java - How to fix cutted/trimmed side on canvas/bitmap?

Question

Im trying to merge to bitmap using this code

Bitmap bitmapMerged = Bitmap.createBitmap(
            w, h,
            bitmapOriginal.getConfig()); 
            Canvas canvasMerged = new Canvas(bitmapMerged);
            canvasMerged.drawBitmap(bitmapOriginal, 0, 0, null);
            canvasMerged.drawBitmap(bitmapSecond, bitmapOriginal.getWidth(), 0, null);
            

It merge successfully, my next goal is to rotate the merged bitmap so I used this code

Matrix matrix = new Matrix(); 
             matrix.postRotate(10); 
             canvasMerged.setMatrix(matrix);

But the image is cutted/trim the side it seems it didnt fit in how to fix this?

Answer 1

Use matrix.postRotate(); with center. So,

matrix.postRotate( 10, centerX, centerY );
