how to use the TIFF IFILTER programatically.
I just want to call it from the command line like this and get the OCR'd text back.
myprog filename.tiff
The windows 7 SDK has FILTDUMP which isn't source supplied, and anyway, when I use that I get

View 5 RepliesI'm trying to convert a .bmp into a TIFF. Here's my attempt:
Bitmap bmp = new Bitmap("C:Documents and SettingsAdministratorDesktopDoc Folder\_f.bmp")
bmp.Save("C:Documents and SettingsAdministratorDesktopDoc Folder\_f.tif", ImageFormat.Tiff)
It doesn't work. Debug feedback:
Name 'bmp' is not declared. (BC30451)
Method arguments must be enclosed in parentheses. (BC30800)
'Bitmap' is a type and cannot be used as an expression. (BC30108)

convert pdf to multipage tiff?
View 2 RepliesI am writting a VB.Net application. I need to be able to convert either a Word or PDF file to TIF format.
View 4 RepliesI can use to convert several thousand PDFs to TIFFs. Free would be great but willing to pay if the cost is within reason.One requirement that many of the tools I have researched seem to miss is that I need to be able to do this in memory.I am working with PDFs that are stored as binary in a SQL database so through SSIS, I would like to pull that binary, convert to TIFF, then send it off to a webservice I will be working with via stream. Unfortunately, it seems that most utilities I have looked into expect the pdf to be on the file system and I would definitely like to avoid writing a temp file to disk to do this conversion. For me that ruled out GhostScript and pretty much anything that's based on it.Also, the PDFs I am working with are rather old (v1.3) so the assembly should be rather forgiving/flexible (PDFFocus errors out on all my PDFs but works fine with newer ones).Based on posts from StackOverflow, it seems like Atalasoft or PDF4NET might work but both are a little too pricey for me so I am looking for some additional suggestions. Given that this process will be embedded in a script task in SSIS 2008, this will have to be .NET.
View 6 RepliesI have created a simple database programme in VB2010 Express. There is one table called stock_main_table and one 'child' table called Stock_issue_table. The main part essentailly holds the part number and the issue makes a record of each time that part is used. Its a one to many type arrangement.In the main table I have a PRI key called ID_Number and in the child I have a field called 'control'. The control has a relationship with the PRI key in the main table. So each time you create a new line in the child datagrid you retain the same number for that record. All standard simple stuff.
When I run the programme the main table comes up OK and the datagrid for the child comes up OK. If I add a record, I can add plenty of children to it no problem. The records all save OK. You can amend a record as well without an issue. The trouble comes as soon as you DELETE a record and then hit save. The DELETE seems to work and the records (parent and child) all disappear, but as soon as you try to save you get a The DELETE statement conflicted with the REFERENCE constraint error. I have tried and tried to fix this but can't.This is the full text of the exception, if anyone needs anything else then please just ask and I will post it. There is no code with this other than what is created when the dataset is dragged onto the form

I've tried all sort of Image and Graphic calls and just can't save the meta file as a .tiff. I even tried to create a new bitmap and draw the metafile onto it. I always end up with a GDI exception being thrown.
I have an ASP.NET application (vb.net codebehind) that has serious performance problems because of its storage of TIFF files in one server share. There are over a million .TIF files there now! The application tracks the scanned images of property with a corresponding row in an Oracle database table. We have this idea that it might be better to store the images themselves in a new Oracle table.
The alternative solution we are thinking of is to split up the server share into multiple folders by State (an OH folder, a WV folder, a VA folder, etc.) Seems like the database option might make more sense long-term, but how do we do it? Can a TIFF be stored in a BLOB column and then extracted back into TIFF format using .NET?
I've been working on a project that converts several file formats to a PDF in VB.NET/C#. The specific files are DOC, TXT, JPG, TIFF, HTML.
Actually I already have a solution for DOC/TXT to PDF using Bullzip PDF Printer by sending the files to the PDF Printer using VB.NET. However, each time it converts a file, MS Word opens and then closes once the file is sent to the printer. It really slows down the process.
As for TIFF to PDF, I haven't found a solution for it at this time.
I require SDKs or Commandline tools and not PDF convertion applications, since I need to integrate this function in my program. I prefer free or open source SDKs but commercial ones are accepted as well.
