[問題] canvas 畫圖後 bitmap存檔解析度問題
private Bitmap generatorContactCountIcon(Bitmap icon)
{
Bitmap contactIcon=Bitmap.createBitmap(800, 480, Config.ARGB_8888);
Canvas canvas=new Canvas(contactIcon);
Paint iconPaint=new Paint();
iconPaint.setDither(true);
iconPaint.setFilterBitmap(true);
Rect src=new Rect(0, 0, icon.getWidth(), icon.getHeight());
Rect dst=new Rect(0, 0, 800, 480);
canvas.drawBitmap(icon, src, dst, iconPaint);
String contacyCount="ya";
Paint countPaint=
new Paint(Paint.ANTI_ALIAS_FLAG|Paint.DEV_KERN_TEXT_FLAG);
countPaint.setColor(Color.RED);
countPaint.setTextSize(20f);
countPaint.setTypeface(Typeface.DEFAULT_BOLD);
canvas.drawText(contacyCount, 100, 25, countPaint);
return contactIcon;
}
bitmap icon 是我原本的圖片，使用拍照得來
創建一個新的bitmap後，加上文字，想要回傳圖片時，
所得到的新的bitmap解析度卻很低，該如何挑整呢?
麻煩了
詢問了好久的 圖片加字 終於解決。
