拍攝的圖像在Android中裁剪後延伸錯誤

Question

我想從我的相機捕捉圖像並在指定的座標下裁剪捕捉的圖像然後在另一幅圖像的中間繪製它。以下代碼不會崩潰，但由於圖像拉伸錯誤，所捕獲的圖像被擰緊，。

我哪裏錯了？

Merry X'mas！

//Get the bottom image Bitmap 

Bitmap bottomImage = BitmapFactory.decodeResource(getResources(), SelectDollarActivity.selectedImageId); 

//Get the captured image Bitmap 

Bitmap capturedImage = BitmapFactory.decodeFile(CaptureImage.cImagePath) ; 

//************ CROP THE CAPTURED IMAGE ******************* 


int targetBitmapWidth = bottomImage.getWidth();  
int targetBitmapHeight = bottomImage.getHeight() ;  

//create a Bitmap with specified width & height 

Bitmap clippedBitmap = Bitmap.createBitmap(targetBitmapWidth, targetBitmapHeight, Bitmap.Config.ARGB_8888); 

//Construct a canvas with the specified bitmap to draw into. 

Canvas canvas = new Canvas(clippedBitmap); 

//************** cropping process goes HERE......... 

//Create a new rectangle with the specified coordinates 

RectF rectf = new RectF(left, top, right, bottom); 

//Create an empty path 

Path path = new Path(); 

//Add a closed oval contour to the path 

path.addOval(rectf, Path.Direction.CW); 

//Intersect the current clip with the specified path : CROPPING 

canvas.clipPath(path); 

canvas.drawBitmap(capturedImage, null, new Rect(0, 0, targetBitmapWidth, targetBitmapHeight), null); 

    //******** MERGING PROCESS *******************   

//Construct a canvas with the specified bitmap to draw into. 

Canvas combo = new Canvas(bottomImage); 

// Then draw the second on top of that 

combo.drawBitmap(clippedBitmap, 0f, 0f, null); 

// bottomImage is now a composite of the two. so, display the bottom image  


//************** DISPLAY THE MERGED IMAGE **************** 

((ImageView)findViewById(R.id.billImage)).setImageBitmap(bottomImage);

Documentation指出drawBitmap接受兩個更多的參數，寬度和高度。在您的代碼中，

combo.drawBitmap(clippedBitmap, 0f, 0f, null); 

只有定位。

您將需要設置更多的參數當然，但它應該工作：D
