Display Qbytearray as Image in QT 5.12.9 version
-
I am reading the QByteArray using QTcpSocket and converting the array into the cvMat image. to display the image using imshow().but i am getting gray image. code is as follows.
cv::Mat img,img1;
img.cols=320;
img.rows=240;
img = cv::Mat(240,320, CV_8UC1,array.data());
cv::cvtColor(img, img, CV_GRAY2RGB); //
cv::imshow("image display",img);
cv::waitKey(5000);after cvtColour() function also its not converting into colour image.
Thanks in advance.

Start by determining whether it's your code not doing what you want with correct data, or whether you're not transferring/receiving the right stuff over socket. The two issues are quite independent of each other, you need to know which of the two is problematic. -

Well, should it be the expected behavior? I mean, since you're doing:
cv::cvtColor(img, img, CV_GRAY2RGB)and CV_GRAY2RGB will convert grayscale to RGB color space but it won't color your already gray image...
See this answer in SO. -

I am trying to convert the cv mat image to Qimage but facing error: ‘class Ui::MainWindow’ has no member named ‘display_image’

Should that issue be a new post on its own?
