Syntax:public GmagickDraw::getstrokeopacity (void)
Parameters:this function takes no parameters.
Return value:this function returns a double opacity description.
Errors / exceptions:this the function throws a GmagickException on error.The following programs illustrate the
Gmagick::getstrokeopacity() function in PHP:
Program 1:
// Create a GmagickDraw object $draw = new GmagickDraw();
// Create a GmagickPixel $strokeColor = new GmagickPixel ( ’Red’ ); $fillColor = new GmagickPixel ( ’Green’ );
// Set the opacity of the stroke $draw -> setstrokeopacity (1);
// Set the width and height of the image $draw -> setStrokeWidth (7); $draw -> setFontSize (72);
// Function for drawing a circle $draw -> circle (250, 250, 100, 150); $gmagick = new Gmagick(); $gmagick -> newImage (500, 500, ’White’ ); $gmagick -> setImageFormat ( "png" ); $gmagick -> drawImage ( $draw );
// Using the getstrokeopacity() function print_r ( $draw -> getstrokeopacity()); ?> Output:1
Program 2:
// Create a GmagickDraw object $draw = new GmagickDraw();
// Set color $draw -> setFillColor ( ’Green’ );
// Set the opacity of the stroke $draw -> setstrokeopacity (0.5);
// Line drawing function for ( $x = 0; $x < 40; $x ++) { $draw -> line (rand (0, 100), rand (0, 60), rand (0, 500), rand (0, 500)); $draw -> line (rand (0, 100), rand (0, 60), rand (0, 500), rand (0, 500)); $draw -> line (rand (0, 100), rand (0, 60), rand (0, 500), rand (0, 500)); $draw -> line (rand (0, 100), rand (0, 60), rand (0, 500), rand (0, 500)); } $gmagick = new Gmagick(); $gmagick -> newImage (500, 500, ’White’ ); $gmagick -> setImageFormat ( "png" );
// Set color $draw -> setFillColor ( ’Black’ );
// Set font size $draw -> setFontSize (25);
// Using the drawimage function $gmagick -> drawImage ( $draw ); $gmagick -> annotateImage ( $draw , 5, 120, 0, ’ GeeksforGeeks: A computer science portal’ );
// Show stroke opacity echo $draw -> getstrokeopacity();
?> Output:0.49999237048905
