Accessing Frames in MultiFrame TIFF RRS feed

  • Question

  • User1122355199 posted
    Hello everyone and thanks for your help in advance. I am developing an application that needs to access multi-frame (page) tiff (i.e. a fax). I have figured out how to open the first frame, but can't seem to figure out how to iterate through the various frames in the image. Could some please give me an example or point to soewhere I can get started? Any help is greatly appreciated. Thanks.

    Hi, I think this is what your looking for??? I recently developed an application which basically 1. takes a multipage tiff image, 2. splits it up into a frame array 3. saves each frame to disk as a single tiff image 4. allows you to navigate through the frames 5. select a frame or multiple frames 6. if more than one frame was selected it creates a new multiframe tif image 7. indexes the selected tif image or newly created multiframe tiff image against customer applications in a database. This was all developed with help from BOB POWELLS website. have a look here http://www.bobpowell.net/gdiplus_faq.htm I wrote this code this morning (on my companies time :o) ) simply create a windows forms project and put this into it.

    hope i was of help? any questions, fire away!
