how to getStringAsPoints(); True Type Font ??

Hi, i’m trying to get points of a string with getStringAsPoints();

like getCharacterAsPoints(); in fontShapesExample

but i can’t find a way to do this

i’m doing something like this but i’m getting a bunch of errors

  
  
	String letter;  
	  
	letter =  "hey";  
	  
	testFont.loadFont("Batang.ttf", 60, true, true, true);  
	  
	testFont.getStringAsPoints(letter);  
	  
	ofBeginShape();  
	for(int k = 0; k <(int)testFont.getOutline().size(); k++){  
		if( k!= 0)ofNextContour(true) ;  
		for(int i = 0; i < (int)testFont.getOutline()[k].size(); i++){  
			ofVertex(testFont.getOutline()[k].getVertices()[i].x, testFont.getOutline()[k].getVertices()[i].y);  
		}  
	}  
	ofEndShape( true );

a couple notes:

when you’re writing code, compile regularly to check for errors. the first bug is that you wrote “String” instead of “string”.
getStringAsPoints() returns a vector, but you’re not doing anything with that. you can remove that line of code.

can you try fixing that, and then posting more details about what errors you’re getting exactly?

I try to do the same thing and it works:

  
  
void testApp::draw(){      
    string letter = "hey";  
    ofTrueTypeFont testFont;  
      
    testFont.loadFont("verdana.ttf", 60, true, true, true);  
      
    ofPoint startPos;  
    startPos.x =  0;  
    startPos.y =  ofGetWindowHeight() * .5;  
      
    vector<ofTTFCharacter> characters = testFont.getStringAsPoints(letter);  
          
    for(int k = 0; k < characters.size(); k++)  
    {  
        for(int j = 0; j < characters[k].getOutline().size(); j++)  
        {  
            if(j>0)   
                ofSetColor(255, 0, 0);  
            else   
                ofSetColor(255, 255, 255);  
            ofBeginShape();  
            for(int i = 0; i < characters[k].getOutline()[j].size(); i++)  
            {  
                ofVertex(startPos.x + characters[k].getOutline()[j][i].x, startPos.y + characters[k].getOutline()[j][i].y);  
            }  
            ofEndShape();   
        }  
    }     
}

but i don’t know how i can detect if one path is inside one other. Maybe i only need to check if one point is inside other path.
