoom) which is undesirable. Can you please check this issue.

Thanks in advance!

Image is cropped when restrictBounds is true and scaleType is FIT_XY

Description

When you set restrictBounds = true and the scaleType property for the view to FIT_XY, the image gets cropped.

Note: This bug is inconsistent and may require you to zoom in, out and move the image slightly.

Undesirable zoom when entering page with ViewPager2

I have such a problem - when scrolling with view pager some of the pages are auto zoomed a little and after a second they revert to original size. This seems to not occur when scale type of an imageView is set to Matrix, but not confirmed. I have a default configuration in code, nothing custom. Additionally autoReset seems to not work everytime i lose interaction with image.

app:zoomage_autoResetMode="ALWAYS"
app:zoomage_restrictBounds="true"
app:zoomage_animateOnReset="true"
app:zoomage_autoCenter="false"
app:zoomage_translatable="false"
app:zoomage_zoomable="false"
app:zoomage_minScale="1"
app:zoomage_maxScale="5"
app:zoomage_doubleTapToZoom="false"

After setting a bigger Bitmap you can't zoom out

If the Bitmap set by setImageBitmap(Bitmap) is bigger than the bitmap that was loaded before, it is impossible zoom out enough to fit into the View

Wrong value of view getWidth and getHeight

I am using your library for zooming view.
When I get width value and height value using getWidth and a getHeight method respectively.
But, It gives me the wrong value.

I want width value and height value for making bitmap.
After I append some value it is working well. Show below Ex.

For Example.

zoomage.getWidth() is wrong value.
(int) (zoomage(zoomage.getWidth() * 1.010)) is right value.

zoomage.getHeight() is wrong value.
(int) zoomage(zoomage.getHeight() * 1.010) is right value.

I also tried with Default ImageView and It gives the right value.

Unable to Scroll in Sanpping RecyclerView

Emulator OS Android 10.

Unable to scroll through a snapping RecyclerView.

item_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

and finally setting up a snaphelper in the fragment:

snapHelper = new PagerSnapHelper();
snapHelper.attachToRecyclerView(screenshotsRecyclerView);

While the image is zoomable, user is unable to scroll through the list.

How to connect Zoomage with Seekbar

I am really really stuck at this point

@Override
public void onRangeChanged(RangeSeekBar view, float leftValue, float rightValue, boolean 
isFromUser) {

    **_//What should i do here_**

}

@Override
public void onStartTrackingTouch(RangeSeekBar view, boolean isLeft) {

}

@Override
public void onStopTrackingTouch(RangeSeekBar view, boolean isLeft) {

}

Location of Drawable

Is there a way to get the position of the drawable displayed by the ZoomageView?
I'd like to be able to programmatically access the current size and current position of the drawable.

Image bounds are not restricted when zooming.

I have a ZoomageView with zoomage_restrictBounds set to true, and when dragging with a finger, this is perfect, but when you drag with two fingers, when zooming, for example, it allows you to exit the boundaries.
Is it a bug, a feature or I do need to set up something else?
Thank you very much.

Add support for double-tap to zoom

Great library, thanks !
Would be nice if it allowed to zoom-in/zoom-out of the image by double-tapping on it.

Double-tapping would toggle-animate between the full-screen state and the original image size, which seems to be the standard behavior of most image-viewing widgets.
