Include thumbnail in custom table

[Anonymous]

I am using iLogic to create an HTML page with a table listing certain parts from an assembly BOM.

I would like to include a column for a thumbnail image of the part. Here is some of the code (please note, large chunks of code is missing, but just to give a better idea of what I'm building on)

oWrite = System.IO.File.CreateText(oHTMLDoc)	' Create the HTML file
' Lines to set up HTML table, fonts etc.....

For Each oRow As BOMRow In oBOMRows
        oRowCompDef = oRow.ComponentDefinitions.Item(1)
	fullfilename = oRowCompDef.Document.FullFileName
	partnumber = oRowCompDef.Document.PropertySets("Design Tracking Properties").Item("Part Number").Value
	category = oRowCompDef.Document.PropertySets("Inventor Document Summary Information").Item("Category").Value
	comments = oRowCompDef.Document.PropertySets("Inventor Summary Information").Item("Comments").Value

	' Add thumbnail image here
	oWrite.WriteLine("<td Class=""tg-yw4l"">" & "<a href=""" & fullfilename & """> " & partnumber & "</a>" & "</td>")
	oWrite.WriteLine("<td Class=""tg-yw4l"">" & category & "</td>")
	oWrite.WriteLine("<td Class=""tg-yw4l"">" & comments & "</td>")
Next

 What is the best way to access the thumbnail image for me to use it on my HTML document?

I am able to get the thumbnail iProperty as IPictureDisp but I need a way to convert & save this as an image for me to use on my page. Can anyone provide some guidance how to achieve this?

You could create a image on saving the document, and use that..

I mean export ie *.bmp

Do you have some sample code?

[bradeneuropeArthur]

Public Sub SaveAsBmp()
    ' Get the active view.
    Dim oView As View
    Set oView = ThisApplication.ActiveView
    
 'Create a new NameValueMap Object
    Dim oOptions As NameValueMap
    Set oOptions = ThisApplication.TransientObjects.CreateNameValueMap '.TransientObjects.CreateNameValueMap
    
    oOptions.Value("TransparentBackground") = True 'True
    oOptions.Value("OnlyShowActiveComponentsForIn-PlaceEditing") = True
    oOptions.Value("OnlyShowActiveComponentsForInPlaceEditing") = True
    oView.Fit
    Call oView.SaveAsBitmapWithOptions("C:\Temp\TestB2.bmp", 0, 0, oOptions)
End Sub

As I am looping through the 'parts only' bom rows I won't be using ThisApplication.ActiveView.

Do you know how I could access an image from each BOMRow item?

If you just want to save the thumbnail(IPictureDisp) of a document via API you can refer to below posts:

Hope they help.

@YuhanZhang  Yes that is what I'm trying to achieve. I'm struggling to add the correct references for any of the codes in the links you sent me to work in iLogic environment.

It fails on either SavePicture or Compatibility.VB6.IPictureDispToImage because of missing reference to my project.

 Could you advise on what I would need to add to get either of these methods to work?

AddReference "blah blah"

or

Imports blah blah

[YuhanZhang]

To add the reference to Compatibility.VB6 you need to add it as below in your .Net project(create a VB.net project to try it):

Or use Browser... to reference it from GAC using below path:

C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.VisualBasic.Compatibility\v4.0_10.0.0.0__b03f5f7f11d50a3a\Microsoft.VisualBasic.Compatibility.dll

And in iLogic Rule editor I think you can just add below line to the Header Statements area:

Imports Microsoft.VisualBasic.Compatibility.VB6 

Please let me if any more problems.

@YuhanZhang thank you for your help. I'm still getting an error unfortunately.

My full code is:

AddReference "stdole.dll"
AddReference "Microsoft.VisualBasic.Compatibility.dll"
Imports Microsoft.VisualBasic.Compatibility.VB6

Sub Main SaveThumbnail()
' Get the active document.
Dim doc As Document
doc = ThisApplication.ActiveDocument

' Get the thumbnail from the document.
Dim thumb As Inventor.IPictureDisp
thumb = doc.Thumbnail

' Create the filename for the bmp file so it is the same
' as the document name but with a "bmp" extension.
Dim filename As String
filename = Left$(doc.FullFileName, Len(doc.FullFileName) - 3) & "bmp"

' Save the thumbnail.
'Call stdole.SavePicture(thumb, filename)
img = Compatibility.VB6.IPictureDispToImage(thumbnail)

End Sub

This is the error I get is with Compatibility.VB6.IPictureDispToImage:

Reference required to assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' 

Otherwise if I try using SavePicture method I get this errror:

'SavePicture' is not declared. It may be inaccessible due to its protection level.

Do you know how I can fix to get either of these to work?

[YuhanZhang · Accepted solution]

Here is the updated iLogic code, please check if it works there:

AddReference "system.drawing.dll"
AddReference "stdole.dll"
AddReference "Microsoft.VisualBasic.Compatibility.dll"
Imports Microsoft.VisualBasic.Compatibility.VB6

Sub Main()
' Get the active document.
Dim doc As Document
doc = ThisApplication.ActiveDocument

' Get the thumbnail from the document.
Dim thumb As Inventor.IPictureDisp
thumb = doc.Thumbnail

' Create the filename for the bmp file so it is the same
' as the document name but with a "bmp" extension.
Dim filename As String
filename = Left$(doc.FullFileName, Len(doc.FullFileName) - 3) & "bmp"

 
Dim img As Drawing.Image
img = Compatibility.VB6.IPictureDispToImage(thumb)

Call img.Save ("C:\temp\custom.bmp")

End Sub
