ImageProcess Object

زنجیره فیلتر را مدیریت می کند. یک شی ImageProcess را می توان با استفاده از "WIA.ImageProcess" به عنوان ProgID در فراخوانی به CreatObject ایجاد کرد.

مثال Image Resize

Dim Thumb 'As ImageFile
Dim Img 'As ImageFile

Dim IP 'As ImageProcess
"Img ="WIA.ImageFile
"IP ="WIA.ImageProcess
"Thump="WIA.ImageFile

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

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

Set Img = IP.Apply(Img)

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

---------------------

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

------------------

IP.Filters.Add IP.FilterInfos("Crop").FilterID

4/IP.Filters(1).Properties("Left") = Img.Width

4/IP.Filters(1).Properties("Top") = Img.Height

 IP.Filters(1).Properties("Right") = Img.Width/ 4

 IP.Filters(1).Properties("Bottom") = Img.Height / 4

FilterInfos Object

شامل مجموعه ای از همه اشیاء FilterInfo موجود است. برای جزئیات بیشتر در مورد دسترسی به شی FilterInfos ، از ویژگی FilterInfos (ImageProcess) در شی ImageProcess دیدن کنید.

To get further documentation for ImageProcess, we can just "ask it"! Run this:
()Sub List_WIA_ImageProcess_Filters
    Dim f As Object, x As Long
    For Each f In CreateObject("WIA.ImageProcess").FilterInfos
        x = x + 1
        Debug.Print "#" &x &": " &f.Name &" = " &f.Description &vbLf
    Next f
End Sub
