Writing A Single-page Tiff File
Oct 27, 2011
We are using vb.net to write tiff images. After the image is first scanned into the system, we read it into bitmap memory, then we write it back out as a tif and pass in arguments that tell it what to put in the header. When we look at the original file, the header shows the "Subfile type" as "single page of multi-page image". But we noticed that after the file is written, the header now shows the "subfile type" as "Full-resolution image". We do not currently pass any argument in that tells it to do that.Is there a way to pass an argument into the function that writes the tiff file to tell it we want a single-page tiff and NOT a full resolution image? For some reason, our customer's tiff reader is not accurately reading some of these files and we believe it might be the cause of this.

I have a bunch of images that I want to save as 1 tiff file.
I can get it to read just fine. But It is not picking up frames. I think it has to do with the encoderParamters.[code]...

Ok what's happening is I'm pulling in a Tiff file that can have multiple pages. I selected the first frame, draw a stamp image to it and save it as a different file name.When I do this, it is only saving the first page of the tiff file. How do I get all of the pages to save?
vb
NetDMS.exportDocumentImageWithAnnotations(_workflow, disn, "C:JCEmailFld", "emailDocument" + currEmailDoc.ToString)

I have a BIN file which I need to write a single byte to at the end and maintain the previous data. Here is an example.Viewed with a hex editor the file may have F0 FD 48 D3 C0 as the data. I want to be able to add to the end of it FF so that when I view it with the hex editor it is displayed as F0 FD 48 D3 C0 FF. I know how to open files for putting data but how can I take those characters and write them to the end of a file. I tried using the put function ( Put #FileNo, , MyStr) where MyStr = the characters in the textbox but it doesn't seem to work. Here is some code.

I've got my self in to a pickle here.I'm trying to do something I used to do in basic? At-least I think you can do this in Basic, you know Qbasic,What I'm trying to do is put 4-8 strings on to one line separated by a comma.Example might be:
writer.writeline (bob1, bob2, bob3, bob4) Out put might look like Test, Test2, Test3, Test4
I'm tried looking in to formatting of writeline/write, but I didn't get any where with it.
Also if this is possible- I would like to be able to read it just like :
reader.readline (Rbob1, Rbob2, Rbob3, Rbob4) If anyone cold just point me in the right direction, I'm sure I can figure it out - If not... Well I will ask another question.

I have built a simple image viewer in .NET and have the requirement to display multi-frame TIFF images in the browser. Presently, I have a (ashx) handler setup to stream back JPEGs that are co-mingled in the same database as the multi-frame TIFF's and it's worth mentioning that this handler will also return the first frame of the TIFF file in its current state. In the VB.NET code below (part of the handler) I am able to identify if a TIFF file has multiple frames and I started attempting to stitch the frames together but have not had any success yet. Has anyone returned multi-frame TIFF's using a similar approach? Note: I used the How to open a multi-frame TIFF image as a reference when developing the code below.
context.Response.Cache.SetCacheability(HttpCacheability.NoCache)
context.Response.Cache.SetNoStore()
context.Response.Cache.SetExpires(DateTime.MinValue)

When looking at an array of bytes from a stream for a multi-page tiff document, can you determine where one page stops and another begins? I want to take a multi page document, let's say 50 pages and allow a user to pick different pages of that to make other muti-page documents.

I am making the belated transition from VB6 to VB.NET (2008). I would appreciate some guidance on writing arrays to a file. I need to save and load large arrays of 4-byte floats (24 x 90,000 values is not uncommon). I can load or save them using nested for-next loops, but that's quite slow. I'd like to find a single operation that can read or write the binary data.In VB6 I could accomplish this (writing case shown) with Put #1 , , MyArray()I can read and write single variables from binary files without problems in .net. For example, [code]I have looked and looked, and Googled endlessly, but cannot find out how to accomplish a single-line numeric, floating-point array read or write in VB.NET.

When and why would it be a good choice to keep the view of two different sets of information on the same page, and just change what's visible depending on different parameters?For example, an application I'm working on has three levels of users: Admin, Director and Project Manager. We have a Managers.aspx page which follows this flow of control:
If user is admin, load gridview list of directors with several simple CRUD-like properties. This includes a link for each director that, when clicked, will load a new gridview with several properties of all of the Project Managers belonging to the selected director.If user is director, load straight to the list of Project Managers that belong to this director, in the exact fashion as described in the second half of the "if user is admin" clause".This is all done on one Managers.aspx page. Why? What advantage does this hold? When else might this type of situation arise? Personally, this seems like a job for two separate pages. One listing the directors, and another listing the Project Managers.

I am trying to figure out a way to convert a pdf, that could have multiple pages, into a multi page tiff file. I realize there are 3rd party programs that could do this but I need to be able to do it through code. I found this code snippet but am having problems with it because I am missing namespaces, I think. I do have a reference to the Adobe Acrobat 10.0 Type Library.
HTML
Dim FileName As String
Dim image As String = "Image"
AcroXApp = CType(CreateObject("AcroExch.App"), Acrobat.CAcroApp)
'Removing toolbar buttons from the user interface
With AcroXApp
.ToolButtonIsEnabled("SaveAS")

I need to convert many separate .tiff or .mdi files scanned invoices to .pdf but, I need to retrieve the invoice number from each file and rename each file with the invoice number. I am running VS 2005, and have looked at Itextsharp,hp document imaging, simple ocr, aquaforest, adobe sdk. The problem with all, is either compatibility or cost. I would like to avoid developing an application that enters FindWindow Lib "user32" press 'OK' to use demo ocr software.

I have converted pdf file to Tiff file using 3-party software. When I open the new Tiff file using 'Windows Photo Gallery', I can view both pages of the converted file. However, when I open the the Tiff file in a picture box in my app. I can only view the first page. So, my question is how can I view multiple pages of a Tiff file in a picture box?
