一、旋转翻转过滤器：旋转图片

Dim Img 'As ImageFile
Dim IP 'As ImageProcess

Set Img = CreateObject("WIA.ImageFile")
Set IP = CreateObject("WIA.ImageProcess")

Img.LoadFile "C:\WINDOWS\Web\Wallpaper\Bliss.bmp"

IP.Filters.Add IP.FilterInfos("RotateFlip").FilterID
IP.Filters(1).Properties("RotationAngle") = 90

Set Img = IP.Apply(Img)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\Bliss90.bmp"

二、裁剪滤镜：裁剪图片

Dim Img 'As ImageFile
Dim IP 'As ImageProcess

Set Img = CreateObject("WIA.ImageFile")
Set IP = CreateObject("WIA.ImageProcess")

Img.LoadFile "C:\WINDOWS\Web\Wallpaper\Bliss.bmp"

IP.Filters.Add IP.FilterInfos("Crop").FilterID
IP.Filters(1).Properties("Left") = Img.Width \ 4
IP.Filters(1).Properties("Top") = Img.Height \ 4
IP.Filters(1).Properties("Right") = Img.Width \ 4
IP.Filters(1).Properties("Bottom") = Img.Height \ 4

Set Img = IP.Apply(Img)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\BlissCrop.bmp"

 

三、缩放滤镜：调整图像的大小

Dim Img 'As ImageFile
Dim IP 'As ImageProcess

Set Img = CreateObject("WIA.ImageFile")
Set IP = CreateObject("WIA.ImageProcess")

Img.LoadFile "C:\WINDOWS\Web\Wallpaper\Bliss.bmp"

IP.Filters.Add IP.FilterInfos("Scale").FilterID
IP.Filters(1).Properties("MaximumWidth") = 100
IP.Filters(1).Properties("MaximumHeight") = 100

Set Img = IP.Apply(Img)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\BlissThumb.bmp"

 

四、邮票过滤器：邮票在另一个图片一个图片

Dim Thumb 'As ImageFile
Dim Img 'As ImageFile
Dim IP 'As ImageProcess

Set Img = CreateObject("WIA.ImageFile")
Set Thumb = CreateObject("WIA.ImageFile")
Set IP = CreateObject("WIA.ImageProcess")

Img.LoadFile "C:\WINDOWS\Web\Wallpaper\Bliss.bmp"
Thumb.LoadFile "C:\WINDOWS\Web\Wallpaper\BlissThumb.bmp"

IP.Filters.Add IP.FilterInfos("Stamp").FilterID
Set IP.Filters(1).Properties("ImageFile") = Thumb
IP.Filters(1).Properties("Left") = Img.Width - Thumb.Width
IP.Filters(1).Properties("Top") = Img.Height - Thumb.Height

Set Img = IP.Apply(Img)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\BlissStamp.bmp"

 

五、EXIF过滤器：写一个新的标题标签图像

Dim Img 'As ImageFile
Dim IP 'As ImageProcess
Dim v 'As Vector

Set Img = CreateObject("WIA.ImageFile")
Set IP = CreateObject("WIA.ImageProcess")
Set v = CreateObject("WIA.Vector")

Img.LoadFile "C:\WINDOWS\Web\Wallpaper\Autumn.jpg"

IP.Filters.Add IP.FilterInfos("Exif").FilterID
IP.Filters(1).Properties("ID") = 40091
IP.Filters(1).Properties("Type") = VectorOfBytesImagePropertyType '此处的VectorOfBytesImagePropertyType值应改为：1101

v.SetFromString "This Title tag written by Windows Image Acquisition Library v2.0"

IP.Filters(1).Properties("Value") = v

Set Img = IP.Apply(Img)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\AutumnExif.jpg"

六、帧过滤器：创建一个多页TIFF三种图片

Dim Img 'As ImageFile
Dim Page2 'As ImageFile
Dim Page3 'As ImageFile
Dim IP 'As ImageProcess
Dim v 'As Vector

Set Img = CreateObject("WIA.ImageFile")
Set Page2 = CreateObject("WIA.ImageFile")
Set Page3 = CreateObject("WIA.ImageFile")
Set IP = CreateObject("WIA.ImageProcess")

Img.LoadFile "C:\WINDOWS\Web\Wallpaper\Bliss.bmp"
Page2.LoadFile "C:\WINDOWS\Web\Wallpaper\Azul.jpg"
Page3.LoadFile "C:\WINDOWS\Web\Wallpaper\Autumn.jpg"

IP.Filters.Add IP.FilterInfos("Frame").FilterID
Set IP.Filters(IP.Filters.Count).Properties("ImageFile") = Page2

IP.Filters.Add IP.FilterInfos("Frame").FilterID
Set IP.Filters(IP.Filters.Count).Properties("ImageFile") = Page3

IP.Filters.Add IP.FilterInfos("Convert").FilterID
IP.Filters(IP.Filters.Count).Properties("FormatID") = wiaFormatTIFF

Set Img = IP.Apply(Img)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\Bliss.tif"

Img.ActiveFrame = Img.FrameCount

Set v = Img.ARGBData

Set Img = v.ImageFile(Img.Width, Img.Height)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\Autumn.bmp"

 

 

七、ARGB过滤器：创建一个修改版本的图片

Dim Img 'As ImageFile
Dim IP 'As ImageProcess
Dim v 'As Vector
Dim i 'As Long

Set Img = CreateObject("WIA.ImageFile")
Set IP = CreateObject("WIA.ImageProcess")

Img.LoadFile "C:\WINDOWS\Web\Wallpaper\Bliss.bmp"

Set v = Img.ARGBData

For i = 1 To v.Count Step 21
v(i) = &HFFFF00FF 'opaque pink (A=255,R=255,G=0,B=255)
Next

IP.Filters.Add IP.FilterInfos("ARGB").FilterID
Set IP.Filters(1).Properties("ARGBData") = v

Set Img = IP.Apply(Img)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\BlissARGB.bmp"

 

八、从另一个文件转换过滤器：创建一个压缩的JPEG文件

Dim Img 'As ImageFile
Dim IP 'As ImageProcess

Set Img = CreateObject("WIA.ImageFile")
Set IP = CreateObject("WIA.ImageProcess")

Img.LoadFile "C:\WINDOWS\Web\Wallpaper\Bliss.bmp"

IP.Filters.Add IP.FilterInfos("Convert").FilterID
IP.Filters(1).Properties("FormatID").Value = wiaFormatJPEG
IP.Filters(1).Properties("Quality").Value = 5

Set Img = IP.Apply(Img)

Img.SaveFile "C:\WINDOWS\Web\Wallpaper\BlissCompressed.jpg"
