ImageVisibility プロパティ(ActiveX)

イメージ表示のオン/オフを指定します。

サポートされているプラットフォーム: Windows のみ

構文と要素

VBA:

object.ImageVisibility

object

タイプ: GeomapImage、RasterImage、Wipeout

このプロパティが適用されるオブジェクト。

プロパティの値

読み込み専用: いいえ

タイプ: ブール型

• True: イメージを表示します。
• False: イメージを表示しません。

注意

作図セッション中にイメージを表示する必要がない場合は、イメージ表示をオフにすると再描画の速度を向上させることができます。非表示のイメージは、表示または印刷されず、図面の境界だけが表示されます。現在のビューポート座標系にかかわらず、イメージを非表示にすることができます。イメージが現在のビューポート座標系に対して直交でない(揃っていない)場合に特に有効です。

例

VBA:

Sub Example_ImageVisibility()
    ' This example inserts a raster image and finds the current status
    ' of ImageVisibility for the image. It then changes the ImageVisibility
    ' status of the image.
    
    ' This example uses the "2d Projected Polylines.jpg" found in the Sample
    ' directory. If you do not have the image, or if it is located
    ' in a different directory, insert a valid path and name for the
    ' imageName variable below.
    Dim insertionPoint(0 To 2) As Double
    Dim scalefactor As Double
    Dim rotAngleInDegree As Double, rotAngle As Double
    Dim imageName As String
    Dim raster As AcadRasterImage
    imageName = "C:\AutoCAD\sample\2d Projected Polylines.jpg"
    insertionPoint(0) = 2#: insertionPoint(1) = 2#: insertionPoint(2) = 0#
    scalefactor = 1#
    rotAngleInDegree = 0#
    rotAngle = rotAngleInDegree * 3.141592 / 180#
    
    On Error Resume Next
    
    ' Creates a raster image in model space
    Set raster = ThisDrawing.ModelSpace.AddRaster(imageName, insertionPoint, scalefactor, rotAngle)
    If Err.Description = "File error" Then
        MsgBox imageName & " could not be found."
        Exit Sub
    End If

    ' Find the current ImageVisibility
    ThisDrawing.Regen True
    MsgBox "The ImageVisibility is currently set to: " & raster.ImageVisibility, vbInformation
    
    ' Change the ImageVisibility
    If (raster.ImageVisibility) Then
        raster.ImageVisibility = False
    Else
        raster.ImageVisibility = True
    End If
    ThisDrawing.Regen True
    MsgBox "The ImageVisibility is now set to: " & raster.ImageVisibility, vbInformation
End Sub
