View 1 Replies View RelatedAndroid : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory
Jul 21, 2010I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?

BitmapFactory - (decode Returned False) For Internal Image Files Extracted From Zip
Apr 19, 2012Need to display images downloaded and extracted from a zip into the "/files" directory of the app. the images are getting in there properly as far as i can tell - i am able to extract them from the emulator and view/open them from my desktop. but every attempt, every variation of code i have found and tried so far has failed (Tag: skia / Text: --- decoder->decode returned false).
My latest construct, which does work for image files downloaded separately and uncompressed :
Code:
String imgFile = new File(getFilesDir(), "myImage.jpg").getAbsolutePath();
ImageView myImageView = new ImageView(this);
Bitmap bm = null;
try{
bm = BitmapFactory.decodeFile(imgFile);
myImageView.setImageBitmap(bm);
} finally{
mainLayout.addView(myImageView);
}
And here is the construct i am using to handle the zip extraction. I assume this is where the problem lies but i am clueless as to what i could possibly do differently and to what effect:
Code:
ZipInputStream zis = new ZipInputStream(fis);
BufferedInputStream in = new BufferedInputStream(zis, 8192);
ZipEntry ze;
while ((ze = zis.getNextEntry()) != null){
File dest_file = new File(getFilesDir(), ze.getName());

Android :: Resize Large Bitmap File To Scaled Output File
Jul 26, 2010I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file.I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of course exceed the memory (see here, for example).Is there a way to read a large image file with 10MP or more and save it to a new image file, resized to a specific new width and height, without getting an OutOfMemory exception?I also tried BitmapFactory.decodeFile(file, options) and setting the Options.outHeight and Options.outWidth values manually to 800 and 533, but it doesn't work that way.

Android :: How To Load Camera Image As Bitmap
Jun 1, 2010I am using BitmapFactory.decodeFile to load Bitmaps of images into my application. However, the function returns null on large images (such as those from the camera). The filepath is definitely correct, I just can't figure out why it would return null. I tried supersampling, but it didn't seem to help.
Does anyone have any idea why it would do this or how I could more easily load images taken from the camera into a Bitmap?

Android :: How Do I Make My Image View Fixed Size Regardless Of Size Of Bitmap
Sep 23, 2010So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file

Apr 2, 2009I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.
