The implementation is an adaptor class, which takes any C++ +stream from the user and in return it deposits i/o operation method pointers +(e.g. read, write, seek and close) into the tiff's library client state. + +The class TiffStream has an overloaded factory method - makeFileStream - +which takes the C++ stream as an argument, calls TIFFClientOpen and returns +a tiff handle. The class retains the tiff handle in its local state and +provides a helper function (getTiffHandle) to query the handle at any time. +Additional helper method - getStreamSize - provides the stream size to the +user. The implementation assumes client responsibility to delete the stream +object. The class calls TIFFClose at destruction time. + +Attached are a definition (tiffstream.h) and an implementation +(tiffstream.cpp) files of the TiffStream class. No changes are required to +the tiff core piece and the class sits on top of the library. The code is +fairly tested at this point and is used internally in Shutterfly imaging +software. The code is portable across WindowsNT/Linux/Solaris. + +We at Shutterfly believe this software has benefits to the larger community +of tiff library users and would like to contribute this software to be part +of the tiff distributed package. Let me know of any issue. + +Thanks +Avi |
