Hello All,
This is the problem I' trying to solve:
to read a strip but not a whole strip but only part of it...reason: some of the strips we deal with are huge(long) and hence by having the ability to break them down and process them allows me to parallel process. I hope to break them down to a mxn (no. rows x length) and store them as my data structure (called tiles - different from the tiff tiles).
What I have tried:
I have tried hacking the TIFFReadRGBAStrip() ..which involved changing the gtStripContig()
so I have a gtStripContigWithOffsets(TIFFRGBAImage* img, uint32* raster, uint32 w, uint32 h, uint32 wOffset /*= 0*/, uint32 hOffset /*= 0*/) but before I paste code and ask for scrutiny....
was wondering if someone else out there has tried it?
Also, if someone has successfully streamed a tiff file and could point me in the right direction that would be helpful.
I am using c#. and the libtiff has a managed wrapper.
Cheers,
Nikhil
