Add rectangle fails

Post by rustydiver » Fri May 03, 2013 7:16 pm

The code below from this thread -- http://www.teechart.net/support/viewtop ... 11&t=12762 does not work.

Code: Select all

    $chart1 = new TChart(800,600);
    
    //$chart1->getChart()->getAspect()->setView3D(false);  //it seems to break the custom drawing brush


    //****  RENDER RENDER RENDER  ****//
    $chart1->render("chart1.png");

    $g=$chart1->getGraphics3D();
    $g->getBrush()->setVisible(true);
    $g->getPen()->setColor(Color::BLACK());
    
    $g->getBrush()->SetColor(Color::BLUE());
    $g->Rectangle(new Rectangle(10,10,100,100));

    $g->getBrush()->SetColor(Color::WHITE());
    $g->Rectangle(new Rectangle(170,170,270,270));
    
    $g->getBrush()->SetColor(Color::RED());
    $g->ellipse(400,400,500,550);
    
    imagepng($g->img, "chart1.png");

    $rand=rand();
    print '<img src="chart1.png?rand='.$rand.'">';
It produces a blank chart preceded by.. (similar to the save image to file errors)

Hi,

Excuse us for the delayed reply here.
I could reproduce the problem so I've added it to the wish list to be further investigated (TF90016569).

OK... you notice that the errors are too similar to the save image to file error to be coincidence, right? "247 is not a valid..."

Hello,

yes, this is the same problem as in the other post. For the moment the best way I can think of if to remove the "imagedestroy($g->img); " from the render() method of TChart.php file. Then you should be able to make it work (also a good example could be the EventsDemo.php of the Features example project (at Miscellaneous folder).

In the case you want to create several charts you can always call the following line after all has been displayed :

Code: Select all

imagedestroy($chart->getChart()->getGraphics3d()->img);
