Black border in exported video

Question

When I am in presentation mode I see picture in the correct ratio without border. But exported video with same configuration have black border. (Source images have small size then output video.) I need output video without border as in preview...

Answer 1

it's a simple 2D operation. first you should find out how many pixels the "troubling" black border has, and then set a clip on it. the first idea with resizing is kind of complicated one, i admit:)
1. find out the size of your image (width, height)
2. get a clipping bounds (use Graphics.getClipBounds) and store it into Rectangle
4. check if your image intersects correctly with the clip
5. if yes, draw/store it with the new size
protected void paintComponent(Graphics g) {
    // paint the logo at location logoX, logoY 
    Rectangle clip = g.getClipBounds();
    Rectangle logo = new Rectangle(logoX, logoY, logoWidth, logoHeight); 
    // if the logo is outside the clip, ignore it 
    if (clip.intersects(logo)) {
        g.drawImage(logoImage, logo.x, logo.y, null);
   // paint the rest
}you could use BufferedImage.getSubimage(x, y, width, height) but that is an expensive operation. the next option is to use repaint(x, y, width, height)
