Android的 - 保存的ImageView与全分辨率图像到文件 [英] Android - Save ImageView to file with full resolution image

问题描述

我把图像的ImageView的内部，已经实现多点触控来调整大小和移动的ImageView内的图像。现在，我需要将调整后的图像保存为图像文件。我曾尝试.getDrawingCache（），但图像有ImageView的大小。我想要的图像显示的是什么节目的ImageView但全分辨率（比ImageView的大）。

I put an image inside an ImageView and have multitouch implemented to resize and move the image inside the ImageView. Now I need to save the resized image to a image file. I have tried the .getDrawingCache() but that image have the size of the ImageView. I want the image to show what the ImageView shows but with full resolution (larger than the ImageView).

任何想法？

推荐答案

我的解决办法是使用我用于ImageView的得到转换矩阵，我也有这样的图像的规模。使用这些两个I裁剪的原始图像

My solution was to use the matrix that I used for the ImageView to get the translation and I also had the scale of that image. Using those two I cropped the original image.

Bitmap resizedBitmap = Bitmap.createBitmap(
                        BitmapFrontCover, (int) UpperLeftCornerX,
                        (int) UpperLeftCornerY, (int) CropWidth,
                        (int) CropHeight);
