How to do Color enhancement: brightness, contrast, gamma, hue, saturation through VC++ program. Can any one help me.
We’ve been working on creating some sample applications using Intel® Cilk Plus technology. So far we have published 10 samples. You can find them at Intel® C++ Compiler Code Sample.
All the samples are published under the same book. You can easily navigate the samples from the left panel. Each sample page contains the abstract and code snippets to show you how we applied the Intel Cilk Plus. It also includes the associated performance data collected.
I tried compiling the following code with non-commercial icpc compiler:
I compile a C file (whose function calls a static fortran library) with icl ( Version 220.127.116.11) on windows 7 64 bits. i compile with the command prompt s provided by intel, the one for 32 bits target and the one for 64 bits target.
First of all, sorry for this report, it looks like a nasty bug and I can't give you a simple reproducer (closed source and stripped-down example just works fine).
I'm performing the following calls on a highly templated with many inheritance code:
size += static_cast<std::vector<pairN>>(_ref.A::_map)[j].second.size(); size += _ref.A::_map[j].second.size();
The first line compiles fine, the second does not, with the following error message:
Problem: I am trying to install on a LinuxMint 15 (Olivia) 64-bit System (Ubuntu derivate) that does not support ia32-libs any more. Naturally, this results in Intel C only working for 64-Bit compilation, since libc6:i386 can't be found. The installation of intel C works fine for 64-bit, but fails compiling for 32-bit: Some headers can't be found by icc.
Alltough ia32-libs is still installable (...which I did already!), my system does not recognize the 32-bit libs from ia32-libs (other apps using 32-bit, e.g wine, are working!)
Code using _mm256_unpacklo_pd/_mm256_unpackhi_pd in cunjunction with _mm256_permute2f128_pd produce wrong code. Moreover, the exact same code pattern being used elsewhere with a different constant mask for permute is working correctly. The workaroudn usign volatile is of course underperforming.
Same code works and codegen correctly on gcc and clang.
I have a precision issue with the below code. If I do the calculations for the same input in my calculator I get -13421772.8
Whereas with compiler I get -13421773.0, and this is a considerable difference for us.
The variable used for the above observation is ‘tmp’.
Please help us in resolving this.
I am getting these strange errors:
