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)

Please continue working in this PR: #16494 |
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.
…ANGED With IMREAD_UNCHANGED, values are kept from the input image, without it components are downscaled to CV_8U range.
Support IMREAD_GRAY when input color space is RGB or unspecified. Support YUV input color space for BGR output.
