StefanBruens	8d78400052	Merge pull request #16494 from StefanBruens:jpeg2000_openjpeg_port Jpeg2000 OpenJPEG port * OpenJPEG based JPEG2000 decoder implementation Currently, the following input color spaces and depth conversions are supported: - 8 bit -> 8 bit - 16 bit -> 16 bit (IMREAD_UNCHANGED, IMREAD_ANYDEPTH) - RGB(a) -> BGR - RGBA -> BGRA (IMREAD_UNCHANGED) - Y(a) -> Y(a) (IMREAD_ANYCOLOR, IMREAD_GRAY, IMREAD_UNCHANGED)) - YCC -> Y (IMREAD_GRAY) * Check for OpenJPEG availability This enables OpenJPEG based JPEG2000 imread support by default, which can be disabled by -DWITH_OPENJPEG=OFF. In case OpenJPEG is enabled and found, any checks for Jasper are skipped. * Implement precision downscaling for precision > 8 without IMREAD_UNCHANGED With IMREAD_UNCHANGED, values are kept from the input image, without it components are downscaled to CV_8U range. * Enable Jpeg2K tests when OpenJPEG is available * Add support for some more color conversions Support IMREAD_GRAY when input color space is RGB or unspecified. Support YUV input color space for BGR output. * fix: problems with unmanaged memory * fix: CMake warning - HAVE_OPENJPEG is undefined Removed trailing whitespaces * fix: CMake find_package OpenJPEG add minimal version * Basic JPEG2K encoder Images with depth CV_8U and CV_16U are supported, with 1 to 4 channels. * feature: Improved code for OpenJPEG2000 encoder/decoder - Removed code duplication - Added error handlers - Extracted functions * feature: Update conversion openjpeg array from/to Mat * feature: Extend ChannelsIterator to fulfill RandomAccessIterator named requirements - Removed channels split in copyFromMatImpl. With ChannelsIterator no allocations are performed. - Split whole loop into 2 parts in copyToMat -> where std::copy and std::transforms are called. * fix: Applied review comments. - Changed `nullptr` in CV_LOG* functions to `NULL` - Added `falls through` comment in decoder color space `switch` - Added warning about unsupported parameters for the encoder * feature: Added decode from in-memory buffers.

pasbi	9f5f64e14e	Merge pull request #12192 from pasbi:pfm * created new decoder and encoder for PFM pfm file format stores binary RGB or grayscale float images. * added test for pfm codec * replaced large with short licence header * little/big-endian-check is now compile time * fixed width/height confusion, improved big/little endian recognition, fixed scaling issue and Improved signature check * adapted tests to handle float images well * removed data-dependency: lena.pfm the lena image is now loaded is pam and converted to pfm. * fixed bug in endianess detection macro * Added endianess detection for android and win * removed fancy endianess detection endianess detection will be implemented in cmake scripts soonish. * fixed minor warnings * fixed stupid elif defined bug * silenced some implicit cast warnings * replaced std::to_string with std::stringstream solution std::to_string variant did not build on android. * replaced new endianess macros with existing ones * improved readability	6 years ago

Roman Donchenko	9c01a96b14	Set minimal zlib version to 1.2.3. Rationale: 1.2.3 was a security update, and we should avoid using versions with known security vulnerabilities.	11 years ago
Roman Donchenko	6fed0e85c2	Cut down on the use of ZLIB_LIBRARY/ZLIB_INCLUDE_DIR. They're not listed in the documentation for the FindZLIB module, so we shouldn't use them unless necessary.	11 years ago

Roman Donchenko	e2ef2a5781	Refactored image format library finding logic. Now the HAVE_* macros are set in cvconfig.h. Most of them already were there, but were nonfunctional.	12 years ago
Roman Donchenko	ca8b621b4f	Refactored detecting several Apple-related technologies. Now the HAVE_* macros are set using cvconfig.h. Previously most of them already were there, but were always undefined. One, HAVE_COCOA, I had to add. This also makes the CMake code more consistent; now, WITH_* variables are always checked in cmake/, while HAVE_ variables are checked in modules/highgui/CMakeLists.txt.	12 years ago
