尝试一下,计算比例,然后重新缩放.
Try this, calculate the ratio and then rescale.
private Bitmap scaleBitmap(Bitmap bm) {
int width = bm.getWidth();
int height = bm.getHeight();
Log.v("Pictures", "Width and height are " + width + "--" + height);
if (width > height) {
// landscape
float ratio = (float) width / maxWidth;
width = maxWidth;
height = (int)(height / ratio);
} else if (height > width) {
// portrait
float ratio = (float) height / maxHeight;
height = maxHeight;
width = (int)(width / ratio);
} else {
// square
height = maxHeight;
width = maxWidth;
}
Log.v("Pictures", "after scaling Width and height are " + width + "--" + height);
bm = Bitmap.createScaledBitmap(bm, width, height, true);
return bm;
}
