TiffBitmapFactory is an Android library that allow open *.tif(See Wikipedia) image files on Android devices.
For decoding *.tif files it uses native library libtiff
Just now it has possibility to open tif image as mutable bitmap, read count of directory in file, apply sample rate for bitmap decoding and choose directory to decode.
File file = new File("sdcard/image.tif");
//Read data about image to Options object
TiffBitmapFactory.Options options = new TiffBitmapFactory.Options();
options.inJustDecodeBounds = true;
TiffBitmapFactory.decodeFile(file, options);
int dirCount = options.outDirectoryCount;
int width = options.outWidth;
int height = options.outHeight;
//Change sample size if width or height bigger than required width or height
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
//Set calculated parameters to Options object
options.inJustDecodeBounds = false;
options.inSampleSize = inSampleSize;
//Set last directory of image to decode
options.inDirectoryCount = dirCount;
//Decode bitmap
Bitmap bmp = TiffBitmapFactory.decodeFile(file, options);To build native part of library use Android-NDK-bundle-10 or higher.
