the problem I wanted a small scan function to -> pdf to insert to an application i prefer to not sent to final user many Dll i saw on Rpreview Antonio made a pdf for all pages of rpreviews into a pdf..it not use extern dlls
The scan software (dll) does that. I don't thing you need other dll's but if you want to convert an existing image to pdf then you can choose to use the scan software (dll) or converter like nconvert. If you are going to do scanning I don't think you can get away without some kind of dll, ocx, or exe to run the scanner.
