[英]vba control image transparency possible?
我的工作表中有一个要淡出的图像。 为此,我想找到一种为图像设置不同透明度阶段的方法,如下所示:
Set myPicture = ActiveSheet.Pictures.Insert(pic)
With myPicture
.Transparency = 0.5
Application.Wait (Now + TimeValue("00:00:01"))
.Transparency = 0.3
Application.Wait (Now + TimeValue("00:00:01"))
.Transparency = 0.1
Application.Wait (Now + TimeValue("00:00:01"))
.Delete
End With
目前我收到一条不支持对象的错误消息,这让我相信这可能是不可能的。
如果可能,请somoene 告诉我如何做到这一点? 谢谢
我花了很长时间才能DoEvents
工作(直到我尝试了DoEvents
)
Sub FadeInFadeOut()
Dim r As Range
Set r = Selection
ActiveSheet.Shapes("Rectangle 1").Select
Selection.ShapeRange.Fill.Transparency = 1
For i = 1 To 100
Selection.ShapeRange.Fill.Transparency = 1 - i / 100
DoEvents
Next
For i = 1 To 100
Selection.ShapeRange.Fill.Transparency = i / 100
DoEvents
Next
r.Select
End Sub
它适用于我在图纸上放置的自选图形。
注意:
您必须将100调整为淡入/淡出速度。
编辑#1:
这是一些垃圾代码(基于记录器),用于将自选图形放到图纸上并用图片填充:
Sub PicturePlacer()
Dim sh As Shape
ActiveSheet.Shapes.AddShape(msoShapeRectangle, 312.75, 176.25, 266.25, 129.75). _
Select
Selection.Name = "Sargon"
Application.CommandBars("AutoShapes").Visible = False
Range("G4").Select
ActiveCell.FormulaR1C1 = "123"
Range("G5").Select
ActiveSheet.Shapes("Sargon").Select
Selection.ShapeRange.Fill.Transparency = 0.56
Selection.ShapeRange.Line.Weight = 0.75
Selection.ShapeRange.Line.DashStyle = msoLineSolid
Selection.ShapeRange.Line.Style = msoLineSingle
Selection.ShapeRange.Line.Transparency = 0#
Selection.ShapeRange.Line.Visible = msoTrue
Selection.ShapeRange.Line.ForeColor.SchemeColor = 64
Selection.ShapeRange.Line.BackColor.RGB = RGB(255, 255, 255)
Selection.ShapeRange.Fill.Visible = msoTrue
Selection.ShapeRange.Fill.ForeColor.RGB = RGB(255, 255, 255)
Selection.ShapeRange.Fill.BackColor.RGB = RGB(255, 255, 255)
Selection.ShapeRange.Fill.UserPicture "C:\Users\garys\Pictures\babies.jpeg"
End Sub
记住要命名形状,并在所有引用该形状的代码中使用该名称。
上周我刚刚遇到了这个出色的例程并尝试了它。 我注意到的唯一缺点是因为形状被选中,当 For ... Next 循环运行时,选择手柄在形状上可见。 我也看到了Princess.Bell 贴的问题:“有没有办法给形状添加背景图片?” 我对这篇文章有一个更新,它解决了这两个问题。 我还通过将 For ... Next 循环中的“计时器”从 100 调整到 250 来减缓淡入和淡出。这允许淡入和淡出过程发生在 0.5 秒以上。
Sub FadeInFadeOut()
Dim shp As Shape
Set shp = Sheets("Sheet1").Shapes.AddShape(Type:=msoShapeRectangle, _
Left:=35, Top:=117, Width:=72.75, Height:=25.5)
Dim i As Integer
With shp.Fill
.Visible = msoTrue
.UserPicture FileName '==> C:\Users\Me\AppData\Local\Temp\SavedImage.jpg (image file)
For i = 1 To 250 'Fade in shape/picture.
.Transparency = 1 - i / 250
DoEvents
Next
For i = 1 To 250 'Fade out shape/picture.
.Transparency = i / 250
DoEvents
Next
End With
shp.Delete 'Discard the shape now that we're done using it.
Range("C3").Select 'Position cursor.
