Question

如何缩放图像 - 无论是使用Bitmap还是EncodedImage来填充字段的整个宽度和高度？

试过这个：

protected void paintBackground(Graphics g) {
    super.paintBackground(g);
     //try bitmap
     //g.drawBitmap(0, 0, this.getWidth(), this.getHeight(), image 0, 0);
     //try encoded image
     g.drawImage(0, 0, this.getContentWidth(), this.getContentHeight(), image, 0, 0, 0);

}

此处询问此问题是链接Blackberry - how to resize image?

在OS 5.0中，api scaleInto方法在Bitmap类中提供，即 http://www.blackberry.com/developers/docs/5.0.0api/net/rim/device/api/system/Bitmap.html#scaleInto%28net.rim.device.api.system.Bitmap,%20int%29

对于OS 5.0以下，这篇bb kb文章将有助于图像处理 http://supportforums.blackberry.com/t5/Java-Development/Rotate-and-scale-bitmaps/ta-p/492524
