我试图获取视图的屏幕截图如下.我正在获取Bitmap,我需要将其转换为
Image以添加到PDF生成器中.
using (var screenshot = Bitmap.CreateBitmap(200,100,Bitmap.Config.Argb8888))
{
var canvas = new Canvas(screenshot);
rootView.Draw(canvas);
using (var screenshotOutputStream = new FileStream(screenshotPath,System.IO.FileMode.Create))
{
screenshot.Compress(Android.Graphics.Bitmap.CompressFormat.Png,90,screenshotOutputStream);
screenshotOutputStream.Flush();
screenshotOutputStream.Close();
}
}
我的问题是如何将Android.Graphics.Bitmap – >截图转换为Image？
我想用来自BitMap的Image本身替换url.
String imageUrl = "myURL"; Image image = Image.GetInstance (new Uri (imageUrl)); document.Add(image);
解决方法
您可以使用此方法：
public Bitmap getScreenshotBmp() {
FileOutputStream fileOutputStream = null;
File path = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
String uniqueID = UUID.randomUUID().toString();
File file = new File(path,uniqueID + ".jpg");
try {
fileOutputStream = new FileOutputStream(file);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
screenshot.compress(Bitmap.CompressFormat.JPEG,30,fileOutputStream);
try {
fileOutputStream.flush();
fileOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
return screenshot;
}
