@deokgyuhan Thank you for the effort Can you please add the functionality to blending two images and also develop another method which add option to add gradient and colour to background of given image E.g the following is C++ example code
std::string composeImages(const std::string& base64Image1, const std::string& base64Image2) { // Decode Base64 strings to Mat objects efficiently cv::Mat mat1 = base64_decode_to_mat(base64Image1); cv::Mat mat2 = base64_decode_to_mat(base64Image2);
// Create a new Mat with appropriate dimensions cv::Mat combinedMat(cv::Size(std::max(mat1.cols, mat2.cols), mat1.rows + mat2.rows), CV_8UC3);
// Copy the image data efficiently mat1.copyTo(combinedMat(cv::Rect(0, 0, mat1.cols, mat1.rows))); mat2.copyTo(combinedMat(cv::Rect(0, mat1.rows, mat2.cols, mat2.rows)));
// Encode the combined Mat back to Base64 return mat_to_base64(combinedMat); }
// Helper functions for Base64 encoding/decoding using a third-party library cv::Mat base64_decode_to_mat(const std::string& base64Image) { std::vector decodedData = base64_decode(base64Image); cv::Mat mat = cv::imdecode(decodedData, cv::IMREAD_COLOR); return mat; }
std::string mat_to_base64(const cv::Mat& mat) { std::vector encodedData; cv::imencode(".png", mat, encodedData); return base64_encode(encodedData); }
