Merge TIFF Files

Hello Experts!!!
I need some help with this one!
I'm creating TIFF images on the fly, but I need to stack them in a file with offsets in an XML File.

For example 3 tiff images in one file
The first one starts at offset 0 and for size of 3211
The Second one starts at 3211 and for size of 1547
The Thrid one starts at 4758 and for size of 1465

I hope you get the idea...I need to stack them up so another application can read the offet and size to pull the image out from the one file.

How can I accomplish this?

Here is my code that generates the images, but as I create them how can I merge them into one file?

'Image Information:
        Dim ImgOffset As Int32 = 0
        Dim ImgLength As Int32 = 0
        Dim ImgResolution As Int32 = 200
        Dim ImgHeight As Int32 = 574
        Dim ImgWidth As Int32 = 1312

        Dim ImageWriter As IO.FileStream = New IO.FileStream("C:\TestImage.tif", FileMode.Create)
        Dim memstrm As IO.MemoryStream = New IO.MemoryStream
        Dim ticket As New Bitmap(ImgWidth, ImgHeight)

        'Fonts:
        Dim TicketID_Font As New Font("Arial", 20, FontStyle.Regular)

        Dim ticketGraphics As Graphics = Graphics.FromImage(ticket)
        ticketGraphics.FillRectangle(Brushes.White, 0, 0, ImgWidth, ImgHeight)
        ticket.SetResolution(ImgResolution, ImgResolution)

        ticketGraphics.DrawString("-- My Ticket --", TicketID_Font, Brushes.Black, 520, 90)
        ticketGraphics.DrawString("Ticket ID: 800001", TicketID_Font, Brushes.Black, 10, 160)
        ticketGraphics.DrawString("Ticket Amount: 111", TicketID_Font, Brushes.Black, 10, 200)
        ticketGraphics.DrawString("Date: " & Now().ToShortDateString, BatchID_Font, Brushes.Black, 10, 240)

        ticket.Save(memstrm, System.Drawing.Imaging.ImageFormat.Tiff)
        memstrm.WriteTo(ImageWriter)
        ImgLength = memstrm.Length

        ticket.Dispose()
        memstrm.Close()
        memstrm.Dispose() 

Open in new window


In the above example I can get the Image Length to put into my XML file, where I'm getting stuck is how can I add my next image to my File Stream (ImageWriter)?

I've done append on the File Stream...but the receiving application doesn't like that so it may need to be something like multi-page to merge them together.

Can someone provide me with an example of taking my code and creating a merged file?

Thanks,
Mark

Hi Mark,
I'm glad to see that you found the question I referred you to that kaufmed answered brilliantly, and then you posted this new question, but does this mean that you're abandoning the previous question, which you haven't closed yet? Regards, Joe

To be clear:  Do you want a multi-page TIFF, or a single file that has multiple TIFFs embedded within it (not exactly a single-page TIFF).

Kaufmed,

I was able to figure it out based on the code you had in the previous post.
That was wonderful and it really helped me figure out what I needed to do to get through my issue.

I needed a single file that has muliple TIFF's embedded within it...NOT a Multi-Page.

I appreciate you putting that code together for that other post and THANKS JOE for finding that solution for me.

Althought I didn't take a look at your links CodeCrusier if I ever need a Multi-Page Tiff I will review them and thanks for weighing in on my post!

Thanks everyone!!!

Mark,
You're welcome...happy to help, albeit in a minor way on this one. I'm glad to hear that you figured it out based on kaufmed's code, and I hope you'll post the solution here so other members looking for something similar can find it...much as you did with kaufmed's code. That's what the EE community is all about...helping each other. Thanks, Joe
