BitmapFactory.Options inSampleSize calculating

SampleSize.java

public static int calculateInSampleSizeInside(BitmapFactory.Options options, int maxWidth, int maxHeight) {
		final int height = options.outHeight;
		final int width = options.outWidth;
		int inSampleSize = 1;
		
		if (height > maxHeight || width > maxWidth) {
			if (width > height) {
				inSampleSize = Math.round((float) height / (float) maxHeight);
			} else {
				inSampleSize = Math.round((float) width / (float) maxWidth);
			}
			
			if (height < maxHeight && width > maxWidth) {
				inSampleSize = Math.round((float) width / (float) maxWidth);
			}
			
			if (height > maxHeight && width < maxWidth) {
				inSampleSize = Math.round((float) height / (float) maxHeight);
			}
			
			if (inSampleSize == 1) {
				inSampleSize += 1;
			}
		}
		
		return inSampleSize;
	}

This doesnt work well, pic could be bigger than maxWidth/maxHeight

Math.ceil should apply

Works better:

public static int calculateInSampleSizeInside(int width, int height, int maxWidth, int maxHeight) {
    int inSampleSize = 1;

    int heightRatio = (int)Math.ceil((float)height/(float)maxHeight);
    int widthRatio = (int)Math.ceil((float)width/(float)maxWidth);

    if (heightRatio > 1 || widthRatio > 1)
    {
        if (heightRatio > widthRatio)
        {
            inSampleSize = heightRatio;
        } else {
            inSampleSize = widthRatio;
        }
    }
    return inSampleSize;
}
