Versions 0.3.1, 0.3.2, and 0.3.3, which have been tagged on Github, seem to be unavailable from Jitpack.io. The main error in the build logs there seems to be: Could not resolve com.android.tools.build:gradle:8.0.0..

Setting a crop overlay aspect ratio doesn't persist when resizing the crop overlay size.
I'd expected that setting an aspect ratio will enforce that the crop rectangle keeps the aspect ratio when resizing it.
Is this feature already implemented and I just missed it? 🤔
Some documentation would be nice

Material2 deprecated. Is there any possibility to migrate from Material2 to Material3?

I am trying to set the background color using CropDefaults.style(backgroundColor = Color.Red but looks like it is not working as expected.
I would expect the background color to be a color behind the image and overlayColor color to be a color that is semi-transparent that allows seeing the picture outside the crop box.

Thanks for lib. It's very useful. It would be nice to add free corner crop like in CamScanner.

I'm using Slider from 0 to 100, and wanted to be able to give the user the ability to adjust the cropping area using it

Issue from Issue #15 still persists. Same scenario. It can also be reproduced in demo.

Description

Current version of the library does not allow to zoom in lower scales than 1X, making usage of "overlay ratio" broken (especially, for static crop), because borders of crop cannot fill bounds of the picture

Current implementation

Required behaviour

Is it possible to remove the Offset in the Static crop type?

Thanks for this, it's just what I need! :)

I copied your ImageCropDemoSimple Composable and I am getting this error:

Any ideas?

I want to change the color of the black background in the photo.

I am interested in using this library, what is the reason for this library not yet occupying a stable version?

My question is similar to #4 but I need to solve it by adjusting the offset for a picture, not by removing the offset of an overlay. Is this possible?

It might look something like this:

Hey, can you expose cropping overlay with handles so it can be used for any composable component? It could be a modifier or compose component which takes content over which to draw.

For example, I want to implement video cropper, and I would like to wrap your cropper UI over the existing video surface, and would like to get the state of the cropper; width, height, startX & startY so I can proceed with video processing.

I am using your libraries without any issues.

However, I noticed that the cropping is not happening exactly where I want it.

For instance, I'm using your library to crop a part of a text and recognize the text.

But it doesn't crop exactly where I want, and I have to adjust it further down; otherwise, the text doesn't fully appear in the crop.

Do you know how I can solve this?

My code:

@Composable
internal fun ScreenShotCropImage(
    isCrop: Boolean,
    modifier: Modifier = Modifier,
    imageBitmap: ImageBitmap? = rememberImageBitmap(),
    onCropImageResult: (ImageBitmap?) -> Unit,
) {
    val handleSize: Float = LocalDensity.current.run { 20.dp.toPx() }

    val cropProperties by remember {
        mutableStateOf(
            CropDefaults.properties(
                contentScale = ContentScale.Inside,
                cropOutlineProperty = CropOutlineProperty(
                    OutlineType.Rect,
                    RectCropShape(0, "Rect"),
                ),
                aspectRatio = aspectRatios[3].aspectRatio,
                handleSize = handleSize,
                overlayRatio = 0.2f,
                maxZoom = 4f,
            ),
        )
    }
    val cropStyle by remember {
        mutableStateOf(
            CropDefaults.style(drawGrid = false, strokeWidth = 2.dp),
        )
    }

    imageBitmap?.let { image ->
        ImageCropper(
            modifier = modifier
                .fillMaxWidth(),
            imageBitmap = image,
            contentDescription = null,
            cropStyle = cropStyle,
            cropProperties = cropProperties,
            crop = isCrop,
            onCropStart = {},
            onCropSuccess = onCropImageResult,
        )
    }
}

Aspect ratio of cropped image is not exactly the one set in cropProperties.

Steps to reproduce in demo app:

1. Select 9:16 aspect ratio from settings.
2. Zoom image in or out. Don't change crop area
3. Cropp
4. Result image does not have 9/16 = 0.5625 aspect ratio, but something slightly different

Same behaviour is in static and dynamic mode
I did not successfully reproduce this for 1:1 aspect ratio.

Is there any way to avoid blank spaces?, that the drag limit is the image

Thanks!

Thank you for the great lib, it seems that there is no way to change the background color from black as it is hard-coded and not passed by the modifier.

Hi
Thank you for your good library
Is it possible to develop for compose multiplatform?
https://www.jetbrains.com/lp/compose-multiplatform/

Great library with great potential, but the lack of any documentation makes using it very difficult. I also see that it is probably no longer supported by the author.

Looks like there is a bug.
Steps to reproduce on Demo app:

1. Select a 9:16 ratio
2. Select an image from the gallery
3. Press crop without taking any actions

Actual: The image is not cropped properly
Expected: The image is cropped according to the area selected

I notice that if I move the image a little bit it crops properly, the issue happens only if the user selected the image and takes no action to adjust the crop area

Video of the bug
https://github.com/SmartToolFactory/Compose-Cropper/assets/11620779/a4bf603f-a9e2-49e4-8afe-c7b1ce1d15f7

Hi! Firstly thank you for great lib! It's very useful
Could you help me to figure out how I can rotate image or selection area and get rotated cropped image?

Hi
There isn't any image cropper library for compose multiplatform (jvm, android, ios, ...).
You created base of compose code and just need to change some code for compose multiplatform.
It will be very useful and i really need it.
Please work on it 🙏.

Edit: I found what is the problem. SmartToolFactory/Compose-Colorful-Sliders#12

I used to use the library without any problems. But right now I am getting an error like this. I tried downgrading and upgrading the Compose version but the result did not change. What could have caused it?

Is there any workaround that can be implemented to prevent this exception?

Currently there isn't a way to have different crop shape than the overlay cutout.
The use case would be when the overlay cutout represents the way the data is presented in the application rather than the way we actually want to crop the image.

I have read the code a bit and seems like a simple fix would be to provide a way to override the crop behaviour i.e a lambda in the api that receives the actually crop args and expects an ImageBitmap with default value equal to the current cropAgent.crop call.

Alternatively we can change the onCropStart to have this functionality.

What do you think?

If you approve the general approach I can do a PR and there we could iron out the details.

Hi! I just started exploring your library, and I find it great with many possible customizations!

But I have a question...

I would like to get the crop position and add a tooltip or tip on top. Is there a way for me to implement this?

Now it is only possible to drag corners, but it will be really helpful to add dragging for the sides of crop box too, like a 4 additional drag handles, which will be positioned at each edr of crop box

Thanks for lib. It's very useful.
It would be nice to add drawHandles flag to CropStyle to draw handles not only in dynamic crop.

Can you add free angle image rotation ?

When I don't drag the crop, for example, I select 1:1 square and then click crop directly, the resulting image is the original rectangle without the crop. If I move the image or crop box slightly, it works fine. demo can also reproduce this problem.

Issue:

When rendering full screen ImageCropper() over already full screen image, there is transition:

Request/suggestions:

• Let user define enter/exit animations (Will pollute ImageCropper params, it might be okay with default param?)
• Remove AnimatedVisibility and let user Animate the transition from parent composable (not sure how this would play out)

Hi
Please create this library to compose multiplatform.
there isn't any library to crop image for compose multiplatform.
