2007.08.08 12:25 "is cpContigBufToSeparateBuf() function (of tiffcp.c) working for bytes_per_sample less than 1", by Anurag Singh

Hello All

I got a image on which currently i am working.  I am using libtiff 3.8.2.

Details of  image

imagewidth = 16
imagelength = 16
bitspersampel = 2
sampelPerPixel = 2
planerconfig = PLANARCONFIG_SEPARATE
image type = strip

I was making copy of  the image, but at the time of writing image
data cpContigBufToSeparateBuf() function (tiffcp.c) corrupt the heap.
This function take bytes_per_sample and we have hardcoded as 1 in
writeBufferToSeparateStrips() function.

That means we are not able to handle the image which have
bytes_per_sampel less than 1. Please suggest me what i have to do?

Thanks in Advance
Regards
Anurag Singh
