ImageWidth プロパティ(ActiveX)

ラスター イメージの幅を指定します。

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.ImageWidth

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: 倍精度浮動小数点数型

ラスター イメージの幅

注意

このプロパティは Width プロパティに似ています。Width プロパティは、ピクセル単位のイメージ幅を指定します。このプロパティは、現在の単位のイメージ幅を指定します。

例

VBA:

Sub Example_ImageWidth()
    ' This example adds a raster image in model space and then finds
    ' the height and width of the image.
    
    ' This example uses the "2d Projected Polylines.jpg" found in the Sample
    ' directory. If you do not have this image, or if it is located
    ' in a different directory, insert a valid path and file name
    ' for the imageName variable below.
    
    Dim insertionPoint(0 To 2) As Double
    Dim scalefactor As Double
    Dim rotationAngle As Double
    Dim imageName As String
    Dim rasterObj As AcadRasterImage
    imageName = "C:/AutoCAD/sample/2d Projected Polylines.jpg"
    insertionPoint(0) = 5#: insertionPoint(1) = 5#: insertionPoint(2) = 0#
    scalefactor = 1#
    rotationAngle = 0
    
    ' Creates a raster image in model space
    Set rasterObj = ThisDrawing.ModelSpace.AddRaster(imageName, insertionPoint, scalefactor, rotationAngle)
    
    ' Find the height and width of the raster image
    Dim height As Variant
    Dim width As Variant
    
    height = rasterObj.ImageHeight
    width = rasterObj.ImageWidth
    
    MsgBox "Raster image: " & rasterObj.ImageFile & vbCrLf & _
            "ImageHeight: " & Str(height) & vbCrLf & _
            "ImageWidth: " & Str(width)
            
End Sub
