getInSampleSize

public int getInSampleSize(ImageTask imageTask)

Description copied from interface: ImageReSizer

Return the BitmapFactory.Options#inSampleSize, which will be used when load the image from the disk.

You should better calculate this value according the hard device of the mobile.

Specified by:

getInSampleSize in interface ImageReSizer

getRemoteUrl

public java.lang.String getRemoteUrl(ImageTask imageTask)

calculateInSampleSize

public static int calculateInSampleSize(int originWidth,
                        int originHeight,
                        int reqWidth,
                        int reqHeight)

Calculate an inSampleSize for use in a BitmapFactory.Options object when decoding bitmaps using the decode* methods from BitmapFactory.

This implementation calculates the closest inSampleSize that is a times of 2 and will result in the final decoded bitmap having a width and height equal to or larger than the requested width and height.
