Hi Karpagarajan,

I checked the samples that you have sent yesterday. I already have this sample. This sample is used to extract the IPTC MetaData from jpg file only. I want to extract, edit and save the IPTC Metadata for JPG, and TIFF file.
I have no samples in C# to edit the IPTC MetaData. Please give some idea.

Thanks,

S.Balasubramanian.

Yes Balasubramanian,

I think we cannot edit the IPTC datas on image file. We can only extract the datas and use it for other purposes. I dont think, but it can be available on the net.

When going with the thrid party components(Extractor), I dont think it is not that much easier to do all the image operations. You can just get the File stream structure of the JPEG file (it will be available on the net for Joint Photographic Experts Group). And use that Stream object for extracting / editing the meta data information.

I will also search or do some R & D works regarding this and let u know before this evening.

thanks

Hi Balasubramanian,

I have given the sample R & D works i had done in IPTC. Just include this dll and use the namespace as in the following manner.(I just given the vb code)

Dim a As New IPTCObj
Dim b As String
Call a.GetIPTCData(Text1.Text, b)
MsgBox b

I just wrote the function for getting the IPTC data. It is possible to write the IPTC data onto the image. Hope it will be helpful for you. And if you want the save functionality also, i will give. Let me know. thanks.

thanks

LoadLibrary("NewIptc.dll") failed.The specified module could not be found.
Please help me to solve the problem..

Do you have any option in C# to include this dll to your project?

I dont know the exact procedure. this module should not be registered.

Hi Karpagarajan,

I have to Register this DLL using Regsvr32 to use it in C# Project. Please tell me whether it is a managed DLL or unmanaged DLL. Please send me the VB project that you have implemented this DLL.

Thanks..

Hi Karpagarajan,

I can read the IPTC metadata from the DLL that you have sent. But, I can't write the IPTC medata using this dll. Please help me to write the IPTC metadata.

Hi balasubramanian,

Very good contribution has been made to this thread and so ive made this thread sticky.

Good Luck and continue quality content posting in this thread regularly because our goal must be to get the 1st result in search engines when searched for extract iptc metadata or extract metadata or extract iptc metadata using c# etc.,

Thanks
