This should read the tag for you.

    LEAD1.ReadTag "C:\file.tif", 1, 262

If it returns SUCCESS then you can check what LEAD1.Tag says.

Yes SUCCESS = 0.  LEAD1.Tag is a string variable, so you just read it like any other string variable.  Do you have the help file?  You can send an email to support@leadtools.com and request for the v11 help file.

Thanks for your help Jigar 

Unfortunately I havent been able to accomplish my task just yet. This is the segement of the code im using. I read the tag successfully but i can actually read what the photometric interpretation is. All I get is an empty string

If .LEAD1.ReadTag(FImage, 1, 262) = 0 Then
    MsgBox "The Photometric Interpretation is :  " & .LEAD1.tag 
End If

Im not sure what im doing wrong but I`ll definitely ask for the v11 help and read it to see if i can finally fix my problem

Hello again

I`ve been browsing through the help files and the examples that ship with LeadTools v11.5 but I have not found an example that uses the readtag, gettagdata or gettagcount methods . As i said in my previous post if I try to read LEAD1.tag all I get is an empty string.

So how exactly to I read a tag ?

Thanks for your help

Here's an example I tried with v11.5 to read a tag:








LEAD1.ReadTag "ocr1.tif", 1, &H131 'read the Software tag
Dim tagData
tagData = LEAD1.GetTagData(0) 'the newly read tag
MsgBox tagData
