In apps like NoCrop an image is made to fit a resolution of 1:1 (made square) by adding some extra spaces at the top and bottom of the image (shown below).
Similarly, I wish to add some spaces to an image through my Android app, to fit a resolution of ratio, say 16:9. My app creates a video by stitching these images together, and for the video, all the images first need to be converted into a fixed resolution.
I have not used Bitmaps much, nor I am an expert in Android. Any kind of help would be appreciated! :)
Try adding these to your ImageView in xml:
android:scaleType="centerCrop"
android:adjustViewBounds="true"
This will crop your image so that it fits the ImageView

I have png images that have drop shadow. There is no unproportional images scaling problem, scaling are according to the aspect ratio.
When I using Image.asset() for placing images on phone screen, they're and their shadows looks low quality and not soft.
Original image looks: http://prnt.sc/p93vo2
Image on Android App: https://prnt.sc/p93vz3
Example images are same and 700x400, 96dpi.
You should see quality difference between images.
There is also a strange stuation. The shadow density on right and bottom side is more than shadow of original image on android app.
I've tried FilterQuality.high but no change, how to fix it?
In my case, the problem was due to a bad configuration of the image resolution system.

I have a problem with image size and resolution on my app I need to upload an image then I want to resize it to all screen, which is the best image size and width/height for banner and logo and I need a good tool that resizes image?
You will want to remake the logo in a vector format, this relies on positions rather than individual pixels.
In other words no matter how big you make the image, it will always be crisp and sharp.
If I remember to back when I dabbled in Android development I seem to remember android making different sized versions of the logo and banner... Therefore what I would do is create the logo in a vector program such as Inkscape or Adobe Illustrator, and exporting it as a high quality png, this way if you need to resize it in the future, you just export it at a different size and you're good to go.
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.

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.
I know that ,according to android docs, that if you have a big image. Then you scale it down to size of the image view you are loading it to (using the decodeResources and Options class).
Now my question is, lets say you want to load background picture and the source image is of similar size, do you just load the image? Or do you actually scale it down a bit and then using the FITXY to stretch it?
I am trying to avoid Out Of Memory exceptions here
Thank you
I have to make my app capable of taking pictures of only whatever it fits a squared frame that is superimposed on the preview.
The idea is: the client wants the app to send pictures of 600x600px tops. To avoid cropping important parts of the picture, he decided to put this superimposed squared frame (similar to the one in QR-reading apps) and to crop out everything out of said frame.
To do this I need two things.
1) How do I set the frame dimensions for multiple screens while getting the output within the required dimensions?
2) Once the frame is up and running... how do I crop out the rest of the picture?
Thanks in advance.
Update
What I want to do is something similar to what is explained here http://www.londatiga.net/featured-articles/how-to-select-and-crop-image-on-android/
Thing is:
This how-to checks if there's an image-cropper app installed, it
doesn't do the cropping by itself (or so I understand, maybe I'm
wrong?).
The frame seems to be 200x200... px? dp? Would that frame take up the
same portion of screen on xhdpi screens that on ldpi screens?
What's the size of the resulting image? Can I decide it somehow?
