为什么我的图像缩放不正确？
|
我正在尝试将图像缩放到一定大小，具体取决于发送到更新功能的水平大小，但是以下代码似乎无法正确调整图像大小。
编辑：代码：
public class GlassesView extends View {
private Paint paint;
private BitmapFactory.Options options;
private Bitmap bitmapOrg;
private Bitmap target;
private Bitmap bitmapRev;
private Bitmap resizedBitmap;
private int currY;
public int glassesX;
public int glassesY;
public float glassesSizeX;
public float glassesSizeY;
private boolean drawGlasses;
private boolean glassesMirrored;
public GlassesView(Context context) {
super(context);
paint = new Paint();
paint.setDither(false);
paint.setAntiAlias(false);
options = new BitmapFactory.Options();
options.inDither = false;
options.inScaled = false;
bitmapOrg = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(getResources(),
R.drawable.micro_glasses, options), 32, 5, false);
bitmapRev = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(getResources(),
R.drawable.glasses_reverse, options), 32, 5, false);
drawGlasses = false;
}
@Override
protected void onDraw(Canvas canvas) {
canvas.drawBitmap(target, 0, 0, paint);
boolean moving = currY < glassesY;
if (moving) {
currY++;
}
if (drawGlasses) {
int newWidth = resizedBitmap.getWidth();
int newHeight = resizedBitmap.getHeight();
Paint bluey = new Paint();
bluey.setColor(Color.argb(64, 0, 0, 255));
canvas.drawRect(new Rect(glassesX, currY, glassesX + newWidth,
currY + newHeight), bluey);
canvas.drawBitmap(resizedBitmap, glassesX, currY, paint);
}
if (moving) {
invalidate();
}
}
public void drawGlasses(int x1, int x2, int y, boolean mirror) {
drawGlasses = true;
glassesMirrored = mirror;
if (!mirror) {
glassesSizeX = (float) (x2 - x1) / (float) (25 - 16);
glassesSizeY = glassesSizeX;
glassesY = y - (int)(1*glassesSizeX);
glassesX = (int) (x1 - (glassesSizeX * 16));
} else {
glassesSizeX = (float) (x1 - x2) / (float) (25 - 16);
glassesSizeY = glassesSizeX;
glassesY = y - (int)(1*glassesSizeX);
glassesX = (int) (x1 - (glassesSizeX * 16));
}
currY = -1;
if (!glassesMirrored) {
resizedBitmap = Bitmap.createScaledBitmap(bitmapOrg,
(int) (bitmapOrg.getWidth() * glassesSizeX),
(int) (bitmapOrg.getHeight() * glassesSizeY), false);
} else {
resizedBitmap = Bitmap.createScaledBitmap(bitmapRev,
(int) (bitmapRev.getWidth() * glassesSizeX),
(int) (bitmapRev.getHeight() * glassesSizeY), false);
}
}
public void setTargetPic(Bitmap targetPic) {
target = targetPic;
}
}

Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, glassesWidth, glassesHeight, matrix, false);private void small() { int bmpWidth=bmp.getWidth(); int bmpHeight=bmp.getHeight(); Log.i(TAG, \"bmpWidth = \" + bmpWidth + \", bmpHeight = \" + bmpHeight); /* 设置图片缩小的比例 */ double scale=0.8; /* 计算出这次要缩小的比例 */ scaleWidth=(float) (scaleWidth*scale); scaleHeight=(float) (scaleHeight*scale); /* 产生reSize后的Bitmap对象 */ Matrix matrix = new Matrix(); matrix.postScale(scaleWidth, scaleHeight); Bitmap resizeBmp = Bitmap.createBitmap(bmp,0,0,bmpWidth, bmpHeight,matrix,true);俺呵誓放胳
