What is Android ImageResizer?

Simple library which provides Bitmap (in form of File, byte[] and Resource) resizing, cropping, rotation, flipping on Android. Used tips from developer.android.com.

Resize

// Different width and height
ImageResizer.resize(myImageFile, 640, 480);
    
// Choose ResizeMode - FIT_TO_WIDTH, FIT_TO_HEIGHT, FIT_EXACT or AUTOMATIC
ImageResizer.resize(myImageFile, 640, 480, ResizeMode.FIT_TO_WIDTH);

Crop

// Basic croping
ImageResizer.crop(myImageFile, 500, 500);

// Croping with specified starting X and Y point
ImageResizer.crop(myImageFile, 50, 50, 640, 480);

Rotation and flipping

Very memory-intensive for high-resolution images (for ex. 2560*1600), better scale it down and then rotate.

// Rotate an image for 90, 180 or 270 degrees
ImageResizer.rotate(myImageFile, ImageRotation.CW_90);

// Flip an image horizontally or vertically
ImageResizer.rotate(myImageFile, ImageRotation.FLIP_HORIZONTAL);
