Grayscaling

Hi,

I have a scanning application, which scans to tiff files. Generally, we're scanning letters and text documents, sometimes passports and driving licences etc. I am then exporting to another application the tiff files, but in pdf format. The files need to be viewed in a browser and it is obviously easier to view them as pdfs.

The images are being converted with QuickPDF. I load the tiff file to a stream and then convert with the following routine (various irrelevant lines omitted):

QP.AddImageFromStream(stream, 0); 
QP.DrawImage(1, 1, Width, height);

This all works well. However the images are generally scanned in as 1 bit.

If viewing as tiff then most tiff viewers refilter an image (ie grayscale) so you can actually read what is on the page. However, acrobat doesn't seem to do this, so a lot of documents (in particular passprots and driving licences) are effectively illegible when viewed in pdf.

Is there anything that can be done when with QuickPDF when creating the pdf in the first place to improve the legibility of the pdf or (and apologies as I know this is not the purpose of this newsgroup) does anyone know of anything that can be done with Acrobat settings to achieve the same result. I've looked at Acrobat options and could find nothing.

Many thanks

Mark

I'll give it a try.

Thanks.
