zhijackchen	6df8ac0342	Merge pull request #10283 from zhijackchen:exr_export * Fix issue #10114 Convert table change From: CV_8U -> HALF CV_8S -> HALF CV_16U -> UINT CV_16S -> UINT CV_32S -> UINT CV_32F -> FLOAT To: CV_8U -> HALF CV_8S -> HALF CV_16U -> UINT CV_16S -> FLOAT CV_32S -> FLOAT loss precision CV_32F -> FLOAT Signed integer can't be presented well with UINT. Even adjust bias, CV16S and CV32S will be confused when load from exr file. Also fix CV_8S negative value incorrect bug * EXR import and export imread() from EXR returns CV_32F only imwrite() accepts CV_32 cv::Mat only and stores FLOAT images by default. Add imwrite() flag to store in HALF format. * fix compiling error * clean up * fix EXR import issues	7 years ago

gdkessler	2674c6b5e0	Merge pull request #10093 from gdkessler/gdal_image_read_fix_10089 Fix GDAL image decoding color problems identified by issue #10089, by: (#10093) * Fix GDAL image decoding color problems identified by issue #10089, by: Fixing CV_8UC1 symbol, which should be CV_8UC3 for RGB GDAL color table images. Fixing image.ptr<VecX>(row,col)[] to be (image.ptr<VecX>(row,col))[] to correctly access VecX array elements, as ptr<VecX>() returns a pointer to the VecX, not the first element of VecX. This fixes the color problem with color table gif images, and avoids out-of-bounds memory access. Respecting the color identification of raster bands provided by the GDAL image driver, and produce BGR or BGRA images. Note that color bands of images using the HSL, CMY, CMYK, or YCbCr color space are ignored, rather than converting them to BGR. When reading image files using the GDAL decoder, exit with an error if a color band is encountered that isn't used (eg. from CMYK or YCbCbr), rather than silently ignoring the band's data.	7 years ago

Jeremy Maitin-Shepard	350d483a70	grfmt_tiff: support in-memory TIFF encoding and decoding Previously, only file-based encoding and decoding were supported with the libtiff library, leading to the possible use of temporary files. This fixes issue #8483.	7 years ago
Jeremy Maitin-Shepard	2be955a0ef	loadsave: check for errors when using temp file Previously, the return value of fwrite and fclose were not properly checked, leading to possible silent truncation of the data if writing failed, e.g. due to lack of disk space. Fixes issue #9251.	7 years ago

Maksim Shabunin	87b569d812	Rewritten some tests in videoio and imgcodecs modules general: - all iterative tests have been replaced with parameterized tests - old-style try..catch tests have been modified to use EXPECT_/ASSERT_ gtest macros - added temporary files cleanup - modified MatComparator error message formatting imgcodecs: - test_grfmt.cpp split to test_jpg.cpp, test_png.cpp, test_tiff.cpp, etc. videoio: - added public HAVE_VIDEO_INPUT, HAVE_VIDEO_OUTPUT definitions to cvconfig.h - built-in MotionJPEG codec could not be tested on some platforms (read_write test was disabled if ffmpeg is off, encoding/decoding was handled by ffmpeg otherwise). - image-related tests moved to imgcodecs (Videoio_Image) - several property get/set tests have been combined into one - added MotionJPEG test video to opencv_extra	8 years ago
