Text

cvui::text() renders a string. The signature of the function is:

void text (
    cv::Mat& theWhere,
    int theX,
    int theY,
    const cv::String& theText,
    double theFontScale = 0.4,
    unsigned int theColor = 0xCECECE
)

where theWhere is the image/frame where the image will be rendered, theX is the position X, theY is the position Y, theText is the text content, theFontScale is the size of the text, and theColor is color of the text in the format 0xRRGGBB, e.g. 0xff0000 for red.

Below is an example of the text component. The result on the screen is shown in Figure 1.

cvui::text(frame, 90, 50, "Hello world");
