function tryDisplayStorageFileBitmapAtPointAsync(bitmap, offsetInPixels)

Public Function TryDisplayStorageFileBitmapAtPointAsync (bitmap As StorageFile, offsetInPixels As Point) As IAsyncOperation(Of Boolean)

參數

bitmap

StorageFile

要顯示的點陣圖。

offsetInPixels

Point

要從螢幕左上角位移點陣圖顯示的圖元數目。 {0,0}

傳回

IAsyncOperation<Boolean>

IAsyncOperation<bool>

如果已成功顯示點陣圖，則傳回 True;否則為 False。

屬性

OverloadAttribute RemoteAsyncAttribute

Windows 需求

裝置系列	Windows 10 Fall Creators Update (已於 10.0.16299.0 引進)
API contract	Windows.Foundation.UniversalApiContract (已於 v5.0 引進)

備註

如果 LineDisplayCapabilities.CanDisplayBitmaps 值為 False，這個方法將會失敗。

TryDisplayStorageFileBitmapAtPointAsync(StorageFile, Point, Int32)

嘗試在特定時間點以非同步方式顯示儲存體檔案中的點陣圖，並調整為特定寬度。

function tryDisplayStorageFileBitmapAtPointAsync(bitmap, offsetInPixels, widthInPixels)

Public Function TryDisplayStorageFileBitmapAtPointAsync (bitmap As StorageFile, offsetInPixels As Point, widthInPixels As Integer) As IAsyncOperation(Of Boolean)

參數

bitmap

StorageFile

要顯示的點陣圖。

offsetInPixels

Point

要從螢幕左上角位移點陣圖顯示的圖元數目。 {0,0}

widthInPixels

Int32

int

所需的點陣圖寬度。 值為 0 圖元會在每個螢幕點顯示一個圖元的點陣圖， (未調整的) 。

傳回

IAsyncOperation<Boolean>

IAsyncOperation<bool>

如果已成功顯示點陣圖，則傳回 True;否則為 False。

備註

如果 LineDisplayCapabilities.CanDisplayBitmaps 值為 False，這個方法將會失敗。

如果提供的 widthInPixels 值大於 ClaimedLineDisplay.MaxBitmapSizeInPixels，這個方法將會失敗。
