QuickPDF can not do it. You can make JPEGs or BMPs, and then convert it to TIF with a third party utility

Hi Srini!

You can use the render-functions (RenderDocumentToFile, RenderPageTo...) to convert pdf-documents or single pdf-pages to images. The supported image-types are BMP, JPEG, WMF, EMF, EPS, PNG and GIF. Converting tif to pdf works but rasterizing pdf into tif isn't supported 'till now.

Cheers and welcome here,
Ingo

Thank you,

Another question, When I compress a pdf file, it doesn't shrink the file size. What are steps for file compression.

Hi Srini!

If it's only a text-document and if the used font isn't embedded then a compress won't make a difference ;-)
The most image-types are already compressed, too. Only vectors, embedded bmps and tiffs and embedded fonts could be influenced by a compress.
There are the functions CompressContent (the whole document) and CompressPage (only the selected page) to compress vector-images and fonts in one run and there are the functions CompressFonts and CompressImages (for bitmaps).
Where's the difference now...?
CompressPage and CompressContent should be the LAST function before the save.
CompressImages should be used BEFORE adding bitmaps to the document. Please keep in mind again it doesn't have an affect if you use CompressImages adding a compressed jpeg to the document.
All what i've written here you can read in the documentation, too ;-)

Cheers and welcome,
Ingo
