.ppm images saved incorrectly using opencv

Question

I am capturing images from a camera and save using opencv as follows.

cv::Mat leftImage(height, width, CV_8UC3);
//capturing image here
vector<int> compression_params;
compression_params.push_back(CV_IMWRITE_PXM_BINARY);
compression_params.push_back(1);

 //writing as ppm image
 cv::imwrite("Image_1.ppm", leftImage, compression_params);

When saved as .png the image looks good. But saving as .ppm is not giving the expected result. Thanks in advance.

Solved!!!

A conversion from BRGA to BGR did the trick.

cv::Mat leftImage;
cvtColor(leftImage, leftImage, COLOR_BGRA2BGR);
