Question

I would like to draw a rectangle at an angle with PHP. I know that you can draw rectangles with PHP using imagefilledrectangle but how to draw it an an angle.

public function drawshelf($x1, $y1, $x2, $y2, $width, $angle = 'false'){
    imagesetthickness ( $this->canvas, 1 );
    for ($i=0; $i < $width; $i++){ //HORIZONTAL
        imageline( $this->canvas, $x1, $y1, $x2, $y2, $this->color );
        $y1++; $y2++;
        if( $angle == 'true' ){ $x1--; $x2--; }
    }
}

I wrote this function to draw it using lines and a loop but its not coming up right like the red box.

Can someone please tell me what am i doing wrong? And can you even draw it like that?

Answer 1

Use imagepolygon() or imagefilledpolygon() to draw non-rectangular shapes using GD. You may need to review a bit of trigonometry to figure out how to position the points to get right-angle corners.
