function tryDisplayStorageFileBitmapAtCursorAsync(bitmap, horizontalAlignment, verticalAlignment, widthInPixels)

Public Function TryDisplayStorageFileBitmapAtCursorAsync (bitmap As StorageFile, horizontalAlignment As LineDisplayHorizontalAlignment, verticalAlignment As LineDisplayVerticalAlignment, widthInPixels As Integer) As IAsyncOperation(Of Boolean)

参数

bitmap

StorageFile

要显示的位图。

horizontalAlignment

LineDisplayHorizontalAlignment

位图相对于当前文本字符位置的水平对齐方式。

verticalAlignment

LineDisplayVerticalAlignment

位图相对于当前文本字符位置的垂直对齐方式。

widthInPixels

Int32

int

位图所需的宽度。 如果值为 0 像素，则每个屏幕点 (未缩放) 显示一个像素的位图。

返回

IAsyncOperation<Boolean>

IAsyncOperation<bool>

如果成功显示位图，则返回 True;否则为 False。

属性

OverloadAttribute RemoteAsyncAttribute

Windows 要求

设备系列	Windows 10 Fall Creators Update (在 10.0.16299.0 中引入)
API contract	Windows.Foundation.UniversalApiContract (在 v5.0 中引入)

注解

如果 LineDisplayCapabilities.CanDisplayBitmaps 值为 False，则此方法将失败。

如果提供的 widthInPixels 值大于 ClaimedLineDisplay.MaxBitmapSizeInPixels，则此方法将失败。
