Convert Tiff data type in libTiff to nsdata ios

问题

I am using libtiff to create tif images. Can any one help how to convert TIFF back to nsdata.

Thanks

回答1:

Conveniently, CFData is toll-free bridged with NSData, so you can basically turn it directly into an NSData object without doing anything. Just replace the line

CFRelease(pixelData);

With

NSData *tiffData = CFBridgingRelease(pixelData);

And that's your tiffData as an autoreleased NSData object, ready to use as you wish.

Thanks for help by the community.

I figured out the answer. Just use the same function. that's it. It did not flash to me until now.
