Creating PDF from Bitmap in dotNET

chrisM · Post by **chrisM** » Wed Oct 01 2003

Hi, I'm writing an app in VB.NET which receives an image (of a document page) from a scanner. I want to save this image as a PDF file.

Can anyone tell me if it is possible to do this without first saving the image to the disk. Is is currently living inside the app as a .NET 'Bitmap' object.
If this can't be done in .NET, is is possible in regular VB6?

Thanks in advance,

Chris.

Hello Chris,

I didn't really understand the situation you are in. But if you are able to print the bitmap to a printer than you can convert it to pdf using the PDF Converter.

The PDF Converter is a printer driver, by printing your documents to the PDF Printer you will get pdf files. A demo version of the PDF Converter is available at www.amyuni.com . All what you have to do is to install the printer on your system and print your bitmap to it.

We have a special interface to use the printer programatically from .Net.

Hope this helps !

Does the PDF Convertor support PDF encryption(ie I need the PDF that I create to be encrypted?) If it does then this could be the answer!

Just to clarify my situation, consider the following VB.NET code:

dim myBitmap as Bitmap
myBitmap = GetBitmapFromScanner()

So I now have a bitmap object in memory. What I now want to be able to do is somthing like:

CreatePdfFromBitmap(myBitmap)

Which will create the PDF file. ( know that I will have to write the code for this) but the condition is that at no point do I want to have to write the bitmap to a disk file.

Regards,

Chris.

I think you'll have to save your Bitmap into a temporary file first (maybe using a stream datatype) and then you could add it to your PDF by creating a Picture object into the PDF.

Should work!
