Naive gradient creation with OpenFrameworks

NaiveGradient.cpp

  //set the image size
	int imageWidth = 960;
	int imageHeight = 540; // change these to any integers

  //instanciate a gradient variable
    ofImage gradient = ofImage();
	gradient.allocate(960,540,OF_IMAGE_COLOR);


	ofColor leftColor = ofColor::black; //these are your gradient colors
	ofColor rightColor = ofColor::white;
	

	ofColor currColor = ofColor::black; //current color for a giver row in the image


	//set the image pixels - looping through them sounds like a good idea, eh? 
	for(int pixelsRow = 0; pixelsRow < imageWidth; pixelsRow++)
	{

		float value = ofNormalize(pixelsRow, 0, imageWidth);
		currColor = leftColor.getLerped(rightColor, value);

		for(int pixelsHeight = 0; pixelsHeight < imageHeight; pixelsHeight++)
		{
			gradient.setColor(pixelsRow, pixelsHeight, currColor);
		}
	}

	//here, we shall update the texture on the GPU
	gradient.update();
