Windows phone 7 在wp7中调整图像大小

最近，我开始创建一个社交网络WP7应用程序。在发送用户数据的web请求时，它们在回调时为用户图像提供url。我的问题是，当绑定此图像时，我会得到不同大小的图像。很难保持图像大小一致。因此，用户界面看起来很普通。我需要做什么使这个图像大小一致。编写转换器或其他解决方案。谁能帮我解决这个问题。我尝试给出宽度、高度和填充属性，但仍然得到相同的结果

你可以试试这个：

WriteableBitmap resizedImage = new WriteableBitmap(imageToResize);//imageToResize is BitmapImage
using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
                {
                    using (System.IO.IsolatedStorage.IsolatedStorageFileStream isfs = new IsolatedStorageFileStream(fileName, FileMode.Create, isf))
                    {
                        double maxHeight = newWidth;
                        double maxWidth = newHeight;
                        double scaleX = 1;
                        double scaleY = 1;
                        if (pixHt > maxHeight)
                            scaleY = maxHeight / pixHt;
                        if (pixWt > maxWidth)
                            scaleX = maxWidth / pixWt;


                    double scale = Math.Min(scaleY, scaleX);
                    int newWidth1 = Convert.ToInt32(pixWt * scale);
                    int newHeight1 = Convert.ToInt32(pixHt * scale);

                    resizedImage.SaveJpeg(isfs, newWidth1, newHeight1, 0, 70);
                    isfs.Close();
                }
            }


您可以试试这个：


WriteableBitmap resizedImage = new WriteableBitmap(imageToResize);//imageToResize is BitmapImage
using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
                {
                    using (System.IO.IsolatedStorage.IsolatedStorageFileStream isfs = new IsolatedStorageFileStream(fileName, FileMode.Create, isf))
                    {
                        double maxHeight = newWidth;
                        double maxWidth = newHeight;
                        double scaleX = 1;
                        double scaleY = 1;
                        if (pixHt > maxHeight)
                            scaleY = maxHeight / pixHt;
                        if (pixWt > maxWidth)
                            scaleX = maxWidth / pixWt;


                    double scale = Math.Min(scaleY, scaleX);
                    int newWidth1 = Convert.ToInt32(pixWt * scale);
                    int newHeight1 = Convert.ToInt32(pixHt * scale);

                    resizedImage.SaveJpeg(isfs, newWidth1, newHeight1, 0, 70);
                    isfs.Close();
                }
            }
