, not working at the moment...

Parameters

size	Hight and width of the image matrix

}

Member Function Documentation

messageColor()

Scalar Console::messageColor ( std::string  str )

private

returns color based on the message text

• "OK:" = green
• "ERROR:" = red
• unknow = yellow

  str	string containing the message

  Returns

  Scalar: BGR color

{
 
    if (0 == strncmp("ERROR:", str.c_str(), 6)) {
        return style.fontColorError;
    }
    else if (0 == strncmp("OK:", str.c_str(), 3)) {
        return style.fontColorOK;
    }
    else {
        return style.fontColorWarning;
    }
}

setSize()

void Console::setSize

(

cv::Size

size

)

sets the size of the Matrix

functionality is equal to Console(CV::Size size);

Parameters

size	Hight and width of the image matrix

{
    this->size = size;
    img = Mat::zeros(size, CV_8UC3);
    rectangle(img, Point(0, 0), size, backGroundColor, -1);
}

addMessage()

void Console::addMessage

(

string

message

)

adds a message to de message deque

Parameters

message

string containing the message

{
    if (messages.size() >= 10)
        messages.pop_front();
    messages.push_back(message);
}

draw()

cv::Mat Console::draw

(

)

Draws the serial communication messages to the image.

Loops over al messages and draws them with a height offset of 5 pixels between each message.

Returns

the image matrix

{
    if (messages.size() > 0) {
        //Draw background rectangle
        rectangle(img, Point(0, 0), size, backGroundColor, -1);
        
        //Get text Size
        int baseLine = 0;
        Size textSize = getTextSize(messages[0], style.fontFace, style.fontScale, 1, &baseLine);
 
        //Draw all messages from de deque, offset between strings = 5 pixels
        float y = 2; //Initial y offset
        deque<string>::iterator it;
        for (it = messages.begin(); it != messages.end(); it++)
        {
            Scalar fontColor = messageColor(*it);
            Point textOrg(2, (y + textSize.height));
            putText(img, (*it), textOrg, style.fontFace, style.fontScale, fontColor, 1, 8);
            y += (textSize.height) + 5;
        }
    }
    return img;
}
