sigh I'm sorry to say that I'm using Intel IPL (Image Processing Library) in some image processing code I'm working on. This is the tale of my struggle with getting my images to rotate correctly. I have a source image. It has a size (w, h) which is not necessarily square. It is going to be rotated by angle theta. I've calculated the ou...
Hello, I need to convert raw image data to jpeg. But I don't need anything special in terms of best quality, or minumum size etc. Only thing I need is minumum CPU usage. I am new to jpeg compression. Can you please advice about which parameters will have the lowest CPU usage while converting jpeg? I would like to use IPP(intel perform...
I have a postscript file and want it to be printed on a IPP capable device (or CUPS server). What is the minimal code and dependencies I could get away with to do that. Using LPR or libcups gives me lot of cross-plattform dependencies. So my first approach was to implement a minimal subset of IPP (the protocol used by cups and many mode...
We're trying to compare two equally sized native arrays of signed int values using inequality operations, <, <=, > and >=, in a high performance way. As many values are compared, the true/false results would be sotred in a char array of the same size of the input, where 0x00 means false and 0xff means true. To accomplish this, we're usi...
Is there any way in Java to print to a specific IPP printer? All of the sample code and tutorials I've found focus on how to print a particular type of document, using something like the following: DocFlavor flavor = DocFlavor.INPUT_STREAM.POSTSCRIPT; PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(MediaSize...
I have an audio file and I am iterating through the file and taking 512 samples at each step and then passing them through an FFT. I have the data out as a block 514 floats long (Using IPP's ippsFFTFwd_RToCCS_32f_I) with real and imaginary components interleaved. My problem is what do I do with these complex numbers once i have them? ...
Hello Everyone! I have a project that uses Boost.Asio and the Media-Decoding-Samples that come with the Intel IPP-Library. The problem is the following. If I compile the project without defining WIN32_LEAN_AND_MEAN, Asio complains with the infamous "winsock.h already included" error. If I define the macro, a header in the other library ...
I've built a program that uses mkl and ipp that runs on mac and linux. I'm now building that program for Windows using cygwin and gcc, and can't get it to link. The errors I'm getting are: Warning: .drectve -defaultlib:"uuid.lib" ' unrecognized ../../../bin/libMath.a(VectorUtility.cxx.o):VectorUtility.cxx:(.text+0x95): undefi...
I have source code that was not written by me, and I cannot contact the author. It is written in C++ and requires libjpeg, boost, and the Intel Performance Primitives. Compilation was a chore, but after days of problem solving, it compiles. Now, I get the following runtime error: error while loading shared libraries: libippi.so.5.1: can...
Hi i use DEV C++ compiler in windows xp sp2 and recently i downloaded the IPP libraries. I installed successfully , i set up the compiler directories from option menu to IPP directories but when i try to compile an ITT program i get linker error for the ITT functions. Is there a solution? ...
I'm writing a print system that puts a simplified interface on top of CUPS. Users drop jobs into one queue, the system processes them in various ways (statistics, page quotas, etc.), and then offers the user a web interface to dispatch the job to one of multiple printers. Since there may be several user kiosks, an admin station, etc.,...
I am building a C++ application that uses Intel's IPP library. This library is installed by default in /opt and requires you to set LD_LIBRARY_PATH both for compiling and for running your software (if you choose the shared library linking, which I did). I already modified my configure.ac/Makefile.am so that I do not need to set that vari...
IPP is a C library, with hundreds of functions like this: IppStatus ippiTranspose_8u_C1R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize)); To be able to call these functions in a more convenient, safe and consistent way, we need a C++ wrapper fun...
I would like to create linear gradient using IPP (Integrated Performance Primitives) functions and avoid pixel-by-pixel color manipulation. In other words, I can't find appropriate function or combination of functions that will alow me to create RGB image with gradient R0 to R1, G0 to G1, B0 to B1 (initial and final RGB values). I can c...
In order to check for newer version, one has to know the current version the program is running with and the latest version available for download. The current version can be seen from the install path, for example: /opt/intel/ipp/6.1.5.061/ The latest version can be seen by checking the available samples, for example: http://registrat...
Is there any tool existing or any shortcut that can be used to extract print job payload from IPP packets(captured via wireshark utility)? Write now I'm manually inspecting/dissecting the packets byte per byte which is kind of excruciating especially with requests which spans several packet exchanges (HTTP Continue). Thanks ...
I was wondering, is there a some kind of infographic or tutorial out there that describes the various branching of programming education? Let me provide an example: I'd like to create a camera tracking program using, say, Intel IPP and Xcode. This is a pretty advanced project for a beginner, so I'd like to know what I have to know how t...
