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.	8 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.	8 years ago

guoxuedong	e69253a4fb	Update exif.cpp ExifReader::getExif may enter infinite loop with jpeg image which have no EOI. For example, bytesToSkip may be set to 0 and fseek seems like fseek(f, -2 , SEEK_CUR) for image that end with RST7(FF D7) instead of EOI.	8 years ago

Dimitrios Katsaros	4e513a3346	Imgcodecs: Fixed a bug with checkSignature in GdalDecoder In cases where the signaure string contains a terminating character, the std::string member function size returns a smaller value than the allocated string. In these cases, if you then try to use substr, you will get an out_of_range exception. This patch remedies the problem.	8 years ago
Dimitrios Katsaros	6172803012	imgcodecs: Implementation of PAM encoder/decoder This patch implements the PAM image format as defined at: http://netpbm.sourceforge.net/doc/pam.html The PAM format provides a generic means for storing 2 dimensional information. This is useful for opencv since there are cases where data gets translated into non standardized formats, which makes it difficult to store and load this information.	8 years ago

Alexander Alekhin	5383a625a7	fix Win build, change default WINNT macro to WinXP Returning to Win2k value is possible via this CMake option: cmake -DOPENCV_EXTRA_FLAGS="/D_WIN32_WINNT=0x0500" ...	8 years ago
Morrison	ca318e7099	handle images with alpha better UIImages with alpha were ending up with garbage pixels in background (random memory values). Need to initialize matrix pixels before drawing UIImage with alpha on it. Note: didn’t fix Grayscale image with alpha stripping alpha in UIImage -> Mat conversion.	9 years ago
Patrick Spettel	84e1712659	Fix temporary file removal in imdecode for tiff The TiffDecoder keeps an open file handle. As a consequence the file cannot be removed before the TiffDecoder closes the file.	9 years ago

Maksim Shabunin	f3bd508e6d	GDCM: several improvements - fixed width and height order - removed unused methods - simplified signature matching - rewrote pixel format matching in more compact form - added dimensions number check (only 2 is allowed) - added target buffer size check - added debug messages in all failing points	9 years ago
Maksim Shabunin	0fd0acf2e3	GDCM: modified compilation scheme - renamed source files - guard the contents - always include	9 years ago
