imgcodecs: Add rgb flag for imread and imdecode #25809 Try to `imread` images by RGB to save R-B swapping costs. ## How to use it? ``` img_rgb = cv2.imread("PATH", IMREAD_COLOR_RGB) # OpenCV decode the image by RGB format. ``` ## TODO - [x] Fix the broken code - [x] Add imread rgb test - [x] Speed test of rgb mode. ## Performance test | file name | IMREAD_COLOR | IMREAD_COLOR_RGB | | --------- | ------ | --------- | | jpg01 | 284 ms | 277 ms | | jpg02 | 376 ms | 366 ms | | png01 | 62 ms | 60 ms | | Png02 | 97 ms | 94 ms | Test with [image_test.zip](https://github.com/user-attachments/files/15982949/image_test.zip) ```.cpp string img_path = "/Users/mzh/work/data/image_test/png02.png"; int loop = 20; TickMeter t; double t0 = 10000; for (int i = 0; i < loop; i++) { t.reset(); t.start(); img_bgr = imread(img_path, IMREAD_COLOR); t.stop(); if (t.getTimeMilli() < t0) t0 = t.getTimeMilli(); } std::cout<<"bgr time = "<<t0<<std::endl; t0 = 10000; for (int i = 0; i < loop; i++) { t.reset(); t.start(); img_rgb = imread(img_path, IMREAD_COLOR_RGB); t.stop(); if (t.getTimeMilli() < t0) t0 = t.getTimeMilli(); } std::cout<<"rgb time = "<<t0<<std::endl; ``` ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [ ] There is a reference to the original bug report and related work - [ ] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [ ] The feature is well documented and sample code can be built with the project CMake
