Implementation for custom image cropping in Android - android

I need to implement the custom image cropping instead of using the system cropping (i.e. "com.android.camera.action.CROP"). I need to know the exact position of the cropping bounding box but this information is not retrievable if I choose to use the default cropping. Besides, the bitmap image is down sampled too much by default cropping.
The steps are as following:
Create the original size bitmap from source (using uri). The
original size is about 4000x3000 which is too big.
The user defines the crop area to extract the ROI which results in resizing of the original image to fit the ImageView. (size of ImageView is about 700x700)
Record the position of the bounding box in the ImageView.
Retrieve the cropped area from the original image and create another bitmap for it.
Resize the cropped bitmap to fit the imageview size to show it on the screen.
This approach works on my device (ZTE nuoio with Android 4.3) well. However, the app crashes on Samsung S4 with Android 4.4.4 and Note 4 while performing step 1 probably because of the out-of-memory error.
Therefore, I try to do another approach that creates the bitmap which is down sampled from the source image, rather than having the original size bitmap image.
I need to have the information of the exact position of cropped area from the original image. That is the reason why I didn't use default cropping. Could you please help me out with my case either providing
the solutions to derive the exact coordinates of the bounding box of the cropped image in the original image as a matrix.
how to solve the out-of-memory error in step 1 using the approach I mentioned above.
Or other approach to achieve image cropping with knowing the exact coordinates of cropped area form the original image.
Thank you so much.

For Crop an image and get Coordinates use library Edmodo Croper https://github.com/edmodo/cropper
For Out of memory issue you have to down scale image.

ImageView bitmap is stretched after activity transition

Is there any specific reason why this is happening?
This is the image after the transition happens.
You haven't provided any code to help us diagnose your problem, but your terrifying image (that looks like Jim Carrey) may be related to the tileMode. Your image looks like it's exhibiting clamping.
Clamping is when the edge color is replicated if the bitmap for an ImageView is smaller in size than the ImageView. These are all the options, along with a suitable picture of Jim:
disabled - Do not tile the bitmap. This is the default value.
clamp - Replicates the edge color.
repeat - Repeats the bitmap in both direction.
mirror - Repeats the shader's image horizontally and vertically, alternating mirror images so that adjacent images always seam.
Since it looks like your Bitmap is smaller than your ImageView and I don't think you actually want to use any tile mode (just use the default of disabled), I'd recommend either:
A) Use ImageView's setScaleType() so that the Bitmap resizes to fill the ImageView, using the centerCrop value (though check this blog for more examples), or...
B) Make your Bitmap larger
(I'd recommend A)

Resize an image to square resolution

I am developing an android application which resizes android pictures. I was wondering if its possible to resize a file with resolution (1080X1920) to (500X500) square size.
Without looking too bad (quality and dimensions).
Let me show you an example.
First image:
Resized picture:
Answers using code will be appreciated
If you don't want to distort the image you have two options:
Crop the image
Implement the seam carving algorithm
Edit: this assumes you want to fill up the whole square. If not, just keep the width/height ratio and downscale the image properly so that the largest dimension fits in the side of the square.

Crop an image, only visible part of it, which is behind another image

I want to get the part of an image which is visible to us. There is another image over the first image. So from that image, some part of first image is visible. And I want that part only.
I’ll show you sample of it and final output which I am expecting from it.
I know how to crop in oval shape. But here, the template used in above example can be different in actual, so as per the template /mask I need to crop that image.
How can I do this. Any idea?
A simple but maybe not very efficient solution:
assume the mask is above the real image
both images are in the same container and if the mask is above the image this means that the pixels of the image would correspond to pixels of the mask
draw only those pixels of the image whose corresponding pixel in the mask is not black

Android imageview image quality matter?

I am writing a Android app which need to display some high quality picture(took from professional DSLR). The problem is it can't be display from gallery.
I choose a photo in Gallery first. The target picture is 2464*1632 JPEG, roughly 4.5M;
Then I just need to compress it to 800*600 and display it in imageview:
image.setImageBitmap(this.bmp);
Thing is that I have tested other image I downloaded form internet(really low quality), and it works without any problem. Can anybody tell me why it can't be displayed? I will be really appericiated
Large images are tricky to handle due to limited memory. You have several choices:
Use a WebView (this allows you to have pinch and zoom functionality to make use of those extra pixels
Decode the image down to the size of the display and then put it in an ImageView using BitmapOpts http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html and changing inSampleSize. It seems you may be having difficulty with that, so consider using createScaledBitmap which just needs the dest width and height.

Android: Resample bitmap as zooming in?

I have some large images that I would like to display to the user. I want them to have the ability to zoom in. I am currently using TouchImageView, and it is working, however, the quality/resolution of the image does not change as I zoom in.
I noticed that some of the Gallery apps appear to be doing this. They load the entire image, at some sampling rate so that it can be displayed without an out of memory. Then as you zoom in, it appears that the quality of the image is getting increased.
Is there example code/library for functionality similar to this?
If you have 1 source image and are zooming in on it you aren't going to magically create resolution where there was none previously. The answer is to either create multiple r-sets or multiple images with different resolutions and load/zoom/scale dynamically, OR downsample the image yourself when displaying it zoomed out at a lower resolution.
For example, consider thumbnail images. They are created as a small sample of the original image. If you zoomed in on that thumbnail it would look horrible. You calculate the best r-set image based on the zoom level and coordinates of your client view.
I think my preference would be to preprocess the large images and create different levels of resolution as I mentioned in the first paragraph. Then as the user zooms in you load a different image. This is similar to how Google maps works for example.
I hope this helps.
I suggest that you use the view provided by Dave Morrissey:
Subsampling Scale Image View
An excerpt from the source:
A custom ImageView for Android with pinch to zoom and subsampled tiles
to support large images. While zooming in, the low resolution, full
size base layer is overlaid with smaller tiles in the best resolution
for the current scale, and tiles are loaded and discarded during
panning to avoid holding too much bitmap data in memory.
